Seller with 2000mah Andia batteries (OEM Size) back in stock

I know I wasn't the only person waiting on these:
http://cgi.ebay.com/2000mah-Spare-Battery-for-HTC-Touch-Pro-2-T7373-Sprint_W0QQitemZ230441767652
And yes, for you who click on this thread without knowing what they are, Touch Pro 2 batteries are the same size/shape as hero batteries and work just fine in heroes.

Thank You!! Finally, I just bought the battery -- will wait patiently. I have the Mugen 1800 and I haven't been very impressed, hopefully this one doesn't disappoint. Though, for $10, it's a steal.
EDIT:: Just bought 2 actually!

After I purchased I recieved an email with a link to Delivery ETA stats. These are coming from China:

I received the Email as well -- basically about 2 weeks is the ETA, not too bad. That was the same for my Mugen battery as well.

In for one.

i just got one also
thanks akijikan for posting the link

thanks for link, just grabbed one myself. For $10, why not?

thanks
Thanks for the link. Just ordered 2. I will compare to the Mugen. So far I am unimpressed with Mugen 1800.

ordered 1.

Im in myself.

Alot of our products , especially electronics come from that region. they are massed produced for under 1.00. One reason they are offered so cheap,but Quality is where we lose at times. Please keep us updated as far as usage. For the price it def makes a great spare

I don't know... I bought a Mugen 1800 battery, conditioned as the directions stated and yet my results aren't very good. I'm not the only person having this problem. And, I keep hearing from the other thread (Mugen 1800) that these $10 batteries are lastly far far longer than what I have.
I paid $32 for the Mugen, I'm willing to give this a try. You could say that because the batteries are made so cheaply that they might be of lesser quality, but whose to say that the Mugen isn't mass produced at the same $1.00, the only difference here, to me at least is that the Mugen is being sold at a much higher price point when it comes to retail sales.
But I will report my finds upon getting the battery.

I'm not a major battery wiz, but milliampere-hour (mAh) is a rating of hours per the draw of device... not an exact measurement of capacity of power
http://en.wikipedia.org/wiki/Ampere-hour
so you change the hardware, the mAh is GOING to change. the voltage draw may be the same, but the amp draw might be different depending on the requirements.
Just keep this in mind when you're thinking that just because it says 2000mah for and hd2 that it's any better than the 1700 and 1800mah for the hero, or even the stock battery. Remember it's a RATING per load per device, the mah standard was created as an easy way of telling estimated time because putting the actual capacity of a battery would just confuse and would be easily manipulated. Depending on the point in which you can drain a li-po li-ion battery to where it becomes phyically damaged and will not charge anymore below 2.8v. most batteries report "dead" when they drop to 3v so that you don't over discharge it. Allowing your battery to drain from 3v to 2.8v could allow for a longer "rated time" but would be by no means healthy for your device. this .2v is your grace period to allow for natual envroinmental discharge in between times away from the charger.
http://en.wikipedia.org/wiki/Rechargeable_battery#Active_components
With the added dollar amount of $10 I'd be VERY warry if it is as good, or even safe for that matter. Just be warned... and don't be surprised if it does damage your phone that sprint doesn't honor the warranty you just voided by putting an un-reccomended power supply into your device.

Duly note. Now... Cant wait for my new battery!!

If you guys are wondering how they perform, the short answer is great, and a lot better than stock. The long answer is, go check the mugen 1800 thread. A couple of us who have been testing the battery have posted some reviews there.

no name battery
I bought a couple batteries like this for my Apache back in the day. They did work about the same as the OEM although the MaH rating was higher. I would think that the quality control of the more expensive batteries would be better and likely the characteristics are closer to as promised. Additionally, what I remember was that the durability of the battery was shorter but given the price it was still a worthwhile purchase.
It would seem that the quality of the HTC branded batteries and the Mugen are better than these.

I understand that products can sometime vary from electronic to electronic. Its just how it goes. I guess I am just one of those consumers that is willing to try something with such a fantastic price that I am willing to throw it away if it isnt what I expected. So far the folks that are using this battery are showing no signs that it is physically hurting their Hero so why not? If it doesnt give extended battery life then oh well, no harm no foul on 10 bucks.

Ok, seeing it that the stock battery is Lithium Ion, this also applies to it as well. Just because it has HTC written on it doesnt mean it is anymore sturdy than any other company. I have seen images of laptops with stock batteries that have burnt holes through the PC from overheating. The chance is always there no matter what route you take.

Agreed! Toshiba, Sony, Mac? Almost all laptop batteries are prone to overheating or exploding... mainly because people leave the power cord plugged INTO there laptop, when the battery itself is fully charged, lolol. I just have to do a *faceplam* every time I see that here at school.

10000mAh external battery

Did anyone ever see this?
www.amazon.com/New-Trent-Extreme-Pack-IMP1000-Blackberry/dp/B003ZBZ64Q
10000mAh? Powerful!

Haven't seen that one but I do have the Proporta USB Turbocharger 3400. It works great and supplies about a days worth of power - highly recommended.

Hmm...
'Ultra reliable Lithium-Ion battery, 600% iPhone 4 Battery life, 100% 3G iPad battery life'
so the iPad has a battery of 11000mA????? Don't think so.

I think these kinds of things are great if you're camping or traveling. The 3 reviews on Amazon would make me cautious until it's had more feedback.
One tends to learn as much from negative feedback as from positive feedback (especially since there are companies that get paid to give positive feedback).
Edit: Just found this at half the price:
buy ((REMOVE THIS PART)) .com/prod/energizer-8000mah-universal-battery-pack-w-ipad-tip/q/loc/111/216795526.html

I just got the device today, and as I will be out all night, I will make a field test report in the morning to report on it's performance.
First review: Barely pocket sized and heavy. A good indication
Capacity listed on back: 11,100mAh, 3.7V (41Wh)
Output: 5V, 1A
Input (charging): 5V, 2A

For 1/3rd the price, I just cobbled up a 2-D cell battery holder powered with 10,000 mAH Low-Discharge NiMH and wired them up to a circuit board that I puleld from one of those Energizer Pocket Chargers (the things they normall bundle with 2 AA Lithium Cells).
I bolted a belt clip on it, and I'm good to go-and in a pinch I can always slap in a pair of Alkaline D cells.

I never thought of that.
But an update on this product. Turns out, you can't leave it plugged in to the wall all the time. Mine died because of that. I sent it back and am awaiting a new one.
But the performance is really good on this thing. This thing sat through 12 hours of continuous use and wasn't near dead when I was done.

I use the PowerTraveller device which is pretty good. It holds almost twice the charge of the phone, and has been a lifesaver twice in my month-long owenership. The only flaw is that it does not seem to turn off if you unplug the phone = discharges if you forget.
That said, for £34.99, it is useful on the go.

One of the reasons I avoid those LiOn packs is that when the battery packs die you're sorta screwed in trying to find replacement cells-and based on my experience, I've yet to see LiOn cells last more than 300+ charge/discharge cycles. That's why I still have as my primary Bluetooth headset a Motorola H300 that takes AAA cells. Sure it may not look sexy-but I don't have to pitch it when the cells crap out.

WOW! this is brilliant! could you please post a photo (kind of manual-type). What is the brand of your 2Ds? Aslo, could you please provide some review/technical feedback on how it behaves? How long it charges? how many full cyclescan it go for?

The D-cell holder has a belt-clip bolted on to it. The circuit board from the energi-to-go is hot-glued on to the top of the battery holder. When the phone is plugged into the pack, the blue LED blinks through the hot-glue.
I expect that I'll get hundreds of cycles from the thing.
I have a smaller lash-up using two sets of AA cells wired in parallel. With the NiMH AA I get about 5-10 charge cycles using Sanyo eneloop AA's depending on the discharge of the phone.

thanks again

Thanks again for detailed explanation! I will try to get the "ingredients" and try to assemble on my own.
I had an urge of buying Energizer Energi-To-Go before, but then i learned that it cannot be used with rechargeables. Is it true?
Correct me if I am wrong with following "naive" calculations - 2 D cells 10000 mAh, 1.2 V each as source and 1280 mAh, 3.7 V HD2 battery as a subject. Assuming the conversion efficiency is somewhere around 80% one gets 0.8x(2x10000x1.2)/(1280x3.7) = 4 for number of full charges of dead empty HD2.
Is it what you experience? (actually that is what i meant under query for number of cycles)

Having ordered from newtrent before, I can say the IMP products work well. I bought one for a collegue, she got 3 full charges off her IMP500 before having to recharge the battery.
They're decent products, well packaged and they do give a decent battery life.

Older NiMHs cells probably don't have the same load characteristics as the low-discharge cells do-I have used low-discharge cells with the stock energi-to-go and can usually get 2 cycles depending on the state of charge of the phone. However, my Nokia N900 does need a higher input voltage to kick the circuit over-in that case I slap one alkaline and the NiMH and all is well.
I usually don't let the phone get to a complete dead state-that tends to make charging much more challenging. What I have done is I created a cutout in my case where I can connect the headphones and power.

[Q] Extended Batteries

So I searched around and all I could find was one $80+ battery that came with a new back cover.
Anyone have better luck?
Sent from my SGH-i917 using XDA Windows Phone 7 App

WP7 app testing... sorry

I believe the Samsung Captivate's battery (or any of the other Galaxy S batteries) will work with the Focus. There was a thread about it a few months ago but I couldn't find it and I have not tried it myself.

They do work, I use a spare battery I have from when I had a galaxy s on sprint.
Sent from my SGH-i917 using XDA Windows Phone 7 App

I don't want a spare. I want one with double the capacity :-D
http://www.jpitta.com - Sent from my SGH-i917 using XDA Windows Phone 7 App

Mugen do a 1600mAh battery that uses the OEM battery cover and a 3200mAh battery (more than double the capacity) that comes with a replacement rear cover. Turns your beautiful slimline Focus into a brick tho'.
Also no way I'd be paying $100 for a spare battery, I'd rather buy a couple of stock spares to swap in for far less money and keep the beautiful profile of the Focus.
Just my 2c.

I didn't buy the focus because its thin. I bought it for the screen + expandable storage that doesnt work yet.

It'd still be nice to keep it as thin as possible though, right?
Either way, doesn't look like there are many options out there... The Focus seems like a fairly popular device all things considered, but HTC is simply dominating the WP7 market. Although there are a few Focus specific accessories out there, it looks like the phone may be doomed to seeing a $100 battery from Mugen Power alone :/

Wish there a few more options available. The stock battery is OK, but if you use your phone often, it isn't good enough. I have two extra batteries to help for that issue, but without an easy way to charge these extras, it gets annoying to keep them all full.

I wouldn't expect miracles. Maybe a maximum of 15-20% extra time, but I wouldn't stretch that far
.
On the website the description is more accurate, as on other webites you get "double the standby time and talk time" which is of course, not true.
Quote from Momax website:
* Use the highest-capacity batteries, long standby time, high stability, performance, consistent with the original.
* Advanced Lithium-ion technology, high performance output.
* Battery charging times of up to 500 times or more, environmental protection, and durable.
* Use imported IC components, precision protection circuit board prevents battery overcharge and the positive and negative transient short-circuit, safe, secure.
* Equipped with short-circuit. Overcurrent device in line with international safety standards.
* Production in line with ISO 9002 and ISO 14001 specifications.
Someone here at XDA bought one and I don't see any follow-up which makes me think there's nothing special to expect...

I wouldn't expect miracles either, however I use my phone a fair amount and I usually am forced to sleep with my phone off (which I hate doing). Enough to last through the night would be wonderful.

what's is kijiji? sorry, if its something you don't want to mention in the forum, you can PM me. I'm curious about that 8000 mAh battery. What size, double in height of original one? What brand? Can you confirm it's true capacity by peeling the label off? Pictures? Physically it can't be more than 6400 mAh if its double of OEM height, or more than 3200 mAh if its original OEM size. Really curious about the battery.

it is probably just a chinese copy - just google it - i did a quick search and found someone who got 11 hours screen on time with one of the same size so i thought i would give it a shot, paid $20 for it - might not even be worth that but who knows always can use it as an emergency back up battery - but i will do a test tomorrow from 100% and report back the screen on time

There seem to be a dozen or so out there. I would love to see reviews of any of the batteries listed below. I know from the work I did in this thread....
http://forum.xda-developers.com/showthread.php?t=1753726
...that Chinese batteries are very hit or miss, and there is often absolutely no correlation between the claimed capacity, and the true capacity.
The blunt reality, is that an extended capacity battery could have less capacity than the OEM cell. There were lots of cells tested in the thread above, that had under half the capacity of an OEM. It would be a shame to bulk up our phones with a double-thick battery, only to have less capacity than the OEM cell. So, any reviews out there?
(I'm not against doing another true-capacity battery shootout, this time for extended capacity Note II packs)

you are right it might be even less the the oem battery, i will run it from 100% tomorrow and post my results and some pics of the battery if anyone is interested, btw i am currently running the latest liquid smooth rom and soapkernel with pegasusq governor up to 1.92 ghz, i normally get around 5 to 6 hours screen on time under normal use, sleep is set to 1 minute, nfc is off, location services is on even though i dont really use it, brightness is on auto to the lowest setting - which is fine for me most of the time, i would say if it doesnt get 9 hours screen on time then it is not really worth it other then a spare back up battery for emergencys as it is quite bulky

There seem to be a dozen or so out there. I would love to see reviews of any of the batteries listed below. I know from the work I did in this thread....
http://forum.xda-developers.com/showthread.php?t=1753726
...that Chinese batteries are very hit or miss, and there is often absolutely no correlation between the claimed capacity, and the true capacity.
The blunt reality, is that an extended capacity battery could have less capacity than the OEM cell. There were lots of cells tested in the thread above, that had under half the capacity of an OEM. It would be a shame to bulk up our phones with a double-thick battery, only to have less capacity than the OEM cell. So, any reviews out there?
(I'm not against doing another true-capacity battery shootout, this time for extended capacity Note II packs)

My hat goes off to you!!!! Being a technical/detailed person myself, I absolutely enjoyed that write-up you have done for HTC Sensation. If you can do something like this for Note 2, that would be AWESOME!!!! As a matter of fact, I will let you borrow my Innocell (Seidio) 4500 mAh battery and another 4200 mAh "Gold" which I supposed to get in a few weeks. I don't have any hardware setup to make exact measurements, was just doing relative comparison when I was testing Innocell (check out link in my signature to all my accessory reviews).
Btw, do you mind posting a short write up with a few pictures of your setup to measure batteries? Maybe link to where I can get the equipment as well? I would really appreciate that!

That's a very kind offer!
I'm in Canada though, and one of the realities is that shipping to and from (mostly from) Canada, gets pretty pricey. I thought about doing this with batteries before (so that people could send me their cells for testing), but when I did the math, I realized that for less than the price of two-way shipping, I could just buy a new cell. It's unbelievable, but I can buy a cell from China, shipped to Canada, for a total price (including shipping) that is less than just the postage would cost me to re-mail the same cell to my next-door neighbor.
Maybe for the time being, we could at least collect a few recommendations. I've got a couple cells en-route already. I don't have a ton of cash to outlay on cells for a massive battery shoot-out, but I could certainly buy a couple. Any recommendations?

I use a VA Meter that came from a Chinese gadget site. Out of the box, it is wired to pull its own power from the battery you're testing. The unit can be modified (and I have done so) to take an external 5V supply instead, the benefit being that once the cell dies, the measurement unit itself doesn't loose power. I've run discharges of several cells through this meter, and into a proper hobby charger (set to discharge) in order to verify that the inexpensive VA Meter (it was under $15) is actually accurate. It is. The measurements were within 1% of the proper hobby charger. The reason I don't use the proper hobby charger for measuring smartphone batteries, is that smartphone batteries discharge down to 2.5V before their protection kicks in. Hobby chargers (or at least mine) dislike that practice, and end the discharge cycle at 3V. The setup above, allows me to test all the way down to 2.5V before the battery's protection kicks in.
The funky looking thing with a fan is the test load. It's very much "overkill" for this type of testing, but I use the same setup to test up to 16V @ 2A packs, and that creates heat that needs to be dissipated actively. The circuit you see on the test load is a boost/buck circuit that does nothing other than supply the constant 12V to the fan, regardless of what voltage input it receives. Inside the test load, there are two 50W axial mount resistors, of different resistances, that I can selectively choose to discharge into, depending on what I'm testing.
Finally, those little clip leads are essential for connecting to the actual cells. For the Sensation testing, I actually made a little proprietary clip from a piece of PCB and solder blobs, that I would rubber-band onto the cells. These clips work much much better.

so i have tested the 7960mah battery that i picked up yesterday - i would say it is at least double of the oem battery, i have been using the phone alot today - downloading roms and torrents, xda, etc. so the screen has been on most of the day - you could run the whole day with the screen on the entire time if you really wanted to do and still make it through the day without having to charge it, i am just about to plug the phone into my computer as i need to get some files of it and also want to test out the wireless charging unit that i picked up today and flash a new rom - but here are the stats from today
the phone has been running on battery for 10 hours
screen on time 8 hours
battery remaining is 41%
i would not use this on a regular basis as it is a lot bigger but if you really needed the extra time then it will certainly deliver - the only time i would ever need this much battery is on the weekends when i am downloading alot, etc, so the screen is on almost the entire time
hope this helps anyone that is thinking of getting one decide

Since I'm waiting for 4200 mAh battery, presumably advertised as "oem replacement", I searched a couple more on-line places that sell the same "Gold" battery. Actually found 2 other on-line HK retailers that sell it with an actual disclaimer that its "4200 mAh battery, but you will not get more than 3100 mAh out of it" lol!!! What is funny, even with that disclaimer, they sell 3100 mAh replacement for about $4 while 4200 mAh replacement is $8 and a disclaimer of the same performance as 3100....
@golfinggino: is there a way to peel the label off your 7960 mAh battery? I have a feeling its probably a double capacity "stacked" 6200 mAh battery. Still great to have extra capacity when you need it, although with these double capacity batteries you don't get a good case. Per my review of Seidio's Innocell (link in the signature), they actually came up with a special version of ACTIVE case for their battery, but it's only 4500 mAh rated (although I found it to be of a higher capacity) and I don't understand why wouldn't they make it as a true double capacity.
Also, a general question to everybody, why wouldn't anybody talk about external battery banks?!? Wouldn't that be so much more easier to have a small charged up pack to hook up your phone too for a quick recharge? There are some that deliver true 2A output with capacities of 6 Ah up to 13 Ah and more. Anker, Exogear, and Yoobao make some quality slim external battery banks.

i am pretty sure it is probably just a double stacked batttery as i had one on my original note and that is what it had - i will see if i can peel off the label and check without ruining it - problem is i sell most of the android devices i have within a week or 2 and buy something new so i dont want to rip it all up ! this extended battery lasts alot longer then the extended battery i had in the original note that is for sure

I'm not too familiar with battery operation, but can find my way around electronics
So in theory you have a close loop (without taking into account ext power of VA meter and heatsink fan), with Battery, VA meter, and Rload in series? What is a value of Rload required for this measurement?
And then, you watch VA meter and time it until the voltage reading drops to 2.5V? What is the actual formula to calculate A/h? Do you need to monitor both Voltage and Current through VA meter? I have a regular multi-meter, but obviously can't monitor both at the same time without turning knob dial, and its battery operated so it will time out after awhile. Can a use multi-meter which plugs into a power outlet or do I need the actual dual display VA meter? I guess if you can show me the formula used to calculate mAh rate, I can figure out what I need for this setup.

I have one on my samsung galaxy s2 (t989)
Qcell 3650.
I couldn't live without it. Lasts a full day with heacy use + 4g + auto/low brightness. The stock battery barely made it to noon. I don't know how others can stand it.
I bought two Qcells, one for me and one for the gf. Both have performed well and can be found on amazon for $20 or so with a free cover.
Boy that sounds like a plug, but its not. I at one point was hunting for a good extended battery and found reviews online, so hopefully I am returning the favor for someone else down the road.

Luckily, it's a lot easier than that!
The VA meter, is actually a "VAmAH" meter I don't know why they just call it a VA meter, because it has an actual function built right in for tracking mAH, no math required. The meter knows the voltage that is being dropped across its output, and the current that is flowing through it so it just tracks the mAH as that all happens.
The fan gets it's power from the circuit's output, just like the resistor does. So it doesn't really matter if the fans running or not. If it is, then the load draws an extra 10mA or so of current, which gets tracked just like all the other current going through the resistor. In practice though, I generally don't bother connecting the fact for small cells like these. The resistor is only burning 3 or 4 watts, and that's fine for air to dissipate.
Someone earlier had a question about battery banks / external packs, and why people don't use them. I do, I have a whole bunch. But they're awkward in that you have to carry cables, and connect cables to your phone. I would echo an earlier poster who commented on the shame of connecting a mobile device to wires. The only time I ever connect my smartphone to cable is (generally) on it's first day in my possession, when I have to get it working with custom ROMs. After that, I generally never hook my phone to a cable again - can't stand the awkwardness of wires.

I see. So what is a value of the load resistor, a few ohms probably? Do you by any chance still have a link to that VA meter you got?
With external batteries, I think either Anker Astro 2 (1A/2A, 8400 mAh) or Exogear ExoVolt (2A, 5200 mAh, stackable!!!!!! or Yoobao (1A/1.5A, 13000 mAh) would be my top choices. I would probably think that Anker Astro 2 for $38 is the best solution in this case of price/capacity.
Oh, and I guess you a wireless charging setup then? If so, wouldn't that be only in one place, like home? While you are on a road, at work, in a car - don't you need to use micro-usb cable?

I think I have a 10 ohm and a 5 ohm in there, that I can select between, or parallel or series. In practice I try to deplete smartphone cells at as close to 1A as possible when at full voltage (obviously because of ohms law, the rate drops a bit as the voltage falls).

I got 3 batteries 2 extended and one fake double cell from chinaI got off ebay.
One 7600mAh and anker extended 6200mAh.both from amazon
I ran nova battery tester in short for battery quick test.for the last 3 test.
the first test are uirrelevant due to the fact that that I had no bios for my phone model in nova at the time. That fourth one upis right when I got the anker and found the bios for my phone.then I ran the short test on the
Anker, 76, china at the end. Also I aged my extended 76 and it puts out 10hours continous on screen time.
My 76 I charge in the low run 350 +/-50mA china solo battery charger. 18 hours out put and at lleast about a days use or more . I charge one extended while im using the other but still I want more power I was wonder if any has made their own extended battery mod. Im thinking about adding the two extended battery on the back and putting them in series the make a suposive brickscreen device. With power for a week. Im looking fir easy make series some how .. but I digest.
Heres nova.

Smaller wall Quick chargers

Has anyone come across other wall Quick chargers that are smaller / lower profile than the motorola one? Looking for something a bit more conducive to traveling with.
Thanks!

i would like to have one smaller too

The charger above has a slimmer profile on a power strip than the Motorola "fat" pack (pictured below).

I'm still looking for a charger that is no wider than the typical charger like a Samsung or HTC charger. Something that fits easily in airplane receptacles. Can be as deep as needed I.e. extend off the wall or outlet...
Many protrusions prevent the Moto quick changer not able to seat all the way our at an awkward angle that allows the charger to fall out of the outlet easily.

The slim profile charger I posted above works fine for airplanes. My wife and I went to Brazil for two weeks earlier this month. We flew on 4 airplanes during that time -- Delta Airlines to and from Sao Paulo, and then Brazilian airline TAM to other places in Brazil.

That's interesting because from the photo you posted it looks to be just about as wide as the Moto charger across the face with the prongs. On Delta MD-88 particularly the faces hits the bevels and the blades dont go in all the way to make consistent contact.
MD90 is basically as bad:
But truthfully I forgot that I am holding out looking a QC2.0 true "travel" charger that has international tips. that isn't wide as a bus or at least the tips push the bulk away from the blades. Thankfully they have replaced nearly all those deep recessed outlets that were on B767 which I assume you took to Brazil..
So any ones with travel tips?

The other pictures on Amazon of the one you posted definitely show it look smaller profile on the prong face. So I can see it is in the right size range. now to find an international one.

Just telling you it worked for me.
On the way down I used just the charger, as is.
Coming back, I had high quality Brazilian plug adapter still connected to the charger (from using it in Brazil), so I kept that on while charging on the Delta flight back. Didn't see the need to remove the adapter, and possibly lose it.
You can buy one of those and there's your travel tips.

Another nice thing about the charger I found it is it automatically detects voltage and adjusts as needed. 100 volts - 240 volts. All the outlets in the charging stands at the Sao Paulo airport were 220 volts, while residential Sao Paulo uses 127 volts. Before I plugged it into the airport charging stand, I went back to the Amazon description just to make sure I wasn't about to burn up my phone or the charger...

Those things are BULKY lol. But yea they would do the trick. The best part about these higher quality chargers is that they can accept that wide voltage window without an external transformer. a la the old International Blackberry chargers. So if they just made them with the interchangeable tips there'd be nothing else to get. I need at least the UK, EU, and possibly Australian tips. So it's alot to keep up with when they are bulky like that but I guess I could just use one of those where they slid out different tips from the same cylinder.

and the designer of the moto charger should be smacked for making it unnecessarily larger in awkward orientation.
