Cheap battery on EBAY

Has anyone bought any of the cheap batteries off of ebay. I would like to know if you have problems with them and do they last as long as the orignal ones. thanks

Actually the one I have has a bit higher MaH rating than the Orig, and lasts a bit longer. I have had no problems with it..

Mine is just as good as the original. It comes with a fancy charger ( disco light when charging), and usb charger, and carry a one year warranty.

Which one did you all buy from Ebay?

This one.
http://cgi.ebay.co.uk/wk/eBayISAPI.dll?ViewItem&Item=190138129526
But I see some other similar items selling for even lower price than what I paid for.
For example, this one:
http://cgi.ebay.co.uk/2200mAH-Batte...4075008QQihZ016QQcategoryZ15034QQcmdZViewItem
I guess it's only a battery, so should not cost that much to make, especially when all of them comes from China these days.

Yup i will just keep a backup battery incase something happens.
btw this is one heck of an amazing item - http://cgi.ebay.com/B002-AA-Battery...ryZ15037QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

Looks cool.. To bad the USB port requires 5v to charge the Athena, and 1 AA batt. is only 1.5v, so I doubt that item even works. Looks like it might be a scam outta China.
Hell, the picture, isn't even an Athena/X7500/Advantage..

I had one of those AA chargers which I used to charge my Universal around a year ago, although I've since lost it. It converts the 1.5v from the battery to 5v, and does work. Sucks an AA dry pretty quickly though.

cheap yes, FAKE X7500 Sanyo battery
If it comes from this guy it is a FAKE, badly made copythat does not fit the supplied charger!
I have 6 pictures to show the differences!
e-mail: [email protected]
and he pretends it is "just from another factory" when the label says Sanyo!
this is his details:

you can convert 1.5 volts to 5 volts if you change the I and R of course the device really only needs 3.7 volts to run the rest is for charging the battery
FYI - V=IR and of course the reason this is kinda of a scam is P=VI so 1 AA battery can not really provide that much wattage cause it can't provide that much current

Ok how about 4 AA batteries? 2700mAh each? The thing is my car cigaratte lighter connection is loose so it doesnt charge my electronics anymore. Although it gets hot really not sure why its not charging.

[Q] Wind up/Dynamo charger

Does anyone know a wind up/dynamo charger that works for HD2?
I found quite a few such chargers on ebay, but without any output voltage/current specifications.
Thanks!

Do you have any link ?
What about charging time, turning the dynamo....all night long for a two minutes call ;-)
Outpout should be 5 V / 1000 mAh
Input is muscles !

The 1st one has 5.5V and 600mAh, while the others don't have specs.

wish ebay got some tiny urls...meh i think they would do for emergency...nothing else. manage to get 1 or 2% after 5 mins of hand work

Not for the HD2 but i bought one for my diamond. I found it actually discharged the battery! Winding the handle the diamond displayed that it was charging and i could feel the rotational load increase as the phone started drawing current. However after 5 mins of winding my phone was 1-2% less than before 'charging'!

The same result! I was miffed. I thought that maybe the charging circuitry takes some of the power to operate and that the charger wasn't even providing enough for this, therefore it was drawing the rest of the battery and in turn depleting rather than charging the battery. I'm not sure why this was just my guess (and i'm an electrician )

well guess that answers op's thread
i remember when i was in school for a construction project my class mate was making a wind electricity fan from wood with a dynamo stuck on the tri wing when we tested how much power it produced when spinning it as hard as we could it was producing - power couldn't even light a bulb to show its working haha
guess the same **** here...just probably not going fast enough to power it properly or u want to be superman

Well, I thought about getting a solar charger, but I want something that will charge my cell anytime and not only during daytime or sunshine.
Although, if I don't find a wind up charger, I might end up getting a solar.
So, which one do you suggest? Have you tried it?

there are some solar chargers that can keep the charge in its battery, so even u don't have sun, u can charge it later.
i tend to buy this:

which is quite cheaper ($6.14) and has the proper specs (5.5V, 1000mAh) for HD2.

I bought a spare battery & USB charger (Ebay; never had any regrets), as I do with all my earlier smartphones. USB cab be from car, computer, photovoltaic panel or mains unit.

get powermonkey eXplorer or powergorilla if money is no problem
those are the best you can get.
very rugged, quality 100.
I bought powermonkey explorer 3years ago, its still running great.
this summer bought powergorilla and solargorilla to charge it while its sunny.
I love these gadgets! you can charge them ANYWHERE international chargers, usb, solar etc...

Thanks for the info, but the price is quite high...

Another useless gadget
Well, slightly offtopic, but the thread was the closest I could find to post the following.
Recently i bought a wind-charger while on vacation in Paris (a charger that uses wind power while you bike for example to charge itself and then you can charge different devices with it).
And here is my negative review for it:
Well, i was very excited to buy this gadget (costed me 30 EUR). I bike a lot and this was also meant to be used for outdoor hiking activities.
But..
First of all the lack of any type of power meter renders the device unreliable to the point of uselessness. You take the charger outdoors (with a 1200 mAh battery inside) and you have no idea how much of the battery is filled(unless you pre-charge it from mains). But then, if i needed just an external battery, there are definitely better and smaller choices.
Second: You cannot pre-charge the charger from mains and charge the phone simultaneously, nor you can charge your device "on the go"-directly from wind..
Third: You cannot turn on the quite weak led lights in front of the device and charge it simultaneously (so, for example if you bike in the evenings when it is late, you have to chose, either you use it's light for safety, or you charge the device. Ridiculous)
Forth: in the description on Uniross site it is said "Can also be charged through a computer or through wall plug". Well, it can be only charged using supplied wall plug, no wire for computer charging..
Fifth: When fully charged from mains it will charge my discharged HD2 only to 60%, which means that it is less then 60% effective in transferring the charge. Also make sure your device will agree on some 500 mA of charging current (most of them will probably)
Sixth: It does need quite strong wind to charge, it starts to charge when your speed (in no wind condition) gets around 15 km/h. People say it needs some 15 km of ride to be fully charged. How they managed to estimate that the charger is fully charged - i have no idea.
Seventh: The charging indicator (which tells you that the speed is enough for charging), is placed right in front of the charger, so to check whether it charges you have to dangerously lean forward or ask the approaching bikers if they see a green LED light- truly stupid design flaw.
Eighth (the most annoying and stupid): YOU HAVE TO CHARGE IT FROM MAINS FOR SOME 20% BEFORE YOU CAN START CHARGING IT FROM WIND!! Can you imagine how dumb this condition is.. first - there is no way to know how long should i charge it from mains to get the necessary minimum 20%. Then, when i am outdoor and lets say charging the phone - if i use all the juice - the charger will become useless, as there won't be a possibility for another startup charging. Then I have to charge till it is decreased to 20% and use the wind to charge it back. HA! there is now way to know that it is on 20%,10% or 30%... how dumb the design and functioning can be... This is truly a raw device they let out on market. Shame for Uniross.
(i will stop here because it is too late...)
I wish i would have read a review like this before i went and got this piece of ... something... Hope it helps someone else.
Attached is the picture of mine in packaging

Anybody tried Solar Powered Battery Chargers?

Hi Guys,
Anyone tried Solar Powered Battery Chargers?
Looking at this one here :
source : 6000 mAh Solar Powered Mobile Power Extended Emergency Battery - Obostore

I'm looking fior the same. I bought recantly GOAL ZERO Nomad -7. Instead of charging it drains the power of my Note-2. I guess it is because of the non-standard pin-out (11 pins), so this is the one I would definitely not recommend.

I haven't seen any positive reviews about any solar powered chargers. The problem is that you need to apply voltage (bias it) in order for it to work. Like those solar power panels on the roof of people - if you loose a power to the house, they will not work So they might be draining instead of charging lol!!!
Don't know for sure how it works and if it works and how efficiently. So if anybody has any real life experience, please chime in. Most of the big name external battery vendors don't want to carry this product. I only seen it on ebay and Aliexpress.

I personally haven't tried one. From what I've seen about them, they're very fast, and can be nick-picky about the angle to the sun. On top of it, you'll probably need to check what's the output versus what the phone needs to change.
I think you're probably better off finding some kind of crank mechanism and use that to change the phone. Plus, you'll get a little work out too; you'll live longer to enjoy your phone, 8)

I have a voltaic that I use when camping or on extended hikes. It comes with a 3000mah battery. I haven't used it on the Note2 yet, but used it a lot with my Fascinate. The battery works fine as backup power, though it charges slowly and the phone pretty much has to be off for it to be effective. It takes most of a day of full sun to recharge the contained battery. It's ok if you're going to be away from power for a week, but for less than that I think just an extra battery or two fully charged would work better.

I think we just need to find or build one that supports 2.1 amps (ideally) but anything over 1amp should do something.

I have one I found at Best Buy a couple years ago. It's a single amp box, so charges my Note II very slowly. I've used it on my bike when I'm out on rides. I have a mount for it and my phone. While riding, I use bluetooth headphones. It does work, but like someone else said, there needs to be one with 2.1 amps.

I as well have a Nomad 7, but mine charges my note without issue, although I will admit, it is impractically slow.

I bought this couple of months ago, charging the phone is a wii bit slow but it works like a champ!
http://www.ebay.com/itm/Opteka-4000...iPad-iPod-Android-Phone-Charger-/370665663271

I wouldn't mind if the solar power was a "backup" to a regular external battery, but if all it did was solar I wouldn't be interested.

WICKED... just stumbled across this on ebay. If you are a roll your own DIY type and want to charge a rapid charge device like Note2 or a tablet or something, this might be a great thing to look at.
http://www.ebay.com/itm/DC-DC-5V-36...018?pt=LH_DefaultDomain_0&hash=item2c700c47c2
I, personally, don't like the mini-usb connector... seems kind of goofy. I'd prefer just two wire terminals to connect solar panels to.
But yeah, if you've got high voltage solar setup... e.g. anything between 5V and 36V and want to have a clean, regulated 5V usb compliant output, this would likely be your guy. I'd also want to make sure it really does work with note2 - in terms of negotiation of currents higher than 100ma. YMMV FWIW
AND if you don't need note2/tablet 2A...
this guy seems like about the right fit.

(poll) POGO CHARGER WORTH IT?

Hey guys so lately there's been a lot of discussion about the pogo charger.
I've checked all the threads and more than the value of the charger, the forums are filled with shipping complaints.
I can't seem to sort out the opinions and real comments on the pogo.
As such, for those really on the fence about getting a charger (like me) I made this poll, since there was one on screen protectors to help people choose.
Any comments made, please make constructive opinions on if you have a pogo charger, if it's worth it, etc. (not on your shipping problems please)
Thanks!

I only bought it because I thought it would be able to charge my tablet while under heavy usage (1.7GHz performance gov + full brightness), and sadly it doesn't even seem capable of doing this.

I seem to remember somebody stating that under heavy usage they've saw a current drain over 3A. If your situation is the same, nothing is going to keep up with that which is over the max of the charging circuit. It's simple to test for that.
The POGO cord charges faster but stops during OTG usage, no ROM/kernel Dev's have tried to solve this issue so far. There may be another issue with cigarette lighter type power supply also.

Shipping just took time from Korea, now they have a US shipping source through Amazon.
I really like it, saves wear and tear on the USB. I charge at night, and never have enough time to use it that I run the battery in a day. The OTG complication is annoying, but liveable, and hopefully likely to be solved.

I like the reduced wear on the micro usb connection and additional safety of quicker disconnect if cord is yanked from tripping. I charge the tablet at night, so not too concerned whether charging is quicker. I would love to see some ideas on how to improvise a charging dock using this cable!

I think whether it's worth it totally depends on the reason you want it. If you want to use OTG while charging or to do data transfer, it's obviously a bust.
These are the reasons I'm very happy with it, in order of priority:
1) Saves stress on the USB jack, especially if dropped or banged against something.
2) Easy to click onto the N10 when I'm done reading an ebook in bed at night and I'm sleepy.
3) Charges a bit faster than USB.
If you're looking for a miraculously shorter charge time then it's not worth getting.

Definitely worthwhile ... it is one of the nicest accessories I've purchased in a while. I purchased it only for the convenience of not having to mess with the mUSB charging. It delivered. My charging graphs indicate that it charges at a faster rate than the mUSB ... just a small extra bonus.

^^ this.
I bought it because I've had occasions where others in the house have messed up micro-usb connections on phones due to using them while still plugged in - with this, there's no way of easily damaging it
And so far, so good! Would really recommend it.

Wow, max brightness ? I find the lowest setting really bright.
I did general usage on lowest brightness and it charged pretty good, IMO.

It was worth every penny and when they come back in stock at Amazon I will order another.
I use my tablet heavily throughout the day and found myself unable to charge it completely while I slept. Now using the stock wall wart and pogo it charges in a fraction of the time. Like I said, worth every penny.

Charges faster, but was it worth it for me? Still undecided. The main reason for me getting it was to plug a HD into an OTG cable and still get power to the device via the POGO. Unfortunately that will not work. The POGO will not charge when running OTG. Shame.

Back in stock on Amazon... Just ordered one tonight. I'm interested for two reasons. Slightly faster charging (not a big deal for me, as I generally plug it in at night, and use it much of the day), and I also like the idea of the pogo connector instead of using the USB socket every day. Should have it in 3 to 5 business days.
... beamed from my Nexus 10 to your planet

Just ordered one off eBay, should have it by the 20th at the latest. I spend a lot of time driving so carry the Nexus 10 around with me in the car and I've bent the USB plug on the cable so though I'm better off getting the pogo charger incase I damage the USB port on the tablet

Answer- Yes it is but...
Just got the pogo cable on Friday and did some testing over the weekend and have some results and observations.
I ran my N10 down to 10% Saturday and plugged in via the pogo cable at about 11:30pm. . When I checked Battery Monitor Widget the following morning it showed fully charged at 4am. Total time 4.5 hours. Max charging rate was at 1916mA and tapered to 415mA.
Sunday I did the same, (11% and 11:30pm) and used the USB cable. A check of BMW showed the N10 fully charged by 5am. Total time 5.5 hours. Max rate was 1559mA and a taper to 420mA.
So, an hour faster. Not huge, but significant. Overall I think the important thing with the pogo cable is that it will charge as you use it. When I plugged in with it before I turned the screen off I was showing a net charge, while with USB it continued to discharge, albeit slower.
Both of these (admittedly unscientific) tests were done with the OEM charger and USB cable.

The pogo charger is a great way to save the USB port of the Nexus 10 if you have young kids. Since the pogo charger is magnetic, there no way to damage the tablet when a toddler yanks it off a desk while its charging. I am very happy with my pogo cable. Bought it off amazon and got it in 2 days.

[Q] HTC One Restricted Charge Rate?

Here goes.....
I've been struggling with charging this phone. I have both the Sprint and the T-Mobile versions and I'm seeing the exact same thing with both. This phone simply won't pull more than roughly 600ma from a charger. With the best of equipment (chargers, cables, clean regulated power, etc etc) a ~600ma (+/- 15ma) is all I ever see at max draw.
I've tried all sorts of chargers including several stock. Same for cables. I know some cables are crappier than others and can restrict current....those that I found did that were tossed in the trash (don't want to keep the fubar cables anyway).
The phones have been in various states of operation too....from one extreme to the other....under heavy benchmark load to "first run" state from a complete reset (full wipe) with airplane mode on.
I said I have a "problem" above. What I mean is that my use-case is such that I use navigation with bluetooth streaming for podcast listening during my commute to and from work everyday. While I'm at work I plug into my TV to playback video podcasts via MHL. At best.....BEST....I can maintain my current state of battery. In other words, if I'm 39%, it'll stay thereabout when I'm plugged into a charger in either case.
No..."Power Saver" doesn't help. What I think would actually help is if power saver had the ability to disable some cores in addition to just governing to 1.1Ghz across all four.
To have a kickass phone that you really honestly can't truly kick ass with feels weird. This thing simply discharges faster than it can charge under any real world load. Maybe my personal use case is unconventional but I feel like it's not THAT unconventional seeing as that the features I use wouldn't be built in if no one ever used them, ya know?
I first noticed this behavior with my previous phone, the EVO 4G LTE. Even though the behavior was there, it wasn't as bad or noticeable due to what I think is the fact it was only dual core...maybe other factors too. But I'm not a developer/engineer so my observations are only from the outside looking in.
I know I can "tweak" my behaviors -- "...do this, or do that. Disable this, or disable that." I understand these things. But having to disable a bunch of things sorta goes against the idea of having this device in the first place.
At the end of day, my observations are my own and I know some are going to suggest I'm "holding it wrong" or whatever, but you guys gotta admit there's something up here with the very limited charge rate.
All that said, I still enjoy the phone. :angel:
PS - I've been using this to monitor current/voltage. The tool has been verified to be working properly by two EE's at my work.
http://www.amazon.com/Micro-SATA-Cables-Voltage-Current/dp/B005Z1E3IY

The stock charger. How much does that one show it pulls?
Because I have a 1a charger for my car and I can have the screen on the entire time and it charges, slower, but it charges.

Same same.....doesn't matter the charger capability. Peak draw at any one time seems to be roughly 600ma...+/-. As the charge of the phone gets closer to full, the rate tapers off to roughly 200ma and then to about 80ma as it gets really really close.
I know HTC is trying to protect the battery, but I really get the feeling that this is way over-protective.
I took a picture with my Sprint ONE of my T-Mobile ONE on a 2.1amp wall charger. Notice, at roughly 1/2 charge, it's only pulling about 600ma. Too daggon slow in my opinion.

I assume you mean a 2.1a charger from a Samsung product, that won't work. Samsung uses some signaling on the D+/D- wires to show "This is a Samsung product, charge at 2.1a"
HTC One does not have the ability to offer this signaling and thus will charge at usb rates of 500-600.
Some products short the data wires of the USB to signal that it can supply extra power. This is the type of signaling the HTC One can use. You would need a charger with this capability.
If you don't mind, if you could take a picture of the same setup with the stock charger, that would help.
EDIT: This particular device you've linked seems to block any signaling, according to the reviews on Amazon. I think your problem may lie there.

I understand what you mean. Note that in all my rambling on about various cables and chargers, if I wasn't explicit, I was implicit in that I've tried HTC stock gear too. Same results, no matter.
I do own and did try a few Samsung chargers and cables in addition to the myriad of others. I'm aware of Samsung's irritating attempts to lock people into using their accessories, thus the signaling modifications, but wanted to try them anyway. That's why I used a whole bunch of different chargers and cables. Some are not-so-good and others are great. The one charger I prefer is from VENTEV. It's a dual-port 4.2amp (2.1/per) wallwart.

What I'm saying overall is that the big picture here suggests that we can't pull more than the peak 600ma or so charge rate, no matter what combination of doo-dads you toss at the phone. I'm all in if HTC has some super-secret special vapor rub one can use to charge faster, but even the stock charger they give us in the box which supports 1AMP doesn't deliver that since the phone itself doesn't pull more than what I've seen.
In the attached pics, the one of the charger is the Ventev. The other three show my T-mobile ONE just hit 90% charge and the rate has dipped to about 400ma on average. I took three snaps to show that it does fluctuate a bit. It'll ramp down more at about 95% or so and even more at 99%...................ALL of which is to be expected, I know.
To be clear, at this point, and what you see in these pics, is the stock HTC wall charger that we all get in the box with the phone, the stock HTC microUSB cable, and the measuring tool that is plugged into charger which the cable is then plugged into to then charge the phone. The meter can handle just over 2amps before it pops the internal fuse.

I was directed here from another section of the forum. Have you tried using this?

With the stock charger it's telling me that I'm pulling in just under 950mA during peak charging and tapering off as it gets full.

i used a samsung 0,7C charger and it charges at a conntat +800 mah
the HTC chargers also sometime speaks a 900mah + but typically aroung 200 - 700 mah +
it seesm t fluctuate more often than the samsung which fluctuates to a lwoer range when bnearing 100% charge.

Dude, I have the same problem with my EVO LTE, exactly as you describe it, but for some weird reason, my car charger charges my phone normally while other chargers will take several hours to fully charge. I really hope it's a problem with the chargers and not our phones :thumbup: :thumbdown:

Hi. So based on what people have posted, does this mean that there isn't much difference charging it from the wall socket and from a usb port in a computer? Since then charging rate is around 700-600mah and a usb charges at around 500mah

So I download that app, and no matter what I do with my settings, I cannot get my phone to charger faster than about 550mAh. I am currently running at 384MHz CPU, 200MHz GPU, and Force Charge (On/Off), and 50mV undervolt. With the phone just laying there (screen on 65% battery), as I stare it currently saying +529mA (+23.00% /h).
I just tried playing a game, with those same exact settings and it stated charging at +217mah.
