[Q] Travel Battery Pack

I am on travel very often and my last experience with my Desire was that when working on the phone with no possibility of charging it, I was left with very little or non battery late afternoon. Any suggestion for a good Travel Battery Pack anyone? One extra charge will do. Thanks

Probably better off getting a spare battery, and charge it up, most easiest way i think instead of carrying aa batteries and charge cases, leads etc.
Just look on ebay and click cheapest first.

Perhaps you are right. Thank you

you can get 3 spare batteries and a charger from ebay for about £10.50, Not sure whar that converts to.

Cheap lol but check the postage time if they are from CHINA
Good Luck
Got these Conversions for you for a rough guide
Sunday, May 1, 2011
11 British Pound = 15.91271 Swiss Franc
11 Swiss Franc (CHF) = 7.60398 British Pound (GBP)
Median price = 1.44461 / 1.44661 (bid/ask)
Minimum price = 1.44461 / 1.44661
Maximum price = 1.44461 / 1.44661
Hope this helps

i use solar charger it has built in 3000Ma battery you can also charge it from pc or adapter and ready to go with extra power. Have it from ebay for $29

Did anyone test any spare batteries from ebay? Thought of getting some, but not sure if it is worth it or not (the charge should at least be as high as the stock battery's) .

Got this few days ago from a china online retailer. Good construction and nice pocketable size. Slightly heavier than LG2X & about 20% thicker. Comes with 0.5A & 1A USB output.
So far, on 0.5A output, no in-charger lock ups yet - which I do get from some AC chargers.
Priced upwards of US$35. Google for "5000mah Power Bank".

will LG come out with an extended battery for the Optimus 2X ?

If they made 2 models. one like we have with a 1500 battery and one that is 1.2-1.4X thicker with lets say a 3000 battery I think almost everybody would choose the slightly thicker 3000 battery model.
These devices are small enough as it is, they should now stop trying to make them smaller as they are surely limited by the screen size, and make them last longer.
I had a Del Axim X50v a few years back that I brought an extended battery and battery cover for, this actually made the device feel better in the hand.

I think the future is not far... for batteries that are either running on gas or like these ones which can be fully charged in less than 3 min. http://green.autoblog.com/2011/03/23/new-battery-technology-electric-vehicles-recharge-minutes/

Well I order mine, but the version with 1 charger and 2 spare batteries (3 batteries is just plain greedy) We'll see how long they take to get here.

would like an option for dock/ battery charger and 2 batteries from ebay but combo NA last time i checked

Does anyone know of a portable battery pack that charges at over 500mah? all of the battery packs Ive seen are around 500mah and that doesn't seem to be enough to even charge the G2X coming from my old charger.

I am using a 5000mah capacity battery pack. It has a USB port with 500mA output and another USB port with 1000mA output. See post no. 8 on this thread.

Only tested twice from over 70% to full on 0.5A. Took longer than using AC adapter. Tried it once on 1A but got a bit hot quite quickly, so I switched over to 0.5A. Also, it takes a while to charge the pack itself from partial empty to full on 1A AC adapter - so I am guessing the 5000mah claim is reasonably accurate.

I bought this item from DealExtreme.
2200mAh Rechargeable Portable Emergency Power with Phone Adapters
SKU: 23734
It works fine, but the input broke after some uses and I had to fix it.

Energizer works best for me... as LG P990 wouldn't last a day with WiFi and 3G active... i have XP2000 and it works great!, the free tip for life is a welcome bonus... I'd post the link but since am a newbie, i cant.
please google Energizer Energi to go or energizer XP2000

best powerbank for note 2

any suggestions??

No idea what you are talking about.

AW: best powerbank for note 2
Powerbanks are external chargers (at least I guess you mean this). I have one with 16000, with this i can also charge laptops. Didn't have any problems yet. The only thing is that the led shows the wrong status as it keeps staying at one dot after some discharge (20%). It's still having the remaining juice though.
Well, it totally depends how much you need, how much space you have for carrying while traveling and how long you plan to be without permanent energy source. You know the best how long the battery would last for your phone usage.

I recently bought an external battery brand anker, I am very happy with the purchase. I can recharge my note2 about three times, more than enough if you will not be near outlets for a couple of days.
Enviado desde mi GT-N7100 usando Tapatalk 2

I have the Anker 10000 as well. This outputs at 2A just like the stock charger, and is not terribly large.

I sometimes almost wish I needed to buy a device like this. Problem is I use about 45-55% of my battery a day. Only long plane trips or maybe camping trips would I need this...

A big use for this is I can power my external 750gb hd for OTG use.

I use one from panasonic at 5400mAh made by sanyo using enveloop batteries, know to lose only a small % of power over a year or two.

I use ProMini 8000.
I like it a lot.
1. Use Li-polymer battery = safe against heat
2. 8000mah, after 3.7v ->5v -> 3.8v conversion.
I tested it can fully charge my Note 2 lte from 1->100% 2 cycles (phone is on but sceen is off) still have a little battery left in it. Could probably charge anothet 10% give or take.
3. 2.1A and 1A output, both are concurrent, so you could combine both to get 3.1A totally concurrent output maximum and stable ampage output, won't drop.
In my test, from 1 to 100% full in 2.1A port took me roughly 2.5 hours to get fully charge.
4.super small and slim for 8000mah
5. All alumimum made chassis, hardly even warm during charge process, nevermind hot.
6. Inexpensive, I bought mine brand new in Hong Kong for USD 56.
Highly recommend!

Review: 11200mah Yooboa Power Bank - any alternatives?

So I purchased this for my note off eBay. Paid about $40 shipped to my door. Impressed by the quality, it looks sturdy and would last a while.
I used battery current tester and only got 600max charge apposed to the 1200 my stock Samsung charger puts out.
This means 4-6 hours charge time instead of 2 and I must say when I use the phone on charge it actually sucks battery.
It's rated at 2amps which was my mistake but unsure if it makes much difference at 2.1amps.
" Input: DC5V---1000mA; Output 1: DC 5.3V?1000mA (Max); Output 2: DC 5.2V?2000mA (Max)
1A & 2A output at the same time, suit charge for mobile phone, Tablet PC, Digital Camera etc."
Does anyone know how I can get 1200? Or can suggest a power bank for the note 2 that can hold a good charge in say 2-3 hours?

I assume you are not on Verizon and using Galaxy Charger Current app to track your current?
OK, here is a scoop on external battery pack you got. Since you bought it from ebay, I can guarantee you that Yooboa is a fake HK version. eBay sellers buy it form Aliexpress retailers in bulk and re-sell it at double the profit. Take a look here: http://www.aliexpress.com/wholesale...00mah&catId=0&initiative_id=AS_20130429044248 - you can get it for $20 shipped free to US (but aliexpress retailers doesn't accept paypal).
There only a few authorized Yoobao resellers in the world, and Kevikev is probably one of the few (if not the only one) in US. Even at his discounted price, this real model cost $55: http://kevikev.com/Yoobao-Long-March-11200mah-Power-Bank-for-USB-Mobile-Device-YB-642.htm
The fake ones look very real but have fake guts. Beside 600mA current you measured (or maybe it's just a typical 500mA pc-usb current?), it most likely is not 11200 mAh but probably half of it, and you also have to take in consideration 30% de-rating on top of it since mAh capacity on external batteries is at 3.7V while it has to be converted to 5V usb output where you loose 25%-30% due to inefficiency.
I recommend Anker and NewTrent external power banks I have tested and reviewed (summary of my review links in my signature). Just keep in mind those mAh numbers in reality are always 30% lower for the actual capacity your phone sees. I also been informed NewTrent will be releasing 13000 mAh slim battery in a few weeks which I'm going to review as well. But either way, Anker and NewTrent are trusted brand names (with a ton of amazon positive reviews) and offer 1A and 2A outputs and also 1A input charging of the battery itself so you can quickly charger your battery pack and then quickly charger your phone as well.

I'm on an Australian Telstra phone.
Used the original cable for those figures which is embarrassing.
Looks like I'm tossing this junk, I'll just go buy one you mentioned.
Thanks heaps for your help

You are welcome. If you are not in a rush and can wait till mid of May, the NewTrent upcoming PowerPak+ might be a good choice since you are after a higher capacity. I only have their preliminary spec but its going to be 13,500 mAh (@3.7V) with 1A input charging, and dual 1A and 2A outputs, and dimensions of 125mm x 68mm x 28mm @ 283g.
Also, as I mentioned in other threads, stay away from those ebay no name 20,000 mAh ext battery bricks...

Believe it or not, i read your reviews and cross checked some prices online.
The NewTrent may be a better battery than the Anker, but its about 3 x the price to get them from US to AUS.
I ended up getting the new ANKER A4 13000mah
1. Because the 3E was the only other for sale
2. They're both USB input so it makes more sense just to go the higher mah rating
3. Its a new model
Paid $60 shipped to my door from ANKER off ebay.
I purchased it for travelling across Europe - i want the option to charge via AC + USB instead of just AC with the Anker 3. I only intend to use it with my Note anyway and bought it because Hostels won't always have free powerpoints.
My last question i was worried about and just bit the bullet with is: How long does it take to charge via AC (samsung stock) ? It says a crazy 8-10hours on the website via USB. I don't want to leave it alone fearing someone will steal it if its 10 hours.
Thanks again - how do i thank you in your other post? can't find the button.

Uh, totally forgot m8, you are Down Under I know it has been mentioned before by others that shipping outside of US for some products could kill the price. Or sometimes you can't even get the product shipped out; there is a thread started by another member from Australia about getting Zerolemon 9300 mAh battery.
I was about ready to suggest another battery from Yoobao (genuine) rated at 15,600 mAh for $60 from Kevikev, but it probably going to cost you arm'n'leg to ship it out. Sounds like you got a great deal on that Anker battery and even after de-rating you should still get 3 full chargers of Note 2. Regarding charging time, just look at it this way, your rating is 13000 mA-hour. The input to this Anker E4 is 1500 mA, and that's how much current it will take every hour so 13000 / 1500 = 8.6 hours. I think it will be closer to 8 hours of charging. Your wall Samsung charger is 2A which means it can supply up to 2000 mA of current which is plenty for battery's 1500 mA input to charge it at full rate. But if you are using a wall charger rated at 1A or an old phone charger rated at 500mA-750mA - your input will be charging at a much slower rate because AC charger will not be able to supply full 1500 mA amount. Probably charging overnight is the best idea if you are worrying about someone taking it away. But these things are so small, and even with stock usb cable you don't have to be next to outlet. Probably put a newspaper over it or something when you are away? These don't get overheat even considering 30% of energy loss.

I paid $49 + $9 shipping - a bargain in my book. All the other batteries are $50 to ship, which is about the price of the unit itself!
I think i will stay away from Yoobao from now on haha. 8.6 Hours is OK, it doesn't need to be fully charged at all times - just enough for a quick recharge in an emergency situation where i can't find a charger or provide another 3-4 hours battery while im kicking it on the train for 6 hours.
I couldn't get the Astro 3 anyway - even if i was looking for a 4-5 hour AC charge.
Looking forward to testing this badboy out!

Portable Battery Chargers

So now that samsung decided to remove the battery, it would only make sense to have a portable battery pack handy.
A friend of mine let me borrow his RAVPower 15,000mAh power pack and i have been testing it on my S4 to see how well it works, so far i am impressed with it, but i've only charged the phone twice, trying to see how many charges i can get out of it. will update this thread and post a better review of it later when i get better impressions of it. i also have an brand new Anker power pack i will be testing later on. primarily interested in charge speed rather than charge cycles. will update this post a bit later with more information and power packs.
link: http://www.amazon.com/gp/product/B00MQSMEEE/

I found this article linked in another thread over at Android Central http://www.phonearena.com/news/Doub...honeSuits-snap-on-Flex-Pocket-Charger_id66907 and this is a nice pocketable charger that doesn't require you to have a cable on hand to charge.
Here is PhoneSuits page http://www.phonesuit.com/phonesuit-...-smartphones?gclid=CJ35qJvdk8QCFRMatAod43cAAg and its listed at $49.95.

that's quite a bit of money for only 2600mAh, guess it's small so that is a plus, but if you want something that can charge several phones with one charge i would go with something like this:
http://www.amazon.com/gp/product/B00NWEB49W/
it even doubles up as an actual wall charger.
smaller than a pack of cigarettes and a bit cheaper than that 2600mAh power pack.

I have this one. It's 10,000 mah, which is pretty good for the price.
http://www.amazon.com/TechMatte®-10...UTF8&qid=1426265278&sr=1-3&keywords=powerbank
It takes about two hours to charge, and then to charge my dead s5 takes about 1 hr and 45 minutes.

I have a Samsung one with 10000mAh and it is pretty good. With a 2000-3000mAh you are not even going to charge the phone up once, so pretty much useless.

I have been using Anker 2nd gen Astro2 for a year now , looks good with plenty of juice , and as per manufacture specs it can push out 3 Amps , 3 Amps is useless on my S4 but it should be perfect for S6.

forget finding a "fast charge" on portable chargers. highly unlikely you will find one. maybe in the future when someone figures out and implement some kind of voltage step-up regulator as it's a limitation right now since to get fast charge to work you need 9 Volt output and current portable chargers can only output @ 5 volts. it's basically a limitation on the internal li-ion batteries, they can only output 4-5V.
your best bet is to get something like the Anker 16,000mAh for high capacity and pretty fast charging, it can output 5V at 2.1A, it will charge most phones (Galaxy S4, S5) in about 1 and 1/2 hours from about 8% battery left on the phone. you might only shave off only 15-20 minutes using a samsung wall fast charger, so it's really not a whole lot difference..
Anker 16,000mAh 2nd gen:
http://www.amazon.com/gp/product/B00N2T7U90/
it will charge an S4 or S5 roughly 5 times with a single charge.

never looked how long exactly it takes, but i will do that when i get my edge.
it's using standard lithium cells from samsung/lg.

Anyone still using note 5 with ORIGINAL BATTERY?

If any of you are still using the note 5 with samsung original battery (never replaced the battery)
Kindly help to measure the mAh
I bought a few after market batteries, i can never reach near 3000 mah on this phone with USB multitester
The reading on the USB multi tester showing max around 2300 mah.... (from 0% - 100%)

how to measure

Thanks for replying. I purchased from Amazon a very inexpensive tool called "usb multi tester" it can test like the amp being charged to the battery of the phone etc... it is straight forward setup. Costs like $9. It shows the voltage of the usb cable. Amp and capacity when the battery is fully charged.

Replacement batteries are poorly made and I consider them as a fire or explosion risk. If a battery fails I get another device. Phones are not built to be repaired.

Thanks for replying. I've bought many fake batteries for my note 5 (though they look exactly the same to the original one) to test and also have bought a few from trusted sources.
But none of these batteries could be charged up to 3000 mAh via usb multi tester to measure the amp being charged to the battery.
