External backup battery

I'm looking for a backup battery. Has anyone come across any that have enough juice to put a good charge on the nook? I know those little 400mah batteries can charge the nook but how long will 400mah last? I'm looking for something that can give it a 50%+ charge

This what you are looking for? That would get you about 1.5 charges.
This would give you about 1 charge.

The Zagg one would be perfect but its $100! I dont want to spend over $50 guess I should have said that.
I will look into the other one you posted thanks
EDIT: The energizer one looks great!! I am probably going to order one. Thanks a lot!

I didn't notice an amp output on the energizer. NC is looking for 1900 mA for proper charging. That first gizmo is dead perfect but 100 beans is a bit outside my budget too. I have a 4400 mah battery that does 1000 mA output- i wonder if that would add a few hours to my NC? I take very long flights often.

If I remember right The stock nook color charger is rated at 1.9A which is 1950mah. The energizer website lists the battery linked above as 1750mah which should work great.

Check out Brunton Chargers:

I went with this unit, http://www.amazon.com/gp/product/B0038VQET4/ref=oss_product
It's under $40 and provides a full charge.

What is the recommended way to test the time-to-charge? There are two issues that I see in capturing this data.
1) You really shouldn't run the thing dry - I mean it won't even boot with the power adapter plugged in until it has a little juice in the battery. I suppose youl could to drain it to 25% then charge from there. Then add 25% to whatever your time-to-full is?
2) how can you tell how long this thing takes to charge if you're asleep. Is there a log file which gets updated with charging events? Or some specific app for such things?

A little big but if you want to keep your mobile devices running for a long time try this:
http://www.amazon.com/gp/product/B003ZBZ64Q/ref=oss_product
It charges my NC and G2 3 times each and change. Especially useful when using the wireless tethering on the G2 to keep the NC online.

I've been running my NC entirely from a Tekkeon MyPower MP3450 with the MP3450-10 add-on pack for two full days of heavy usage (probably around 18 hours or so of actual use) and the MyPower is only drained down half-way while keeping the NC topped off at 100%. I'll be back with an update in another couple of days when I expect it to be empty.
Edit: Yep, I got four days of heavy usage (probably equivalent to four full recharges of the NC) from the Tekkeon pack. I bought it to keep my laptop running on long flights, but it's nice to know I'll be able to read if the power goes out for a few days.

Will using a standard usb cable with these backup batteries still only charge at .5A? If I use the stock nc cable on the energizer battery linked above will it damage the battery?

Have you looked at Monoprice? They have battery backups. I haven't personally ordered one of these (yet...need one for my evo) but I've ordered lots of stuff from them and everything has worked very well.

That's a decent price. Have you had much of a chance to test the unit?

With the NC's built-in battery rated at 4000 mAh, this battery should be able to completely recharge an NC. Or give you an additional ~8+ power-on hours.

I have a version of one of those, works fine except it's hard to keep in place. If you get one, also get a M-F cable as well.

I went with THIS deal to get THIS battery pack for free. Not expecting much, but will post back when I have some results.

Im finding it near impossible to find a USB 2.0 Micro-A male to Micro-AB female cord. Especially in a shorter length.

I have up trying to find a cable and bought http://www.amazon.com/gp/product/B003NTYYXY. I will update my findings when I get it.

When I bought mine, I just Googled "buy micro usb extension." I just did it again and found this in seconds...
http://www.usbfirewire.com/Parts/rr-mcb-ext-xxg.html
A Micro B male fits both Micro A and B female, which is why nobody bothers selling Micro A male cables... It would be less compatible with nothing to gain.

Thanks..I am surprised Monoprice doesnt carry it. Anywho, after shipping + cost of that cable + 2 x 2800 mAh, it was cheaper to buy the one from Amazon.

Defy+ external battery/power bank/portable charger

this has been real hell finding information about whether this http://www.ebay.com/itm/Powerocks-p...y_Chargers&hash=item3cc55ca8b0#ht_4645wt_1163 is compatible with my Motorola defy+ (note custom roms, Switching from time to time, Currently on WIUI ICS) and other information such as how long does it last and etc.
has anybody used this?
is it worth the money and how does it translate to battery % on my defy+.
any other feedback?
and maybe other recommendations (with that price region)
and is there a thing like this that uses AA batteries, if so, how many will it take to charge my Defy+
thanks ahead
EDIT:
what's the proper name for that thingy? because this thing has wayyyy too many names,
power bank, external battery, portable charger, portable battery, extra battery. and many many many more!!! this is why it's complete hell finding information.
what's the real and most proper name for it?

Just a single word 'AVOID'

i don't usually like to be disrespectful, but.
you sir, have convinced me with your long list of arguments and good points of reason to support your advice.
could you please explain, why?

Ok. Here it goes.
I have used these chargers long back, I think around a year back. It barely charges 15% of your mobile battery (I was using a Samsung Galaxy Apollo at that time which had a 1500mah battery) with a single AA cell which I think is totally not worth.
I hope this is enough for you to get a fair idea

so, you're saying that the Portable chargers that use AA batteries are bad, or are you saying all these portable chargers are bad and charge too little?
if you're saying that all the portable chargers are bad and charge too little, then i would have to say that it depends on how much mAh the charger can hold.
say i get the 2600 mAh charger to charge my Defy+ (think around 1700 mAh) when it's completely out, i think that i will charge fully at least once (say around 1000 mAh at MOST! is lost because of the charging procedure)

i'm only talking about the AA battery based chargers. I don't have any idea about other powerpacks as I've never used it.

1 AA battery for 225 mAh!?!?!?!? that's awesome!!! would be great for camping trips, you get like 12 AA batteries (or more, depends on how long you plan to be away from charging your phone normally) and you can even play in the evening or even watch porn if you got Data signal!
i'm still probably going for the normal one, and maybe i'll get an extra charger that uses AA batteries in-case i go camping somewhere.
can people please give feedback on whether it's good enough? why are there only 2 posters?

I think that it works just seen a duracell one in a store near me wich holds 4 AA batts, i think on buying it and fillit with some 4 NiMh AA acumulators rated at 2700 mAh each, just think about it thats 10800 mAh in a portable charge, that will charge my Defy battery at least 5 times even with an extra burning that the charge does.

isn't there a case of voltage involved? (idk, i'm a complete noob in this)
and i need something smaller, something as small as the charger i posted.
i'm just curios to know if it works or not and any other feedback about it.

lol
NiMHs are 1,2V which means, 2700mAh hold 2700mAh * 1,2V= 3,24 Wh which is the same as 11,664 kJ
The Defy battery holds 1500mah at 3,7V --> 5,5 Wh = 19,98 kJ
Taking efficiency in count you might be able to load your Defy with two fully charged NiMHs once, but i`d rather expect that two are not enough.
As for the that eBay-offer: The voltage is given as 5,1V. With 2600mAh that would mean 13,2 Wh. But i rather believe they are stating the capacity at 3,7V for marketing reasons. That would mean 9,62 Wh. That would allow you to recharge about one and a half time.

So someones after advice on portable power when away from the mains?
Ive been using a New trent imp1000 to keep things going, its a li-ion rechargable powerpack with a capacity of 11000mah and it keeps my Defy going for 4 days.
I also have a total of three batterys for my defy, and a universal li-ion external charger, called a cam caddy, although its designed to charge camera batterys from a 5 volt supply it also quite happily charges up the battery for my defy as well.
So for extreme use i can have a battery in use in my phon, plus a spare with me, and back at base ( or just overnight) a battery on charge in the cam caddy.
If im in an area with access to mains i will take the imp1000 and its charger to top up where and when i can.
I also have a universal USB charger with swapable plugs that fit all major power outlets worldwide.
And to top it all off a USB AA battery charger that will ( slowly) charge up 4 AA batterys form a solar panel, or from a USB input ( faster) , or output 5V through the USB out put port.
This little set up has kept me going for 14 days with no access to mains power ( except for a few bits here and there - 20 minutes at a bus station/railway station and so on) , keeping my phone going (defy) a high powered AA cree LED torch, a camera ( via spare battery+cam caaddy) and an mp3 player. the trick is careful battery management - on the defy turn off everything when not in use, except the ability to receive calls and number your batterys for ID, and the same for cameras etc etc.

i think 11000 mAh is a little too much for me, it may be good for camping trips and etc, but i don't think i'm gonna buy something that (probably) big and (probably) expensive. most of the use of the external charger will be when i'm out with friends for a long time, or say after school i spontaneously decide to go out with friends before getting home (unfortunately a 1 hour drive from friends city to mine) so i need an a portable charger so i won't get bored on the way back, my battery lasts a school day, if i go somewhere that is not home after school, it won't last.
about the extra batteries, are those original from motorola? if not, are they as good as the original? are they worth getting?

The batterys are official motorla ones, as i b ought a cheap un official one and that had issues ( wouldnt show the charge level on the defy )
The battery pack is a "new trent imp1000" which costs £30 from amazon.
I also have a dock for the defy in which my phone usualy sits, at the back of this dock is a slot for an extra battery, left overnight this will charge both my Defy ( with battery inside) and the extra battery in the slot, this is plugged into a dektop pc where some of the USB sockets are still powered up ( giving out 5v) even when the desktpop p.c is off

supdealer offers nice portable power bank
as portable external battery/power bank/portable charger, An ebay seller called supdealer sells a nice one. You can have a look.
It may help you. :laugh:

I have that new Trent battery, its perfect almost same size as defy.

Guys,
If you really want true power on the go, buy a YOOBAO power pack, the 11200 mAh one.
It is really a beast and is really charging a defy several times before going empty.

Yes, all iPhone compatible USB-Chargers are compatible to our Defy and other new mobiles.
Why? EN_62684: Common External Power Supply (EPS)
Why would I use Li-ion instead of AA Cells (NiCd,NiMH or NiZn)?
Higher Energy Density!
Another benefit of Li-ion is the discharging charakteristika (sorry for german captions).

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!

External battery pack for G2

Hello,
I m looking for a battery pack which would feet with my new lg g2. I nearly bought an Anker but their custom service told none of their batteries were compatible with the G2.
I found some clues that the Trent power pack ultra do work with it but I cannot find a way to deliver it to France...
Does someone has a valid battery pack which working well with the gorgeous G2 battery? I am not looking for a case because to be able to use it to charge some other stuff like an iPad.
Thanks.

Compatible? It's just a charger, right? It just provides a ready supply of power at a certain voltage, with a max amperage. So I'm sure everything will work. If you want max charging speed, pick a 2A max current model

I saw few comments of users telling that their phone stop charging 3-4 seconds after plugging in the charger. Anker even remove every reference to LG G2 on their website, some battery page mention of "not compatible with G2" cf: Anker 2nd Gen Astro3 12000mAh
It s what made me suspicious, and I have started looking for real feedback on battery pack with G2.
I m guessing g2 with his gorgeous battery have some kind of protection circuit which does not accept low current charger or stuff like that.

Seems odd to me. I've been using my phone with cheap ebay chargers, which admittedly gave me pretty slow charging, but they've always worked. Sorry, I can't be of any help then, maybe someone else knows.

I have a RavPower 10400mAh and it works great with my lg g2. I don't know why Anker doesn't have any chargers that fit with g2 as most of the phones in the market has either a cable like apples' or a unified like most of the other phones.

Just for information, how long does it take to charge your LG G2 with it?

it really differs, I mean, some were absolutely crap, but most of them are able to give atleast 500mA, concidering its a 3000mA battery, that would be 6 hours. In comparison, the stock charger would manage to do it in well under two hours. But charging rate is something I think the manufacturer should provide in the spec sheet.
If you have a Verizon model, you might run into problems as third party chargers have been reported to be very slow.

Look HERE . They have some awesome deals.
30,000MAH is that even possible?

I checked it out. It says
"Battery actual capacity:13800mAh"
Which is still fairly much. It isn't exactly uncommon for chinese manufacturers to exaggurate

they might be accidentally adding an extra zero at the end. HAHAHAHAHA! :laugh:

I sprung for a mophie powerstation XL (it helps I work for a large photo/electronics retailer and got a great discount on it) and am very happy with it. It's a little big and weighs about a pound, but fits in my bag and it can charge my G2 and my N7FHD multiple times. I'm going to Vegas for a week and know the 12,000 mAh battery is plenty to cover my devices and my wife's SGSIII.

I've got an Anker Astro 5600mAh and it charges my G2 perfectly fine. Sure, its at the slower speed, 1A, but a charge is a charge.

Sometimes it cant charge with external charger because of the charger and phones electronic talk together and find some reason why not to charge. This problem is very usual with laptops and laptop chargers. I had this problem once with phone too and the easiest what helped me was to use another microusb cable, the one with only charging ports, not the data ports.

I use the anker 2nd gen 6000mAh and I have always a good charge time

Try the RAVPower external battery pack, I have their 14,000mAh and it can charge two devices at the same time. It did help me out of emergencies many times.

I would still like to know why its not compatible. I've been using the 1st gen anker astro (10,000 mah model) without issue untill it has decided to die hence now looking to replace it.
I also use the Anker 40w wall (also using power QI) charger with my G2 without a problem...

have raikko 5200 MAh, have it for about 3 years (bough it for my old optimus 2x originally) and it still works. I think the capacity is little lower now, but still great results after long time. I can charge approx one and quarter times.

i have 3 diferent external battery packs. (im playing ingress)
My advice ... By a anker of amazon. thay are by far the best chargers and the price is realy good.

I had the same issue when I was going to buy an Anker battery pack as well.
I think I'll probably get a RavPower battery pack. Is it best to use the 2amp slot to charge the LG G2?

Noontec Polo II
I have a Noontec Polo II 5600mAh battery and it charges my phone (D802) perfectly fine. On 2A out it takes 2h10m from 0 to 100% (phone turned on, very very light usage during the charge process)

Note8 Fastest-charging battery packs?

I'm looking for:
From Amazon US site
Charges Note8 via Fast Charging
Has more than one full Note8 charge
Suggestions of ones you've tested? (URLs?)
(Most of the battery packs I have tried do not provide Fast Charging on Note8.)

How big you looking? I have a 28600 anker that has fast charge. They now have a USB C PD bank that should charge faster than reg USB to C. Have heard RAV are good also. Just putting that out so you can have a choice and compare. I do know one thing I got a 5k version for my son non fast charge. I took it on vacation in July invade we needed a smaller charger on the go. Forgot it was in the suitcase. I pulled it out last week and it still had a full charge. So anker seems to know their stuff.

I was looking around 10Ah, else they get too heavy for just me. For when my family travels, 20-40.
What's the URL/model for your 28600? I don't see any with that value on Amazon.com (oh, the 26800 for $83?)

Thee zerolemon external charger ( not the phone case) works well

I have the Samsung Fast Charge 5100 mAh battery Pack w/ USB-C and it's a great little charger. The screen on charge is 1010mA average and the screen off charge is 2356 mA average. I purchased mine for $37. If it's for yourself and not a gift, you can get the damaged packaging one from Amazon Warehouse deals for $25.91. I love the small size of the charger and the build is great. I also purchased this Soft Felt Pouch for the charger.

That's the one I decided to buy. Silver and Navy Blue have "like new" for $20.
The.passthroigh charging was another strong point in its favor.
Thanks to you, and to all who replied!

Yeah it's the $83 one. I got it on sale for like $60. I will say get what you need. I got the big one because it was a disney trip and we all know smartphones drain fast. Needed the power bank to last all day. Whatever you get they are very handy and not reduced to looking for a plug.

This question for everyone. How long does the battery pack hold its charge? A week, month, longer? My main reason is power outages. My last portable would be dead by the time I actually needed it. Would be nice one held juice 2-3 months. Idk if thats possible? I live in the city. We usually have power outage once every few months. Sucks being in the stone age for 0-6 hours. Depending on what caused it and how much damage.

I have an anker 16000 I got a few years ago.. I charge it may be once every 4 to 6months or so when I go for a long travel... It usually shows more than 80 % even at 4 months...

Ok cool thanks I appreciate it. Anker definitely one of the best battery brands out there. Thats impressive charge hold and perfect for me. Will cruise Amazon and look for best portable Ankrer battery pack. Thanks for the suggestion!

That's how my bank is also. Drain is minimal. I dont know about the rav or others. I only have anker. I am sure the more popular brands has the same performance

I have a romoss sense 6+, 20000mah has a usb c in and out, quick charge 3.0 PD3.0. Very affordable as well. I got mine for 15usd

Heavy power consuming apps and constant usage if WhatsApp and Facebook will definitely drain the battery of any smartphone. And power bank is one of the solutions to this thing who are traveling continuously. That's why I'm using Anker 20100mAh power bank, this power bank charge 2 device simultaneously at faster speeds.
