Bummed that I bought the 1,000 mAh pack earlier. Curse you, Woot! This would have been a much better choice.

How do you recharge this thing?

You'll need 2 of these so you can recharge the first one when it goes flat. Oh... maybe better get 3 in case the second one goes too.

WIth a plug!

You use a USB to charge it back up. A review on Amazon states it charges using a usb cord. It has just one review, but other uNu products get excellent reviews too. Looks like a good deal. I am in for one, to throw in my case when I am traveling.

I'm not seeing where it's specified, but since it ships to all 50, I'm going to guess it's NOT a lithium battery. NiMH? NiCAD? Tiny hamsters on a wheel?

It specifically mentions Ipads, then says any USB item. Cant tell from the pic what type of USB plug, is it a mini? anyone know? or is this just for Ipads?

Seems like it would take a long time to recharge to 5000mah from a usb port. Most are pretty current limited.

i have a duracell one like this. however i think it is only like 1200mah or 1500mah but the output is very slow on it so it doesn't charge my phone, it just slows down how fast the battery drains. that being said, the output A rating on this is twice the duracell, and higher than my wall charger A output so i am debating snagging one. they are great to have in a backpack or car or anywhere else just in case. i carry my duracell one around school all day cause sometimes i get stuck there and it is a life saver

Has anyone tested these for true capacity?

I've bought a couple 5000mAh batteries from others and they seem to come up to around 3800. I'm guessing they take the capacity of the Li-Ion batteries at 3.7v and use that as the final tally without considering the loss when boosting to 5v.

BTW, the way I do my test is that the rating (5000) and divide by 20 (20 hour rate). I then pull that amount from the battery until death. I have a device that runs numbers that tells me the true mAh consumed during that period.

The way these normally work is that it comes with the USB cord to charge the battery pack and you have to provide the USB cord to charge your device! I dont have this exact one but I do have a few of the battery packs like this and they are life savers!!!

I've used this to keep my phone and my wife's going for hours while we're in poor coverage areas and they are just blasting away trying to keep a signal. It's fairly light, so I can plug my Android phone into it and just keep them both in my pants pocket on my cargo pants and not even worry about it. I keep it plugged into the USB port in the center console of my car so it's always fully charged and ready to roll. Love this thing, wish I'd bought another for my wife!
