Mobile battery packs

[Teknikal]

Anyone else using these?

I just bought a new one as there has been plenty of rioting, bad weather and power cuts here in Belfast the last few weeks and I rely a lot on my phone and other USB powered gadgets I'd hate to be stuck without them.

I already had a small 2,500mah one which can fully charge my phone once but I decided that's not enough and bought a 10,000 mah one which has dual USB slots (one at the full 2 amps and one at 1 amp).

Surprised me a little to see the first initial charge has to be about 14 hours but I think it will be a useful thing to have, can't wait to experiment and see how many charges I can get on my various gadgets.
