It may have a 5000mah battery, but at what voltage?

I've found that many battery packs boast high capacities but if it's only houses a 3.6v cell lots will be wasted during the step-up to 5.0v and won't supply 500mA.

Who's for ripping theirs open so we can find out Very Happy

not me ;) though i can say that it doesn't get hot (like my emergency charger that runs off 2 x 1.5v AA batteries) so i would assume if it IS being stepped up from a lower voltage then it may not be by very much.

Ah…the truth be known!

It says it can deliver 5V at up to 950mA, but I bet it wouldn’t last long and would get nice and toasty (ideal hand warmer).

You want a nice 7.2v (or larger) cell, then it could maintain a nice stable 5V and a good current for much longer Very Happy

Problem is it would also cost much more Sad
