Which Battery stick has more juice?

[Norval]

While traveling I use one of these battery sticks to charge my phone. The question is, both look very similar in size, but they a bit different in their specs. Which one has more juice ?[emoji848]

If their specs are honest -- or equally dishonest -- they are about the same. They're both probably using single-cell Lithium batteries rated at 3.7VDC and they both claim 2200 mAh, which is 2.2 amp hours. The battery with the square corners claims higher input amperage, which means it might charge faster from a 5VDC charger, but that doesn't affect output.

Great! Thanks petej!
As you mentioned, this are made in china, and, wouldn't be surprise if they are not exactly what they claim....
