Was checking out the listing on Walmart and ran into this review. I don't know anything about the inner workings of battery packs, but this is enough to deter me from a purchase.

i think getting less than the rated capacity after you step up to 5 volts is a given. all in all i can't account for this reviewer's huge feeling of disappointment.

Could you explain the step up to 5 volts, and in the end, the advertised capacity isn't 49800mAh, right?

it's better to express capacity in watt hours - the watt hours are the same at 3.7 volts as 5 volts. you can calculate the watt hours here - and you'd assume 3.7 volts.

advertised capacity is what's written on the battery packs - not what you'd get at some nominal voltage - that's how they all do it.

I think there was a typo. The watt hours are not the same. Watt hours takes the ah multiplied by the voltage.

This is why a 10ah 12v battery is so much powerful than a 10000mah 3.7v battery.
