New Power solution for your equipment~ Portable power bank?

32000mA/hr = 32A/hr, which is meaningless without knowing the voltage. But if the W/hr rating is 118.4W/hr, the A/hr rating is calculated with a supply voltage of 3.7 volts, which is useless for the equipment most of us use. Something is amiss. Maybe the specs of two different power supplies are being compared.

But it's a good example of how the Amp/hour rating is no good by itself, and for what most of us on this group do, should go the way of the V(irtually) U(seless) meter. The Watt/hour spec gives the true capacity of a battery, which explains the current tension.

Who doesn't like P=IE?

Real VU meters had (and sometimes still do have) value when used for their intended purpose.  Unfortunately, they have been improperly used all too often, and the majority of meters labeled VU, do not have the appropriate ballistics to be true VU meters.
