Generally,in the market, mobile power transfer efficiency is about 80%, better can reach more than 90%, and ordinary mobile phone charging conversion efficiency is about 75%, of course some phone conversion rate and even less than 70%.Turn the wastage of the wiring connector is commonly 10%, can be down by 60%, it is very good.So, nominal capacity and the actual capacity of mobile power supply there is normal.
