I am thinking of buying a 48 volt 25 AMP battery charger that has a standard 110 plug. What is going to happen when I plug it in to a standard 15 AMP household outlet? Will it only draw as many AMPs as it can ie 15 or will it trip my breaker every time?

[QUOTE=DrkAngel;9496]48 volt 25 AMP charger output requires about 110 volt 11 amp input.  
Figure 20% loss due to conversion inefficiency = 12-13 amps from 110 volt.  
15 amp outlet is fine.[/QUOTE]  
Thank you

Input: 100-240V ~50/60Hz 12.5/7.5A

Output: 48V-25A 25.0A@100~

can someone say that to me in English please? what are Hertz I thought they rent cars, jk and please spare me the Wikipeida answer talk to me like I’m six years old

so here’s what I bought as seen in the eBay pictures, man it works great it charges my four 55 Ah batteries in less than 2 hours, I double checked and my garage EFI outlet is 20 amps saweeet, I was also able to mount it right where the oil cooler went originally on the bike so right in front behind the front wheel/fender

Hertz or Hz is the SI unit of frequency
