? Charging Electric Bike Battery
I'm short on Electrical know how and just got E bike with Samsung 36 volt ,14,25 Ah battery. Came with 110V AC charger. Normally takes 4-5 hrs to recharge per their info. When off grid I want to char...

Insufficient data. Check the INPUT watts or amps for your particular charger. They are all different proprietary chargers for each bike and each battery.
If you want us to guess...
Ebike batteries are easier to understand in watt-hours, because they are all of different voltage.
14.25 @36V = 513 WH, and it's not supposed to charge over 80-90% or to discharge below (don't remember, 20% or something). So, about 350WH will be be charged, 5 hours run makes it 70W power, i.e. 6A @12V. Make it 7A with inverter losses. Looks like within the limits of cig lighter socket, though I would rather connect inverter directly to coach battery.
7A @12V drawn for 5 hours will deplete your coach battery by 35 AH or more.
