battery charger power requirements.

Can someone look at their charger and tell me the power requirements, in watts or amps.  I will be using solar to charge it and need to make sure my inverter is big enough.

From my RadRhino 750W EU (2019) charger the input is 120W (100-240 VAC 50/60 Hz). Output 48V / 2 A.

Perfect, that tells me my standard 400 watt inverter has enough power to operate the charger.  I do appreciate your response...thank you.

Some people who have attempted to use cheap "switcher" type Li-ion chargers like these with non-pure sine wave inverters have experienced a number of problems, up to and including fires.
You should be fine though with a high quality true pure sine inverter of sufficient capacity but even a modified sine type might be a crap shoot.
