? 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 charge from inverter. Would a portable 400 Watt inverter plugged into Cig Lighter in truck be OK? I hope eventually to get solar with adequate inverter for TC.Does this affect charging time?
Any good discussions on line?
Thanks

    Where did this come from, I wonder.

    Seems to be your imagination at play, again. Ebike in RV = likely a camping situation. There hasn't been any discussion of this, or any comments made by me.

    Now, stating that on a camping "a generator is a really handy accessory" would be an overlooking indeed. It's handy when you a) have no shore power, b) not enough energy storage for the trip, c) no solar big enough to replenish your energy use. Used to be a common picture 15-20 years ago, yes.

    An off-grid scenario was stated by the OP. Duration of trip and related energy storage is unknown. Being a TC, it will be difficult to keep a big bank without expense of LiPo. Carrying generator in TC would be an added inconvenience - maybe, if stored outside, don't know. Big solar will be difficult, though 250-300W should be doable.

    A nuclear bike - that's an interesting idea. Will it come with lead-lined shorts?
  • Are you not going to drive your truck for extended periods of time? If so, then a generator. But if you are driving your truck daily or almost daily, then just put the inverter directly on the batteries. I'd bypass the cig lighter.. but i guess you could start with cig lighter and see if you blow the fuse first.
    Seems to be the logical solution. Your daily drive will recharge the battery is no time. It would be almost like free electricity.

    Nothing lives within 50 miles and that, is mighty clean.

    this fall so I put your question to the manufacture, hopefully they'll get back to me. looks like a cool way to get around.
