    So until now we've managed without an inverter as all the devices we need can be run off 12v (ipad, phones etc) Now though we may need to charge an e-bike and i can only see an inverter being the solution.

    I was thinking a 300w true sinewave device of a good brand like Sterling as the e-bike's battery charger is 42v at 2.0 amps so this would be plenty, right ? I assume that cheaper devices will chew through more leccy to give me the required output.

    Any thoughts ?

    A 150W would be more than adequate. You don't need a pure sine wave.

    Just what I use.

    The only problem being that our pair of ebikes if fully discharged take a significant lump out of our single 110Ah. We have 100W solar. We just about cope as long as good sunshine.

    But we don't drain them both every day.

    Pure sinewave is a good guarantee that you can plug anything into it. My ASUS tablet does not have a 12V solution for a proper charge because it needs 15V off the mains charger.

    We were advised to get a pure sine wave inverter for our electric bikes by someone in the trade who we trust .... is this any good?

    Thanks for the feedback on that and I wondered how much they would take out of the battery, hum I feel the need for some solar:Laughing:

    In case anyone is wondering?
    The original pm never arrived but the others mentioned here were all received and replied to. Neill has bought the 350 watt pure sine Sterling subject to inspection etc.
    A true bargain :thumb:

    Sticking with the OP's post on an inverter for charging bike batteries, does it have to be a pure sine wave inverter, or will a modified sine wave inverter do the job, without damaging the Li-ion batteries?

    Cheers,

    Jock.

    I often charge my Makita 18 volt LXT batteries via my 1800 watt quasi sine Sterling. No problems

    Sounds like it's not really required.

    Am I correct in assuming that as the batteries are being charged by a transformer then the input quality is less sensitive ?

    I believe that to be the case.
    I Charge my wife`s mob scooter from an inverter running the scooter battery charger, when the campervan engine is running.
