    Thanks, but it's not worth it. The inverter I have is more than adequate for almost everything I need, apart from charging two bike batteries at once. On the rare occasions that I need to charge them on the road, one at a time isn't all that inconvenient.

    So how long does it take to charge your all batteries while you're driving then?

    2000 watt inverter was already installed when we purchased MH. It is wired up to three house type electric wall sockets, one in garage, where ebikes are kept. the other two within hab area. A handy addition, certainly not overkill.

    How long it takes to charge a battery depends on the size of the battery, its current state of charge, and the power of the charger. So that's a question that can't have a definitive answer.

    The best bet is to charge little and often, charging from flat takes hours.

    Fair enough, my understanding is that leisure batteries do well on little and often but lithium batteries don't - what about electric bike batteries?

    2000w against 150w, get real, very much overkill

    While on the subject on inverters anyone know a cigar charger one that's nice and quiet? - I've got a 300W from Halfords and it sounds like a hairdryer.

    As neither of us know what the original installer was doing/using at initial installation of the setup I now have, your use of word "overkill" is just that, your opinion.

    With me having used system for various uses, although not that often, I'm glad it is there.

    I forgot to add, when I am charging ebike battery, I am charging two, off, batteries, one for each bike, of course.
