12 volt chargers for all types of electric bikes
Its in our camping magazine this month

Thanks, I’ve had a look but well outwith what I’d pay for how often we would use it.

will stick to using inverter while travelling.

Brilliant .. thanks!

The reality is we’ll not be getting an inverter so this looks like a great alternative. I’ve been looking for another option for a while

looks good, but a bit more expensive then Bosch's own Travel Charger (now discontinued).
hope my maths is right but this is what it looks like...
output is 2A, so to charge an 11.6AH battery means 6hrs use.
input is 10A, so 6hrs use means taking 60AH from your battery.

I'll stick to my Inverter thanks, can also use it for other things.
Plugging into a 12 volt system to charge up a 36v appliance needs thicker cables behind your socket. Watch out for warm wiring.

At those prices I'd prefer a small inverter so I can also do my laptop, and other small electrical needs even if the inverter creates some minor inefficiencies.

I think you're better off with a good quality inverter, mains power is everywhere and used for everything. Why buy expensive dedicated chargers for everything? You get a mains one free with every gadget

Oh, 1 exception - phone chargers

Your maths is spot-on, but your physics is shaky.

Amp-hours is used as general 'energy' unit because everything in a motorhome is 12V, and it's easy to measure and calculate. You should really say 'amp-hours at 12volts', but of course that gets tedious. Comparing with other voltages needs further calculation.

The 11.6Ah battery has a voltage of 36V. The energy stored is 11.6 x 36 = 418 watt-hours, usually quoted as .418kWh.

Compared with a 12V motorhome battery, that's 418/12 = 34.8 amp-hours, which is what it would take out of your 12V leisure battery, plus about 10% for inefficiencies. The '10A input' is probably a sudden inrush current when you first connect it. The current drops to a steady value very rapidly.

my physics has now improved, thanks...
