Charging battery when away from home

[jann71]

Just had my first 3 day adventure sleeping in my van with the bike. I would usually stay in a hotel so that I can charge the bike battery but this is cheaper

Looks like few possible options but I know nothing about watts and amps.

Has anyone charged a battery with electric hookup on a campsite?

Or would something like this have enough juice to charge the battery?

12 hour spoons stops?
Seems that the experts on here reckon that device you linked to jann won't work, and in any case rather reminds me of the old jokes about the pocket tv that ran off a car battery.
Not being funny, but do you have to use an electric bike for these van-based adventures @jann71
Any way you can use a bike with appropriate gearing/appropriate routes?

The Currys PC World device has a three pin AC outlet.

It has about 1.5kg of lithium batteries.

Plugging the ebike charger into the AC outlet should work, but the fully charged device might not do a lot more than half charge the ebike battery.

A campsite hook up would be much better, provided your camper has a three pin AC outlet.

The same product is in Argos where it has a little more detail about battery capacity which is 155Wh

This will explain why that is important

with a 250Wh e-bike battery you might get to charge your bike battery from flat to 60% at best. However e-bike batteries can be a lot higher capacity than that so depending what you have on your bike it could be a lot less than 60%.

Thank you. I was thinking about the powerpack originally just to run a wee heater.

I have a 400 and 500Wh so I was fine for first 2 days.

Thanks for your replies. Maybe a combination of powerpack and inverter would give me enough charge for 3rd day or less miles on day 1 and 2 if I'm not on campsite with electric hookup.

Mm
Thanks for the reply - clearly a conscious choice.
Will follow the thread with interest, the hoops you are going to be jumping through for the fun.

And buy an ebike that still rides well when the assistance is switched off. A lot of supposedly well respected bikes - Cough, Woosh, Cough - become leaden lumps when your legs have to do all the work, but others feel like perfectly decent, albeit a little heavy, regular bicycles.
