Travelling with 240V?

Well, the computer is easy, Mate! Charge it from the vehicle cigarette lighter plug as you go along.

I leave my ute at a homestead and go off on the quadbike for a week at a time.

I get about two and a half hours with an external aerial, updating websites. Next day, I put the laptop in my backpack when I go riding and charge it from the bike.

Suggest you look into whether you can charge the wheelchair from an auxiliary battery or else run an inverter.

If your wheelchair has a 12 volt battery then I would suggest that you fit an Anderson plug on a small lead to the wheelchair so that it can be accessed easily, and then fit a lead from the car battery to where you store the wheel chair with another Anderson plug on it.
While travelling you can connect the 2 batteries together and the wheelchair battery will charge as an auxiliary battery does.

Depending on the size of the 240volt battery charger that you have for the wheel chair you could run that via an Inverter while the cars engine is running. It doesn't have to be a pure sinewave Inverter to run the battery chargers.
Most laptops also charge OK with small wattage cheap Inverters also.

Your other option is to have a solar panel that could be fitted to the roof of your vehicle and wired to the wheelchair and that would charge the battery whenever the sun is shining. Again Anderson Plugs are an easy way to connect the 2.

Good on yer for undertaking such a journey with the wheelchair handicap.

I suggest you purchase a small inverter type generator and a basic battery charger and use those to recharge the wheelchair - then you can go anywhere you choose.

Do not be mislead by the eternal "Explore Oz Purists" on this forum who insist that "only the best will do" and you must have a Honda and a Ctek battery charger - that's rubbish.

Check e-bay and take note of other replies to this thread but, I suggest, $400 for the gen and $100 for the charger should see you right :)

Leah,

do you know what the battery storage capacity is on the wheel chair? If it's a series of smaller (or even a single large one) Deep-Cycle batteries, then they will probably be twelve or 24 volt system and you may be able to charge them directly from the vehicle whilst it is running. This would only involve the purchase of a suitable dc-dc charger and some decent gauge wire and a method of connecting.

I'd do the easy stuff first (research that is) before going out and spending your hard earned on something that will only add a further degree of difficulty (like a gennie).

Have you approached the wheel chair manufacturer to see if they have any 12 V DC charging options for you.

Cheers Mick

Thank you very much for the helpful answers, we are all for keeping it as simple & easy to use as possible. The chairs battery is a 24v system. Contacting the chair manufacturer is a great idea, will try that tomorrow.

Regarding a generator, I was under the impression they were too noisy for free camp grounds?

Other than what was said above you might want to give Jol Flemming at at Direct 4wd a call....... Jol is confined to a wheelchair and he does a lot of remote camping and travelling.
