Would an induction hob be any good for in cab cooking instead of a gas one?
A hobs max watts is 2200w (ours is anyway), but would an inverter (and the trucks batteries) manage it…?
Just thinking of possible alternatives to the gas… 
Firstly I`m no electrician so if anyone wants to correct me, go ahead.
Look at this link:
ebay.co.uk/itm/3000W-6000W-p … SwcLxYIFI1
And note what it says about ratings :
For inductive loads:
If connecting with inductive loads (e.g. Compressor, Pump, old CRT TV, Refrigerator, Ice conditioner, Air conditioner, Relays，Fluorescent lamp, Vacuum cleaner), please choose inverter whose rate power is 3-7 times higher than the load’s rate power. For example, for a 150w refrigerator, please choose a 1000w inverter or higher; for a 800w air conditioner, please choose 2500w inverter or higher.
So if an induction cooker is an inductivie load* you`ll need a, say, 10 kilo-watt inverter. . . .
- It is.
EDIT If you did find a 10kw inverter it could take about double the current of a starter motor. . .
(as I said at the start, anyone can feel free to correct my rough figures)
I think if you’re going down that sort of instant power needs then a portable generator, if you can find one small enough to fit in the passenger footwell, would be the way to go.
We have an induction hob at home and can see the want to use one in a truck with just the safety aspect alone as they dont get hot as such and only transfer the heat of a pans contents back to the plate and cool back down quickly. However, as Franglais points out, a very large inverter would be needed to power one. Is there such a thing as a portable induction hob??

Yes, like this :-
Lidl. or Aldi, have just been selling some too. 2000w at 240v. We have one at home, like you say it’s great the way they work with so little residual heat on the actual hob. Be interesting to know what size of inverter would actually power it.
You might want to keep the engine running when you’re using your hob…

Absolutely. Who wants to carry those volatile and dangerous gas canisters, if you can carry save and convenient petrol instead…
I tried a halogen oven in my truck, i plugged it in to my 2200 watt inverter.
It worked perfectly.
However, it takes up a bit of space.
Great fish pie though.

Oops edited thanks.

I remember Lidl’s returns warehouse from…
Many years ago at South Elmsall.
It was rammed with all the ‘cheap fall to bits in a week crap’ that had been sent out a week earlier.
If you’re determined to blow yourself up/set fire to the truck/spontaneously combust then, pay proper money and get a decent one.
Why would you go to the hassle and expense of one of these when you can use the tried and tested gas one for a tenner?
A.
I’m not sure if my maths is correct (it’s a very long time since I left school) but if Power (watts) = voltage x current, then surely to supply 2000 watts requires 2000(w) / 24(v) = 83 amps? When we had an induction cooker installed at home we had to have an increased capacity cable installed (think it was 100amp?) in order to handle it, and the cable was extremely large. Would a battery system be able to handle that for the amount of time required when cooking?
