I know I could have asked you for advice via a pm Neal, but, as you seem to be an expert on these things, I wondered if you’ve got any thoughts on this as it might be helpful to other members as well as me

I know very little about microwaves, I just used to have a couple of trucks fitted with 24 volt models. I would always go for the 24 volt over the domestic and inverter arrangement as I read on here about people using them who have to run the engine every time they use it, or at least every so often. With the 24 volt models I had I never ran the engine and could use them for well over an hours total heating time without battery problems.
Most of the 24 volt ovens have a power consumption of 30 - 40 amps but they say they say they have modified this one to only draw 5 amps, if it works that will be very kind to the batteries.

You cannot reduce the amperage of an electrical device without also changing either the voltage or the wattage since Volts= Amps x Watts.

Yeah I know, they have changed the wattage. That’s a domestic oven they say they have modified to reduce the watts, output wattage which must also reduce input wattage? They say this has in turn reduced the amps to around 4.5.
They should really makes this electrical carry on a lot more simpler. Amps, volts , watts etc it all annoys me.
Thanks Neal (and harry). Will now look out for a review or two to see if it’s worth buying!
buy a 2000 amp inverter for about £120 and a domestic microwave for about £40 job done just tidy wireing to do which youd have to do with a truck oven

am considering this route myself which inverter should i look for? (not really savvy when it comes to these things)

Wow, you just suggested modyfying the laws of physics because “…It really annoys me” 
Good luck with that!!!

I think he means 2000 watt 
Hmm the 500w 24v Microwave in a Scanny I was driving was drawing enough current for the truck to decide to lift the revs to compensate for the current required.

And I thought Watt invented the steam engine

Nice one, bookmarked, Thanks.

500W microwave won’t do [zb]. It’ll take an hour just to warm up a cuppa.

Both the 500 watt 24V microwaves I had fitted in trucks worked perfectly by adding about a minute onto each part of the cooking times for a 700 watt oven on the instructions for the item. If it said heat for 3 minutes, stir then heat for 2.5 minutes, I found 4 minutes then 3.5 did the job.

Well obviously it didn’t take an hour, but you get the idea… I used to have a 500 watter in a place I used to rent years ago and it was as slow as Post Office queue at 1pm. I grant you, I’d rather have a 500 watt micro in a truck than nothing at all, but just saying… I’m struggling to figure out how they’ve managed to drop the ampage so much without affecting it, or was it not a 500 watter to begin with? 
Yes, basically it will take 1.4 times as long to heat an item by the same amount using a 500w oven compared to using a 700w oven (7/5 times as long).

It wasn’t 500W to begin with, they dropped it to just over 500 and that reduced it’s draw.
