Cheap(ish) PSW inverters

I had a 12v microwave but it didn’t have a grill or an oven. I only use the microwave bit not the oven underway of course.
12v kettles are useless.

Edit I’d forgotten the microwave was useless too because it was a 30 ft cable run from the batteries and I would have needed to upgrade the cable due to current induced heat losses (I didn’t fit it) The inverter is 2m.

I agree that microwaves draw too much current, and 12v kettles are next to useless. I use gas to boil the kettle, and I don't need a microwave to cook, though I admit it would be a nice thing to have.
 
I think those figures a a bit optimistic, for instance, a Victron 1200w inverter will draw 8w @12v with zero load. I'd still advise you to turn the 12v supply off when not in use, as simple on/off battery isolator will suffice.

I hear what you are saying. And will plan an isolater into the system. I am also putting a fuse into the positive from the battery to inverter. I was thinking a 175A as the inverter offers, allegedly, a 2000w surge (although I can never see me using it). The figures I have quoted are measured using a decent clamp meter that has always given me accurate measurements. I'll retest tomorrow, just in case, but I was particularly happy to see the very low figure when turned off. This does make sense, as all that is running is an LED light in the remote control panel itself.
 
Interesting to hear to many positive comments about cheap inverters. This is in contrast to when I last asked about this topic. Maybe they have upped their game? It would be quite disappointing to spend hundreds on an inverter to find that it doesn't actually deliver the goods (that is, not true sine wave or unable to deliver the claimed output),

I'm looking into using the inverter to allow a partially electric galley. This is becoming increasingly popular as technology improves. An induction hob creates far less wasted heat and is safer than using gas, and for the relatively low amount of total daily run time required it does appear to be viable for cruisers in sunny climes, especially if you retain gas as a backup for those day when you do not have surplus solar power. Unfortunately induction hobs need true sine wave to operate.

I dont think its so much the chinese have upped their game its just more of us have bought & use these items daily and theres very little wrong with them. It happened with the russian copy heaters then again with the chinese copy heaters and so it goes. Me - i love a bargain and at the price point these things are sold for i couldn't give a toss if i dont get more than a couple of years out of them.

Throw it away and buy another. I've spent 25 years owning, using & repairing expensive name-brand plant and tools and they're (now) just as crap as the cheap chinese stuff in terms of longevity, fit and finish. So if the things gonna blow up anyway after two to three years i'd much rather spend £200 instead of £1200 plus all the associated expensive main dealer pricing for repairs and just buy another chinese knock off.

I don’t have gas which has its challenges - gas is very good at boiling water. Except in very cold weather when it is curseworthy.

And microwaves are handy, especially as when you have no gas you have to have an electric oven, so it might as well be oven/microwave/grill combo taking no extra space.

Propane works fine in cold weather.
