G’day Carlin
A steer away from just generators and AVR ones too. The AVR May hold the voltage at/near the right voltage but it may be way out of phase and no where near 50 cycles / sec. Many modern items use switch mode power supplies which are made to operate at 50hertz. If the frequency isn’t right for some items the switch mode inputs either don’t know what to do with it and they get hot and burn inside or simply won’t start operating
With 12v to 240v inverters similar happens.
I have one Laptop which runs on 12v inverter Non Sinewave, and one which will run on the Non sine wave but gets a bit too warm. I imagine the various generators are similar. Wave forms different though.

My Honda E20i will run in Ecomode as many do, and it then only makes enough power to cover the load.
It will run a 9” angle grinder and I have used it to weld with an efficient inverter stick welder with small rods in emergency situations.

If using any generator for battery charging don’t use the 12v charge outlet. They are next to useless and require the generator to run at full speed. Using a 240v battery charger with Genny on Eco, means it will run much slower and efficiently and quieter while running the battery charger at it’s full output. Far more efficient this way.
Cheers

   Ive had my eye on these one -

Wal:
You do pay for what you get. Personal choice would be Honda or Yamaha which are proven generators. Though you pay more you get reliabilty.

If I was going to use it heaps I’d go Honda / Yamaha. But am tempted by them tradetools ones.

OldMucks:
Couple of mates have generators one has a Yamaha 2.4 kva about 4 months old and it started to play up he had a look inside and reckons its the worst assembled machine he has seen - paint missing - uncleaned or painted welds - the problem was corrosion on some of the terminals that he is trying to get fixed under warranty.
Reckons next time he get a cheap one.
The other bloke has a property and bought a Grudge 3.0 kva at a farm fest gets thrown into ute when he needs it went for 3 yrs and blew a voltage regulator $60 for a new one obout 5 yrs ago still going strong.
Reckons next one will be another one.
I tend to agree with both of them - buy cheap and throw it out when it plays up.
