I can see some of you shaking your heads, with a wry smile at this news.

I ordered a 1000w PSW inverter from AliExpress to charge some occasional devices (not a fridge!).
This was a month ago.

Tracked the item yesterday to find that the seller has decided not to supply. No reason given.

I am now running out of time to get such things sorted before our summer holiday and so have bought the WaveInverter recommended by a couple of people on this thread off TradeMe.

Maybe I'll have to now buy a Samsung fridge to give it something to do!!

You are not the only one to have the occasional hiccup with Aliexpress Mark. I have had a couple of "no shows" and one item completely different to that ordered. Fortunately the dispute process appears fairly robust. I did lose one $40.00 battle though - my fault in the end.
Your WaveInverter model will perform perfectly.

Oh man that sucks. Maybe I have been lucky, years of dealings and much money spent with never a problem worse than waiting almost four weeks once around Chinese new year.

But, I do tend towards suppliers with good feedback, selling products with good feedback, especially where that feedback is from happy customers in New Zealand, something I often forget to check on trademe which may have contributed to my increasingly bad opinion of that particular site

Haha! By the time I've tracked down what I want (and found the cheapest version - landed in NZ) I've run out of puff and don't ever think to check the store feedback. Maybe I should, now.

From the user guide of the Wave Inverter device, which arrived yesterday:
"Some electrical equipment is not compatible with power inverters. Typically some types of devices that incorporate a rechargeable battery eg portable lights, shavers, or the battery chargers of certain power tools ...."

Well, that's a bit of a turn up :o

I intend to use the inverter for charging: my netbook computer, a Bluetooth speaker and a Ryobi One 18V battery pack.

Is the warning just a case of the supplier/manufacturer covering their backside - or do I really have a problem?

Hi Mark. Which inverter have you got ? In my experience non pure sine-wave inverters can have problems with certain devices. Paul

As long as you have a pure sine wave inverter of sufficient wattage you will be fine, they are designed to be indistinguishable for 230v mains power as far as the appliance is concerned.

This is the one I've got.
https://waveinverter.co.nz/shop/power-inverter/300w/

Advertised as a PSW but why then would they put this warning in their Owner's Manual?

I have assumed it is just backside-covering and have installed it anyway.
