Questions about Maxxtro Mobile Power KV-300 Power Inverter 300W

DE, Schuko socket. We bought an adapter for it, which is always plugged in.

Good day. A coffee machine needs approx. 800 - 1200 watts of power. So it won't work. I need the part to charge batteries, for which it is sufficient without any problems.

You won't find that in this price range. This one doesn't have that either.

I've been using a power strip where I've cut the plug and put a plug with a + and - connector without the ground. When I travelled, my children were able to connect their computers and cell phones to the power strip and charge them. I myself have taken a multi-socket where I cut the plug and put a plug with a + and - connector without the earth. When travelling the children were able to connect their computers and mobiles to charge.

According to information e.g. under [1] (as also with a competitor of Digitec Galaxus AG), the device weighs 0.8 kg. [1] http://www.exista.ch/prodDocuments/300w_specification.pdf

Theoretically, you can connect a power strip there. You just have to consider the total power of the connected devices and that the car battery still has some juice ;) What annoyed me a bit was that the socket is only 2-pole and has a "cover".

yes of course you only remove ~4A unless I am mistaken so no problem
