1500W? At 12V that's 125A - That is fucking dangerous! Most sockets are rated at 20A. Most inverters that are >300W use crocodile clips, or preferably screw-down terminal rings. The cable looks way too thin too. That's a fire waiting to happen....

In my experience, most car sockets struggle to deliver 10 A and might be fused at 20 A (but a fuse is not a suggestion, it's a safety device). :)

Ah, I'm sure the undersized copper coated aluminum wire will be fine, just fine.

I looked it up, and the recommended cable size for carrying that voltage and amperage is practically the size of the adapter part lol

In the US you would need #2 [AWG] gauge wire to handle 125amps safely, and that's just handling the current, nothing to do with proper grounding or anything.

Also just for reference, many older homes in the US would only have 100 amp service from the pole, meaning this thing is pushing more amps than a whole house potentially.

I sort of suspect that they're lying. I feel like that cable would just melt if you put 12V/125A through it.

no kidding. Even 35A is enough to melt a 12v plug spring into the plastic surround.... don't ask me how i know....

It's ok, that 1500 watt output is only for a microsecond before all the 3 cent "power" MOSFETs inside act as fuses.

More likely, there is enough internal capacitance for the inverter to sustain one (1) half of a full-wave AC cycle at 1500W, after which the overload/low voltage cutout triggers.

Haha! I reported it to ebay. Man that was a faff, there's no category to report dangerous / lying listings. The chat system was crap too. I had to say "I want to speak to a human", and it put me through.

I've never seen that connector in a car......

[–] Zorsith@lemmy.blahaj.zone 5 points 1 day ago

Probably because its both a bad connector known for melting, and its meant for very expensive graphics cards

Not actually in this adapter, but the spirit is the same
