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....

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

[-] TimLovesTech@badatbeing.social 10 points 4 months ago

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.

People receive a free superconductor pair of wires and still complain!

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 reported it to ebay.

Yeah, good luck with that, eBay has just become another Amazon/Walmart/AliExpress/TaoBao/AliBaba/Temu/Shein drop-shipped Chinese e-waste storefront. This kind of shit is their bread and butter.

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

[-] Chewie@slrpnk.net 6 points 4 months ago

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

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

[-] Zorsith 8 points 4 months ago

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

[-] ZILtoid1991@lemmy.world 2 points 4 months ago

I have a feeling that the main reason behind the melting is the GPUs drawing way too much power, even at stock speeds.

[-] svc@lemmy.frozeninferno.xyz 5 points 4 months ago

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

[-] perestroika@slrpnk.net 5 points 4 months ago

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). :)

[-] Ulrich@feddit.org 4 points 4 months ago

It's not dangerous, you'll just instantly pop the fuse. Most likely the power rating is just a blatant lie, much like the cornucopia of Chinese flashlights on Amazon rated at 2,000,000 lumens.

[-] MysteriousSophon21@lemmy.world 3 points 4 months ago

yeah those amazon listings are ridiculous, i've seen "9999999 lumen" flashlights that can barely light up a room lol. if you're looking for legit flashlights with actual specs, check out gearscouts.com/flashlights - they compare the real specs so you don't get scammed.
