Field charging LiPo batteries

[aerokam]

That 500mW is for the AC wall socket adapter which I assume comes with the unit so you can charge it up from the your house 110V mains voltage supply. The "DC Accessory Outlet" just states 12V with no current rating, so who knows what current it can supply. I bet it has piddly thin wires soldered / connected to the back of the cigarette socket which means the current capability is going to be limited by those alone, and the probably have PVC sheathed wires which will melt and potentially catch fire if you try to draw too much current through them.

It's a bit of a ghetto solution but just have an XT60 with two wires coming from it with bare stripped / tinned ends. Then clip the jump start croc clips to the bare wires. Obviously be careful to get the polarity correct !!

Thanks. I don't remember getting any AC adapter with it. There's a male 2-prong input that I just plug an extension cord into to charge it. I was puzzled what the AC adapter was all about.

So there normally wouldn't be some sort of current limiter that limited the output current to whatever the unit could handle?

The adapter at Amazon is cheap, so I'll get it and see how it works. I'll also try the ghetto solution--I have several XT60 connectors with leads, so that's easy to try.

We've been 100% EV since 2017, so I have no use for it as a jump starter anymore. Last time it was put to good use was when my daughter borrowed it to go camping some years ago. Her battery tended to die on her longer outings, and they also used it to charge their cell phones. We keep it just as an emergency cell phone charger in case of power outages. Figured I might put it to some use if possible.
