Our community has rated this post as helpful. If you agree, why not thank TealIdea227

Making these things should require about 1/20th as much rocket science as PC PSUs ... in 2001 ... and 6A is a very functional size. The better brands that sell for 10x this price are made in the same country, providing ample opportunity to replicate the 30 year-old technology of huge chunky discrete parts attached to a microcontroller. Yet two reviews complain about problems when the battery starts off at 11.5-11.6V.

Other reviews complain about it not being wireless.

I think a couple of people thought it was a battery pack, jump start. I'm sure I can find some uses for it for this price.

Many are paid Vine voice. Even some of those are very poor scores.
Seems like a gamble. YMMV

product photos are inconsistent, making me think some are AI
does the actual display have "Large Screen Digital Display" text displayed? 🤔🤯

if it were actually decent quality and did what it claimed, it would be a steal. but I'm dubious.

This is the kind of product that is you get what you pay for. The cost of the parts is probably more than $11. No way I would connect it to an expensive battery.

I think "do nothing at all" is absolutely the best failure mode for battery chargers. Kind of sucks when it's freezing, though.

This is 50 cents cheaper than the other listing that doesn't require a coupon, so 4%. It almost pays for sales tax!!!

I wouldn't do it. Watch Project Farm: https://www.youtube.com/watch?v=dyE7krGPP2A

Most of the cheap chargers do not have a good float mode and will overcharge and ruin your battery. If I got a charger like this, it would only be used for keeping the battery charged while I'm actively working on the car, i.e. running the radio while doing things.
