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.

How about a solar battery maintainer.. saw a 10W for <$20.. it can simply stay connected all the time thru cigarette lighter plug.. no need to take out all the time like these ones…
