  • Worked for electrolysis tank
Color: Yellow
I bought this to use for a home ease electrolysis tank. Worked great for several hours of use. Sometimes it makes a high pitch whine, but disconnecting the hot cable and putting back worked to get rid of the whine.

  • Love it!
Color: Black+Yellow
Seems like a great battery charger. I have a brand new battery that I when I drive I don't go for long distances so I bought this charger to give it a good charge every once in awhile. Since doing so my battery charges at a higher rate now (alternator is charging at 14 volts through the entire trip where it used to charge at 13) it seems like getting a good charge from this charger brought the health of the battery back up. 🤷 ... show more

  • Like magic!
Color: Black+Yellow
I have been using a trickle charger from the 70’s for years. I discovered these new technological wonders while searching for best practices in maintaining car batteries throughout the winter months. This unit is light weight, seemingly well built, and with a well lit and easy to read display. Not many buttons or switches, which I like. Just connect the clamps to the battery terminals, plug it in, set to ‘Auto’ or repair and wait patiently. 😉 I’m amazed at how the newer technology can detect battery type and maintain its charge. I’m glad I chose this one. ... show more

  • Junk. Wouldn’t work out of the box. Then blew up.
Color: Yellow
I bought this in June 2021 but only got a chance to use it now, seven months later. I know…stupid. The instructions are an abomination. But it seems simple enough to use and there are really only two switches on the thing. I was charging a 12v car battery and so set it for automatic battery and ordinary charging. I connected the lead clips to the correct terminals and the screen lit up with 12.2v 00.0 amps. The fan did not go on and the charging light did not blink as the manual said they would. I waited a few minutes but nothing. Only the 12v light was lit. Nothing got warm. I disconnected the car’s leads from the battery and tried it the charger connected only to the battery itself. No difference. So I waited a few more minutes but there was no change. At this point, I tapped the top of the unit lightly and the charging light started flashing red and green. The screen now read 12.1v 7.2amps. After a minute or so, the light stopped flashing and so I tapped the unit again. It started flashing AND the fan went on. This happened two more times. The third time, the charging light stayed flashing for about 90 seconds and just as I thought it was ok, there was a loud POP and a flash of sparks out of the fan grill. I yanked the plug from the wall and disconnected it from the battery. Then I wrote this review. I’d avoid this product. You might get one that works. Or you might get one like mine. Now that I’m well out of the return window, I think I’ll try a different product ... show more
