    • The LED display can be troublesome

I have used this little unit extensively for the last month or so. It is held up except for the LED display. For the price, you can’t beat it.

Review Image by Michele Pridgeon Michele Pridgeon
I bought this back in July of 2021. So this is a review for it After a few seasons of use. I use it mostly to charge 2 LiFePO4 20ah batteries on my RC Mower I built. Takes about 4-5 hours to charge my batteries up from about 10-15% charge to full. I know when the batteries are charged when it says 0.0 amps because the BMS modules in the batteries stop allowing any more power in. I normally have to set it to Manual mode to fully top off the batteries but it gets them to about 80-90% which is what you want to do to extend the battery life if your going to take it almost to 0% all the time. I had a few SLA batteries in some PC UPS battery backups I used it on to try and bring them back to life and it worked like a charm. Used it to revive an ATV battery a few times when one of my family members accidentally left the key on and the lights on for the ATV. Also used it to charge up some Deep Cycle AGM batteries on the RV. Used it to revive my old 69 Chevy's truck battery that sat dead for a little over a year. Granted I had to leave it on it for like 2 days but it did it... sadly the truck still doesn't run right but that's a different problem this little guy can't fix. Now, I've read though a bunch of the other reviews on here and other issues people have had. Honestly, never had any of those issues and its just worked great for me out of the box. So I can't say you won't get a lemon. Honestly, that's a possibility now a days on anything you buy with all the companies lowering their QC standards. But, if you need a charger give this little guy a try. Its been a good little workhorse for the farm and for the price its paid for its self. ... show more

    • Excellent Customer Service
Color: Black+Yellow
The unit underperformed in that it only would output to 9.6 A not 12A. as spec. On a low charge large car battery.. They replied the same day and refunded saying it probably has a circuit problem. There is another review that had a lower output as well. Maybe a quality control issue. Unit is simple to use however. ... show more

Tremendous charger for the money. Works like the old kind so it won't reject a battery that is flat-dead like a smart charger will.
