  • Charges my battery
It works! Easy to read

  • Works perfect!
Bought this to bring back to life my AGM battery inside my BMW and it did so within 8 or so hours since it only had 30% life left. Now I’m currently using it to trickle charge my 280Z that has an AGM battery.

  • Works well, worth the price (but mine has occasional reliability problem)
I've had this charger just over a year now. In 2020 I stayed home a lot and drove less than 1000 miles for the entire year. My car was frequently parked in the garage for 1 to 4 weeks (or more) at a stretch without being driven. And oftentimes trips were local and quick without enough drive time to recharge the battery. I found that after about 10 days of sitting undriven, parasitic draw would reduce my battery's voltage below 12.6V. The charging and maintaining features of this unit worked really well to keep my battery charged up and reliable. Only once (the first time) was the battery below 12.5V. The BMK charger did what was expected and never got more than barely warm during the 8 or so hours it was charging, then switched to float mode. The battery itself never got warm either. Good job! All the rest of the times I've used it, the battery was between 12.5V-12.6V when I connected the charger. As expected, it took care of charging and went into float mode. BUT 5 times during the year it did something unexpected: it turned off a few hours after doing its typical routine. I have no idea why. The temperature in my SoCal garage was always moderate or cool. When I'd see it off, I'd check AC to the changer (always on) and would completely disconnect the charger from AC and the battery. Checking battery voltage with a VO meter, it was usually between 12.8V-13.1V. After re-connection of the battery to the charger and then charger to AC, it'd still not turn on. So weird. The first time it happened I was sure it had died. But a couple hours later I tried again and found it worked just fine. More weirdness. But in a good way this time. Just recently it turned itself off for the fifth time in the past 13 months. Once again, I tried to reconnect it right away to no avail (which is what I expected). After leaving it disconnected for a couple hours, when reconnected, it worked like it was brand new. It seems to have an occasional, mysterious reliability problem. That's why I'm knocking off one star. Except for that issue, this unit has been a great help keeping my car's battery ready, even when I've not driven the car for weeks. (As long as I check on it every few days to be sure it's not turned itself off.) Update June 2022 -- It's still working just the same. Most of the time, it does just what I expect. But about every 5th or 6th time I use it, after several hours (maybe overnight or a day later) it turns itself off (and battery voltage is about 12.7V or so). After that I have to leave it unplugged from AC for at least an hour or two, then when I hook it up again, all is fine and it'll work as expected until I need to drive my car again, maybe 10 or 14 days later. Except for the mysterious turn-off glitch, it's a good product. But because I don't have confidence it'll always have my battery charged and ready, I make sure to check voltage level a day or two before I need to drive somewhere. ... show more

  • Cheap & ease of use; reliable
If your have variation of voltage from the utility (100-240), this product works as designed. I am a photovoltaic technician and use it to keep battery toped of & if a battery is lying around--it will prevent it from getting sulfated. I reached out to a name brand & I was disappointed that the rep (owner/ceo), didn't even know that his competitors have the voltage variation available like this offers. It prevents it from killing the power supply (charger) if you have constant voltage sages. I waited some time before evaluating it. It charges up to 14.4 vdc (for agm & gel batteries) & back to 13.6 vdc after the battery is charged (floating)--as it should. Have been using it for various weeks consecutively w/o a hickup. Update: I purchased a 2nd unit to maintain my 2nd car's battery & the other unit has been reliable. I recommend this unit. Works as designed, a very good price, I have had the original one connected weeks straight day-after-day. Worthy buy. Update #2: have been using this unit for months straight in a row DURING HEAVY voltage sages & outages AND OVERVOLTAGE situations (scarry situations) and to my surprise--still ticking as expected (better than). I have two other chargers doing maintenance for car batteries and I now have to purchase a replacement units (plural) for that usage. The only reason I don't purchase 1 or 2 more of this unit is because I need a higher capacity. I am going to look into seeing if this manufacturer has a higher capacity... i do like to give credit for a good quality item for a fair price. Good purchase ... show more

  • Defective out of the box
I may have a defective model, but the battery simply wouldn't charge. I thought maybe I was wrong and tried to jump my car with it - nothing. The email provided in the instruction booklet does not appear to be in order. I very carefully typed it and double/triple checked it, but it came back "address not valid." Then I emailed the company that is selling it via Amazon. There is a phone number but I ain't calling China. I asked them to please call me, figuring they must have some kind of economical system set up to call foreign customers. No call but they did reply to my question with a couple suggestions to test the charger. One was to plug it into the power source and if the charger light turned green, the unit is good. The charger light was red, as I had told them it was. Then they told me to clamp the two clips together and if the charger light turned red, the unit was good. I emailed them back to be sure I understood correctly because that sounded kinda strange but they wrote back and said yes, that's what they wanted me to do. Well the charger light was already red, because that's what happens when I plug it in. It stayed red when I attached the two clips to each other, though the led charging % indicators went crazy, as one would expect. Not sure what the purpose of that exercise was but the fact remains, I bought this item because I needed it. I had a battery that was losing its charge periodically leaving me in a bad spot at times but since I will be getting rid of the old heap in a few months, I did not want to invest in a battery. My car was sitting dead in the driveway, the precise situation for which I bought this thing, and I still had to call someone to come charge it because the charger I purchased wasn't worth the postage it took to send it to me. Amazon is sending out a new one. But regardless of whether that one works or not the point is that these things should be quality checked before being sent to customers. A defective charger is no better than no charger at all. There seem to be a lot of reviews starting the item they received was defective, defective products should be very rare. I wish I'd taken all these reports of defective items as a warning. I am most unhappy and their customer service is downright useless. ... show more
