This is a great product and I would advise every car owner to get it. If you have a battery that goes dead, this is the lifesaver! Not only can you charge your dead battery, but you can also trickle-charge it if, like me, you don't drive much due to COVID and/or, like me, live in very cold weather. The two together are a deadly combination. You don't have to wait for AAA or try to find someone to jumpstart your car or electric car . This will do that but it will also charge your battery to full strength. It is very, very easy to use for those who may feel uncertain about doing anything that requires cables. You just hook up the cables, plug the unit into the wall plug, select your charging profile, and you are good to go, it's not scary at all. Leave it on overnight and your battery is like new, full of energy and ready to go. This is the best product ever and the customer service people are great!

I Don't leave reviews very often, but when I do, it's to give props for an outstanding product. I had an almost depleted car battery, which our current "smart" charger would not even recognize, because of the low state of voltage the battery was in, and would immediately go to fault. I purchased this charger, because of the other postive reviews, and the fair price. It arrived well packaged in box, and then sealed up in it's own professional looking package, knew right then, not something cheap. To get to the true test, put it on the dead battery, it recognized the battery and begin charging without even having to use the force mode, detection. This little 1 amp trickle charger brought the battery voltage back up enough, to start a V6 Chevy Impala in just under 3 hrs, granted the battery wasn't fully charged, but good enough to start the car with -5 below 0 temperatures outside. Very impressed with this charger, thanks for a good product! 👍

Bought a new battery for my pickup from a major auto parts store. I don't drive my truck every week. Everytime I went to drive it, it would be dead. Took it back and they would charge it and tell me it was fine. Then it would be dead in a couple weeks. Did the long refurbish charge that took about 5 days, and have had no problem since. I checked my alternator to make sure it's charging, I also check the battery from time to time. It's always at around 12.5, while engine running around 14.5 volts. This investment saved me from going through another $170 battery. Great buy, hope it lasts!

I have a 2014 Shelby GT500 that I drive only on good days. On not so good days, of which there are many here, I keep her garaged with climate control. Because she sits for long periods, the battery drains. I had the same problem with my previous 2006 GTO, and I would have to buy a new battery every summer. A friend recommended this and I purchased it. I read the instructions, and plugged it in and attached it to my dead battery. The battery was so low that the light was a very solid red. I left it charging overnight, and woke up the next morning and the indicator was green. The car started right up. Now I don't have to worry about draining or dead batteries. I just leave this plugged onto the battery, and it will monitor for low battery and charge the battery and keep it good. Much better than paying $3-400 for a new battery!

I bought this unit hoping to bring my car battery back to life. I own a car that sits for weeks at a time during the Winter months and its battery has died multiple times. I was able to jump start the vehicle, but the battery wasn’t holding enough charge to start the car the next day. The battery is only 1 year old. I connected the unit as directed and allowed it to charge until the green light came on. In my case, the process took 3-4 days of slow charging as I was unplugging it at night. Once I got the green light, I measured the voltage and was well over 13V of starting power. I’ve since driven the car weekly and the battery is functioning as new! I will continue to use when the car has to sit for a while.
