5.0 out of 5 stars Works pretty well! 10+ amps
Reviewed in the United States on November 2, 2024
I had two bad car batteries that were not able to restore but oh well. One would charge to only 4volts so it was really bad. The other one would charge to 12+ volts but even after multiple restores and charges it was just too weak to restore.
For my newer batteries this charger worked great! My motorcycle battery is about 1yr old AGM style and it detected AGM right away.
Always connect the +/- Charger leads to the battery first! That will detect the correct battery and give you it's current state of charge before plugging it into the wall.
Double check your battery type and just touch the only button on it to change types.
It's extremely simple to use and might even bring older batteries back to life. It didn't work on my two but I didn't think they were able to be saved anyway.
Charges very fast and even went to 10.4amps on my motorcycle battery immediately.
The pulse charge style appears to send pulses of voltage to try and restore a battery. My battery meter was jumping from 12 to 15v during the restore pulse charge setting.
So far this appears to be a very smart and tiny charger for the money.
Only issue I would say is that the leads are maybe 2ft each and that's it!

4.0 out of 5 stars Ok charger for the price, but quirky
Reviewed in the United States on November 27, 2024
This 10A charger works OK, but there are several quirks that made it a little tough to figure out, especially if you follow the instructions.
Connect the clips to the battery first. Select the mode you want *before* plugging it in as it will NOT allow you to change the mode once it starts.
Many reviews complained that it does not automatically go into float charge mode after a charge cycle. It will only do that if you select "Motorcycle" mode. In any other mode it will complete charging and stop without going into float mode. So if you want to leave a battery for a long time without being used, select "Motorcycle" mode.
Part of most of the charge cycle is the desulfate phase for 5min before charging begins. This is the same thing as "Repair" mode. However, when Repair mode is selected, it will run the desulfate pulsing for several hours to try and dislodge any buildup on the plates inside the battery. Running "Repair" mode periodically on a healthy battery can often extend the useful life of a battery. If you wait until a battery is already at the end of its life, it is unlikely the "Repair" mode will save it.

5.0 out of 5 stars Works very well....
Reviewed in the United States on November 5, 2024
I have 3 of these chargers. I use them as battery maintainers but they are fast chargers as well. 10 amp charging is a rapid charge. After the first repair, I keep mine set on the Motorcycle setting. They automatically come on as needed and usually for only for a brief time. I have batteries in my Harleys that are about 7 years old. The desulfating mode keeps the plates in the battery from collecting sulfer on them and that keeps the batteries in tip top shape. It won't keep a battery from failing on the longest end but it does help them to last longer. I have a number of other trickle chargers that are similar. I bought these because they are priced just right and they have all the features anyone would want and need. I would suggest running the repair option a couple times a year. And then set it on the Motorcycle setting. This will work just fine for any battery setting idle without being used much. I keep one atttached to my truck just because it's not a daily driver. I added quick connect leads as a duel connection to aid in fast connecting. My batteries are all set up with quick connects. I rarely use the clips but I didn't defeat them. I like that these clips are well insulated. -> Buy it. It works well.
