Had a dead battery (lead acid) on our home generator. Put the new charger on for 24 hours and the battery is now fully charged and it started the generator. Instructions were straightforward but needed a magnifying glass to read. Says it works as trickle charger/maintainer. Power cord is short. Needed an extension cord. Some reviews say trickle doesn't work. I'll test that and update this review if any problems. Otherwise, charger works as advertised. ... show more

    • Excellent Value
Very fast and reliable charger for your car or truck. It has a slim design and is light weight with a bright display that shows not only that it's charging, but it also tells you whether your battery is good or not and maintains charge once full strength is reached.

    • Works great
Got this because our generator battery stopped working. Also wanted a trickle charger for my truck since I don't drive it often. Automatically detects battery status. Was amazed. Charged up battery voltage and started upping the amperage on the battery. Tells you how many amps the battery needed to full charge. Son's friend car died while staying at our house. Put this thing on his car battery. Somehow his battery dropped 9 amps overnight. It's slow but it charged his battery with no problem. Only complains are the short power cord and gator clamp cables. Will probably make some modifications to make the removal. ... show more

    • Works pretty well! 10+ amps

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! ... show more

    • Worth every penny
Dreaded dead battery 1 month after the 3 year guarantee ends... of course. I don't drive that much so no big deal. Previous car battery charger also went to garbage for whatever reason. Anyhoo.. ordered this product up after reading the awesome reviews (thanks!) and it was delivered within 12 hours. Easy peasy instructions to follow and learned a little something about car batteries. Went through the process and it did the job perfectly. Diagnostics told me what was wrong with the battery. 6 hours later, good to go and back on the road comfortable enough to drive to the store to buy a new car battery. Excellent product. ... show more

    • Not made to jump start
This is a trickle charger. Took about 45 min. Great if you're home. Is not a substitute for jumper cables. If your stuck somewhere with no electrical outlet, this is not for you. I used with a heavy green extension cord and my outside outlets. I really like this it works for exactly what I need.
