    • Lifesaver! Revived My Dead RV Battery Overnight - 2nd one purchased to keep in RV
I can’t say enough good things about this Smart Battery Charger! I recently drained my RV battery completely after accidentally leaving my lights on overnight. It was at 0 charge, and I thought I was in for a major hassle. I needed a fix fast, so I ordered this charger and had it drop-shipped to my location within 24 hours. As soon as it arrived, I hooked it up to my RV battery, and the smart LCD display immediately gave me real-time voltage and battery status. The trickle charge and repair mode worked like magic! By the next morning, my completely drained battery was fully charged and ready to go—no expensive $200.00 replacements, no stress. I love that this charger is fully automatic, adjusting based on temperature and battery condition. Plus, the multiple safety features (overcharge protection, short circuit prevention, and thermal sensors) give me peace of mind when using it. This charger is a must-have for anyone with an RV, car, boat, or even a motorcycle. It’s compact, powerful, and super easy to use. It not only saved me from a dead battery but also extended its life with the built-in desulfator. If you ever find yourself stranded with a dead battery, this is the tool you’ll be thankful you have! 5 stars all the way! ... show more

I needed a battery charger/tender to flash my ecu and tune my car but didnt want to spend excessive money for something id use once. This was easy to use even for someone with almost no mechanical knowledge, it really is fool proof. The chargers smart and knows what to do so all you have to do is connect it, plug it in and select a mode. I used the standard car mode while flashing and ran into no issues. Id recommend this for anyone wanting to tune their car, but it also has lots of other useful features ill most likely use in the future: ... show more

    • 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

    • SUPER POWERS!
This item looks exactly like the listing photo's. My car battery was D E A D! The multimeter said 3%! It's winter and I forgot about battery maintenance in winter. I'm an older woman but not lacking knowledge and skill. Filled my battery as it was a little low, then scrubbed my rusty cables with some baking soda paste, and a wire brush. It almost wanted to turn over but wouldn't, so I got online and found this charger. It took 8 hours to charge the battery all the way to 12.5. I did bring it inside my apartment to charge, I didn't want the cold and rain to affect the charge. Needless to say I was very happy when I checked it with the multimeter hours later and it was fully charged. This item is small, convenient, lightweight but sturdy. It has an easy to understand instruction pamphlet, and you do need to read that first if you have never used this kind of item because there are different settings for different charges. But it was all in all very easy and for such a small thing it has Super Powers! It has a quiet fan that runs while it's charging. For less than $25, everyone should have one, you never know! ... 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

    • Works very well....
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. ... show more
