Features
- Fully Automatic Charging: The charger automatically recognizes charging. If you forget to press the start button, it will start charging after 30 seconds. Once fully charged, it switches to pulse repair mode and turns off the screen to save energy, maintaining the battery at a safe voltage level for long-term storage. When the battery voltage drops too low, the charger automatically restores full output power and switches back to pulse maintenance mode after reaching full charge
- All-in-One Compatible Design: Designed for 6V and 12V sealed lead-acid batteries in cars, boats, RVs, power sports, and deep-cycle batteries, including 12V calcium and lithium (LiFeP04) batteries, as well as 6V and 12V lead-acid batteries, including STD, AGM, GEL, Wet, MF, EFB, and deep-cycle batteries. The charger also has a memory function to remember the last settings, ensuring uninterrupted charging even during long-term use without worrying about power outages
- HD LCD Screen and 8-Stage Intelligent Charging: With true 8-stage smart charging (desulfurization, soft start, bulk charge, absorption, analysis, repair, float, and pulse maintenance), it optimizes battery life and repairs batteries without overcharging or damaging them. The HD LCD screen allows you to view the charging stage and parameters at any time, keeping you informed of the charging status.
- Battery Repair: Independent desulfurization and repair buttons allow you to manually desulfurize and repair your battery to restore lost battery performance, helping to revive old/idle batteries and extend battery life. If your battery cannot be charged, you can try the "repair" mode to fix it. Note: It cannot repair completely drained batteries.
- Engine Start & Winter Mode: Engine start delivers 100A current helps activating your car battery to start your vehicle in 100 seconds. Winter Mode, +0.2v on the basis of the original charging voltage, better boosts your battery activity and charges more thoroughly in low-temperature situations.
- Multi Safety Protection & ETL Certification: The charger provides multiple protections to ensure safe use, including spark-proof, reverse polarity, overcharge/discharge, overvoltage, overcurrent, overload, overheating, current backflow, short circuit, etc. The upgraded cooling system improves performance. ETL certification makes it safe to use.

Definitely worth it. I have used this multiple times for myself and to help others. If you travel, being able to jump your own vehicle without calling someone else is a huge time saver. It’s easy to charge and easy to use. I have a King Ranch that hadn’t been started in months. It turned the battery immediately. This would be a great item for your college age children or honestly any driver.

Not a fast charger if the battery is low but does a good job and identifies bad batteries. Easy to use

I'm giving it 4 stars, because a few things bugged me about it. I bought this for my GF and her daughter. I did not do my normal research but this had a lot of high ratings so I bought it. Trying it out myself, some things surprised and aggravated me. It was extremely small and light, unlike other chargers I have. I assume this is because it's not a high amperage charger. The clips for attaching to the battery or other connection points are not copper. I'm no expert but pretty sure I've never seen a charger with non-copper clips/clamps. I assume the clamps are less conductive than copper, but is that a big deal here....probably not. The plastic protection on the clamps is so thick I could not clamp to the side-mount terminals on my truck battery. And yes, I know you should not connect directly to the battery, but I sometimes do. Had to connect elsewhere. I connected to my seldom-driven truck and the charger indicated the battery was at 60% charge. It charged for about a minute or two before I decided I needed to reposition the charger. When I reconnected the charger almost immediately, it indicated 100% charged, and would not start charging. I assume (like a lot of smart chargers) it was thrown off by the 2-minute surface charge (again, I am no expert). I could not get the charger to start charging again until I turned on the headlights to drain the battery a little, then reconnected the charger and all was fine. The charger showed this same peculiarity with other batteries. I should look at the instructions to determine if I need to do something different, but I've noticed when the charging is complete, the unit appears to shut off completely. Maybe it's a timing thing but when left charging all night, the charger appears dead the next morning; nothing on the display, which bothers me. It immediately shows 100% charged when you turn it back on. All in all, a great charger for my GF. It has the usual protections against reverse hookup and all that. The display continuously rolls through various status screens and is informative. Again, except for a little aggravation, I'd have given it 5 stars.

Very happy with this battery charger. I like that it charges standard, AGM and LiFePO4 batteries using the correct profiles for each. I especially like the charging status display so I can see what is going on during the charging process. This unit has all the features I was looking for in a compact and lightweight form factor.

I’m in an industry that uses a LOT of 12 volt battery chargers every day. This one is easy to use, easy to read, hard for trainees to mess up with. Coming in the next day to uncharged batteries is a Very Bad Thing where I work. This charger passes all the tests. It charges quickly enough, and doesn’t have a complicated usage. Some chargers need a double click. Some chargers need to make sure you push THIS button and not THIS button. Some chargers take forever to give you a reading. Some chargers if you push the wrong button, you’ll ruin the battery. This one is hook it up, it instantly shows you the percentage. Push the one button, off it goes. Display changes to show that it’s charging. Done and done. This one seems to last longer than many other types as well. The clips also seem to be well attached. Some clips pull off easily. These are strong clips that are well attached. Clips are important when you use this daily. These are good clips. My company uses probably 10 or 12 different kind of 12 volt battery chargers. This one is my best recommendation.

Dan thing worked on the first go!!! Love it!!!

i hook it up it makes noise then noise stops it does its thing then shuts off i dont know if thats write or if its actually charging, ,i put it on repair mode and it screwd up my battery i wasnt expecting that , bioled that battery good , usally the repair wet quick and stops, but for some reason it did not , it would be cool to charge the battery at 2amp setting for a good amount of time but it keeps shutting off , i have a manual charger that i use for 2 amp charging, this battery charger reads differant than my teater, , im not sure if this right or what but does charge ,and i guess it works maybe not exactly what i wanted my old one was automatic , maybe i just need to by a more expensive heavier one, this one is small and light , and all that to ligjt for serious use, so ratinh it would be difficult ,i like to have a charger that has a temportature sensor that will automatically shut off when battery gets to hot , so incase i forget to turn off charger it will sence heat and shut off, but will keep charging on 2amp and not shut off unless battery gets too hot, also another idea a buit in timer ,in the book it reads if the battery has a certain amount of volts to charge it on 2amps for 13 hours it wont do that at all , but it will charge it up but volts dont last ,but maybe its not deaigned for that, repair mode deatroyed my battery just one battery , i but other batteries and its fine , i dont think i could give a fair rating it is what it is, so i could say it works and still works, its very light all other ones are heavy so this would be lower powered one but its a nice little charger for the normal person , im more of a hard core user , so price for normal ise is fine, but for more serious charging step up to more power ,
