- 7-stage smart charging & Auto-memory: Features a microprocessor-controlled 7-stage charging process that automatically diagnoses, charges, and maintains your battery to maximize its lifespan. The built-in Auto-Memory function remembers your last selected mode, so it automatically resumes charging the same way if power is interrupted or when you plug it in next time.
- Pulse Repair & Desulfation: Revitalize your battery. The dedicated Repair Mode (16-hour cycle) uses advanced pulse technology to help break down sulfation crystals on battery plates. It is designed to recover old, idle, or stratified lead-acid batteries and restore their capacity, saving you the cost of premature battery replacement.
- Smart protection & Active cooling: Built for worry-free operation 24/7. The system includes comprehensive protection against reverse polarity, short circuits, over-charging, and over-temperature. Equipped with a built-in cooling fan to effectively dissipate heat during high-amp (20A) operation, ensuring the device stays cool and efficient.

Product description
Great Charger for the price
Love this charger, the only problem is the read out on the face is not very bright and very hard to read especially with any sunlight. The charging is great it did my RV (2) batteries fairly fast. I would recommend charger if you need a good and small charger. A++
Great produc
Works great for my ATV batterys. I have a regular car battery that would not charge my four wheeler batteries so I bought this and it works wonderfully. Would definitely buy again.
Very good charge
Does everything the seller said it would do. Used the Lithium LiFePo4 setting to charge new 314 ah battery. Charged it 100 % full @ 13.4 volts. Then I used it the Repair and Desulfate settings on a Class 31 Deep Cycle Lead Acid battery. The LA battery went from maximum 11 volts prior to Repair to 12.9 volts afterwards. The only negative feature is the Screen is so Dark it’s hard to see the settings.
Simple and Works Grea
I picked up this battery charger to keep my vehicle battery topped off and it’s been working really well. It’s easy to hook up and the display makes it simple to see what it’s doing while charging. I like that it automatically adjusts and shows the battery level, so you don’t have to guess if it’s working. It feels sturdy and seems well made. So far it’s been doing exactly what I needed it to do. Great charger for the price.
