Advanced Household Battery Charger：Our patented slot design allows for 6 slots in a compact form factor, making it incredibly convenient. Simultaneously charge up to 4 small batteries (AA, AAA) or 2 large batteries (18650/21700) with independent operation for fast and simultaneous charging. Universal Battery Charger：R4 EVO supports AA*4 or AAA*4 batteries in a single charge and can accommodate a range of rechargeable batteries. With support for 19 different battery sizes, including AAA, AA, 10440, 10500, 12500, 13500, 14500, 14650, 16650, 17650,17670,18650, 18700, 20650, 20700, 21700, 22650, 26650, 26700. Intuitive IPS LCD Display：The battery charger 4 bay features a clear IPS LCD display that provides crucial information. Choose from 7 working modes such as charge, discharge, destroy, store, analyze, cycle, and activate(refresh). Stay informed about charging progress, battery type, charge percentage, volume, time, temperature, voltage, current, and even view the capacity change curve in real-time. Efficient Type-C USB Fast Charger：Enjoy the convenience of the Type-C USB input with up to 36W maximum charging power and support for QC/PD. No need for specialized cables or adapters—simply use the Type-C port as an input. Charge your batteries using nearby tools like power banks as power sources. Comprehensive Protection Functions：Rest assured knowing that this smart charger prioritizes safety. It displays an error symbol in case of battery reversal or short circuit. Once your batteries are fully charged, the charging process stops automatically, preventing overcharging. Additionally, the smart charger can even revive over-discharged batteries. If a damaged battery is detected, the charger halts charging and displays an error on the LCD, ensuring maximum safety for your batteries ⚠️Ongoing Optimization of Charging Performance: When you update to V2.0 with the ISDGo(PC) from ISDT office website: Ni-mh batteries: Improved charging efficiency and accuracy.
