Review on 🔋 MiBOXER Smart Universal 4-Bay Charger with Automatic LCD Display for Fast Charging of 18650, Li-ion, LiFePO4, Ni-MH, Ni-Cd, AA, AAA, C, 18350, 18500, 18700, 20700, 21700, 26650, RCR123 Batteries by David Carclub

In this test the MiBoxer C4 Smart Charger (Version 4) with capacity measurement (4th slot only). I was able to charge two 26650 Li-Ion batteries to 4.2V, one AA Ni/MH (Nickel Metal Hydride) battery to 1.4V, and one 18650 Li-Ion battery to 4.2V in 4 fully charge available slots at the same time. Excellent heat dissipation. All batteries were slightly warm and not hot during the charging process, as the charger automatically adjusts the charging current according to the characteristics of the battery. You can also set the charging current manually from 0.1A min to 1.5A max depending on the battery type. Automatically stops charging when fully charged. This device measures the actual battery capacity (mAh) in slot 4. To do this, insert the battery into slot 4. Simultaneously press the "Slot" and "Mode" buttons until the "Timer Counter" on the right side flashes "0000mAh". At this point, hold and release the "Mode" button, then quickly press the "Mode" button again. This should enable three small "arrow icons" above the battery capacity icon. One of the down arrows should flash. If this is the case, it means that the battery is being charged. The down arrow changes to an up arrow when charging is complete and the DISCHARGE (down arrow) cycle begins. This continues until the battery is empty, after which the battery capacity is displayed. And then the charger fully charges the battery again. I'm glad I bought the MiBoxer C4 Smart Charger (Version 4) which works as advertised and is very good value for money. Highly recommended for its quality finish, features and performance.
