ISDT C4 EVO 18650 Battery Charger for AA AAA, 4+2 Slot LCD with Capacity Detection and Activation/Destruction Functions, Automatically Identify Type, 1.5V Li-Ion NiMH 21700

【Professional Battery Charger & Analyzer】 More than an ordinary AA AAA battery charger, the ISDT C4EVO combines Charge, Discharge, Cycle, Storage, Activation, and Analysis modes for daily charging, battery maintenance, capacity testing, and performance comparison. Ideal for photographers, RC hobbyists, technicians, and rechargeable battery users. 【Supports Multiple Rechargeable Battery Types】 Compatible with Li-ion, LiFePO4, NiMH, and NiCd rechargeable batteries, including common AA, AAA, 10440, 14500, 16340, 18650, 20700, 21700, and 26650 sizes. It also supports compatible 1.5V rechargeable Li-ion batteries after updating to firmware V2.0.0.1 or later. Always select the correct battery chemistry before starting. 【Four Independent Slots with Adjustable Current】 Four independently controlled charging bays automatically monitor voltage, current, capacity, time, and internal resistance for each battery. Charging and discharging current can be adjusted to suit different battery capacities. For smaller batteries or quieter, cooler operation, reduce the current to approximately 0.6A or lower. 【Color Display & Advanced Battery Data】 The full-color display clearly shows real-time battery information for every slot, helping you check charging progress and compare battery condition at a glance. Analysis and Cycle modes can measure usable discharge capacity, making C4EVO a practical battery capacity tester for sorting and maintaining rechargeable cells. 【USB-C Fast Charging Input—Adapter Not Included】 Powered through USB-C and requires a compatible QC or PD wall adapter rated at 18W or higher. A 36W power input is recommended for better multi-slot performance. The package includes the C4EVO charger and USB-C cable; the wall power adapter is not included. Insufficient input power may reduce charging speed or cause unstable operation.
