High-Speed USB-C Battery Charger: The highest charging current for a 3.7V lithium battery charger can reach 2000mA (limited to slot 4 only), 1000mA for two batteries, and 500mA for four batteries. The charging current for 1.2V Ni-MH/Ni-CD rechargeable batteries is 500mA. Charge Anytime & Anywhere: The 18650 battery charger is powered through a USB port, allowing you to supply power to it via a PC, adapter, portable power bank, or car charger, making it incredibly convenient. Multiple Protection System: The smart aa battery charger features a 0V/low-voltage activation function, as well as functions for thermal and overcurrent protection, overvoltage protection, short-circuit protection, overcharge protection, and the detection of non-rechargeable and defective batteries. What You'll Receive: 1 Dlyfull M4S 4 bay battery charger, 1 Type-C cable, user manual, 24-hour customer service, and a 1-year warranty. (Note: Do not charge non-rechargeable batteries.)

Product Specifications:

• Input: DC 5V 2A (Type C 6P)

• Output:

         Ni-MH/Cd: DC 1.48V, 500mA*4 ±10%

         Li-ion: 

         4.20V, 2000mA*1 ±10% (Slot 4 Only)

         1000mA*2 ±10%

         500mA*4 ±10%

• Adaptive Charging: When external input falls below 5V/2A, the charger automatically adjusts the charging current. In case of insufficient input power, all four slot LEDs will flash to indicate low power.

Product Highlights:

• Four Independent Charging Channels: Each channel charges independently, ensuring zero interference between slots.
• Type C Input Interface: Stable and convenient charging performance with a Type C input.
• Compatible with a Wide Range of Battery Types: Supports 3.6V/3.7V Li-ion batteries such as 10340, 17335, 17500, 17670, 18350, 18500, 18650, 18700, 20700, 21700, 26650, and 1.2V Ni-MH/Cd batteries including AAAA, AAA, AA, A, C, and SC sizes.
• Clear Charging Status: Blue LED lights indicate the charging status, with each slot featuring four LEDs that represent battery levels at 25%, 50%, 75%, and 100%.
• Intelligent Features: Equipped with 0V/low-voltage activation and smart identification of damaged batteries, along with multiple protection functions to ensure safe and efficient charging.
• Professional Charging Techniques: Lithium-ion batteries benefit from a professional three-stage (TC-CC-CV) charging process, while nickel-metal hydride batteries are charged with a pulse-charging method.
