Frequently Asked Questions

Q: What type of batteries is this 21V lithium battery charger compatible with?

A: This 21V intelligent charger is designed to charge 18V lithium battery packs, commonly used in cordless power tools such as drills, saws, and screwdrivers. Its smart IC chip ensures safe, accurate charging for lithium cell packs.

Q: What safety protections does this charger include?

A: The charger features a comprehensive multi-layer protection system — including a smart IC chip within a flame-retardant ABS+PC housing — that guards against overcharge, overvoltage, overcurrent, overheating, and short circuits, keeping both your batteries and connected devices safe during every charging session.

Q: What is the difference between the 1A and 2A charging modes?

A: The 1A mode provides a slower, gentler charge — ideal for smaller battery capacities or overnight charging. The 2A mode charges faster, making it more suitable for larger capacity packs when you need a quicker turnaround. Both modes are managed intelligently by the built-in IC chip.

Q: What is this charger made from, and how durable is it?

A: The charger housing is constructed from a high-strength flame-retardant ABS+PC composite material, offering scratch resistance, drop resistance, anti-aging performance, and high-temperature tolerance. The cable uses a pure copper core with PVC insulation for reliable, long-lasting power delivery.
