The charger features independent charging channels, allowing you to charge anywhere from 1 to 4 lithium rechargeable batteries simultaneously, with a maximum current of 2.5A. It will stop charging intelligently once the batteries are fully charged. The charger's microcomputer control technology and built-in intelligent circuits provide protection against overcharge, overdischarge, overcurrent, overvoltage, overheating, and short circuits, ensuring the safety of the batteries.

The 18650 battery charger has a Type-C input port, allowing you to charge it using a 5V/2A power bank, adapter, laptop, car charger, mobile phone charger, or USB wall charger, making it convenient for charging anywhere and anytime. The portable size also makes it easy to carry when traveling.

The charging indicator lights will turn red during charging and green when the batteries are fully charged. The charger will protect your batteries by stopping the charging process once they are complete, regardless of how long they remain in the charger.
