Liitokala Lii-M4S USB-C 4 Channel Smart Charger for AAA AA 18650 21700 Battery Capacity Tester Touch Buttons

Firstly, Touch control and Type-C DC5.0v input. 4 selectable charging currents: 300mA x4, 500mA x4, 700mA x2, 1000mA x2.Two discharge currents: 250mA x4, 500mA x4. Also, it can charge multiple battery types simultaneously (26650/18650/21700/AA/AAA, etc.).Single LCD screen displaying mode, voltage, current, time, and capacity. in addition there are 4 modes: CHARGE, DISCHARGE, TEST, STORAGE, allowing independent operation across multiple channels.

• CHARGE: Monitors charging capacity with independent current selection.
• DISCHARGE: Monitors discharge capacity with selectable currents.
• TEST: Detects capacity through full charge, discharge, and recharge cycles.
• STORAGE: Maintains lithium-ion batteries at a 3.70V state.

Comprehensive safety protections: Besides the Liitokala Lii-M4S includes overcharge, over-discharge, short circuit, reverse battery detection, and intelligent faulty battery detection. Additionally it Offers 5V/1000mA USB output (active only on the fourth channel) besides a reverse polarity protection.
