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

Whether you are using LED flashlights, Rechargeable USB Fan or Toys, the Liitokala Lii-M4S versatile battery charger offers a one-stop solution for your AAA AA or 18650 rechargeable batteries. Also, it automatically detects battery type (Lithium-ion or Ni-MH) and polarity, eliminating any guesswork. Alternatively choose between 300/500/700mA or 1000mA charging current for optimal speed based on your battery needs.

Moreover, a LCD display keeps you informed of real-time voltage, current, time and capacity. Compatible with a wide range of battery sizes, including AAA, AA, C, 14500, 18650, 21700, 26650 and RCR123 Lithium-ion. Furthermore you can charge not just one but 4 batteries independently at the same time. All in all charge any combination of batteries irrespective of size and type.

Liitokala Lii-M4S Specifications

Brand: LiitoKala Model: Lii-M4S
Input power: Type-C Input voltage: DC 5V/2A
USB output: 5V—1000mA
(The higher voltage lithium battery must be connected to the 4th channel,
the USB output will hence be effective, and the 5V electronic products can be powered at this time.)
TEST Discharge current: 250/500mA
Lithium battery charging current: 4.20V 300mA*4/ 500mA*4/ 700mA*2/ 1000mA*2
NiMH battery charging current: 1.48V 300mA*4/ 500mA*4/ 700mA*2/ 1000mA*2
Compatible with:
Li-ion:26650/22650/21700/18650​​​​​​​/18490/18350/17670/17500/17355/16340/14500/10440/AAA/AA/SC/S etc..
Ni-MH and NiCd: A, AA, AAA, SC

Liitokala Lii-M4S Features:

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/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.
