The charger output voltage is 4.2V, the standard current is 0.5A, and the limiting current is 0.6A. The material is solid, and the 13001 (0.5A) triode for low-level power supply is discarded. The 13003 (1.5A) triode is directly used, which makes the power margin very sufficient. Even under extreme conditions, there will be no malfunction.

Basic parameters: 

 Output voltage: 4.2V 

Output current: 550 mAh (3.5 round hole plug)

 Input voltage: 220-240V

Can charge lithium battery 18650/ 17670 / 18670 AC + DC, for home use, in-car use.

Instructions: Output 2 lines, the output is green and the light is in the normal standby state. When charging, it is red. The indicator status indicates:

The green light is standby (4.16V turbulent state when charging) Red light is charging! Flashing red light for battery failure or short circuit

The two chargers and the battery are connected in series directly to the 7.2V (also balanced charger) charger! The input is 100V-240V, the output is 4.2V500mah, suitable for lithium polymer battery with capacity of 500mah-5000mah! The charger has a short circuit, overcurrent and overvoltage, and the positive and negative poles are connected to the short circuit protection! Suitable for miner's lamp, flashlight, lithium battery charging for digital products.
