Features:
●Charging mode: Users can press the current switch button on the right side of the product to switch 0.5A / 1A / 2A these three current modes to meet the needs for different     specifications of 3.7V cylindrical lithium battery charging.
●The product applies to IMR/Li-ion: 10440 14500 14650 16340 16650 17650 17670 18350 18490 18500 18650 18700 22650 20700 21700 22700 25500 26650 26700.
●Circuit anti-reverse function: When the charger is in the charging or standby status, if the channel positive and negative short circuit, cross-short circuit, the battery itself short     circuit, or the battery positive and negative direction reverses, the product protection function will promptly start, and won’t damage the charger.
●Overcharge Protection and Automatic Detection of Charging Function: When the users start to charge the battery, if the battery’s voltage <4.18V, the charger starts charging     function, charge the rechargeable battery.
●When the battery is full, the charger starts overcharge protection and stops charging automatically. If not removing the battery for a long time after charging, the charger will   consume a certain amount of battery power. When the battery voltage is lower than 4.0V, the charger restarts the charging function (Not for AA or AAA batteries).
