(With a precise constant current charging characteristics, charging the results are satisfactory, the battery will not overcharge) INPUT SPEC:AC100-240V 50/60HZ 0.8A Charging voltage:DC16.8V Charging current:1A Charging mode:CC-CV Charge indicator:Charging the red light is full of green light Charger port:DC5.5*2.1 Product size:76*43*30MM Security protection: OVP/OCP/ Overload protection/ Short-circuit protection Scope of application：Lithium batteries (lithium-ion batteries, lithium polymer batteries) the nominal voltage of the battery pack is 14.4V-16.8V capacity range 1100~5500mAh As18650,18490,14650,14500,14430 and other battery packs note：Our products have INPUT SPEC: US Plug / EU Plug, Please select the desired plug. If there are other specifications, please leave a message to us. Protective function: 1. Input over-current protection When the input current is within 0.1S greater than 1A, the charger will cut off the fuse, overcurrent protection will start off mains The impact of the charger to avoid internal circuit abnormalities caused fires and other cited risk. 2. The output current protection Li-ion battery charger for charging current is limited to a range of battery safely withstand. When the lithium battery is fully vented, filled Appliance Repair will automatically enter the state, as policyholders battery, increasing battery life. 3. Short-circuit protection When the charger improper use, resulting in positive and negative output is connected to the charger output current is 200mA or less will be small enough to protect the charge Electrical short-circuit the positive and negative output will not be damaged.
