Plug In
Input: AC100-240V 50/60HZ 0.8ACharging voltage: DC 8.4V/12.6V/16.8VCharging current: 1A/2ACharging mode: CC-CVCharge indicator: Red light = charging, green light = fully chargedCharger port: DC5.5 x 2.1-2.5mm/ DC3.5*1.35mmSecurity protection: OVP/OCP/overload protection/short-circuit protectionApplication: Lithium batteries (lithium-ion batteries, lithium polymer batteries) the nominal voltage of the battery pack is 7.4V-8.4V/11.1V-12.6V/14.8V-16.8V Note: Our products have EU/US/UK/AU plugs. If there are other plug specifications, please message us. Protective functions:1. Input over-current protectionWhen the input current is greater than 2A, the charger will cut off the fuse to avoid internal circuit abnormalities causing fires and other risks.2. The output current protectionLi-ion battery charger for charging current is limited to a range to maintain battery safety and battery life.3. Short-circuit protectionWhen the charger is improperly used, the charger output current will be 200mA or less to avoid damage.
