Specifications:

Input: AC110-245V 50/60HZ 0.8A

Charging voltage: DC 14.6 / 8.4V /21V(Discretionary Consumption)

Charging Mode: constant current and constant voltage, full self-stop

Charge indicator: Red light = charging, green light = fully charged

Charger port: DC5.5 x 2.1mm

Security protection: output-current protection/over-load protection/short-circuit protection

Application: Lithium batteries (lithium-ion batteries, lithium polymer batteries) the nominal voltage of the battery pack

Line Length:90cm/35.43inch(approx.)

Package Include: 1Pc x Lithium Battery Charger

Protective functions:

1. Input over-current protection

When the input current is greater than 2A Max, the charger will cut off the fuse to avoid internal circuit abnormalities causing fires and other risks.

2. The output current protection

Li-ion battery charger for charging current is limited to a range to maintain battery safety and battery life. 3. Short-circuit protection

When the charger is improperly used, the charger output current will be 200mA or less to avoid damage.

To check if 16.8V charger compatible with your tools:
1.Look for your battery's voltage rating (usually printed on the battery pack)
2.Check if your battery has a DC 5.5 x 2.1mm / 5.5 x 2.5mm connector
3.Confirm your battery is lithium type (not LiFePO4 or other chemistry)

Tips:

The current of the constant current constant voltage charger changes with the voltage.

If the battery is charged when there is no power, the charging current is maximum at this time.
