Note: Our products have EU / US / plugs. If there are other specifications for plugs, please inform us.
Protective functions:
1. Overcurrent protection at the input
If the input current exceeds 2A, the charger will turn off the fuse to avoid internal circuit breakdowns leading to fires and other risks.
2. Overcurrent protection at the output
A charger with a lithium-ion battery for charging current is limited to a certain range to maintain safety and battery life.
3. Short circuit protection
If the charger is used improperly, the output current of the charger will be 200 ormA to avoid damage.
