It accepts a wide input range (100-240V, 50/60 Hz) and up to 120W, making it suitable for use in many regions. Typical recharge times are around three hours or less, depending on the battery’s state and temperature.

Clear indicators and built-in safety

An integrated LED communicates charging status and readiness. Red means charging, a flashing red indicates high temperature, and solid green confirms a full charge. The charger includes protections against short circuits, over-current, overload, and over-temperature, with CE, FCC, and RoHS certifications.

  • LED indicators provide at-a-glance status
  • High-temperature alert triggers cooling before charging

Practical use and care

The unit is compact and wall-mountable, helping keep a tidy workspace and making battery recharges convenient during busy seasons.

After heavy use, allow the battery to cool for at least 10 minutes before charging to optimize performance.
