What should I do if the W106S glue gun does not charge or flashes red?
Use a 5V/2A standard charger, clean the upright base metal contact pins, and avoid incompatible fast-charging PD protocols.
Charger Specification Compatibility
The W106S base requires a standard 5V/2A USB power adapter. High-wattage USB-PD or proprietary fast chargers may fail to negotiate voltage and shut off power delivery.
Base Contact Pin Cleaning
Inspect the pogo pins on the charging base and the gold contact pads on the bottom of the glue gun handle. If adhesive residue or oxidation coats the pins, wipe with a dry cloth or rubbing alcohol.
Battery State Indicators
Solid red indicates active charging; solid green confirms full charge. Flashing red suggests battery protection mode due to extreme temperature or low input voltage.
