KUWAJIA 140W Smart Auto-Unplugger: The Ultimate Battery Guard for Fast Charging and Overcharge Protection

140W USB-C Smart Charging Guard with Auto Cutoff

$17.99

Stop overcharging. This inline USB-C guard sits between your charger and cable and physically disconnects power once your device is full, so phones, laptops and tablets don't sit at 100% all night.

Auto cutoff: detects a full charge and opens the circuit for near-zero standby current.
Up to 140W pass-through: supports USB-C PD 3.1/3.0 and QC 4+/3.0, so fast charging still works.
Two modes: white LED mode for phones and laptops; blue LED mode for power banks, shavers and small fans.
Works with most USB-C devices, including recent iPhones, Samsung phones, MacBooks and Steam Deck.
Protection: over-voltage, over-current and short-circuit protection in a flame-retardant, pocket-size shell.
