Why Choose a Smart Auto-Disconnect Charger?
Most standard chargers continue to trickle charge devices even after they reach 100%, which can degrade battery capacity over time. This 140W Smart Charger physically breaks the circuit once full charge is detected — not just a software signal, but a true mechanical disconnection. The result is a healthier battery and lower standby power consumption.
