Auto Power Off USB Type C Charging Cable
Auto Power Off USB Type C Charging Cable
Stop Overcharging.
Protect What Matters.
The world's simplest upgrade to smarter, safer charging.
Every night you plug in your phone and hope for the best. But staying at 100% for hours quietly degrades your battery — shortening its lifespan charge by charge. The SmartGuard Auto Power-Off Protector physically cuts the power the moment your device hits full charge. No app. No settings. Just plug in and forget it.
Unlike software-based solutions, this protector physically ejects the power supply at 100% — no current, no trickle, no risk.
Overcharging is one of the biggest causes of battery degradation. By cutting power at full charge, your battery stays healthier — longer.
Charge while you sleep without worry. The auto-disconnect halts all current flow, reducing heat buildup and eliminating overcharge risk entirely.
Excess charging generates heat that wears down components over time. Auto power-off keeps temperatures low, even during long charging sessions.
Designed to work with virtually any USB-C cable and a wide range of USB-powered devices — smartphones, tablets, earbuds, portable speakers, and more. One protector, every device.
Three Steps to Smarter Charging
Compact enough to carry anywhere, smart enough to protect everything. One tiny accessory — a massive difference in battery health.
