The Smarter Way to Stop Charging
Automatically disconnects the power when charging is complete.
Instead of leaving your device connected to the power source indefinitely, is designed to physically disconnect the charging connection once the charging cycle is complete.
Charge. Disconnect. Done
It Doesn't Just Stop Charging
Sentry is designed to physically disconnect the power connection when charging is complete.
That means your device isn't simply told to stop charging — the power connection itself is disconnected.
Charge Smarter. Sleep Better

Frequently Asked Questions
Will it slow down my charging?
Will it slow down my charging?
No. Sentry passes through up to 140W (USB PD 3.1, QC, PPS), so your device charges at its normal maximum speed until it's full. Actual speed depends on your device, charger and cable.
Is it compatible with my device?
Is it compatible with my device?
Yes, if your device has a USB-C port — iPhone 15 and newer, Samsung Galaxy, Google Pixel, iPad, MacBook, Nintendo Switch, Steam Deck and more. It doesn't fit Lightning iPhones (iPhone 14 and older).
My iPhone already has "Optimized Charging". Why do I need this?
My iPhone already has "Optimized Charging". Why do I need this?
Optimized Charging only delays reaching 100% — the charger stays connected and keeps topping the battery up. Sentry physically cuts the power once it's full, and it works the same way on every device you own.
Do I need an app or batteries?
Do I need an app or batteries?
No. No app, no Bluetooth, no batteries. It's powered by the charger itself.
