Frequently Asked Questions

Q: How does the smart auto cut-off charging adapter know when the battery is full?

A: The adapter monitors the real-time current and voltage flowing to your device. When it detects that the charging current has dropped to the level typical of a fully charged battery (trickle charge phase), it automatically cuts the power supply. It does not interfere with or access the device's battery management system.

Q: Can I use this Type-C auto cut-off adapter with my smartphone while it's on?

A: Yes! Simply select White Light Mode by pressing the button. Since screen-on devices continue drawing a small amount of standby power, the adapter will automatically cut power approximately 10–50 minutes after your phone or tablet displays 100% charge — ensuring a truly full and safe charge.

Q: Is this charging adapter compatible with all Type-C and Lightning devices?

A: The adapter supports a wide voltage range of DC 5V–28V and currents up to 5A, making it compatible with most Type-C and Lightning devices including smartphones, tablets, Bluetooth headsets, power banks, electric shavers, and many laptops. Note: Fast Charge protocols (e.g. PD, QC) are not supported.

Q: Is it safe to leave devices charging unattended overnight with this adapter?

A: Absolutely — that's exactly what it's designed for. The auto cut-off feature ensures power is disconnected once your device is fully charged, preventing overcharging, excess heat, and unnecessary battery wear. The fire-resistant PC housing adds an additional layer of safety for overnight use.
