AC charger blue star TFK-TC-1100B 1 A — single-port USB power adapter

Blue Star TFK-TC-1100B is a compact AC charger that provides a stable 5 V output with 1 A current through a single USB port. The adapter converts household mains voltage to a USB power supply suitable for charging phones, basic mobile devices, wireless earphones, fitness trackers and other small USB-powered accessories. Its small form factor is intended for everyday use at home, in the office or while travelling when only standard charging speed is required.

How to use

Insert the charger into a compatible AC mains outlet and connect a USB cable between the charger and your device. Ensure the device accepts 5 V/1 A charging; devices that require higher current or specific fast-charge protocols will charge more slowly or may not initiate fast charging. Monitor the device temperature during initial use; disconnect once charging is complete or if the adapter or device becomes unusually warm.

Usage recommendations

Use a quality USB cable in good condition and avoid exposure to moisture or extreme temperatures. For devices that support fast charging, use an appropriate higher-output charger. Unplug the adapter when not in use to reduce standby power consumption.
