Frequently Asked Questions

Q: What devices can I charge with this USB power module?

A: This USB power module outputs a stable 5V DC supply, making it compatible with virtually all USB-charged devices including smartphones, tablets, Bluetooth earphones, portable speakers, and other 5V USB accessories. The 2.1A variant is especially suitable for tablets and faster-charging smartphones.

Q: Is this USB charger module safe to install in a wall socket enclosure?

A: Yes. The module uses a switch-mode power supply design that operates efficiently and generates minimal heat. Its output is below 50V AC / 75V DC, meeting EU Low Voltage Directive (LVD) requirements. However, installation should always be performed by a qualified electrician, as the input side connects to 220–240V mains voltage.

Q: What is the difference between the 1A and 2.1A output versions?

A: The 1A version is suitable for standard smartphones and smaller USB devices, while the 2.1A version provides higher current output for tablets, newer smartphones with higher charging demands, or devices that benefit from a faster charge rate. Choose based on the maximum current requirement of your intended device.

Q: Can this module be used in countries with 110V mains power?

A: No. This module is designed for 220–240V AC mains input only. It is not suitable for use in 110V electrical systems (such as those in the USA, Canada, or Japan) without a step-up transformer.
