Frequently Asked Questions

Q: What devices is this USB Type-C power supply transformer compatible with?

A: This AC-to-DC 5V transformer is compatible with any device that requires a stable 5V DC power input, including compact surveillance cameras, WiFi monitoring equipment, smart home sensors, IoT modules, Raspberry Pi boards, and other USB-powered electronics rated at 1A or 2A.

Q: Can I use this power supply transformer in countries other than China?

A: Yes. The transformer accepts a wide AC input range of 100V–240V, making it suitable for use in most countries around the world. Please note that the physical plug type may vary by region, so you may need a plug adapter depending on your local wall socket standard.

Q: What safety protections does this power transformer include?

A: The HELTC power supply transformer features built-in overload protection and overheating protection. These dual safety mechanisms help prevent damage to both the transformer and your connected devices during prolonged or heavy-duty use, giving you peace of mind in everyday operation.

Q: What does the 95% efficiency rating mean for my electricity bill?

A: A 95% conversion efficiency means that 95% of the electrical energy drawn from the wall is successfully converted to usable DC output, with only 5% lost as heat. This high efficiency rating translates to lower energy waste, reduced heat generation, and a smaller impact on your electricity costs compared to less efficient adapters.
