Original Huawei 12V 1A Power Adapter – Model HW-120100U1W | UL Certified Power Supply | 5.5mm Connector
Don’t risk your expensive electronics with low-quality generic chargers. This Original Huawei 12V 1A Power Adapter is the official power supply designed for 24/7 operation without overheating or voltage drops. Manufactured for Huawei by UE Electronic, it meets the strictest global safety standards (UL, NOM, CE).
Precision Engineering
This adapter features an intelligent switching circuit that protects against voltage spikes and short circuits. Its exterior has an elegant diamond-textured finish that is both durable and scratch-resistant. It is a superior technical choice for powering devices sensitive to electrical noise, such as audio equipment, security cameras, and internet modems.
Connector Compatibility (Technical Detail)
The output connector features a 5.5 mm outer diameter with a tuning-fork style internal contact. Although the standard inner pin size is 2.1 mm, your 2.2 mm measurement confirms that the internal spring mechanism allows a secure and firm fit across a wide range of devices with center pins from 2.1 mm to 2.5 mm, helping prevent accidental disconnection.

(FAQ)
Q: Is it compatible with other brands’ modems (e.g., TP-Link or Tenda)?
A: Yes. Although it is a Huawei-branded adapter, the 12V voltage and 1A current are industry standards. If your device requires 12V and up to 1A (or less, such as 0.5A) and the connector fits, it will work properly.
Q: What does “OEM Bulk” mean?
A: It means the product is new and original but comes from industrial bulk batches intended for installers or system integrators. It does not include retail packaging, which allows for a better price. The unit is guaranteed new and fully functional.
Q: My device requires 12V 0.5A. Can I use this 1A adapter?
A: Yes. The Huawei 12V 1A adapter provides more current capacity than required. Your device will only draw the 0.5A it needs, allowing the adapter to run cooler and potentially last longer. You should never use an adapter with a lower current rating than required.
Q: Is it suitable for security cameras?
A: Yes, it is excellent for CCTV cameras. As a certified high-frequency switching power supply, it delivers a stable output that helps prevent video noise, interference, or image distortion often caused by low-quality adapters.
