Desktop power supply QOLTEC 50798, 120W, 12V 10A

QOLTEC 50798 is a desktop power supply providing a stable 120W DC output at 12V and 10A. It is made for powering a range of 12V electronic devices such as routers, LED strips, CCTV cameras and other small equipment that require continuous, regulated DC power. The compact desktop form factor allows placement next to devices in home, office or light commercial setups and includes protections commonly expected from modern adapters.

Advantages

The unit delivers a constant 12V output with a rated 10A current, supporting devices that need up to 120W of power. Its desktop design makes installation and access simple without occupying internal device space. Built-in protection features help reduce risks from overload, short circuit or voltage fluctuations, improving operational reliability. The adapter’s efficiency and thermal characteristics are suitable for continuous use in typical indoor environments.

Suitable for

• Powering routers, network switches and modems
• LED strip installations and lighting controllers
• CCTV cameras and small surveillance systems
• Small desktop appliances and electronic projects requiring 12V/10A

Key specifications

• Output voltage: 12V DC
• Maximum output current: 10A
• Maximum output power: 120W
• Form factor: desktop/ external power supply
• Intended use: continuous indoor DC powering of electronic devices

How to use

Connect the power supply to a mains outlet using the included cable, observe the correct input voltage for your region, then attach the adapter’s DC output connector to the device requiring 12V power. Ensure polarity matches the device’s connector requirements and that the connected device’s current draw does not exceed 10A. Place the unit on a stable, ventilated surface away from direct heat sources and moisture. After connection, verify device operation and periodically inspect the adapter and cables for signs of wear.

Usage recommendations

Use the power supply indoors in a dry, well-ventilated location. Avoid using extension cords or connectors that could introduce excessive resistance. If the connected device regularly approaches the 10A limit, allow additional cooling clearance and consider a higher-rated supply. Disconnect the adapter during thunderstorms or extended periods of non-use to reduce risk from mains disturbances.
