Product information

Description

QOLTEC PREMIUM power adapter provides a compact, plug-in power solution with 15W output, delivering 15V at 1A through a standard 5.5×2.1 mm DC plug. Intended for use with portable devices and equipment that require a stable 15V/1A supply, this adapter converts mains voltage to a regulated DC output suitable for home and office environments. The unit is branded QOLTEC and designed for straightforward connection where a 5.5×2.1 mm barrel connector is specified.

Advantages

The adapter offers a stable 15V output with a maximum power of 15W and a current rating of 1A, providing consistent operation for compatible devices. Its 5.5×2.1 mm DC plug matches a wide range of consumer and professional equipment. The compact plug-in design conserves space and simplifies installation, while the regulated output supports reliable charging and continued device operation under normal load conditions.

Suitable for

  • Powering portable electronics and accessories requiring 15V/1A input
  • Replacement adapter for devices with a 5.5×2.1 mm DC barrel socket
  • Home and office equipment such as small routers, network devices, and certain audio components

Key specifications

  • Output voltage: 15V DC
  • Output current: 1A
  • Connector type: 5.5×2.1 mm DC barrel plug
  • Form factor: plug-in mains adapter

How to use

Ensure the target device requires a 15V DC supply and accepts a 5.5×2.1 mm barrel connector. Verify polarity matching between adapter and device. Insert the DC plug into the device socket and connect the adapter to a compatible mains outlet. After connection, confirm the device powers or charges as expected. Disconnect from mains before removing the plug and avoid twisting or bending the connector while in use.

Usage recommendations

Use the adapter in dry, indoor environments and avoid exposure to moisture or extreme temperatures. Confirm device compatibility with 15V/1A power and the 5.5×2.1 mm connector before use.
