Power Adapter GENWAY 12V 1A 5.5mm — Switch-Mode DC Power Supply

GENWAY 12V 1A 5.5mm switch-mode power adapter supplies regulated 12 volts DC at up to 1 ampere through a standard 5.5 mm barrel connector. The compact SMPS design delivers a steady low-power supply suitable for small electronic devices and fixtures that require a constant 12V input. Built for continuous operation, this adapter provides stable voltage with basic protections against overload and short-term fluctuations common in everyday use.

Advantages

The adapter’s switch-mode topology ensures efficient power conversion and reduced heat compared with linear supplies, allowing a smaller, lighter housing. A standard 5.5 mm barrel output fits many consumer and industrial devices, while the regulated 12V output maintains consistent performance under typical load conditions up to 1A. The compact form factor is convenient for installations with limited space and for portable setups.

Suitable for

• Home and small office routers and modems requiring 12V DC
• Surveillance cameras and networked camera modules with 5.5 mm barrel inputs
• Low-power LED strips and under-cabinet lighting with 12V rating
• Small appliances and electronic modules that list 12V/1A as acceptable power

Key specifications

• Output voltage: 12 V DC regulated
• Maximum output current: 1 A
• Output connector: 5.5 mm barrel (outer diameter 5.5 mm)
• Power supply type: switch-mode (SMPS)
• Form factor: compact wall/desktop adapter
• Typical use: continuous low-power supply for small electronics

How to use

Confirm that your device requires a 12V DC input and that the current draw does not exceed 1A. Check the polarity of the barrel connector to match the device’s jack before connecting. Plug the adapter into a compatible mains outlet, then insert the barrel connector into the device’s power socket. Allow the adapter to settle for a moment after connection; the regulated output should provide a stable 12V supply during operation. Disconnect from mains before performing maintenance on the powered device.

Usage recommendations

Use in a well-ventilated area and avoid covering the adapter to prevent heat buildup. For devices drawing close to 1A, verify connector fit and monitor for excessive heating. Do not use with devices that require higher current or a different voltage. In case of signs of malfunction (noise, unusual heat, or smell), disconnect immediately and replace the adapter.
