⚡ At a Glance
- • Power Output: Regulated 5V DC at 2A (10W) for consistent operation
- • Best for: LED strips, CCTV cameras, wireless routers and small speakers
- • Not ideal for: Devices that require higher voltage or currents above 2A
Converts 100–240V AC to a steady 5V DC output at 2A with a 5.5mm x 2.5mm plug. Includes a 1m cable and multiple built-in safety protections.
Wide device compatibility, with universal AC input and standard plug
Switching converter accepts 100–240V AC at 50/60Hz and outputs a regulated 5V DC through a 5.5mm x 2.5mm DC plug. The 1m cable fits typical installations without extra extension.
Suitable for a variety of low-power electronics such as LED strips, CCTV cameras, routers and speakers. Fewer adapter swaps are needed thanks to the common connector and wide input range.
Safer operation, with multiple built-in protections
Protection systems cover undervoltage, overvoltage, short circuit, overcurrent and over-temperature, while an outer shell uses fireproof material. The switching architecture helps maintain stable output under varying mains conditions.
Reduced risk of damage to connected equipment and lower chance of overheating during extended use. Suitable where continuous, protected power is important.
Stable performance, with regulated 5V output
Regulation circuitry maintains a steady 5V DC, delivering up to 2A (10W) to connected devices. The design prevents noticeable voltage fluctuations under normal loads.
Connected devices run reliably without brownouts or erratic behaviour. Ideal for installations where consistent operation matters, such as CCTV or network kit.
