The compact design suits desk or wall-mounted use.

## Long description

BLOW 71-214# is a switching DC power supply that delivers a regulated 5 V output with a maximum current of 3000 mA. The adapter uses a standard barrel connector sized for 2.1/5.5 mm sockets and is designed to provide a stable low-voltage source for small electronic devices. Its compact enclosure allows placement on a desk or installation near wall-mounted equipment, suitable where a reliable 5 V, 3 A supply is required.
Advantages
The switching design ensures efficient energy conversion and reduced heat generation compared with linear adapters. A regulated 5 V output maintains stable voltage under varying loads up to 3 A, which protects connected devices from voltage drift. The commonly used 2.1/5.5 mm barrel connector offers wide compatibility with consumer electronics, routers, LED strips, CCTV cameras and other peripherals. The compact form factor simplifies placement and reduces space requirements.
Suitable for
 Powering routers, modems and network equipment that accept 5 V input
 Supplying LED strips and low-voltage lighting modules rated for 5 V
 Operating CCTV cameras and small surveillance devices requiring up to 3 A
 Powering single-board computers and development boards that use 5 V DC
 Replacing lost or damaged 5 V adapters with a 2.1/5.5 mm barrel connector
Key specifications
 Output voltage: 5 V DC regulated
 Maximum output current: 3000 mA (3 A)
 Connector type: barrel plug compatible with 2.1/5.5 mm sockets
 Converter type: switching (impulse) power supply
 Application: desk or wall-near installation for small electronics
How to use
Connect the barrel plug to the device's 2.1/5.5 mm DC input ensuring correct polarity before powering on. Plug the adapter into a suitable AC mains outlet rated for your region, then switch on the connected device. Verify that the device accepts 5 V and that its current draw does not exceed 3 A to avoid overloading the supply. Allow adequate ventilation around the adapter to maintain safe operating temperature during continuous use.
Usage recommendations
Before use, confirm device voltage and polarity compatibility. Avoid using the adapter in damp or excessively hot environments and do not cover the unit while in operation. For devices with high inrush current or fluctuating loads, ensure the 3 A rating is sufficient; if not, choose a power source with a higher current capacity. Regularly inspect the barrel connector and cable for wear and replace if damaged.
