Power adapter cable for 5 V micro-USB devices

This 15-centimetre cord converts a DC 5.5 mm × 2.1 mm female barrel jack into a micro-USB male plug. It lets you run LED desk lamps, small fans or other 5 V micro-USB gear from an existing DC power supply. The cable is rated for up to 3 A and uses 22 AWG pure copper conductors for stable current delivery. Two pieces are included in the pack.

Replaces bulky AC-to-DC wall warts

Instead of a dedicated mains adapter, you can feed power from a compatible DC source through this short extension. The jump is worthwhile when you already have a 5 V DC supply with a 5.5 mm × 2.1 mm output and want a tidy, portable way to reach micro-USB devices. Each cord weighs only 10 g and adds minimal clutter to a backpack or laptop bag.

Limited to power-only at 5 V and 3 A

The micro-USB end carries no data lines, so it cannot sync or communicate with host devices. Voltage is fixed at 5 V and current must not exceed 3 A, ruling out higher-power peripherals. Polarity follows the centre-positive 5521 barrel standard, so the source must match that configuration. Length is fixed at 15 cm, restricting placement flexibility.

Questions about this item

What size DC barrel jack does the 5.5mm × 2.1mm female connector fit?

The female end accepts a standard 5.5 mm outer-diameter, 2.1 mm inner-diameter DC plug, often labelled 5521.

Which end do I plug into the power source and which into the device?

Connect the DC 5521 female side to your 5 V power supply, then plug the Micro USB male end into the device; the cable only delivers power, not data.

How long before the 22 AWG copper conductors might need replacement?

With normal low-power use at 5 V / 3 A the pure-copper 22 AWG wires should last years; replace if the PVC jacket cracks or the connectors become loose.
