USB 2.0 barrel power cable

This LORDWORLD cable converts a USB 2.0 port into a 5 V DC supply through a 5.5 mm by 2.1 mm barrel connector. It targets owners of small electronics that draw power from that specific jack size. The 100 cm length gives flexibility for desk or bench setups.

Direct 5 V output for compatible devices

The cable delivers 5 V DC directly from the USB source to the barrel plug without additional regulation. Devices expecting that exact voltage and connector can operate from any standard USB 2.0 port. No software or driver installation is involved.

Limited to USB 2.0 current capability

The USB 2.0 interface restricts available current to the port's rated maximum, so higher-draw equipment will not start or may shut down. The fixed 5.5 mm by 2.1 mm barrel polarity suits only matching inputs. Buyers whose gear needs a different voltage, a larger jack or more current cannot use this cable.

Questions about this item

Does the 5.5 mm × 2.1 mm barrel connector wear out after repeated plugging?

The barrel plug is a passive metal contact; it has no moving parts that degrade, so normal insertion cycles do not shorten its life.

What limits the cable when I draw the maximum current my USB 2.0 port can supply?

The thin conductors and 100 cm length add resistance, so voltage drop at the device becomes the first bottleneck under sustained load.

Will the cable get warm if I leave a 5 V device running all day?

Only a slight warmth is normal; the cable carries whatever current the USB 2.0 host allows and has no active components to generate extra heat.
