Versatile 8-in-1 USB power cable

This new cable converts a standard 5 V USB 2.0 port into a 5.5 × 2.1 mm DC output and includes eight interchangeable barrel connectors. It is built for hobbyists and technicians who power 5 V gear such as LED pixel hubs, cameras, tablets, routers, VoIP phones, DJ controllers or webcams from a USB source.

Suited for multi-device 5 V setups

The assortment covers plug sizes from 3.5 × 1.35 mm up to 6.4 × 4.4 mm, so one cable replaces a drawer full of dedicated adapters. Builders who need 9 V, 12 V or higher-voltage rails, or who require a locking connector, should look at a different solution.

Limited to 5 V 3 A from the USB host

The USB 2.0 male plug can deliver no more than 5 V at 3 A, regardless of the tip fitted. Any device that draws more current or expects a higher voltage will not operate correctly from this adapter.

Questions about this item

How much heat or noise does the 5V USB 2.0 cable produce when powering devices continuously?

The cable has no moving parts or active components, so it generates no audible noise and only minimal warmth from normal resistance during extended use.

Which power source must I already have to use the USB male plug on this adapter?

You need any standard 5V USB Type-A port such as a wall charger, power bank, or computer port that can supply up to 3A for the cable’s maximum rated load.

Will the included 5.5×2.1mm and seven other DC tips fit the older 5V router and LED hub I still use?

The set provides tips sized 6.4×4.4mm, 6.3×3.0mm, 5.5×2.5mm, 5.5×2.1mm, 5.5×1.7mm, 4.8×1.7mm, 4.0×1.7mm and 3.5×1.35mm, covering the barrel connectors commonly found on legacy 5V networking and lighting gear.
