USB 2.0 A to 90° 5.5x2.1mm Barrel Power Cable

This two-pack of USB 2.0 Type-A male to right-angled 5.5 x 2.1 mm DC barrel jack cables supplies 5 V power from any standard USB-A port. Each cable measures 3 ft and is rated for a maximum of 2.5 A, making it suitable for low-voltage peripherals that accept a centre-positive barrel connector. The 90-degree plug reduces strain in tight spaces behind desks or enclosures. Molded strain relief on both ends helps withstand repeated insertion and routing.

Check your device polarity

Verify that the equipment you intend to power uses a centre-positive 5.5 mm outer and 2.1 mm inner barrel jack and operates at 5 V DC. The USB-A source must be able to deliver the required current up to 2.5 A; some laptop ports or unpowered hubs may limit output to less than that. Confirm the cable length of 3 ft reaches from your USB port to the device without tension. No driver installation is needed, but the host port must remain powered while the peripheral is in use.

Sustained load stays within the 2.5 A rating

Under continuous operation the 24 AWG conductors carry up to the rated 2.5 A without exceeding the cable's thermal limits, provided the USB host maintains a stable 5 V output. The right-angled barrel plug maintains a secure connection even when the device is moved slightly, reducing intermittent contact that can cause voltage dips. Molded connectors prevent wire fatigue at the solder joints during long-term stationary use. The two-pack allows one cable to remain at a desk while the other travels with a laptop bag.

Questions about this item

What comes in the box and do I need to buy a USB power source separately?

The pack contains two black USB Type A male to 90° 5.5 × 2.1 mm barrel cables, each 3 ft long. You will need a USB port or charger that can supply 5 V at up to 2.5 A.

Both cables are identical, so how do I decide which to use where?

Each cable is the same 24 AWG, 5 V, 2.5 A design with a right-angled barrel plug; choose based on which device needs the angled connector for a tighter fit.

What does the 2.5 A rating mean when I plug this into my laptop USB port?

The cable can carry up to 2.5 A at 5 V, but the actual current is limited by the USB port you use — many laptop ports provide less, so check your port's output before powering a device that draws the full 2.5 A.
