USB to DC Power Cable with USB-A to Type M Barrel Plug Connection
You don’t need to carry around a wall adapter to keep your 5V DC mobile device charged. This USB to 5V DC power cable features a male USB-A plug for connecting to a computer USB port and a male 5.5 mm (OD) x 2.1 mm (ID) Type M barrel plug for connecting to a mobile device. The U152-003-M is ideal for powering and/or charging a compatible security camera, switch, router, external hard drive, media player or other mobile device. Its three-foot length makes it convenient to carry in your backpack or laptop bag, instead of dragging around each mobile device’s wall charger. Polarity: positive tip, negative sleeve.
