Use any USBC Power Delivery (PD) source to run legacy 15V devices without their original adapter. This cable converts USBC PD 15V output into common barrel plug sizes so you can power equipment from a PDcompatible mains adapter or a battery bank. Key benefits Converts USBC PD 15V to multiple standard barrel plugs so older devices can be powered from modern USBC chargers and power banks. Eliminates the need to carry multiple dedicated 15V adapters when traveling or working onsite. Thick, lowresistance wire supports efficiency and low heating for stable power delivery. What it does Input: PDcompatible USBC (TypeC) power source (mains adapter or battery bank). Output: One of the included barrel plugs to match your device. Compatibility and connectors TypeC to barrel connector options: 3.0 x 1.1 mm 3.5 x 1.35 mm 4.0 x 1.7 mm 4.8 x 1.7 mm 5.5 x 2.1 mm 5.5 x 2.5 mm Suitable for various 15V products such as WiFi routers, speakers, LED lights, cameras, printers. Performance and construction Rated for 15V at 3A (45W) maximum. Thicker wire for reduced voltage drop, improved efficiency, and lower operating temperature compared with thinner cables. Designed for reliable DC power delivery from USBC PD sources to barrelplug devices. Practical use scenarios Home backup power: Run a WiFi router from a USBC PD power bank during a power outage to maintain internet access. Field or location shoots: Power LED lights or cameras from a portable USBC PD battery pack when AC power is unavailable. Office flexibility: Use a single USBC PD charger to power a small printer or speaker with the matching barrel plug. What to check before use Confirm your USBC source supports 15V PD output. Match the barrel plug size exactly to your device's power input jack. Ensure your device's power requirement does not exceed 15V/3A (45W). Includes USBC PD input cable with interchangeable/replaceable barrel plug tips in the sizes listed above.
