Power-bank backup for routers

This cable converts a standard USB-A power-bank output into a 5.5 mm × 2.1 mm DC barrel plug, letting you keep a router running during a mains outage. It also powers 5 V accessories such as small fans, lights or speakers directly from the same bank. The micro-USB input end plugs into any 5 V USB-A port without extra adapters.

Fixed-voltage boost versions

Three distinct cable models are offered: a 5 V pass-through, a 9 V boost, and a 12 V boost, each with the boost circuitry built into the connector housing. The 9 V and 12 V variants deliver .8 to 1 A, so they suit devices rated at or below that current. Choose the version that matches the voltage printed on the target device’s label.

Simple inline integration

No external power supply or configuration is required; the cable draws 5 V from the power bank and presents the selected voltage at the barrel jack. It adds no bulky module to the chain, leaving USB ports free for other peripherals. Builders needing adjustable voltage or currents above 1 A will need a separate solution.
