Four-cable step-up set

The KEHIPI pack contains four USB-to-DC cables that raise a 5 V supply to 12 V for low-power devices. Each cable ends in a 5.5 mm by 2.1 mm barrel plug and measures 1 M in length. They suit users who need to run routers, fans, speakers or similar gear from a standard USB port.

Copper conductors and barrel plugs

High-quality copper wire carries the converted current while a built-in smart IC chip provides overcurrent, overvoltage, overload and short-circuit protection. The USB-A male plug requires a 5 V 2 A source; lower-current ports may not start the connected equipment. The fixed 5.5 mm by 2.1 mm connector fits only jacks of that exact size.

Limited to low-draw 12 V loads

The step-up design cannot support high-current equipment, so devices such as large monitors or motor-driven appliances are unsuitable. Buyers who need more than the available output current or a different barrel diameter must choose another solution. The 3.2 ft cable length also restricts placement to within reach of the USB power source.

Questions about this item

What output voltage does the USB 5V to 12V step-up cable deliver?

The cable converts a USB 5 V input to a regulated 12 V DC output through the 5.5×2.1 mm barrel connector.

What barrel-plug size must my device accept for this cable to fit?

The cable terminates in a 5.5 mm outer diameter by 2.1 mm inner diameter male DC plug.

How do I connect the four cables so each device powers on reliably?

Plug each USB-A end into a port or charger that can supply at least 2 A at 5 V; the built-in boost IC will not start if the source current is lower.
