USB 5V to 12V step-up converter cable

This cable integrates a boost module that raises standard USB 5V power to 12V DC for low-current devices. It accepts input from USB chargers, laptop ports or power banks. The three-foot length offers flexible placement for compact 12V electronics such as LED strips, small cameras or mini routers.

Dual 5.5mm barrel plugs for wider compatibility

The cable terminates in a universal DC jack that fits both 5.5x2.1mm and 5.5x2.5mm sockets, removing plug-mismatch concerns. Output current is limited to low-power loads; exceeding the rated load causes overheating and permanent module damage. High-power equipment cannot be supported.

Replaces bulky 12V wall adapters for portable setups

The all-in-one design eliminates a separate converter brick, making it convenient for travel or temporary power scenarios. The jump is worthwhile when a lightweight USB-powered solution is preferred and the connected device draws minimal current within the cable’s low-load rating.

Questions about this item

Which DC barrel size should I pick — 5.5×2.1 mm or 5.5×2.5 mm?

The cable includes both 5.5×2.1 mm and 5.5×2.5 mm plugs on the same connector, so it fits either jack without choosing.

What does the 12 V output mean when I plug this into a USB port?

The built-in boost module raises the USB 5 V supply to a steady 12 V DC, letting low-current 12 V gear run from a charger, laptop or power bank.

What USB standard does the input use and what current limit applies?

It draws power from any standard USB-A port; the notice warns that the device current must stay within the rated load or the module will overheat and fail.
