Portable 9 V and 12 V boost cable

The KEHIPI 2001708001 converts a standard USB 5 V source into selectable 9 V or 12 V DC output. It targets users who need to run 9 V or 12 V devices from a power bank or USB charger. Maximum output is 1 A at 9 V and 0.8 A at 12 V.

Replaces a dedicated wall wart

This adapter removes the need for a separate mains power supply when a USB port or power bank is available. The step-up is worthwhile when the load stays within the 1 A or 0.8 A limits and the device uses a 3.5 mm × 1.35 mm barrel jack.

Plug-and-play with a selector switch

A slide switch chooses 9 V or 12 V and an LED display confirms the setting. The 0.8 m cable ends in a USB-A plug and the included 3.5 mm × 1.35 mm connector fits the device. Wrong voltage selection or loads above the rated current will cause shutdown or unstable operation.

Questions about this item

What size DC barrel jack does the included 3.5 * 1.35mm connector fit?

The supplied connector has a 3.5 mm outer diameter and a 1.35 mm centre pin, matching devices that use that exact barrel size.

How do I select 9 V or 12 V output on the built-in switch, and what confirms the setting?

Slide the switch to the desired position; the LED display immediately shows the chosen output voltage so you can verify it before connecting your device.

When should I replace the USB step-up converter cable if I use it regularly with a power bank?

Replace it if the LED display flickers, the output voltage drops under load, or the 0.8 m cable sheath shows cracking or exposed wires.
