Please note: This listing is for the VFLEX Base only. An appropriate VFLEX X Connector adaptor cable is required to connect the VFLEX Base to your radio, accessory, or other DC-powered device.

The VFLEX Base is a configurable USB-C Power Delivery output interface designed to let amateur radio operators power compatible DC equipment from a suitable USB-C PD power source.

It can be configured to request an output voltage from 5V to 48V, depending on the capability of your USB-C power supply, mains adaptor, or power bank. This makes it a flexible option for portable radio, QRP operating, shack accessories, test bench use, and field station setups.

Configuration is carried out using the VFLEX app from a phone, tablet, or computer, including iOS, macOS, Android, and web browsers. Once set, the configuration is stored in the device’s memory, so VFLEX can automatically negotiate the selected voltage whenever it is connected to a compatible USB-C Power Delivery source.

The VFLEX Base features rugged anodised aluminium and ABS construction, an RGB LED status indicator, and an X Connector output interface capable of up to 5A output. With the correct adaptor cable, it can be used with a wide range of radio accessories, DC equipment, and portable station devices.

Important Note

VFLEX is not a power supply by itself. It negotiates power from a compatible USB-C Power Delivery source, so the available voltage and current will depend on the power supply, cable, and selected VFLEX configuration.

Please check the voltage, current draw, and polarity requirements of your radio or accessory before connecting. Incorrect voltage or polarity may damage connected equipment.

Output adaptor cables, USB-C power sources, and connected radio equipment are sold separately unless otherwise stated.
