VFLEX Review: One USB-C Adapter to Replace All Your Clunky Power Supplies

The frustration of managing a growing collection of device-specific power adapters is all too familiar. These adapters clutter your space, often lack clear labeling, and can be difficult to replace if lost. Many rely on proprietary connectors, leaving you at the mercy of questionable eBay sellers offering overpriced OEM or knockoff replacements.

Fortunately, the solution arrives in the form of the VFLEX, a compact USB-C programmable power adapter from Werewolf. This tiny metal dongle eliminates the need for multiple chargers by allowing you to power devices via USB-C, including power banks. The VFLEX features a USB-C female port on one end and a two-prong female connector on the other, designed to attach to interchangeable barrel connectors with varying pitches.

Programming the VFLEX is straightforward. You connect it to your computer or phone, input the required voltage and polarity (critical for safe operation), and save the settings to its non-volatile memory. The device can be configured using either the dedicated app or a web browser. The app provides quick voltage adjustments and an inventory section to track your devices.

The VFLEX also offers advanced functionality. It can communicate with individual power bricks and adapters to measure their output. By entering scanning mode, you can log the output of every USB-C port, creating a library of your adapters, power banks, and devices for easy access. Once configured, the VFLEX can output voltages ranging from 3.3V to 48V, though you’ll need a compatible wall charger to support these levels.

In practical testing, the VFLEX proved its versatility. It successfully powered a Blu-Ray enclosure and drive using a fast-charging power bank, serving as a reliable backup for a lost 12V 2A adapter. However, challenges arose when attempting to power a 24V Zebra label maker via USB-C, highlighting potential limitations with high-voltage devices.
