Introducing VFLEX: The Programmable USB-C Power Delivery Negotiator

Browse the full VFLEX ecosystem here: VFLEX Collection

At ameriDroid, we're excited to spotlight one of the most versatile power solutions: VFLEX. VFLEX is a compact, programmable USB-C Power Delivery (PD) negotiator that lets you easily set and lock in a custom output voltage from any compatible USB-C PD charger or power bank.

In simple terms, VFLEX acts as an intelligent "voltage trigger" for USB-C PD sources. Many devices — especially single-board computers (SBCs) like ODROID, Pine64, Raspberry Pi variants, and other electronics — require specific voltages such as 9V, 12V, 15V, or 20V for optimal performance. Standard USB-C chargers default to 5V unless the device itself negotiates higher voltages. VFLEX solves this by letting you program the exact voltage you need, and it retains that setting even when powered off.

Once programmed, simply connect VFLEX between a PD-capable power source and your device. VFLEX negotiates the desired voltage from the charger/power bank and passes it through reliably, with a built-in green LED to confirm active power delivery.

Key Features & Benefits

• Programmable voltages — Set common PD voltages (5V, 9V, 12V, 15V, 20V, and more depending on your power source).
• Non-volatile memory — Remembers your last setting permanently, no reprogramming needed after power cycles.
• Easy setup — Configure via free mobile app (Android/iOS) or web app in Chrome/Edge.
• Compact & reliable — Small form factor with clear connection status indicators.
• Wide compatibility — Works with virtually any USB-C PD charger or power bank that supports the voltage you select (Amperage is based on what the Power Supply provides at the requested Voltage).

VFLEX is perfect for hobbyists, makers, SBC enthusiasts, and anyone who needs precise voltage control without buying multiple fixed-voltage power supplies.

Getting Started with VFLEX

Requirements

Before you begin, make sure you have:

• A VFLEX Device
• A USB-C cable
• A compatible power supply
• One of the following:
  • Android phone
  • iOS phone
  • Desktop or laptop running Chrome or Edge

Step-by-Step Setup

1. Install or Open the VFLEX App
   Download the VFLEX app for Android or iOS, or visit the web app at https://vflex.app in Chrome or Edge.
   
2. Open the App
   Launch the app on your phone or open the web app in your browser.
3. Connect VFLEX to Your Phone or Computer
   Plug one end of a USB-C cable into VFLEX and the other into your programming device.
   
4. Confirm Connection
   Look for “CONNECTED” with a green dot in the top-left corner. The app will show the current programmed voltage (defaults to 5V).
   
   
5. Change the Output Voltage
   Tap Modify, enter your desired voltage, and hit Save. VFLEX updates instantly.
   
   

You’re ready! Disconnect VFLEX from your programming device, plug it into a PD power source, and connect your target device. The green LED confirms it's delivering your programmed voltage.
