Ditch powerbricks, level-shifters and adaptors for life. Run all your devices via this compact & precise USB Power Supply.

Runs off anything USB (USB-C/USB-A/MicroUSB) and outputs 0 - 30V @ 0 - 2A.


The Lab401 Pocket USB Power Supply is an invaluable device for every hacker's toolkit. Forget fumbling with level convertors every time you're looking to power your microcontroller, or digging through 'that' box of adaptors when you need 12 volts.

Not everyone has the luxury of a fully equipped lab - and when we're in the field, size matters. The Pocket USB Power Supply takes in 4 - 30V via USB-C, USB-A, MicroUSB (and even terminals..) and supplies 0 - 30V at 0 - 2A.

It has an adjustment resolution of 0.01V and 0.001A (1mA) - allowing for precise control of almost any device hackers and pentesters need to use.

Inexpensive, compact and tested by Lab401 as a must-have device.

Hands on with the Pocket USB Power Supply

In this episode, we get hands on with the Pocket USB Power Supply and the EMUTAG, a Mifare Ultralight Emulator. The EMUTAG has a fairly obtuse battery and power requirements, so we're using the USB Pocket Power Supply to get the device powered up.

We go over the product basics, including input and output types, configuration of the device, and ultimately - how to do something useful with it.
