Innovative Bench Power Supply with No Inductor Technology - PocketPD

Traditional power delivery systems often come with set voltage and current outputs, leading to frustration for users needing more flexibility. Pocket PD addresses these issues by providing high-resolution voltage outputs and customizable current limits.


PocketPD - USB-C Portable Bench Power Supply

The inspiration behind Pocket PD stemmed from the common frustrations associated with traditional power delivery systems. Users often found themselves constrained by fixed voltage and current outputs, which limited their flexibility and control. This need for a more adaptable solution led to the development of Pocket PD, aimed at providing a user-friendly, high-resolution power delivery tool.


Pocket PD's journey began with the creation of the first version, Poopd, designed for Raspberry Pi. This initial prototype served as a proof of concept, demonstrating the feasibility of adjustable power delivery. Through rigorous testing and iterative improvements, the team enhanced the device's capabilities, eventually integrating both voltage and current control into a single, compact unit. This evolution resulted in a versatile and efficient power delivery solution that meets the diverse needs of makers and electronics enthusiasts.

Features of Pocket PD

Pocket PD empowers users with the ability to achieve precise voltage settings using a standard power brick. This high-resolution control allows for fine-tuning of voltage outputs, catering to specific project requirements and enhancing the overall flexibility of power delivery.

The device also enables users to set specific current limits, significantly improving the usability and safety of power delivery. By customizing current outputs, users can ensure that their devices receive the appropriate amount of power without the risk of overloading or damage.

One of the standout features of Pocket PD is the integration of both voltage and current control into a single device. This combination makes it incredibly versatile and user-friendly, providing comprehensive control over power delivery in one compact unit.

Practical Demonstration

One practical use case for Pocket PD is charging a LiPo battery that requires specific voltage and current settings. Typically, such batteries need a dedicated charger, but Pocket PD simplifies this process using a regular power bank.
