Portable small adjustable power supply

These devices provide stable, adjustable power outputs in a portable form factor, making them ideal for various applications, from prototyping circuits to powering small gadgets. They are especially useful when fixed-voltage power supplies—such as those from old laptops, power banks, or other power adapters—are already available.

Compact power supplies are becoming increasingly popular among electronics enthusiasts, makers, and professionals. These devices provide stable, adjustable power outputs in a portable form factor, making them ideal for various applications, from prototyping circuits to powering small gadgets.

This variable DC power supply is a very stable, regulated DC power supply. It has the characteristics of low ripple and noise, high accuracy, high reliability, perfect overload and short circuit protection circuits, and it is especially suitable for laboratory, school and electronic maintenance. Designed for laboratory and industrial use.

Equipped with 5V 2A charging port which can quick charge your devices. Due to the use of a more compact circuit board, this DC regulated power supply is also more compact under the conditions of richer functions and higher accuracy, the performance is beyond linear power supply.

A portable USB power bank (5 V, 2 A) transforms into a versatile power supply, offering a 0-5 V adjustable output, including the frequently needed 3.3 V for microcontrollers like the ESP32. Some power banks also provide 12 V outputs with up to 10 A, making the DPS-150 even more versatile.

To provide the input voltage (5 – 32V) required for the DPS-150, several power supply options are available: This power adapter, included in the DPS-150PD kit, offers the following features: A key advantage of the DPS-150 is its wide input voltage range, allowing it to work with various power sources.
