10 Best Bench Power Supply 2025 in the United States

The Jesverty DC Power Supply is designed for those needing a reliable and adjustable power source, especially in lab environments or for hobby projects. With an output voltage range of 0-30V and a current range of 0-10A, it meets the basic requirements for many applications. One of its standout features is the 4-digit LED display, providing precise readings for voltage, current, and power, which is great for monitoring performance in real-time.

The unit's ability to automatically switch between constant voltage (C.V.) and constant current (C.C.) modes based on load changes adds to its versatility, making it suitable for various testing scenarios. Its compact size and lightweight nature allow for easy portability and space-saving on your workbench.

Safety is a major strength as well; it offers multiple protection features, including short-circuit protection and overload protection, which enhances reliability and extends the product's lifespan. Additionally, the inclusion of a 5V/2A USB port is a nice touch for charging smaller devices.

There are some considerations to keep in mind. While the provided test leads are a bonus, they might not be sufficient for high current applications, so users may need to invest in higher-rated leads for demanding projects. The product's relatively simple interface may not provide advanced features found in higher-end models, which might limit its use for experienced users seeking detailed control.

The NANKADF 30V 10A bench power supply is a versatile tool suitable for various electronic testing and repair tasks. It features a high-precision encoder adjustment knob, allowing you to set voltage and current accurately and easily. The output enable/disable button is a thoughtful inclusion, preventing potential damage to connected devices by ensuring you can quickly stop the output if necessary. Safety is further enhanced with an overcurrent protection feature that stops output and alerts you in case of a short circuit, safeguarding both the power supply and your devices.

The 4-digit LED display is clear and precise, showing real-time voltage and current readings down to 0.01V and 0.001A, respectively. It also includes a USB fast-charging port, making it convenient for charging other devices during use. Compact and lightweight, this power supply is easy to carry and saves space on your workbench.

However, it may fall short for users needing more than one output or higher current and voltage ranges. Additionally, while the display is accurate, some might prefer a more advanced graphical interface. This bench power supply is well-regarded for its reliability and functionality.

The Jesverty SPS-3010V is a versatile bench power supply designed for those who need precise control over voltage and current. An upgrade from traditional knobs, it features coarse and fine encoder knobs for accurate adjustments. This makes it ideal for settings where precise power control is essential, such as laboratories, educational sites, and electronic DIY projects. The device offers a wide range of output voltage (0-32V) and current (0-10A), making it suitable for various applications.

Additionally, it includes USB-A and USB-C ports with 20W quick-charge capability, a convenient feature for charging devices and powering small projects simultaneously. The 4-digit LED display provides clear readings, ensuring you can monitor settings with ease. An added output ON/OFF button enhances user convenience by allowing easy control without disconnecting the load. Despite its compact size and lightweight design, the SPS-3010V is packed with protective features such as over-current protection (OCP) and a temperature-regulated cooling fan, enhancing safety and durability.

Some users may find the need for higher-quality test leads, as the included ones might not suffice for long-term high-current use. Also, the OPN function, which automatically starts output upon powering on, may require careful handling to avoid accidental outputs. The power supply's compact form factor saves space on your workbench, but its lightweight build might lead to concerns about its stability during use. The Jesverty SPS-3010V is well-regarded for its performance and reliability, making it a strong choice for those in need of a dependable bench power supply.
