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 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.

The WANPTEK POWER bench power supply offers a solid range for output voltage (0-30V) and current (0-10A), making it versatile enough for many electronics projects and repairs. It has two outputs and includes both USB and Type-C ports, which is handy for charging devices quickly or powering small gadgets alongside your main projects. Its standout feature is the dual coarse and fine adjustment knobs, allowing precise control over voltage and current—great for users who need more accuracy than typical single-knob units. The high-definition four-digit display clearly shows settings, making it easy to read and adjust.

On the safety front, it includes multiple protections such as overcurrent (OCP), short circuit alarms, voltage and power overload safeguards, and overheating protection, which help prevent damage to both the power supply and connected devices. The temperature-controlled fan supports good heat dissipation during extended use. However, the product only has two output connectors, which might limit simultaneous multi-device testing compared to units with more outputs.

This power supply is compact and lightweight, which is handy for bench space. With a 300-watt output, it is powerful enough for many lab and DIY tasks but may fall short for very high-power applications. It suits hobbyists, DIY enthusiasts, and lab users needing a reliable, easy-to-use adjustable power source with good safety features and convenient charging ports. Its precise control knobs and protective functions make it a practical choice, while those needing more outputs or ultra-precise regulation might consider other options.
