DC Power Supply Bench Variable Power Supply with Encoder Knob

In this review of the DC Power Supply from WANPTEK POWER, the bottom line is straightforward: it is a budget-minded bench supply that delivers accurate, stable outputs and useful modern conveniences for hobbyists and bench technicians. The combination of a high-definition four-digit display, coarse and fine encoder knobs, and a dedicated TYPE-C fast-charging port makes it especially valuable for electronics repair, testing motors and prototyping where quick, repeatable adjustments matter.

Key Features

• Coarse and Fine Coding Knob: Two separate encoder knobs let the user set the integer and fractional parts of voltage independently for faster, more precise adjustments.
• Wide Output Range: Adjustable output up to 60V and 5A covers a broad range of bench tasks from low-voltage electronics to small motor testing.
• USB and Type-C Quick-Charge: The dedicated 5V/3.6A Type-C port provides fast charging for devices or powering DUTs without tying up the main output channels.
• Overcurrent and Short-Circuit Protection: Built-in OCP with audible short-circuit alarm and multiple protections prevents damage and notifies the operator quickly.
• Clear Display: A high-definition four-digit display makes it easy to read setpoints and measured values at a glance, improving workflow on the bench.
• Thermal Management: An intelligent temperature-controlled fan and heatsink keep the unit stable under load during extended use.

Who It's For

The WANPTEK DC power supply suits hobbyists, bench technicians and small lab environments that need a capable, economical regulated supply with modern conveniences like a Type-C port and precise encoder control. Its combination of features works well for electronics repair, education labs and product development where repeatable voltage and current settings save time.

Those who need ultra-low noise or specialist laboratory certification should look elsewhere, since this unit targets practical versatility and value rather than laboratory-grade noise floors or calibrated metrology use.

Pros & Cons

Pros

• Practical dual encoder knobs give fast, accurate voltage setting for repeatable results.
• Useful 5V/3.6A TYPE-C quick-charge port frees the main output for the device under test.
• Multiple safety protections including OCP, grounding and thermal control improve everyday safety on the bench.
• High-definition four-digit display and audible alarms make monitoring simple and clear.

Cons

• The key beep and audible short-circuit buzzer are loud; some users may find the beep intrusive though it can be muted.
