1. DC Power Supply Variable
- Brand: Jesverty
- Manufacturer: Jesverty
The Jesverty SPS-3010 offers a well-rounded set of features, including a high-precision 4-digit LED display and automatic constant voltage (CV) and constant current (CC) modes. Its compact design makes it ideal for small workspaces, while its safety features, such as over-current and short-circuit protection, ensure reliable operation. The inclusion of a 5V/2A USB port adds versatility for charging devices during testing.
Performance-wise, the SPS-3010 excels in delivering stable output with minimal noise and ripple, making it suitable for sensitive electronic applications. However, the test leads provided are not ideal for high-current applications, requiring users to invest in higher-capacity leads for prolonged use. The automatic CV/CC switching is seamless, but beginners may need time to understand the crossover point settings.
Pros
- High-precision 4-digit LED display
- Compact and lightweight design
- Reliable safety features (short-circuit and overload protection)
- Automatic CV/CC mode switching
- Affordable price point
Cons
- Test leads are not suitable for high-current applications
- Limited input voltage compatibility (no 220V support)
2. DC Power Supply Variable
- Brand: Jesverty
- Manufacturer: Jesverty
The Jesverty SPS-3010V is the premium option in this lineup, featuring upgraded encoder knobs for coarse and fine adjustments, as well as dual USB-A and USB-C ports supporting 20W fast charging. The added output ON/OFF button simplifies operation, reducing the need to disconnect the load for adjustments. Its compact design and lightweight build make it portable and space-efficient.
In testing, the SPS-3010V demonstrated exceptional precision and user-friendly controls, making it ideal for professional applications. The dual fast-charging ports are a standout feature, especially for users working with modern electronics like Raspberry Pi or Arduino boards. However, the higher price point and slightly heavier weight compared to other models may deter budget-conscious buyers.
Pros
- Encoder knobs for precise adjustments
- Dual USB-A and USB-C fast-charging ports
- Output ON/OFF button for convenience
- Compact and lightweight design
- Wide input voltage compatibility (115V/230V)
Cons
- Higher price point
- Slightly heavier than other models
3. DC Power Supply Variable
- Brand: NANKADF
- Manufacturer: NANKADF
The NANKADF bench power supply offers a precise encoder knob for custom voltage and current settings, along with an output enable/disable button for added safety. Its 18W USB fast-charging port is a useful addition for charging devices during operation. The compact design and lightweight build make it a practical choice for portable use.
While the NANKADF power supply performs well under typical loads, the lack of Type-C charging and slightly lower USB charging power (18W) compared to competitors limits its versatility. The short-circuit alarm is a valuable feature for protecting sensitive equipment, but the display brightness adjustment could be improved for better visibility in varying lighting conditions.
Pros
- Precise encoder knob for custom settings
- Output enable/disable button for safety
- Compact and lightweight design
- Short-circuit alarm for equipment protection
Cons
- No Type-C charging port
- USB charging power limited to 18W
4. NICE-POWER DC Power Supply Variable 30V 10A
- Brand: NICE-POWER
- Manufacturer: NICE-POWER
The NICE-POWER model is the budget-friendly option, offering a 4-digit LED display with auto power calculation and a 5V/2A USB port for charging. Its compact design and rubber feet provide stability during operation, while multiple safety features ensure reliable performance for beginners and professionals alike.
Despite its low price, the NICE-POWER power supply delivers consistent performance for basic applications like battery charging and electronics repair. However, its lack of advanced features like encoder knobs or high-power USB ports limits its appeal for more demanding projects. The fan noise can be noticeable during extended use, which may be a concern for some users.
Pros
- Affordable price point
- Reliable safety features (over-voltage, short-circuit protection)
- Compact design with stable rubber feet
- Bright 4-digit LED display
Cons
- No encoder knobs for precise adjustments
- Fan noise during prolonged use
5. DC Power Supply Variable 0-30V 0-10A
- Brand: WANPTEK POWER
- Manufacturer: WANPTEK POWER
The WANPTEK POWER DPS3010U stands out for its inclusion of both USB and Type-C fast-charging ports, offering 3.6A output for quick device charging. Its coarse and fine tuning knobs allow for precise voltage and current adjustments, while its short-circuit alarm adds a layer of safety during operation.
This model is particularly well-suited for laboratory and educational use, thanks to its advanced safety features and versatile charging options. However, its slightly larger size compared to other models may make it less portable. The buzzer for short-circuit alerts can be disruptive in quieter environments, but it serves as a critical safety feature.
Pros
- USB and Type-C fast-charging ports
- Coarse and fine tuning knobs for precise control
- Short-circuit alarm for added safety
- Suitable for laboratory and educational use
Cons
- Slightly larger size reduces portability
- Buzzer alerts can be disruptive
