1 / 7RUZIZAO 30V 10A Bench DC Power Supply
RUZIZAO’s 30V 10A bench DC power supply is listed with a five-digit TFT display, output curves and four storable settings. Its claimed OCP and OVP cut-off functions may suit electronics work where adjustable output limits and repeatable setups are useful.
At a glance
- Five-digit TFT display claims current and voltage readout to the milliamp level.
- The listing describes current and voltage output curves on screen.
- Four memory groups store current and voltage settings for recall.
- OCP and OVP thresholds are configurable. The listing says output cuts off if a threshold is exceeded.
- A lock button and switchable buzzer are described.
Pros and cons
Pros
- Four saved output presets can reduce repeated manual setup for common bench tasks.
- The claimed OCP and OVP cut-off thresholds offer adjustable output limits for connected loads.
- Banana plug and alligator clip output leads are listed, with compatible devices including computers, cameras, printers and Raspberry Pi 4.

What to know before buying
Listing details to confirm
Listing details are inconsistent about dimensions and weight: one field gives 13 x 21 x 23 centimetres, while the feature text gives 12*8*5 inchs and 3.3 lb. The title and details indicate 30V and 10A, but the stated 300 watts is not reconciled with that output combination. The listing also describes an Australian-specific power cord as available and says the package includes an input cord, without confirming that the included cord is the Australian version. Confirm the selected listing and output limits before purchase.
Who is it for?
A good fit for
- Bench electronics work where adjustable DC output and recallable settings are useful.
- Users who want a displayed output curve and configurable over-current or over-voltage cut-off claims.
Less suited to
- Buyers needing confirmed output capability at every voltage-current combination, since the listed 300-watt figure is not reconciled with the stated 30V and 10A.

The supplied evidence contains only a small aggregate rating sample, with all recorded ratings in the five-star category. This is too little to establish broader customer consensus, and no written feedback is available to identify specific strengths or concerns. Buyers should assess the listed display, controls and output claims against their needs rather than treating the ratings as proof of performance.
Frequently asked questions
What output rating does the listing give?
The title specifies 30V and 10A, while the details list 300 watts. The listing does not explain how the wattage relates to the voltage and current limits, so confirm the required operating range before buying.
Can it store output settings?
The listing describes four memory groups for saving and selecting current and voltage settings.
What protection features are described?
The listing claims adjustable over-current and over-voltage thresholds that cut off output when exceeded. This is a manufacturer claim, not an independently verified performance result.
Is an Australian power cord included?
The listing says an input power cord is included and separately says Australian specification cables are available exclusively for Australian users. It does not clearly confirm the included cord version, so check the selected listing.
