What to know before buying

Listing details to confirm

Listing details are contradictory or inconsistent: it describes a 3-digit display in the title and product details but a 4-digit screen in a feature, and gives weights of 1.5 Kilograms, approx. 2.75lbs and about 2.95 lb. Input details also differ between 220V and AC 230V ±10%, 50Hz, so confirm the display, weight and input requirements for the selected listing.

Who is it for?

A good fit for

Electronics hobbyists or repair benches needing adjustable DC output for component and circuit testing.
Teaching or workshop settings where a bench-top supply with stated CV/CC operation is useful.
Buyers who want the advertised alligator leads and AU power cord in the claimed kit.

Less suited to

Buyers who require a confirmed display specification or settled input-voltage details without checking the listing first.
Projects needing output above the listed 30V, 10A or 300 Watts.
