What to know before buying

Listing details to confirm

Listing details are inconsistent or unconfirmed: the details table gives input as 115 Volts, while the product description states AC 230V/115V±10%; 50Hz/60Hz. The title says 4-LED display, while feature text calls it a four-digit display, and the description says four rotary encoders whereas another feature refers to an encoder knob. Check the selected unit's input compatibility and control/display arrangement before buying. USB charging is stated as up to 18W and may fall to standard 5V1A when the device or cable does not support fast charging. OCP interruption and alarm are described as conditional on enabling OCP.

Aggregate ratings lean positive overall, with most ratings in the four- and five-star categories, but a smaller one-star share indicates that experiences are not uniformly favourable. Without written feedback, the ratings do not identify particular strengths or concerns. They offer limited guidance for a bench supply whose input specification and display/control descriptions should be checked against the buyer's needs.
