## Description

International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions.

Review: Works well but not many features - I am using this for a constant discarge of my power banks in combination with a professional USB power meter. The electronic load works well. The accuracy of the A display is a bit off (not much) but constant. The device itself is small with nice "feet" so the warm heatsink cannot contact anyting for safety. Also the ventilator switches on and off to keep the termperature constant. Because the imputs can be USB-A male, micro USB-B female and USB-C female you can connect every USB cable coming from a power supply / power bank. Works well.
Review: Funciona muy bien y es bastante preciso. Según las mediciones que he hecho, la corriente que se solicita sólo está desviada por 0.01A en mi unidad, lo cual es poco. Mi única observación es que el potenciometro esta un poco suelto, les faltó soldarlo completamente plano a la placa. Pero no tengo problemas, funciona excelente por el precio.

## Features

- What is it: it is a USB intelligent temperature control electronic load; with high power, high current, high voltage and intelligent control features.
- Protection Function: OVP overvoltage protection (25V-30V overvoltage protection, digital display OVP, permanent damage after more than 30V); OPP over-power protection (load temperature is greater than 80 °C, the device stops working, digital display OTP); OTP over-temperature protection (power greater than 25W, equipment stops working, digital display OPP).
- Application: can provide 4A, 25V, 25W (3 values can not used over range) constant current test discharge task. The friendly human-computer interface and excellent performance indicators can meet the diverse testing needs. It is suitable for measuring the output current capability of the charger, using the bulk aging test of the charger factory, and measuring the quality of the Micro USB charging cable and the Type-C charging cable.
- International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions.

*by M***K on 2 March 2023*

The device works well however we can only achieve 17W for some reason. We have had to use additional loads to boost the amount for our testing to 25W which wasn't ideal.
