D: Allow APP stay after screen locked, not be cleaned. E: Type-c is just to measure, not support all Type-c quick charge, not trigger.
- LD25 4-bit led digital display tester have some Advantage: 1. Display upgrade; 2. Protection upgrade; 3. Interface upgrade; 4. Cooling upgrade; 5. Precision multi-turn potentiometer; 6. Intelligent temperature control fan. 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.
- UM34C Android Phone APP Control. No need professional wiring, simply the operation, only need to download APP. Real detect charging status of USB power supply, voltage, current, capacity ,temperature and etc. other multi-function multi-data measurement display, high precision comparable professional equipment. At a glance, more convenient.
- Note: LD25 USB Electronic Load Tester is not reverse polarity protection, the input polarity can not be reversed, otherwise the product is permanently damaged and cannot be repaired!
