Not just a load, but a multimeter: The load tester can continuously discharge for long periods at 35W. It's also a USB multimeter that can be used to monitor the voltage, current, capacitance, electrical energy, power, temperature, conduction time, discharge, and aging of smartphones, power banks, USB chargers, and USB wall chargers in real time.
Dual-Adjustment Design: The battery monitor withstands the widest voltage range (DC3-21V) and current range (0-3A). Our USB detector features a dual-adjustment design (current coarse adjustment 0.1A and current trimming 0.01A) and intelligent temperature control for more accurate test results.
Intelligent Temperature Control: Our resistor set features a large fan and a high-quality aluminum radiator for powerful heat dissipation. Additionally, the load resistor features intelligent temperature control, effectively preventing module damage.
Multiple USB Ports: This feature-rich battery tester offers a variety of USB ports, including a mini USB data cable port, a USB Type-C for reverse USB connection, an Android data cable port, and a single-wire terminal or aluminum battery power test port. Suitable for detecting the quality of various USB chargers. Note: Not suitable for Apple iPhone data cable ports.
Easy operation and installation: One button clears or resets data. Simply connect the electronic load to a power bank, smartphone, charger, or other device that needs to be discharged (not suitable for iPhones and their charging cables). Installation is simple and easy, with no wiring, screws, or tools required.
