Multifunctional USB Tester with Auto Shut-Off, Digital LCD Display for Voltage, Current and Safety Measurement

Discover our USB tester, an essential tool for monitoring and analyzing your charging sessions with precision and ease. Thanks to its unique LCD screen, you can view voltage, current, and capacity in real time without any tedious operations. Simply connect it via the USB interface to begin monitoring. This tester supports the fast QC2.0 and QC3.0 protocols and features a screen rotation function for comfortable reading from any angle. It also has a power-off backup function with 9 memory groups, allowing you to temporarily retain the current capacity and energy during a power outage. Upon power restoration, accumulation resumes automatically, but you can also choose to manually reset the data if necessary. Its intelligence extends to memorizing charging capacity: it can save the mAh data of up to 9 different devices after a power outage, making it easy to verify the actual capacity of your chargers and batteries. Made of robust ABS, this KWS MX18 model offers accurate measurements within the following ranges: current from 0 to 5.1A, voltage from 4 to 30V, capacity from 0 to 999999 mAh, energy from 0 to 999999 mWh, timing up to 99 hours, power up to 150W, and load resistance from 0 to 999.9 Ω. It also monitors the internal temperature (0 to 80°C) and positive/negative voltages (0 to 10V). Your order includes: 1 USB tester and 1 user manual.
