1、4 Working Modes: CC constant current operation, CV constant pressure operation, CW constant power operation and CR constant resistance operation. There are three intelligent safety protections in the discharge detection process, which can monitor the state of the discharge tube in real time, safe and reliable. External wired NTC thermometer can realize internal and external dual temperature measurement. 2、Digital Display: 2.4in high definition large color screen electronic tube digital load meter. Intelligent temperature controlled colorful fan, quick in heat dissipation. 150W high power, wide voltage, 20A high current, strong performance. 3、Extensive Using: Supports testing for Android, Type C cable, Mini and other wires, and displays various test data on one screen. Through inspection and testing various data cables, charger tests, discharge aging, DC power adapter current, voltage, power and other parameters, the operation is simple, convenient and fast. 4、A Useful Tester: 150W load discharge aging test adopts built in large discharge tube, and the temperature is maintained at about 50-80 ℃. Easily test the voltage, current, capacity and other data of various power supplies such as lithium battery and USB charger. 5、Easy to Install: Comes with a light weight and a compact size as well, the electronic load tester is very convenient to install within minutes. Item Type: Electronic Load Tester Material: ABS Working Current: 0.2-30A Constant Load Adjustment Rate: ± 3% + 3 bytes How to Use: 5. Capacity and Power Test of Mobile Power Supply: First, fully charge your charging bank, and then clear the load capacity and power to 0. Then start to connect to the load and set the discharge value to start discharging until the charging bank is discharged. Read the accumulated capacity and power value on the display screen, which is the approximate capacity and power value of this charging bank. Since this product has power failure memory function inside, the discharge process can be completed at one time or several times, and the capacity value can be checked after the power of the charging bank is exhausted. 1 x Electronic Load Tester 1 x Adapter 1 x Adapter 1 x Red Cable with Crocodile Clip 1 x Black Cable with Crocodile Clip 1 x Computer Online Cable 1 x Temp Sensor 1 x Accessory with 4 Interfaces 1 x User Manual
