Why to buy this comprehensive package included both USB load resistance and onec USB C Power Meter?
USB load resistance, is mainly to do discharge test, including the mobile power supply and USB power adapter aging test.
With one USB load resistance and one USB C Power Meter Tester, you can test mobile power charging, mobile phone chargers, USB power supply output current standards, and test the real capacity of your power bank at any time.
Product Features Of Eversame USB Load Resistance
Voltage Range: 3-21V DC
Constant Discharge Current: 0.1-4.5A adjustable(coarse adjustment knob for 0-3A, fine adjustment knob for +/-0.2A)
Current Error: Less than 2%+3mA
Constant Rated Discharge Rate: 35W(When the voltage is 21V, the current of the constant discharge should adjustable to be less than 1.6A)
2 in 1 Type C USB Tester
Featured with over-voltage protection, over-current protection, under-voltage protection, low energy protection and alarm system. This upgraded USB Type C tester can detect safety and maximally protect the appliances from damaging.
Allow you to detect the charging status and process of your USB-enabled and type c-enabled devices at the same time.
Intelligent Temperature Control
The intelligent cooling fan will automatically kick on when temperature is higher than 55°C, to help to prevent an overheating situation.
2 Adjustment Knobs
There are two adjustable controls, one is for coarse-current (0-3A) and another is for fine-current (+/-0.2A) adjustable trimming, enable you to precisely set the load you want.
COMPREHENSIVE PACK: Come with one USB constant-current electronic load and one 2 in 1 Type C USB Tester, making it more conveniently to test mobile power charging, USB power supply output current standards, and test the real capacity of your power bank.
