_______________Product Information______________




Feature:
1. Current Test: As long as the USB is connected, the test instrument can test whether the output current of the mobile power bank, mobile phone charger, USB power supply, etc. meets the standard, and can perform aging tests on the mobile power supply and USB power adapter.
2. Performance
Specifications:
The second gear of the test charger is 2.2Ω, and the charger maintains a voltage of 5V and the current can be stabilized at 2A, which proves that the charger supports 5V2.1A.
3. Current Button: The test instrument has a 1A 2A current button that can switch 1A or 2A current discharge, which can be switched freely through the switch, which is very convenient and easy to use.
4. High Compatibility: This is a test charger with a very stable current with high compatibility and can be used in more fields.
5. Easy Installation: You only need to insert the test instrument into the mobile power supply, charger or other equipment that needs to be discharged, no other tools are needed, and the installation is super simple.

Specification:
Item Type: Mini USB Load Tester
Material: Circuit Board
Power: 5W-10W
Type: Fixed Resistance.
Working Voltage: 5VDC
Working Current: 1A 2A
Actual Current Size, Please Follow Ohm's Law: I = U/R
Parallel Resistance Calculation Formula: R=1/(1/R1+1/R2+...+1/Rn)
K1=4.7Ohm/10W, K2=2.2Ohm/10W
Description: USB load resistance is mainly used for discharge test. If the output current of the charger or mobile power supply is 2A, the load meter power is 5Vx2A=10W, if the output current is 1A, the load power is 5Vx1A=5W.

Package List:
1 x Test Equipment 

Note:
When the load is working, the winding resistance will inevitably generate a very high temperature due to the high current. Therefore, during use and within a short period of time after use, the human body must not touch the gold metal heat dissipation part to avoid got burned! Do not allow flammable objects to touch the tester to avoid fire! In short, you must be highly vigilant during use!
