Mini USB load tester, external battery discharge resistance with 1A 2A 5VDC current button

Features:

1. Current test: As long as the USB is connected, the test instrument can test whether the output current of mobile power bank, mobile phone charger, USB power supply, etc. is current. conforms to the standard and can perform aging tests on mobile power. 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 5V 2.1A.
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 and high compatibility, and can be used in more fields.
5. Easy Installation: Simply insert the test instrument into the power bank, charger, or any other device that needs to be discharged. No other tools are required, and installation is super simple.
Specifications:Item Type: Mini USB Load Tester
Material: Printed Circuit Board
Power: 5W-10W
Type: Fixed Resistor.
Operating Voltage: 5VDC

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 = 2.2 Ohm/10W
Description: The USB load resistor is mainly used for discharge tests.If the output current of the charger or power bank is 2 A, the power output of the load meter is 5 V x 2 A = 10 W; if the output current is 1 A, the power output is 5 V x 1 A = 5 W.

Package List:1 x Test Equipment
Note:When charging, the winding resistance inevitably generates a very high temperature due to the high current.Therefore, during use and for a short time after use, the human body should not touch the gold-plated metal heat dissipation part to avoid burns!Do not allow flammable objects to come into contact with the tester to prevent fire!In short, extreme caution is advised during use!
