Product Description

Features:


Adjustable 15 Kind Current USB Load Resistor Electronic Discharge Resistance Capacity Tester DC Voltmeter Energy Voltage Ammeter
Important Tips:
The actual current size, please according to ohm's law: I = U/R + Fan Current & I = U/R (Fan closed state,Fan=200mA)
Voltage range:
Support QC2.0(5V/9V/12V/20V), Compatible QC3.0(3.8~12V,+/-2 Step), Android BC1.2(5V), Apple 5V/2.4A Lightning Voltage range and MTK-PE 5V/7V/9V/12V, etc.Fast charging pressure range
K1=20 Ohm/10W K2=10 Ohm/10W K3=4.7 Ohm/10W K4=2.2 Ohm/10W (+/-5%)

Support QC2.0(5V/9V/12V/20V), Compatible QC3.0(3.8~12V,+/-0.2 Step), BC1.2(5V), Apple 5V/2.4A Lightning Voltage range and MTK-PE 5V/7V/9V/12V, etc. Fast charging pressure range.
A designed according to the principle of ohm's law and through the resistor in parallel through a different switch, can produce 15 kinds of resistance of a new USB electronic load resistance discharge, when all the switch opens, is 2.2 ohm/10W, 4.7 ohm/10W, 10 ohm/10W, 20 ohm/10W 4 kinds of resistance in parallel at the same time, in 5V voltage almost can produce 4A discharge current.
The actual current size, please according to ohm's law: I = U/R + Fan Current & I = U/R (Fan closed state,Fan=200mA)
Resistor in parallel calculation formula: R=1/(1/R1+1/R2+...+1/Rn)
K1= 20 Ohm/10W K2= 10 Ohm/10W K3 =4.7 Ohm/10W K4 =2.2 Ohm/10W (+/-5%)
K5= Cooling fan wind strength Select or High voltage fan switch

Note:
1. the load device is working, winding resistance caused by large current, will produce very, very high temperature, therefore in the process of use, and just use the finished in a short period of time, absolutely can't human exposure golden metal radiator parts, to avoid the scald!Nor to flammable items contact tester, in order to avoid the fire!In use process must be highly vigilant!
2. considering the particularity of heat resistance, the initial use of electricity after a period of time will appear a few white smoke and smell, because outside the paint contains very little moisture, high temperature electric heating, moisture evaporates form the phenomenon of white smoke, produce peculiar smell by high temperature baking paint outside phenomenon, completely disappear after using for a period of time.This phenomenon is inevitable, belongs to the normal situation, do not have to worry about load tester can damage, please be assured that use.
The load application:
Can be convenient to test mobile power charging treasure, mobile phone charger, USB power output current is such as to amount to mark, so long as connect USB above.And can do it for mobile power supply and USB power adapter aging test, aging test discharge resistance will be hot, temperature is controlled in 80 ~ 85, please pay attention to prevent hot.
