New style USB intelligent electronic load, intelligent temperature control fan, precision adjustable potentiometer, load open indicator, plug and play.No components on the back to increase reliability and reduce quality control pointsNote: Some banks or chargers have a low-current automatic shutdown function.If the EL35 type load is inserted and does not start, due to the very small current consumption, such banks or chargers will automatically shut down.In this case, it is recommended to choose to turn on the load by default.The output current capacity of ordinary chargers or banks is only 1-2A, pay attention to the load should be reduced, otherwise the voltage will be pulled down or even off.The capacity statistics will only be stored once when the load is turned off or OPP OTP occurs to that the data will not be lost when the is turned on again.SMALL AND PORTABLE: This product is small and light, does not take up space, and can be easily taken .Product parametersInput voltage: DC3.5-28VMaximum discharge : 35WAdjustable load current: 0-5A current accuracy: +(1%+3 words)Operating temperature: -10C~40CDisplay type: 4-digit LED digital tubeCapacity statistics range: 0.001AH-9999AHOTP temperature: Greater than 70CFan speed: size intelligent temperature control fan (speed 8000+10%RPM) Cooling : intelligent temperature control fan + all-aluminum heat sinkAdjustment potentiometer: precision adjustable potentiometerProduct interface: USB-A interface, padFan start conditions: temperature 50 or Greater than 7WOPP : Greater than 36WProduct size: 81 x 40 x 41 mmProduct weight: 50gNote: The storage capacity is only once when the ON button turns off the load.Material: PCB colour: blackPackage Contents:1 x USB Tester Electronic LoadOnly the above package content, other products are not included.Note:Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.The measurement allowed error is +/- 1-3cm.
