Voltage: 3.7-30V; Current: 0-4A.Fast charge recognition, widely compatible. Supports QC2.0, QC3.0, 2.4A/2.1A/1A/0.5A, Andriod DCP,SAM-SUNG charge protocol identification, let you know the state of charge of the phone.5-bit resolution for more accurate measurements. The screen can be turned off with one on and has a fl screen function. function using high-precision thermistor r, celsius and fahrenheit free switching.AT35 has power-off storage function, which can store capacity and energy data when the mobile power is cut off, which is convenient for subsequent viewing and convenient for capacity energy measurement of mobile power.Note: Other USB s that do not have a power-down storage function cannot test capacity and energy.Measure the quality of the charger: connect the same load, compare the no-load and the load, the greater the voltage drop, the worse the charger capacity is, the worse the quality; the voltage drop is not obvious or the voltage rises, the load capacity of the charger and the quality be better.Capacity measurement range: 0-99999mAhEnergy measurement range: 0-99999mAh-999.99WhLoad impedance measurement range: 1 -9999.9 Temperature measurement range: 0℃-65℃/32℉-149℉Operating temperature range: 0℃-45℃/32℉-113℉Voltage measurement resolution: 0.01VCurrent measurement resolution: 0.001AVoltage measurement accuracy: +/- (0.1% + 2words)Current measurement accuracy: +/- (0.2% + 4 words)Power measurement range: 0-120WRefresh rate: 0.5Hzcolour: as shownMaterial: ABSSize: 64x22x12mmPackage Contents:1 x AT35 USB Only the above package content, other products are not included.Note: Light shooting and different displays may ca the color of the item in the picture a little different from the real thing.
