Feature: 1. COMPREHENSIVE DETECTION: UD24 color display large screen, multi purpose, diverse gameplay, detection of various USB and Type C interface devices, as well as various DC power supplies and equipment 2. OBSERVE AND RECORD YOUR DEVICE: After fully charged, the charging power value, and then add 1‑3W on this basis, which is the continuous value of how many watts your full power off setting is less than, so that the system detects less than your device is fully charged. After the power is cut off and continues for the virtual charging time you set, the system will display a power off icon and cut off the power output to protect your equipment 3. SUPPORT USER SETTINGS: Users can set the full power off switch, full power off parameter conditions, timing charging time, and overcurrent, overvoltage, low voltage and other parameters according to their actual needs, so that the equipment can be fully automatic and unattended. The parameters you set automatically run, real time monitoring and automatic power off according to the corresponding settings to protect your charging equipment in an all round way, and your charging becomes more secure, interesting and playable 4. POWERFUL AND EASY TO OPERATE: Support QC2.0 3.0 fast charge trigger, can induce a variety of fast charge high voltage, realize the power supply of fast charge high voltage equipment, a variety of fast charge detection, identify the true and false equipment. Press and hold two buttons at the same time switch to the automatic face of the fast charging protocol, press and hold a single button to enter the protocol detection, and click and short press again to realize the automatic detection of the fast charging protocol. The operation is simple and convenient, and the function is powerful 5. FLEXIBLE AND CONVENIENT: UD24 adopt a special metering chip, and both positive and negative currents can be sampled and measured, and the output can be used as input. The C port can be used on the charger or on the mobile phone. The current value is the self consumption current of the machine, which is a normal situation Specification: Item Type: Digital Voltmeter USB Tester Model: UD24 Material: ABS Product Voltage: 5V-32V Voltage Measurement Range: 5.000-32.00V Current Measurement Range: 0.000-5.100A Capacity Accumulation Range: 0-99999mAh Power Accumulation: 0-999.99Wh Power Metering Range: 000.00-163.00W Temperature Measurement Range: 0-80℃ Timing Maximum Time: 999 Hours 59 minutes 59 seconds Display: 2.4in TFT high definition display Function: USB and DC current, voltage, capacity, power supply and other testers Support Protocol: PD2.0, 3.0, 4.0, QC2.0, QC3.0, BC1.2.
