DROK® Pocket Digital Multimeter USB 3.0 Hub, OLED Display DC

DROK® Pocket Digital Multimeter USB 3.0 Hub, OLED Display DC 13V Voltage Ampere Power Capacity 4in1 Multi Tester, Voltmeter Ammeter Power Capacitance Meter, Support QC 2.0 Fast USB Charging
- 3 MODE USB MONITOR: Our sophisticated versatile USB digital multimeter kit is a utility tool for measuring voltage, current, capacity and power via your phone/battery. 1 button achieve the switching of 3 different modes (direct mode, quick charging mode and disconnected mode), super simple to evaluate whether the USB charger are outputting acceptable voltage/current to your device.
- HIGH QUALITY OLED DISPLAY: 0.91″ OLED screen has the advantages of high brightness, high resolution, stable and clear digital display, low power consumption. The USB meter has large screen for four values displaying simultaneous; black background and bright white font, clear and easy to read.
- MULTIFUNCTION: The feature-rich multiple USB detector has 7 different functions (screen rotation, screen closing, capacitance unite switch, capacitance storage, current zero calibration, over- and under-voltage alarm, operating mode selection). The multimeter not only can detect the power/quality of the chargers and USB cables but also support QC 2.0 fast charging.
- WIDE APPLICATION: The handy USB tester can be applied to many electric devices, such as mobile phone, portable power bank, tablets, pad, camera. However, please NOTE that this tester cannot be used for inductive load, like the load with motor and fan, relay.
- ORDER NOW: Are you still worry about the quality of your charger cable? Do you know the power use of raspberry pi or Arduino board or the performance of your solar charger in different conditions? The USB digital multimeter with 7 different functions can help you. So don't hestitate to click "Add to Cart".
Unacceptable voltage and current output from the computer, USB wall/car charge will do great damage to your mobile device. Now here is DROK OLED Digital multimeter to help you have a better understanding of your power source, USB charger cable. PARAMETERS: Voltage range: DC3. 7-13V Voltage accuracy: (0. 2%+1 words) Current range: DC0-3A Current accuracy: (0. 8%+3 words) Capacitance range: 0-99999mAh Power range: 0-39W Energy range: 0-999Wh Capacitance resolution: 1mAh Energy resolution: 1mWh Static consumption: about 10mA Display screen: 0. 91" OLED screen OUTSTANDING FUNCTIONS: 1. Mode selection: Press the key to choose among direct mode, quick charge mode and disconnected mode. 2. Over-voltage & under-voltage alarm: When voltage is higher than 5. 3V or less than 4. 7V, it shows an arrow to inform you of over-voltage/too-low voltage. And the arrow will not stop flashing until voltage is within normal range. 3. Current zero calibration: The USB meter might have larger testing error in terms of small current due to aging components and changing environment. To deal with such case, you need to have this meter done the current zero calibration. 4. Screen rotation: Long press the KEY for about 4sec and LED will light on, then release it when LED light off, in this way, its display screen will rotate. 5. Screen closing: Long press the KEY for about 6sec and release it later to close the display. 6. Capacity unit switch: Press the KEY for about 4sec and release it when LED light on and later light off, then you can choose to display capacitance in mAh or mWh. ORDER NOW! Hurry to adding it to your cart.
