Description of πŸ”Œ DROK 180043 USB Multimeter with OLED Display, DC 13V Voltage Ampere Power Capacity, 4-in-1 Multi Tester including USB 3.0 Hub

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. One 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. 91β€²β€² 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 worried 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 hesitate to click "Add to Cart".

It would be nice if it came with a cable.

Complete loading information. It would be nice if it came with a cable instead of a direct USB connection if the charger isn't in an accessible location. I've tested a few USB 3 extension cables but they don't seem to be passing any intelligent charging information and will cause the charger's output current to drop to 1A. Also the display font is really really small to show all the information on the display though and bright enough and yet legible.

Pros
  • Stable test results
Cons
  • Updates available

Works well has good performance and accuracy

Works great. I tested the voltage accuracy with my desktop multimeter and it was good to measure both low and high current devices (iPad or Raspberry Pi). I have only tested USB 5V power supplies, not higher voltage power supplies, and I have not tested the accuracy of the current/power measurement. I'm always concerned that devices like this won't give accurate results and since I bought this as a quick test for other USB powered devices I wanted to make sure the DROK was accurate. I'm glad it

Pros
  • Price
Cons
  • Unbelievable price

My favorite USB charging diagnostic device!

The OLED display is very bright and clear as advertised! I like having 3 different connection modes, although it's a little awkward to hold down the button while plugging into a USB port. Sequences for EVERYTHING. The behavior of the unit is logical and predictable. The thing just works! Economical yet high quality design. The instruction manuals (in English) are obviously written by a non-native speaker but manage to convey the necessary information.

Pros
  • Very good value for money
Cons
  • Old model

USB-A Large Pocket Multimeter

I've always wondered what voltage and current my USB devices need at a certain charge level and what my various USB power adapters can do. Now there is nothing to guess! The OLED display is high-contrast, making text easy to read (if you can read small text), while providing voltage, current, and power readings. In addition, this USB-A multimeter shows the total mAh consumption per session, with up to 10 different sessions to choose from. Rotating the display 180 degrees is also useful for…

Pros
  • Pleasant
Cons
  • old
