USB Charger Doctor Inline Voltage, Current & Capacity Meter Tester
This USB In-Line Voltage and Current Meter with LCD Display is a lot like the Charger Doctor we carry. Just like the charger doctor, you can use this meter to find out if your voltage is too low or your current draw is too high.
Use the USB In-Line Voltage and Current Meter to measure the working voltage and current output for any USB port and project. This blue plastic dongle plugs between a USB device and passes the data lines through. This voltage meter has an LCD display that shows off voltage, watts, amps, and mAH and instantly reads the numbers out for testing devices such as chargers, cables, and cell phones.
You can use this device from 4-20VDC input voltage (although most USB devices tend to hover around 4.75 to 5.25) and up to 3A of current. It's a very handy tool for testing USB devices above 7VDC, checking load levels and debugging battery chargers and boost converters.
Features :
- Compact and easy to carry, no additional power supply, plug, and play
