The charger doctor is a useful tool for monitoring the voltage and current consumption of any item you are using via a USB port.
Monitor the charging state of you USB lipo charger or the current of you smartphone. Check the voltage output of the USB port under load. Determine if a port is rated at just 100mA or full 500mA USB spec.
The Charger Doctor can monitor up to a 3 Amp load so also suitable for use with higher power USB charge adapters. The data lines are passed staight though the device so won't effect any data communication with the device on test.
The unit will operate from a 3.5-7VDC input voltage (although most USB devices tend to be around 4.75 to 5.25) and up to 3A of output current. It alternatly flips between voltage and current displays every 3 seconds or so. It's a very handy tool for testing all types of USB devices, checking load levels and fault finding battery chargers and any USB project you are working on.
