Simple little diagnostic tool. Functions well to monitor battery charging status. Shows volts supplied and amps drawn. Widely applied to test 3C products.
Testing voltage/amps output and power draw for USB-driven devices. Easy to read, helps identify which chargers put out the most charging current.
This USB meter has been a real benefit in sorting iPad, iPod, iPhone, cables and wall warts adapters into how well they are working for each of these devices.
A very handy USB power monitor to have around for checking both VDC and the current a USB device would draw with re-charging and go to zero when fully charged.
Unlike other USB multimeter, which displays voltage and current in alternate mode and you have to wait for the other mode. This device displays both voltage and current simultaneously!
Please allow slight measurement deviations due to manual measurement.
