The Keweisi USB Detector is ideal to find out how much power a solar panel generates. The detector in pocket size can be placed easily between the solar panel and the device to be charged, and thus measures the current and the voltage supplied by the solar panel. As a result, also the position in which a solar panel generates the most energy can be conveniently determined.
The USB Detector can be used not only in combination with a solar panel, the device is also ideal for the determination of the charging current and voltage which is supplied by, for example, a USB Power Bank.
When the USB Detector is in use, it shows the voltage (V) and the charge current (amps). In order to calculate the generated energy in watts, volts should be multiplied by amps. In this way it can be easily determined, how many watts a solar panel generates.
