It is compatible with any USB charging port, including portable solar panels, the PowerPot, your home PC or laptop and any charging accessory you have. Plug it in between your charger and your USB device (smartphone, mp3 player) and watch as it provides real-time feedback!

Having the Practical Meter will help you know your power. You will know if your laptop is charging your iPhone at full speed or a mere 50%. You will be surprised to discover the differences in charge rates that occur when charging with different brands.
