I've handled with two instruments and a measuring adapter, whenever I wanted to know something about the power consumption / charging current a USB device - a rather complex structure, which can not be "times" is doing. The POWER-POND simply plug in between and you have an overview of voltage and current - very well done, I find the also implemented mAh counter which thus provides a data drawn by the device amount of energy the battery capacity and data for up can store about ten units. A great value for money !!
