I just bought a GoPiGo 3 starter package (great thing, I love it!). I live in Europe and cannot use the standard power charger that comes with it and I’m looking for an alternative to use.
In the technical specs it says that operating voltage of the GoPiGo 3 is 7-12V. I get 9V from my battery pack. However, I also want to use the power cable for programming. If I connect the USB charger directly to my Macbook, I get 6V. I also get 6V if I plug in the USB cable to my iPhone charger (it says output is 5V/1A on the charger). Another charger I tried gives me 19V! (output labelled as 5V/500mA on the charger).
What is your experience/recommendation? How high is the voltage if I would use the standard charger? Is it fine to just use my Macbook as a power source during programming?
