I received a FreeLoader Pico the other day, and I put it to work charging my cellphone while on the go. It does a fantastic job of that, but I wondered what else I could use it for. Ah, a power source for my Arduino Microcontroller. It does a great job of that as well. No more looking for power connections, I just set the small solar panel with integrated Li-ION battery in the sun and charge. A bargain at $30.
