Adafruit Universal USB / DC / Solar LiPo Charger and The Micro:Bit

Hi,

I have just spotted the subject product on the PiMoroni Web Site and had a question.
This Solar Charger
Could I use this the power out socket to power a Kitronic MicroBit Motor Driver Board?

Every year at school I get the Year 6 children to work towards a STEM Robotics competition, building a wooden chassis for a MicroBit powered buggy to enter in a couple of challenges. One is along the lines of PiWars PiNoon (burst your opponents balloon). At school, we have just embarked on a sustainability venture, so I would like to add an element of renewable energy in this project, so using solar power either for powering the buggies, or at least charging thier rechargeable batteries (I normally use 4 x AA Alkaline Batteries).

Thanks
