We are updating our Pi Jam equipment and have decided to get 10 x Pi 4s. Along with these we are getting a couple of CamJam Robotics kits, however I need some advice on what power packs to buy to enable the Pi and the Robotics kit to be mobile.
I have used the CamJam kits before with a Pi 3 and used a these 5000mAh USB packs

But I have heard the Pi 4 is more power hungry so hence the advice request.
The robots will only be used for the duration of the Pi Jam (1 hour or so) so don't need to last too long before needing a re-charge?
