I’m going on a trip to Canada soon and I wanted to be able to take my Analog 4 with me on the aircraft and play with it there. The problem is no power so I looked for a way to solve this. I managed to find a battery on Amazon.co.uk that supplied a 12v DC output that the Analog 4 needs to run. I bought it and it arrived today and sure enough it works great - powers the Analog 4 completely. I’ve not tested how long this battery will last but I would hope for more than an hour.
I made a video of it in action if you want to see: https://www.youtube.com/watch?v=JAlGxWWYhlE
The battery, if you want to get one yourself is a Poweradd Pilot Pro2 23000mAh Multi-Voltage (9V 12V 16V 19V 20V) Portable Charger External Battery
I can’t wait for the strange looks I’ll get on the aircraft as I start playing around with the Analog 4, thankfully the battery is rated as 85Wh which is less than the 100Wh limit that can be taken on board aircraft.
Enjoy!
