AUKEY 20,000mAh Portable Charger with Lightning and Micro-USB Input -> Amazon link https://www.amazon.com/AUKEY-20000mAh-Portable-Lightning-Micro-USB/dp/B0176HQ1O8/
Can be yours for $30 with prime one day, you could (in theory) pick it up at a nearby Amazon locker.
Amazon Aukey its a bit heavy so not sure if it'll end up squishing anything if I put that in the pocket. but maybe I can even fit it between where the xbox controller and Go wand since there seems to be a space there.
Just recently got the Go and see how some people just attach a smaller battery to the headset to keep it charged for an extra hr or two. Also I think I saw the Go doesn't have bluetooth for wireless headphones, so I'd need an adapter for that, which I'll either get, or just plug in a wired headphones. So just making sure it can fit all those things. And seems like it can.
What other accessories have you all included in the case to use with your Go?
Seems like the case would be perfect if it was made of hard-shell.
Thanks for the Amazon link too.
