Hey OP- I know you said some Power Banks are overkill, but not knowing your usage on the Slate 7-it’s hard to say how small you want or big you want to avoid. In any event, I run two Slate 7’s in my Travel Sports Wifi Network and Streaming setup. For away games I don’t bring out the HUGE POWET STATIONS, bc I don’t have the same access I do at our home fields. That stated though, I run both the Slate 7’s with the following for my away/smaller setups: Anker Prime Power Bank, 26,250mAh... https://www.amazon.com/dp/B0F66LNB8D?ref=ppx_pop_mob_ap_share It’s the Anker 26k mAh laptop/tablet power bank. About 6 inches tall and as thick as 2 iPhones. Has two (2) USB-C 140Watt ports and a USB-A port. I typically power the Slate’s with the (PD) port on Top. Def still allows for tethering. Hope that helps.
How hard did you look? I needed one recently and spent 60 seconds on Google identifying a few candidates based on vendor, then spent another 10 minutes reading reviews. None of the information was remotely difficult to find. Also, Anker makes great ones: https://a.co/d/09Xvx5WD
This is what I do, I have 5 batteries and and a Anker Prime battery pack that I charge with while using the drone. Works very well for me, I also have a extended life battery but with the 5 battery setup I rarely use it. This is the battery pack I use https://www.amazon.com/dp/B0F66LNB8D
