M3P battery to power bank adapter?

[GroovyGeek]

My Air2s came with a useful battery to USBA power bank adapter. It came in very handy during backpacking trips to use the remainder of the drone batteries to recharge the phone. Does such a widget exist for the M3P? This perhaps

This one works, if you can find one.

I have one very similar to that one and it works great. Perfect when you charge a battery but don’t get a chance to use it. Just discharge it to 60%.

I ordered one from AliExpress, it is just a cradle for $15, no electronics. It is a bit on the bulky side for trekking, the Air 2S one was very diminutive. I will keep looking.
