Before i break out the solder gun and make one myself, i wanted to ask. Is there a unit that uses magsafe magnets that does wireless charging pass through? The idea would be to have this device on the back of a phone and when a charge is applied while it’s on a phone it passes the charge through to the phone.
Maybe the Heltec MeshPocket?
I know it supports QI2 but I’m not sure if it can do pass-through or not.
I think you’re right, MeshPocket is the closest option. Its docs read like it should act like any other power bank. There’s no explicit warnings that it cannot charge a phone while receiving a charge.

Yeah, it says so in the FAQ
Does it support charging and discharging simultaneously?
Yes. You can charge the MeshPocket via the USB-C port while simultaneously using its wireless charging to charge your phone. (Current power allocation: Wired charging input 10W, wireless charging output 5W. Total output may be limited by input power capability.)
