I wish me a budget 10000 mAh size "phone slab format/shape" power bank with like 18W output at 9~12V kind of "fast charge" style, and a built in Google air tag. They already have a button and a battery and a case; only need to add the BLE and the Google-mandated buzzer. I'd pay 5 bucks more than for the competition without the integrated tracker. That should easily cover the cost, right?

A Kindle or cover with Find My support would make my wife overflow with happiness.

Take a cover, place inside a credit-card sized airtag
