I have. I would probably use my last phone for at least another year if it didn’t loose system updates. There’s too much important personal data (bank, photos, messages including medical info…) on the phone to risk using it unsupported. At least to me it is not worth it so I try to buy a phone with reasonably long support and buy a new one soon after the old one looses support.

Generally for extended periods you would pedal with something like 100 - 200 W while small electric compressors seem to be in > 1 kW region (and don’t get tired as quickly :D).

So basically with pedal power you could feasibly run some led lights and portable electronics but anything beyond this is not practical.
