I like this idea from a practical getting into shape prospect. I got an under desk elliptical but I really wish it was setup to charge a phone or battery- then I’d really feel like I was getting something tangible out of the work put in.

Neat! Thanks!
Yeah I feel like it could be a nice motivator. Like can I do it enough to be the sole source of my phones charge.
Maybe to power one of those dancing flowers, instead of solar use muscle!
The process of filling the empty tanks to 100 psi takes 5-10 pedaling sessions per day for roughly a week.
Eeesh.
Compared to 5 minutes when using electricity, it really puts things into perspective.
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.
I wonder what the round up efficiency is like.
