Ah, that's too bad. Given how little energy this keyboard consumes, I was hoping it could run on the solar charger indefinitely. Hell, maybe a supercapacitor could be enough, hm. EDIT: I think you've overestimated active power consumption, I don't know if you'd actively be holding down keys for 2.5 hours per day... Also you estimated using this for 11 hours a day straight, which seems like way too much.
