The “GettaGrip Musclephone” is still going through the patent certification but according to a feature in the December. 12th Financial Times:
“Forty seconds’ vigorous squeezing of the GettaGrip Musclephone gives a full recharge of the lithium-ion battery. That’s 20 seconds per hand. No more scrabbling around for a recharger. No more rationing calls because the battery is getting low. And all the while developing a grip like a gorilla.”
No word on actually how much the grip weighs but image if you could charge your phone like this… and develop a grip like a gorilla… the possibilities are endless!
