The reality of battery power required, storage and recharging comparing a phone, computer or car is not even in the same world in comparison to a 121 jet.
A Tesla battery will take a 3,000 pound car a couple hundred miles or so. To take a hundred thousand pound aircraft to 30,000 feet and a few hours of flight or more requires a huge (heavy) amount of battery power/weight.
Also the ability to recharge or relace the cells for a rather quick turnaround is required. The fact that fuel burn and weight loss makes an aircraft more economic over time is lost on battery powered aircraft as well.
