Best Overall
Humutan One-Touch Battery Electric Jar Opener
Our verdict: A true one-button, hands-free opener with a high torque motor and adjustable jaws.
The Humutan is a battery-powered electric jar opener with a one-touch, hands-free design, a high torque motor and adjustable jaws. The listing says it fits most standard jars, and it costs under $25.
It wins because it asks the least of your hands. You set it on the lid, press one button, and it grips and turns without you holding on. For someone with arthritis or a weak wrist, that is the difference between a gadget that helps and one that needs its own technique. The adjustable jaws handle different jar sizes without a manual twist. It ranks above the INSTACAN because the hands-free design needs no supporting hand on the jar for it to work.
Buy it if you want the simplest operation available and will open jars every day. Keep spare batteries around, because a stubborn lid pulls the motor hard.
