How does the automatic stop work?

You press the one-touch button and the pump runs until it reaches its target vacuum, then shuts off on its own. That removes the guesswork of holding a manual pump.

Can it seal jars or containers?

No. It is built for reusable vacuum-sealed bags only, so mason jars and rigid containers need a different sealer.

How long does the battery last?

It runs on a 3.7V rechargeable battery at 110 W. Expect several bags per charge, with fewer as the battery ages; recharge before a long sealing session.

What comes in the box?

The vacuum pump and 10 reusable vacuum bags. Extra bags are the only accessory it takes.

Is it good for sous vide?

Yes, that is its main use: seal seasoned food in a bag before the water bath. Pat wet foods dry first so the seal holds.

How does it compare with a countertop vacuum sealer?

It is smaller, cordless and cheaper to run on reusable bags, but countertop sealers handle wet foods and containers and usually pull a stronger vacuum.
