How does RoboSeal work?
Place RoboSeal on the lid and press once. One-touch operation draws the air out and stops automatically when the jar is sealed — no hand-pumping, no guesswork, no over-sealing.
How do I charge RoboSeal and how do I know when the battery is low?
RoboSeal is rechargeable via the included USB-C cable. The built-in digital battery indicator shows exactly how much charge remains so you're never caught mid-seal without power.
What lids are included, and are they reusable?
The kit includes 50 reusable BPA-free lids — 25 regular mouth and 25 wide mouth — plus a USB-C charging cable and a jar-opener/seal-release tool. Mason jars are sold separately.
Can I use RoboSeal away from the kitchen counter?
Yes. RoboSeal is cordless and portable, so it runs anywhere — kitchen, pantry, RV, cabin, or campsite — without needing an outlet nearby.
Does RoboSeal work on both regular and wide-mouth jars?
Yes. RoboSeal's automatic sealing works on both regular and wide-mouth mason jars, from 8 oz spice jars up to 32 oz soup jars.
