How does the KingBin™ auto-seal the trash bag?
Inside the KingBin™ Ultra is a sealing element built into the SmartRingTM system. When the bin is full, hold the button for 3 seconds. From there the lid lifts automatically, and the SmartRingTM tightens the bag, then uses heat to fuse the bag closed at the top creating a clean, airtight seal.
There's no twisting, tying, or touching required. Once sealed, the bin preps a new one to load, ready for the next use.
How long does the battery last after a full charge?
The battery lasts up to 50+ days with a single USB-C charge. Nearly two months of not thinking about your trash... exactly how it should be.
Do I need special refill bags?
Technically yes.
KingBin™ uses Smart refills that auto-seal and reload your trash bags. It's how the magic happens. And to make your life easier, we include a 1-month supply right in the box.
How easy is it to install new refill rings?
Super easy! Lift the lid, pop in the Smart Ring, and you're ready. Takes less than 10 seconds.
What if I run out of refill rings?
We include a 1-month refill supply with every bin. If you run out, our support team is ready and our refills ship fast in 2-5 business days with Free Shipping.
