Overview
The Silonn Boost Countertop Ice Maker is a compact model identified by Silonn as SLIM40B-US. The manufacturer lists a 2.5-liter expandable ice basket, a 1.8-liter water tank, two bullet-ice sizes, and a self-cleaning mode. Silonn states that one cycle can produce nine bullet-shaped cubes in about six minutes and that daily output can reach 26 pounds under specified conditions. This review summarizes published specifications rather than hands-on performance.
How it works
Water is added to the 1.8-liter tank, and the machine freezes small batches around metal evaporator posts to form bullet-shaped cubes. Finished cubes release into the expandable basket, and the cycle repeats while water and basket capacity allow. The two size settings change the freezing cycle, while self-cleaning circulates water through the system as part of maintenance.
Key benefits
- Expandable basket is designed to hold more ice before it needs to be emptied
- Countertop format does not require a built-in ice-maker installation
- Two bullet-ice sizes provide a choice for different drinks and uses
- Self-cleaning mode simplifies part of the routine maintenance process

Keep in mind
- Published cycle times and daily output are manufacturer specifications, not WizeBuyer test results
- Countertop ice makers produce ice in batches rather than storing it like a freezer
- The machine, basket, and water system still require regular cleaning and drying
- The unit needs counter space, electrical power, and periodic water refills
Who it's for
A good fit if you…
- Homes, offices, or gatherings that need supplemental bullet ice
- People who want a larger basket than many compact countertop models provide

- Anyone who needs refrigerated long-term ice storage
- Kitchens with very limited counter space or no convenient outlet
Frequently asked questions
Silonn states that it can make nine bullet-shaped cubes in approximately six minutes and up to 26 pounds in 24 hours under specified conditions. Actual output can vary.
It makes bullet-shaped ice in two selectable sizes; it does not make nugget or clear cube ice.
No. The self-cleaning cycle helps circulate water through the system, but the unit, basket, and water-contact areas still need routine cleaning and drying.
