Ice Artisan‘s best picks
Do portable ice makers keep ice frozen?
No, most portable ice makers do not keep ice frozen for extended periods. Unlike refrigerator and undercounter ice makers, the portable countertop ice makers lack the actively cooled storage compartment in their storage bins. Actually, the portable ice makers are designed with rapid ice melting in mind, so they can quickly make ices again.

I will try to describe the core function of a portable ice maker. Countertop ice makers deposit cubes into a small insulated reservoir without any additional refrigeration. This bin is well-insulated in some models, and bad-insulated in many no-name Chinese models you can find on Amazon. It isn’t a freezer, so even in the best countertop ice maker, if you don’t take care of the existed ices, it will melt over time and drips back into the reservoir to be reused in the next cycle.
If you just want an ice-ready ice maker that doesn’t repeat the ice making process, you must buy an undercounter ice maker. I make a list for the best undercounter ice maker, just in case you change your mind. I also write a helpful article to distinguish between countertop vs undercounter ice makers, make sure you will read this article to know which is more suitable for your home.

Conclusion
While portable ice makers are good at rapidly producing ice, they aren’t designed to keep ice frozen. I know it is quite disappointing for many people, but hey, you can run the countertop ice maker for short time, collect the prize, then store it in your kitchen and save energy. I think it is economical, right?
