Mini USB Air Dehumidifier

As a chef I deal with humidity all the time in my kitchen and at home with kids things get musty fast. I had mold starting in a small cabinet and needed a fix without spending much. Found this CosyHome dehumidifier online did some research and decided to try it. Plugged it in via USB in the cabinet and within a day the air felt drier no more damp smell. It worked great for that spot but in my slightly bigger pantry it struggled a bit. Emptying the tank is easy just pour it out but I have to do it daily during humid weeks. Overall it solved my main problem and for the price it's a decent buy just keep expectations realistic for small spaces. Would recommend with caution for targeted use.
- Pros: This thing is extremely effective at pulling moisture out of the air in small areas like my closet or the bathroom where dampness was a constant issue. I liked that it runs off a simple USB connection so I can power it from any port around the house and it's so quiet I barely notice it running even at night. The automatic control means I don't have to fiddle with settings it just does its job on its own.
- Cons: The water collection part fills up pretty quickly in really humid conditions so I have to empty it more often than I'd like which can be a bit of a hassle. It doesn't cover larger spaces well at all so if you have a big room this isn't the right pick. Also the build feels a bit flimsy to me not something I'd trust long-term without care.
