When a space feels “muggy” there’s a lot more going on than just high humidity content in the air. Rooms with high levels of moisture are the perfect breeding ground for pests and mold. A dehumidifier protects your health and your property. Plus, it’s great to step out of a hot shower and not have to wipe the mirror down!
With a dehumidifier, you can cool down a room, evaporate some steam, and even help circulate air. Of course, there are so many dehumidifiers on the market, it can be tricky to know which will work best for your needs.
Things can get even more complicated if the space you’re having moisture issues in has no power outlets or worse, moves—humidity is a real problem in RVs. Let’s take a look at the best portable and battery operated dehumidifiers to help you find a perfect match for your needs.

How Do They Work?
Dehumidifiers work to remove excess liquid in the air. Whether you live in the wet south or have a basement in New England, a dehumidifier can and will create a better quality living environment. Placed in basements, bathrooms, and even boats, they help tremendously without jacking up your electricity bill.
A portable dehumidifier is simply more compact, often has lower energy needs, and is easy to move. It may or may not run on batteries. On the other hand, a battery operated dehumidifier doesn’t run on double AA’s—your control batteries are safe for now— they use a power cord to recharge or “refresh” moisture-absorbing materials.
How long one charge lasts varies, but it’s often at least a few days. Without traditional batteries, these devices run on a variety of moisture-absorbing materials.
Once “charged” the materials have been heated up and dried, letting them start to suck up water all over again. Both portable and battery-operated dehumidifiers are ideal for travel situations, such as RV use.

Shelley Fitch says
When you say that “Most dehumidifiers need to be renewed after twenty to thirty days”, do you mean replaced, as in discarded and a new one purchased? If not, what does that mean?
Many thanks.
Jacob says
Hi Shelley,
I mean once the device reaches capacity (4-6 oz.). This should take anywhere from two to four weeks, but will vary depending on specific conditions. Once the crystals have changed to green, it is ready to be plugged in for 8 to 10 hours in a well-ventilated area. After 8 to 10 hours the crystals will have changed back to orange and it is ready to be used again. The process can be repeated for up to 10 years
