Smart & Portable: Battery Operated Dehumidifiers

Last Update:

Moisture is every homeowner’s nightmare. Regular dehumidifiers aren’t suitable for compact areas like closets and gun safes.

That is where battery-operated dehumidifiers come in. However, there are so many on the market that it’s hard to figure out which one is best.

We found the Afloia Dehumidifier to be the best battery-operated dehumidifier. It has a cylindrical shape, so it absorbs water from 360° angles.

Let’s dive in.

The Pro Breeze Wireless Mini Dehumidifier is best for people with mild humidity. It has a moisture absorbing capacity of up to five ounces.

5. New and Improved Eva-dry E-500 Renewable Mini Dehumidifier – Best for Larger Spaces

The New and Improved Eva-Dry E-500 Renewable Mini Dehumidifier is a step up from the company’s E-333 model. It is a little smaller in size than the E-333 and lasts for a range of about one to three weeks. Like other dehumidifiers on the list, it is completely silent when running. This item comes with a five year manufacturer’s warranty.

The E-500’s weight means it charges best when plugged into a power strip connected to an outlet. The E-500 tends to fall out of a normal power outlet. However, the E-500 will likely take up most of the room on your power strip. The rechargeable E-500 is the second product from Eva-Dry on our list and for a good reason. The brand is well-established and known for its customer service.

This item is the best purchase for those with larger areas to keep dry, such as a larger gun safe or closet.

Pros:

  • Long lifespan. The Eva-Dry E-500 runs for up to ten years.
  • The largest area of coverage. It works in areas measuring up to 500 cubic feet.

Guide To Buying Battery Operated Dehumidifier

Battery operated dehumidifiers are often sold at a lower cost. These moisture absorbing units are low on energy consumption and lower humidity. They function in many different ways and control the growth of mold and mildew that accompanies high humidity levels. Many are Energy Star certified, and most are nontoxic. That puts many homeowners at ease, especially if they have children.

Types of dehumidifiers

Refrigerator-Style: This style of dehumidifier is one of the most common types. These take in the air from a room and cool it, dehumidifying it. Then it releases the cool air back into the room. However, they aren’t suitable for cold climates, as they can only cool air to certain points.

Desiccant Dehumidifiers: These are the other most common types of dehumidifiers you might see while shopping. They work by taking in air and passing it over a desiccant material such as silica gel crystals or silica gel beads, which absorb water. They work well in cold climates.

Mini Dehumidifiers: These dehumidifiers are great for small spaces. They are often more affordable and come in corded and cordless versions. Cordless versions plug straight into a power outlet or run on batteries. Many use the same silica gel technology as their desiccant counterparts.

Portable Dehumidifiers: These are pretty self-explanatory. While these dehumidifiers are portable, many still need electricity or an outlet.

What Features to Compare

Size and Capacity

These are the most important specifications to look for when choosing a dehumidifier. You need to make sure the one you’re looking to buy will suit your needs. Dehumidifiers have a maximum capacity of moisture they can absorb. It’s measured in ounces or milliliters.

Certain dehumidifiers also work best when placed in an appropriately sized area. Many dehumidifiers will tell you what sized area the item works best in, measured in cubic feet or square feet. 100 cu ft and 100 sq ft are two different measurements, so it’s important to be precise when you measure your space. A mini dehumidifier won’t do the job if you want to take the humidity from a large room.

Design

You must consider the design of the dehumidifier you’re purchasing. You need to make sure the device can fit where you want it.

Recharge Time

The time it takes battery operated dehumidifiers to recharge varies by brand. Refresh the silica gel beads takes around two to fifteen hours. Invest in multiple dehumidifiers, so you never end up without one when you need it. That will lower the risk of developing mold and mildew.

FAQ

How long does the battery operated dehumidifier last?

The time varies. Most last between 20 and 30 days. However, they will only last for a short time if they are in areas of high humidity. After the product is full of moisture, you must dry out the beads (which “recharges” the batteries).

What are the technologies used in a battery powered dehumidifier?

Most battery powered dehumidifiers use silica gel beads to remove moisture from the air. Air flows through openings and the beads trap moisture. The beads change color as they become wet. Once the beads are completely saturated, heat the silica beads to “refresh” them. This process dries out the silica gel beads so you can use them again.

Where to use the battery powered dehumidifiers in the house?

Use these in a closet, bathroom, small bedroom, storage box, safe, or any small area that needs to be dry. Dehumidifiers powered by batteries function best in areas that are certain sq ft.

Our Verdict

Battery operated dehumidifiers are easy to use solutions for small spaces. They don’t need a lot of maintenance. It’s important to remember what you’re buying the device for and choose one that fits your needs.

The clear winner of the roundup is the Afloia Rechargeable Cordless Dehumidifier. It works everywhere and is portable. It absorbs moisture from all angles, while the others only absorb moisture from one side.
