Why Do You Need A Battery-Operated Dehumidifier?

The high amount of moisture and humidity is bad for human health as it causes dehydration, muscle cramps, etc. where dehumidifiers do a great job. While many homeowners will opt for large and central dehumidifiers, these machines are often costlier and don’t reach every corner at home or office.

The real concern that most homeowners show is that battery-powered dehumidifiers aren’t effective or at least less effective than their whole-house counterparts. However, this is far from the truth since even the cordless dehumidifiers are as effective as the regular ones, if not more.

First off, cordless dehumidifiers are inexpensive, portable, and easy to control. Hence, you already know they are better for confined spaces.  Secondly, their working procedure is the same as any standard dehumidifying machine in the market except that it uses a battery instead of direct electricity as its power source.

Most of these machines come with digital controls. So, you can quickly set the level of dehumidification you want in a specific space. Plus, they are compact and need less space in the room. You will also find their installation and maintenance faster and easier than corded ones.

Therefore, it is easy to say that rechargeable cordless dehumidifiers are not just effective. In fact, it is a better option than standard dehumidifying devices. And when you count its quieter operation, there’s no match to the effectiveness of the battery-operated dehumidifiers.

How Does a Battery-Operated Dehumidifier Work?

A battery-operated dehumidifier with its quiet and portable operation is a healthy and economical addition to any home. Plus, the dehumidifier comes with a unique way of working without using AC electricity.

  • The construction and design of cordless dehumidifiers are pretty conventional. Most manufacturers use ABS plastic to make the device. The battery is mostly lithium-ion made, and the device comprises the coil, fan, and tank for storing water. Also, the dehumidifier has crystalized silica beads which are reusable with the battery charging facility.
  • Inside the dehumidifier, a strong motor and a fan draw the bulk amount of moist air from the exterior. Then, it goes through the silica beads to absorb the moisture, and then the dehumidified air is released back into the air. The tank collects the excess water, and you will have to empty it whenever it gets full.
  • Unlike the whole-house humidifiers, the cordless dehumidifiers often lack any display. So, you won’t see any humidity level on it. Nonetheless, the dehumidifier comes with a warning for a tank full and when the silica beads need recharging. The signal will often turn from orange to green to alert you about the possible emptying and recharging necessity.
  • The battery will last for a couple of days to weeks even. When recharged, the materials are dried and are ready for use. So, it also serves economic purposes.

How to Get the Best Battery-Operated Dehumidifier: Buyer’s Guide

Our review for the cordless dehumidifier includes top choices from experts and customers. You can simply pick the one that best fits your requirements. But how do you determine which dehumidifier will work best for you?

Well, the following factors will help you get the best cordless dehumidifier that doesn’t need AC electricity:

Water Removal Capacity

The goal of using the dehumidifying device is to absorb the additional moisture from the air. Hence, you have to look at how much water it can collect from the environment. It is often rated in oz or ml and is determined by daily capacity.

Ideally, a dehumidifier with 350-500ml water-absorbing ability is ideal for medium rooms. Most of our reviewed devices collect around 350ml water, with the highest capacity having 2000ml capacity. So, it will fit your necessity.

Space Coverage

Decide how much space you want to cover to remove the humidity? A standard mid-sized room will be around 200-250 square feet mostly. So, you have to choose a dehumidifier that can at least cover 200-250 square feet of space.

Tank Capacity

The tank capacity will determine how frequently you have to empty the water tank. If it is too small, you will need to empty it too frequently, which can be tiresome and frustrating. And this is the last thing you would want.

So, look for a dehumidifier with a large tank capacity. Ideally, the tank capacity needs to be 2X more than its moisture absorbing capacity. For instance, if a dehumidifier can collect 350ml water per day, its tank should hold 700ml water. It will require less emptying.

Charge Duration

Since these dehumidifiers are all battery-operated, the charging duration of the battery is important. It will also determine how long the reusable crystalized silica beads can work with a single charge. The higher the charging duration, the better the convenience will be.

If a dehumidifier needs charging once every 3 to 4 days, it is undoubtedly tiresome. We only included those dehumidifiers that can work for 20 to 30 days on a single charge.

Recharging Time

The last thing you won’t want is to wait for the entire day to recharge the battery. Hence, you have to look at the recharging time of the dehumidifier’s battery. Also, a long recharging time means you will get less service from the dehumidifier.

We suggest you get a device that can recharge the battery within 304 hours maximum. If it extends up to 6 hours, it will be a waiting game and may frustrate you.

LED Indicators

Even though the best battery-operated dehumidifiers are compact, it still needs to be user-friendly and convenient. One such convenience is the LED indicators. It will warn you when the tank is full. Also, the LED indicator will help you know the silica beads that will need drying and recharging.

When the indicator turns green to orange, you need to recharge and bake the silica beads for reuse.

Silica Gel Beads

The battery-powered dehumidifiers work with silica beads to absorb the excess water from the air. The beads must be reusable and toxic-free. Also,  it should be free from any harmful chemicals and elements for health-safe usability.

Also, check the surface area. Bigger beads will have bigger porous, absorbing more water from the air for a comfy ambiance.
