But first…

Disclaimer: Cordless rechargeable dehumidifier units are small, so they can only dehumidify a small space. Thus, if you need to dehumidify a basement or other large space, you can have a professional install a whole-house dehumidifier.

How do cordless dehumidifiers work?

Most, if not all of them, work using renewable silica gel technology. They have sachets of silica beads in the drying base.

The unit draws air from the room and passes this air over the beads. These beads capture the moisture, absorbing it while the dry air is released back into the room.

When the silica beads are saturated with water, the unit will show a green light, and you will know that it is time to recharge it.

On a full charge, the portable cordless dehumidifier can last up to 30 days, but most of them do 20 days, which is still fair enough.

Best battery-powered dehumidifier to buy

The goal is to keep the humidity in your room between 30 and 50 percent. Too high humidity has serious effects on your health. Thankfully, today, dehumidifiers come in all sizes and styles, including some really portable and lightweight ones.

Here are two options you might consider:

1. Pro Breeze cordless rechargeable cordless dehumidifier

This is a small, portable, rechargeable cordless dehumidifier. Thus, it is only best for small spaces such as a small office, bedroom, baby nursery, and so on. If you keep it in a large room, you will not find it very effective.

Pro Breeze cordless dehumidifier space rating is 333 cubic feet

To prevent mold from forming in the closet and damaging your clothes, you should use this dehumidifier. Just put it in the closet! It will do a great job.

If you have a small attic, you can use this dehumidifier. Mold forms in such places, and it can cause serious sickness when the mold spores start floating around.

Long-lasting battery on one charge

On a single charge, this dehumidifier is going to dehumidify your indoor air for up to 30 days. Of course, it depends on how often you run it.

Many people do not run their units throughout the day. Usually, a maximum of 7 hours is enough, even in places like Florida, which have high humidity.

Even if it lasts only 20 days, the fact that you will not have cables cluttering your place all over is very nice. It is worth it.

What really happens is that when the silica gel has absorbed up to 5 ounces of water, it needs to be regenerated. You do that by plugging in the Pro Breeze unit and recharging it.

It uses silica gel technology

To be precise, this dehumidifier uses renewable silica gel technology. This means there is a sachet of silica gel that is chemically inert. It does not exude toxic gases and is safe around kids and pets.

When you switch the dehumidifier on, the humidity light indicates orange, meaning that the silica gel beads are dry and ready to absorb moisture if humidity is high.

If the humidity lowers and the silica beads become saturated, the light turns green. This means it is time to recharge the dehumidifier again.

This is a very lightweight unit. It weighs slightly less than 1 pound. Thus, you can transport it easily from place to place.

You can use this battery-powered dehumidifier for a car, camper van, motor home, closet, small office, and other small spaces.

2. MXRJUWM Wireless: Small battery-powered dehumidifier

This is the best stack of rechargeable cordless dehumidifiers that you can use for small spaces. There are so many good things to love about this unit.

All-round ventilation

First, this unit collects air from all around it. It is ventilated all around, so it can do a faster job than dehumidifiers that pull in air from one side only.

If you need to dehumidify a small space faster, you can use it. Due to its small size, it is perfect for dehumidifying closets, RVs, camper vans, kitchens, bathrooms, and other small spaces.

Uses silica beads to trap moisture

The dehumidifier uses silica to absorb moisture. With this technology, you do not need a dehumidifier compressor, which makes the unit heavy.

When the silica gel becomes saturated with moisture, you can recharge the unit. This rechargeable cordless dehumidifier needs only 2 hours for a full recharge. On a full charge, it can last you up to 3 weeks.

The space recommendation for this small battery-powered dehumidifier is 340 cubic feet. If you use it in a room bigger than that, it might not lower the humidity to the required level fast enough. You can reuse the dehumidifying base (with the silica) up to 300 times.

As a 45-watt dehumidifier, this is not going to increase your electricity bill too much. You can refer to our article on do dehumidifiers use a lot of electricity to see what we mean.

Overall, this unit is great and does what the manufacturer says it can do. Remember to order the unit with the heating base rather than the top only.

Those two rechargeable cordless dehumidifiers will give you more than enough value for money. The quick charging time makes this one a winner.
