The Best Battery Operated Bathroom Dehumidifiers


The Best Battery Operated Bathroom Dehumidifiers

The best battery operated dehumidifier for bathroom areas can be a bit difficult to find, especially if you are not familiar with recent technology advancements in the home appliance market. It can be very convenient to use a unit that doesn’t require cords as they can sometimes be inconvenient obstructions in small spaces where this is not much room to move around to begin with. Additionally, most bathrooms have a limited number of power outlets and you may need to save those for other items that are frequently used like hair dryers, curling irons and other common bathroom items.

However, some people might be surprised to find out that a battery operated dehumidifier for bathroom spaces doesn’t actually use traditional batteries. Yes, they are rechargeable and very energy efficient but they typically rely on silica gels which are small crystals which absorb moisture. As the gel absorbs moisture and becomes full it changes color to let you know when it needs to be recharged.

How to recharge a battery operated dehumidifier?

Recharging these units is very easy and you can typically recharge them in one of two ways. Silica gels, also called desiccants, can be recharged by removing the gel packet from a dehumidifier and baking it in the oven for several hours on low heat. However, some units offer even more convenience and you can simply plug them into a power outlet for 8-12 hours to renew the silica gel.


How long does a battery operated dehumidifier last?

Even though these units do not use traditional batteries they can last for a very long time. Most of the units are designed to last for ten years or even longer. When it comes to how long they can operate on a single charge, they are very efficient. After a single full charge, most units will last from 30-60 days before needing to be recharged again. This offers an excellent level of convenience and makes owning one of these hassle free units that much more enjoyable.

Not only are they great for controlling the humidity level in small spaces but they also make it easy without the need for a lot of maintenance!

Why doesn’t a battery operated bathroom dehumidifier use traditional batteries?

Dehumidifiers require too much power to operate for traditional batteries to be an effective power source. Theoretically, you could use a traditional battery in one form or another but you would end up spending a lot of time and money changing batteries. The silica gel crystals and Peltier technology are far superior if you want a rechargeable unit that is cordless.
