6 Best Cordless Rechargeable Dehumidifier 2022

A cheap yet versatile rechargeable dehumidifier that everyone loves. At 8.3 inches width, 9 inches height, 2.9 inches depth, and 1 pound weight, Eva-dry E-333 is the perfect size to bring it around the town. Most people will toss it in a gym bag to soak up all the sweat but you are free to use it anywhere you pleased. At 4-6 ounces of moisture capturing and up 333 cubic feet, Eva-dry E-333 is also well-suited for small storage space like a drawer, watch box, gun safe, under sink, washroom, and laundry room. The built-in hook further enhances its usability where you can hook it to a closet rod and keep your apparel moist, mold-free.

No cut cost measure despite the under 20 budget price. Eva-dry E-333 holds the high quality standard with a leak-proof, spill-proof, and mess-proof body. It is also safe for children and pets with only non-toxic materials used. Adding the industry-leading 5 years warranty and 10 years usage lifespan, you will never have to worry E-333 will break apart with just a tiny bit of knock.

Eva-dry E-333 uses a chemical-free, crystallized silica gel technology that can be safely recharged whenever it is full. After charging, the beads will change from orange to green and you can use the renewable dehumidifier continuously for 20 to 30 days. The silica gel bead contains many interlinked pores that hold moisture up to 40 percent of its weight. With the high holding capacity, there is no need for water emptying, find an electrical source, or rely on batteries to run.

Let's talk about the only 2 negatives here. There is a long charging time that can last between 10 to 12 hours on a monthly basis. You will need an additional standby unit while the mini dehumidifier is charging. The moisture adsorption output is also weaker compared with the higher range variant at only a few measly dollars. Then again, this will be a common theme for most of the renewable dehumidifiers here.

Bottom line: Arguably the best rechargeable dehumidifier in the world. With more than 17,000 reviews on Amazon, you can never go wrong with this.

Eva-dry E-500 renewable dehumidifier is the more rounded, more powerful version of E-333 in lowering humidity and curbing mold growth. At an identical size and weight, it retains the toughness and leak-proof design where no beads will spill out even if you accidentally drop it on the floor. With the higher 6 to 8 ounces of moisture absorption covering up to 500 cubic feet of space, Eva-dry E-500 is highly suited for small areas. You can place it in a gun safe box, pantry, sink, shoe rack, jewelry box, closet, or washroom. For those that are on the move, it will fit in well in an RV cabin, car, boat, or any transport you could think of.

Other highlights of Eva-dry E-500 rechargeable dehumidifier including a built-in hook that you can hang on any rod to dry your clothes. There is also a best-in-class 5-years warranty and a decade long usage life that give you extended peace of mind. Simply put, you can never go wrong with Eva-dry.

Being a cordless renewable dehumidifier, Eva-dry E-500 can run straight for 20 to 30 days without having to find a power source or use any batteries. The beads will hold up to 40% of the water vapor through capillary condensation. You will only need to recharge it once the silica gel beads display indicator turns green. When the silica gel beads revert back to orange, you can unplug the dehumidifier and start using it again.

There is very little thing to dislike about the Eva-dry E-500 rechargeable dehumidifier. It is inexpensive, portable, and more importantly, it can reduce moisture in an enclosed area. Our only gripe is the long charging time that can last up to 14 hours where you will have to left it plugged on. Looking past these two complaints, this is perhaps the most well-rounded dehumidifier on the list.

Bottom line: The slightly more powerful version to Eva-dry E-333. If you don't mind sparing a few extra bucks, this is probably the best version to go to.

Pro Breeze PB-04-US is an affordable, portable, and easy-to-use renewable dehumidifier. The compact form of just 7.3 x 6 x 2 inches makes it the ideal travel-friendly size. You can pack it in a travel suitcase, duffle bag, gym bag, or just leave it in the caravan during a getaway. Pro Breeze PB-04-US can also protect your valuable items like necklaces, watches, electronic appliances from mold and moisture damage. It will silently reduce 5 ounces of moisture up to 333 cubic feet of enclosed space such as a safe box, wardrobe, shoe racks, pantry, and bathroom. Just place it close to your items and it will perform the dehumidification autonomously.

Pro Breeze PB-04-US durability and reliability are top-notch despite the very low cost. It gains all the basic safety features like spill and leak proof where any shock impact will not destroy the rechargeable dehumidifier. Being a cordless model, it is suitable for a home with children or pets without having to endure tripping hazard risk.

Powered by a desiccant crystallized silica gel technology, Pro Breeze PB-04-US is 100% renewable so there is no need to dispose of it when it is full. To recharge the dehumidifier, check the beads through the color indicator windows, if is showing green, it is time to give it a recharge. Find an electrical outlet and let it charge until the beads turn back orange and you're good to go. On average, a completely renewed Pro Breeze PB-04-US dehumidifier will have about 20 to 30 days of nonstop moisture capturing.

Not everything is perfect with Pro Breeze PB-04-US rechargeable dehumidifier though. The moisture output is in a lower range even though the differences are hardly noticeable. The around 10 hours charging time is not something we look forward to as the humidity level will be left untouched during charging. Lastly, the 1-year warranty just falls a bit short when its main competitor's model offered up to 5 years. Still, the drawbacks mentioned do not affect the moisture performance and we would still wholeheartedly recommend this.

Bottom line: An affordable, reliable, cylindrical form moisture absorber dehumidifier that will help preserve your clothes from water damage.

A modern and sleek renewable dehumidifier that will not cost you a bomb. Deerma Electric mini dehumidifier might be the newcomer in this field, it by no means is a subpar product. It is molded with ABS flame-resistant materials that do not overheat and break easily. The food-grade silica gel is also protected by a leak-proof case so you will never have to deal with any spillage mess. Best of all, you can use the Deerma Electric rechargeable dehumidifier in a vertical straight-up position or horizontal position with the help of secure horizontal support. Very user-friendly especially when you're trying to fit in tight compartments like drawers, wardrobe, cabinet, bookshelf, and safe box.

Deerma Electric rechargeable dehumidifier comprises 600g non-toxic porous polymer silica gel beads. With moisture absorption of 5 ounces and up to 333 cubic feet, it can discourage mold and mildew growth while keeping your clothes, gadgets, toys dry. The beads are reusable and refillable so there is no need to discard the unit even when the performance dipped. By looking at the transparent visualization window, you can gauge if is time to recharge when the crystal color turns from pink to blue. A single charge will last you between 2 to 3 weeks of moisture absorption depending on how humid is the area.

Looks can be slightly deceiving. Deerma renewable dehumidifier moisture removal output is actually on par with E-333 despite it seems far more capable. The charging time is also not as quick as advertised despite the thermal conductivity heating base. The standard 1-year warranty covering manufacturing defects is reasonable for its price until Eva-dry industry-leading comes into play. Nonetheless, if you need a modern-looking, rechargeable dehumidifier that simply works, this will do just that.

Bottom line: A rechargeable, cylindrical shape dehumidifier that does what it does best: silently and effectively remove moisture in the air.

The cheapest rechargeable dehumidifier listed here that is unique on its own. HYDROSORBENT OSG-40 Mini Canister is very compact at only the size of a deck of cards. The small 4 x 2 x 0.5 inches dimension will fit comfortably in gun safe storage, jewelry box, toolbox, pantry, and washroom with high humidity. Do not be fool by the low price though, the entire case is made out of aluminum instead of common plastic. It is also proudly made in USA with a lifetime warranty that covers all manufacturing defects. If you need a tough canister that will withstand drop damage or rough usage, HYDROSORBENT OSG-40 can provide you just that.

HYDROSORBENT OSG-40 40 grams crystallized silica gel beads collect moisture up to 40% of its total weight. It is effective at protecting your apparel, photo books, tools, gadgets from rust, moist damage, and musty mold infestation. For such a compact rechargeable dehumidifier that does not rely on batteries to operate, we're more than happy with the performance output.

Here's where HYDROSORBENT OSG-40 renewable dehumidifier differentiates itself from the others. After 2-3 weeks of moisture absorption, you will need to recharge the dehumidifier. Instead of finding an electrical plug, HYDROSORBENT OSG-40 relies on a more conventional approach that uses a kitchen oven to reactivate it. Just place it in an oven, let it baked until the non-toxic silica gel beads revert back to transparent color and it will be as good as new. A safe and eco-friendly approach that would not melt or damage the dehumidifier.

Let's address the elephant in the room. Not everyone likes recharging the mini canister dehumidifier through a conventional oven. The thought of heat mixing with aluminum will drive some away despite it is proven to be safe. Another complaint is the very small dehumidification range that is only meant for a safe box or similar range product. If you're NOT ok with the oven recharging method, this is not the right model for you.

Bottom line: A rare, USA-made renewable dehumidifier that uses the power of an oven to dry out captured moisture. A rare locally made products
