The Tenker 77 oz dehumidifier is a dual fan, dual condenser semiconductor unit for single rooms such as bedrooms, bathrooms, kitchens, closets, RVs, and grow spaces. It collects up to 35 oz of water per day at 86°F and 80% humidity into a 77 oz tank, so you empty it less often than smaller mini units.
A high speed mode handles quick drying, while sleep mode runs under 30 dB. It is designed for one modest sized room at a time, so basements and open floor plans call for one of our other dehumidifier sizes.

Room Sized Humidity Control for Bedrooms, Kitchens, RVs, and Small Grow Spaces
If one room in your house or camper stays muggy, or you are keeping an indoor grow tent from turning damp, this unit gives you more capacity than single condenser mini dehumidifiers without moving up to a heavy compressor machine.
The dual condenser design pulls roughly twice the water of many compact units, and the 77 oz tank means fewer trips to empty it. Its tall, narrow footprint fits along a wall or in a cabinet corner, and the recessed handle makes it easy to move between rooms.
Close the door or zip the tent while it runs, since semiconductor units work best in an enclosed space. Tracking levels with a humidity readout will show you whether one unit is enough or you need a second for another room.
What to Expect from the Tenker 77 Oz Dehumidifier in Real Use
Verified purchasers using it in a single room generally report good results. In a 240 square foot kitchen, an owner saw humidity drop from 70 to 75% down to around 45 to 50%. RV owners say it keeps humidity under control and removes noticeably more moisture than their single fan units, and it has been used in a bathroom without an exhaust fan.
Noise is described as a soft fan sound rather than silent. The lights turn off fully, though the touch buttons stay softly lit. Expectations matter. Several reviewers note it is not suited to large living rooms, and an RV owner estimates a few hundred square feet is the practical range once doors open and people add moisture.
A different owner found it slower than a louder previous unit, describing that as the tradeoff for quiet. One unit did not collect water from the start and was returned. Placing a small fan nearby helps move room air past the unit.

Frequently Asked Questions
How many square feet can a small semiconductor dehumidifier cover?
A semiconductor dehumidifier that collects around 35 oz per day handles a single, modest sized room. In everyday conditions, with doors opening and people adding moisture through breathing, cooking, and showering, a few hundred square feet is a realistic range. Closing the room off and running the unit continuously gives you the best results.
What is the difference between a semiconductor and a compressor dehumidifier?
Semiconductor dehumidifiers use chilled Peltier plates to condense moisture. They are compact, light, and quiet, but they remove a modest amount of water and bring a room to a comfortable level rather than truly dry. Compressor dehumidifiers use refrigerant coils like an air conditioner, remove many times more water, and are built for basements and large areas. They are also larger, heavier, and louder.
Why is my new dehumidifier not collecting any water?
Give a new semiconductor unit several hours in a closed room before judging it, since water collects gradually. Collection also drops when the room is cool or the air is already fairly dry. Make sure the tank is seated correctly, since the unit will not run if it is not, and check that nothing is blocking the air vents. If the room is clearly humid and the tank stays completely dry after a full day, the unit may be faulty and you should contact the seller.
