This dehumidifier is very effective against moisture in confined spaces such as a cabinet, safe, or library. In no case can not be effective for a bedroom or a bathroom: it's not the job! Besides the technical manual clearly states it: "for a volume up to 150 cubic feet" or ... 4.25 cubic meters: 2 m² even for a normal height room, if only 1 m² you have a ceiling height of three meters. This established precisely, the device works well. It is a box filled with silica gel beads as found for example in shoe boxes (those little bags marked "silicate gel, do no eat"). The beads absorb air humidity and store. When saturated with water, they change color and go from orange to green. Just then regenerate by plugging into an outlet. The heat will help to evacuate water (starting between 24 and 36 hours of regeneration). The case may then be placed where it is useful.
At the risk of repeating myself: this camera does not need power to function. Taking only serves to regenerate the absorbent beads.
In conclusion: 20 This little box is entirely satisfactory for protecting your moisture storage.
