This rechargeable dehumidifyer absorbs excess moisture from the air. This product is a great option to help reduce condensation build up when either storing or using your TentBox. It's also a great option if you're leaving your TentBox on all year round - just pop the bag in when the TentBox is closed, and give it a recharge every now and then.
How to recharge
To recharge either pop it in the microwave on a low power setting for a few minutes, leave it to dry near a radiator, or leave it overnight in an airing cupboard. The blue circle indicator will turn red when the bag needs to be recharged.
