Short answer
To recharge the Eva-Dry E-333 Mini Dehumidifier, wait until its indicator beads turn green, then fold down its hidden plug and plug it into a standard outlet for about 10 to 12 hours, until the beads return to orange. Eva-Dry's manual says to keep 24 to 36 inches of open space around it while it renews and not to leave it plugged in for more than 18 hours. It takes no refills.

What recharging the E-333 involves
The beads tell you when
The E-333 uses color-changing moisture beads as its indicator. Eva-Dry's manual says green beads mean the unit needs to be renewed, and suggests checking them roughly once a month (every 4 to 6 weeks) for the change from orange to green.
It plugs straight into the wall
The plug is part of the unit: the manual says to fold down the hidden plug and plug the unit into an outlet. Eva-Dry lists the power as 110-120V, used for recharging only.
Plan for about half a day
Eva-Dry gives a recharge time of approximately 10 to 12 hours. The beads returning to orange is the sign it is renewed; then you unplug it and put it back. The manual says not to leave it plugged in for more than 18 hours.
Nothing to replace
The E-333 absorbs moisture with renewable silica gel. Eva-Dry's product page says there are no refills and no disposable components, and that you just repeat the cycle as needed.
How to use it
- Check the indicator beads roughly once a month (every 4 to 6 weeks). When they have turned green, the unit needs to be renewed.
- Fold down the hidden plug and plug the unit into a standard outlet, in a well-ventilated spot with 24 to 36 inches of open space around it. Do not cover it or hang it from hooks while plugged in.
- Leave it plugged in for about 10 to 12 hours, until the beads return to orange. Do not leave it plugged in for more than 18 hours.
- Unplug it and return it to use.
