I know there’s that rule about over-charging your gadgets or draining the battery first before you charge (or NOT draining the battery before you charge) lest you want to shorten the lifespan of their batteries. Personally, I have a habit of just leaving my gadgets plugged until I’m ready to use them (or more often than not, when I remember to unplug them). Now you can be reminded not to overcharge you gadgets with the Dialug.
The Dialug is a plug that turns (like a dial) and becomes a timer of sorts. Just turn it counter-clockwise to power sign to set for regular use and clockwise to set timer for gadgets that need only limited time of power. Designed by DanBee Lee, JangSoo Kim, KyoYeon Kim & WooRi Kim, the Dialug is an iF concept design entry and an eco-friendly solution to accidental waste of electricity.
