The two in one energy-saving plug we design aims on energy
-saving and electric power storage. We found thatpeople often f-
orgot to disconnect the chargers after theirmobile phones had
been fully charged , when the phones were still drawing electricit-
y from the power source.
Our design solve this problem by storing the run-off electric
power inside the plug, which makes it a potable power for a var-
iety of electronic devices/appliances while it is off-charging.
