There are several options for replacing a lost or out of warranty charger. You need two parts to make a working charger: an adapter and a line cord.
The adapter will have a description similar to 45W,20VDC,2P,WW,DEL. Lenovo Part #'s compatible with your computer include: 00HM612, 00HM614,00HM616, 00HM625, 00HM62, 36200281, 45N0292, 45N0296, 45N0300, 45N0473, 45N0474, 45N0475
The second part is called the line cord. A 2 prong cord as a part number of 42T5008 and a 3 prong cord is part number 42T5004. The 2 prong line cord is the most commonly one used with the yoga 11e computers.
