Sure, go to the hardware store and buy a 12 gauge extension cord of the required length. You can make yourself one if you wish. Buy a male and female end and some 12/3 cab tire (sjoow or soow) off the rack at the hardware store.

The voltage you measured is acceptable. The utility usually guarantees +/- 5% @ 120v.

Cheers, Brendan
