I like to use the Seeker's Star, Magic Folio for XP, Magic Ingot for coins, and a Fire Crystal for power, since they're all 2 hr talismans. Then it only takes going back and forth two or three times (depending on your maximum energy cap) to fully recharge. I may have to use up some of my SOVs though. Right now I'm sitting on stockpile of 87! 😃

You can gain energy by moving back and forth in the window without using a talisman, but it can be a bit of a drudge. It just depends on your individual time and resouces.
