Wish they’d put in a few machines in the parks & onsite hotels.
We do travel with the WDW one plus at least another small & a larger. At times it’s difficult to grab a charging pug at airport and when there’s a delay, it’s nice to be able to watch a movie, etc.
We rely on them at WDW and airports I fly thru tend to have the machines (where it’s cheaper to buy the rod).
Have noticed the juice can be hit or miss when we’ve exchange it the last few trips. No biggie, just hit up the dispenser again.
