Welcome to planDisney, Jessica, and thanks for this
shockingly interesting question. My phone wouldn't last past lunch if I didn't have a portable charger at the theme parks, so let's look at what's allowed inside the
Walt Disney World Resort.
I spoke to an
electrifying Cast Member who said a battery bank like the one you mention will probably be allowed inside the theme parks. Depending on the specific one you have, it will be up to the discretion of
security personnel when you arrive.
After doing an online search, I feel your size battery bank will most likely be acceptable, and I might order one of those myself! I suggest you have your phone charging cables with the battery bank to show how you intend to use the device, and be prepared to return it to your car or Disney Resort Hotel if security doesn't allow it for any reason.
I love the
Portable Phone Charging System I purchased at Magic Kingdom Park. These kits can be found at all four theme parks,
Disney Springs, and some Disney Resort Hotels.
After buying the system, you can switch out a depleted rod for a fresh one at no charge at any Walt Disney World Resort kiosk. You can find locations on the
My Disney Experience Mobile App by clicking the pin icon at the bottom of your screen and sorting by Guest Services. Tap the "List" option at the top right and scroll to "Portable Phone Charging System Kiosks" to find these handy vending machines.
Jessica, I'm sending pixie dust and lightning bolts so you'll have a
powerfully good time on your upcoming visit. Please
stop by planDisney anytime!
Magic awaits,
Elaine
