It appears that the Fuel Rods have been quite popular at Walt Disney World. These are portable chargers for electronic devices. They cost $30 and you can come back to one of the kiosks and swap and unlimited number of times to obtain a freshly charged portable charger. You can also recharge them yourself in order to use them again. With the popularity of the kiosks and the level of effort for the cast members to keep the kiosks stocked, it has been reported that Disney is adding another 15 kiosks around Walt Disney World. It is no surprise that this service gained such popularity and we expect this to likely remain a staple at Walt Disney World for a while.
