I don't usually use the one Fuel Rod I own as I have several higher capacity Anker power banks that I bring to the parks. However, there was one long day where I forgot any type of power bank and it wasn't convenient to leave and try and buy one outside Disney. So I bought a Fuel Rod out of desperation and found it charged incredibly slowly. I know the point is you can swap out for free. But it required so many swaps to get two phones through the rest of the day, I just found it a bit of a drag to use.
But anyway, I'm not trying to start a Fuel Rod debate lol (If you love yours, awesome!) This is just a long-winded way of sharing that the Fuel Rods have been updated with better charging capacity. This also means the cost to buy a new one has gone up. But the upside is if you do already own one, you can swap as you usually would at the Disney Fuel Rod kiosks, and receive the new upgraded one now instead, along with a new cable kit. So even if you use it infrequently, might as well switch it out for the new version!
