Fuel Rods. The last battery backup I bought died after my first trip with it, and I never got around to replacing it. After hearing some chatter about the Fuel Rods from members of the DIS crew, I decided to give it a try. I wasn't really optimistic about such a small battery being able to recharge my Samsung Galaxy Note 4, which is a big smart phone, with a big battery, but I tried it anyway. It turns out that the tiny little Fuel Rod is capable of bringing the monster battery in my Note 4 from about 35% up to full, which is an impressive feat. The Note 4 battery is 3220 Mah, not a small battery by any means.
However, the best feature of the Fuel Rod isn't it's capacity, it is the ability to swap it out for a fully charged replacement battery, for free, any time at the park. This is the feature that inspired me to buy the Fuel Rod to begin with, and it is all that I thought it would be.
I purchased the Fuel Rod in Magic Kingdom, and immediately put it to use charging my phone, then went looking for a kiosk to swap it. There is one in the Theater building in Town Square, just inside the doors to the right, another at Pecos bill, one at the gift shop outside Space Mountain, and a fourth one at Petes Silly Sideshow. That last one, at Pete's, is the only one we didn't visit during our trip. The remainder of the kiosks in MK we used at least once each. That first day, the battery recharged my phone, then we swapped it and charged my sons phone, then another swap, and a recharge for my daughter, and one more swap before topping my phone off again.
In EPCOT, a similar pattern. Kiosks are in the camera shop just inside the park, in the gift shop to the left at the entrance to World Showcase, and at the International Gateway. We used all 3 of those locations, and charged multiple phones during our time in the park. We also swapped for a fresh Fuel Rod once at the Polynesian resort.
Now then, IF . . the Fuel Rod had to be judged solely by it's capacity, it would be a dud. There are tons of battery packs out there that could put a full charge on my phone 2 or even 3 times before needing to be recharged. The Fuel Rod can't do much more than 65% before needing a recharge. However, it does not need to be judged by it's capacity, because as long as you can swap it for a new device, it essentially has unlimited capacity, and this makes it an amazing investment.
I do have some question as to the long term stability of this business model. Eventually these batteries will start to age, and need to be replaced, and with all of the owners being able to simply swap for new ones at any kiosk, the cost of replacing the aged, and useless batteries will fall upon the Fuel Rod company. I fear that this means essentially, that their business model is like a pyramid scheme, and once those replacement costs creep up on them, the Fuel Rod company might simply vanish, leaving us all stuck with useless Fuel Rods. However, for $30, just getting through one vacation with it, I feel as though I've gotten my money's worth. If they are around long enough for me to use it for a second vacation, even better. I paid more than $30 for the last battery bank I had, and that only made it through one trip, so even if this company does ultimately go out of business, this was still no less a value than buying a bigger battery bank elsewhere.
All things considered, I would have to say that this is a great product, very useful, and I hope they are around for many vacations to come!
