There are plenty of battery packs available to help you keep your devices juiced up whilst away from the grid, but most take an age to charge your smartphone to full capacity, but not the Buffalo Voltissimo.
The Buffalo Voltissimo battery has been designed to charge an iPhone from flat to full in just 15 minutes, and is equipped with a 4000mAh or 8000mAh battery depending on your preference and budget.
The large Buffalo Voltissimo 8000mAh battery is capable of re-charge an iPhone 4 times on a single charge, helping you keep your smartphone going for those longer periods away from a charging socket.
Once the Buffalo Voltissimo battery is flat, even it recharges quickly and only takes 47 mins to charge the 4000mAh version and twice as long to charge the 8000mAh Buffalo Voltissimo.
The 4000mAh Buffalo Voltissimo is selling for around $190 in Japan, but no information has been released as yet on worldwide distribution dates. But as always we will keep you updated if we hear anything.
