Modern digital cameras are almost always powered by rechargeable lithium ion battery packs instead of store-bought AA batteries. This is great for your wallet since traditional AA batteries are expensive and don’t last long in today’s powerful digital cameras. However the downside to lithium ion battery packs is once they’re drained you can’t just run to the convenience store and buy another one. This means that when your battery pack dies you might be done with your photography session for the day if you don’t have access to an AC outlet. The Sakar CH3400P Universal Travel Battery Charger solves this problem by allowing you to recharge your camera battery using your car’s 12V DC socket. This charger is compatible with Fuji and Pentax camera batteries.
