The Eneloop Pro comes in packs of two or four batteries with a portable wall charger, with pricing starting in the $15-20 range. Sanyo suggests that these make a good choice over standard rechargeables especially when used with high-powered portable devices, like cameras, their flashes, or even flashlights. This battery has a black casing to distinguish it from the Eneloop Plus, an identical version save for an added heat sink that prevents overheating.
