It's no secret that digital cameras and flashes are power hungry — look how many times you have to replace or recharge your batteries. To end this energy crisis, Quantum has created the QB1 Compact Battery that delivers four to six times the power of typical rechargeables. For flash, recycling speed is three times as fast as alkalines and a third faster than nicads. All this power is concentrated into an extremely lightweight, compact 12 oz. (340g) battery. The QB1 Compact easily attaches to the tripod socket of most digital and traditional cameras or can be worn on your belt with the convenient belt clip (included). The "Fuel Gauge" displays the power remaining and the charging level and when powering your flash, recycling speed is three times as fast as alkalines and a third faster than nicads. Recharges in three to four hours.
