Quantum power is now lighter, smaller and more convenient. Slip the QB1 Compact under the camera and get 12 ounces of concentrated power. Enough for typically 150-600 auto/TTL flashes (varies with f/ setting), or about 240 shots with a Nikon 950 digital camera. That's four to six times the power of typical rechargeables. And when powering your flash, recycling speed is three times as fast as alkalines and a third faster than nicads.
