Lighter, smaller and more convenient. Attaches to tripod socket on bottom of camera. "Fuel Gauge" displays power remaining and charging level. Energy saver mode dims lights for longer shoots.
"No-memory" nickle metal hydride cells charge reliably in 3-4 hours. Outputs for both short (Bantam "X" series) and long (QB1/1+ "M" series) cords. Four to six times the power of typical rechargeables.
Enough for about 240 shots with a Nikon 950 digital camera, 800 shots with Kodak 265, or 400 shots with Olympus 620L. (With the LCD off). Recycling speed is three times as fast as alkalines and a third faster than nicads.
