A single charge supports 18 hr. of continuous working...leaving your camera battery to do what it was designed to do! But, when the power close to run out, it will automatically switch to use your camera battery as backup...so you can keep right on shooting!

The GMAX is always on standby it reacquires its satellite signals in seconds, not minutes! Feeling "Up in the Air"?
