The Profoto Pro-B4 1000 Air Pack with Battery and Charger supplies 1,000W/s of portable flash power in a compact, 21.6 lb package, with the most advanced long-life battery (LiFe) now available. The Pro-B4 Air gives you everything you want in portable power; up to 220 flashes at full power, super fast recycle time (0.03 - 0.99 sec.), flash durations as short as 1/25,000 sec., and flash variability over a range of 11 stops (1.0-1,000Ws). The LiFe battery gives you up to 4 times the battery life of previous batteries while the built-in Profoto Air radio sync receiver provides remote triggering control from up to 985' (300 m) away.
The Pro-B4 Air has been tested, certified and licensed for travel according to the UN manual of Test & Criteria, Part III, Sub-section 38.3 and the included multi-voltage charger allows you to charge the battery on virtually any AC current, ensuring that you'll be able to work anywhere in the world.
Extremely Short Flash Durations
With flash durations as short as 1/25,000 sec. it is now possible to freeze motion in a way that yesterday's photographers could only dream of
Exceptionally Fast Recycling
The Pro-B4 is one of the fastest recycling battery generators on the market. At lower power settings it is able to fire up to 30 flashes per second, while the longest wait on full power is less than a second. In other words: you will never have to wait for the Pro-B4. Now how fast you can shoot depends only on your camera
The solid-cast aluminum chassis and the sturdy rubber frame ensure that the Pro-B4 can take a beating. All connections are covered with protective lids, helping to prevent moisture and dust from entering the generator
Powerful Inside and Outside the Studio
On-location, its performance rivals that of any mains-powered studio generator. In the studio it gets even better. The battery can fully recharge in less than 45 minutes and can be recharged while in use. This means that if the modeling light is used moderately, the pack can be used continuously
Tested and certified according to UN manual of Test and Criteria, Part III, Sub-section 38.3
