Portable Power With The Swedes - Profoto
This is the best battery-powered flash pack we have ever seen. It has the usual features of a studio pack - 1000w/s power, two exit ports, 1/10 stop power control with digital readout, etc. but it adds the following delights:
1. Very high speeds indeed:
The pack will fire up to 30 times per second.
It will fire and then recharge in as little as .03 of a second on low power settings. Even at full boom
it only takes .99 of a second to be ready again.
The discharge from the flash heads attached can be as short as 1/25,000 of a second. Wow.
2. The battery can provide up to 220 shots on full power. Of course as it it is a rechargeable Li ion pack it can be trickle charged - the specifications state that this is a 45 minute task from fully discharged. But consider - the trickle charger is a fast one ( perhaps it should be called a pouring-stream charger...) and the pack can be used in a studio setting connected to the mains as if it was purely mains-powered. It just keeps shooting continuously.
The batteries for this unit are also certified with the appropriate approval for domestic and international flights - an important consideration when faced with airline red tape and tight schedules.
3. As the name specifies - the B4 1000 Air is ready to go for the wireless synch system. Profoto controllers are particularly easy to use on the camera - they have deliberately made them user-friendly so that you do not need to fight them while you are trying to conduct a busy shoot.
As with all Profoto gear, this is made to a very high standard indeed - aluminium chassis and rubber covering for field ruggedness - extremely rugged connector points - positive switches and indicators - no guessing as to which setting something is on. It fits right in with the Profoto heads and light shapers.
* As with all Swedish products, the information came in a flat pack and it was assembled with a small Allen key.
