Compact Battery Pack CP-E4 – a pocket powerpack for flash
Batteries in your Speedlite 580EX II, MT-24EX and MR-14EX flash units will usually provide more than enough power for most uses but sometimes you want to take lots of pictures with flash, the flash needs to recycle really quickly, you might want to use a high power burst of flash frequently. The Canon CP-E4 battery pack provides an extra power source to help you to do this.
Who is it for?
Any photographer making use of flash extensively should consider the CP-E4. With eight AA batteries, it will help the flash to recharge even quicker and will give you more flashes between battery changes.
- Eight x AA batteries for longer life
- Faster recycle times for the flashgun
Clever use of Speedlite flash can really improve your images but they run on AA batteries and, in high-power situations where you are taking lots of pictures, they can run out quickly. The CP-E4 provides an external power source for the Canon Speedlite 550EX and 580EX flashgun ranges to give faster recycling and more flashes between battery changes.
On the 580EX range of Speedlites, a custom function can be set to determine whether the flash recycles from both the batteries internally and the external CP-E4, or just from the external unit.
- Weather sealing
The CP-E4 is as weather sealed as the Speedlite 580EX II flashgun and will maintain the weather sealing of the unit around the joints.
