Batteries in your Speedlite 580EX II, MT-24EX, and MR-14EX flash units usually provide more than enough power for most uses. However, if you want to take many pictures with flash, the flash needs to recycle quickly, and 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 achieve this.

Who is it for?

Any photographer making extensive use of flash should consider the CP-E4. With eight AA batteries, it will help the flash recharge even quicker and will give you more flashes between battery changes.

Key features

• Eight AA batteries for longer life
• Faster recycle times for the flashgun.
