Does the job, very well actually

Because I use a few different Flash Diffusers, on a 580EX II, they tend to drain the batteries pretty quickly. The CP-E4 Battery pack, fixes that problem. The increased recycle time is also a nice feature. I use rechargable AA Batteries in it, and there replacement cost is better, than with some other packs.

I made a scan of it, and will include it here. I have not encountered any problems with it, following the instructions.

Canon CP-E4 Battery Pack

the tabs which hold the AA batteries are VERY fragile and break off easily. You need to push the batteries from behind to get them out without damage. The battery frame is replaceable, however, so you can survive if too many break off.

Meh

By

from State College, PA  -  Pro Photographer

The limiting factor with flash seems to be the heat buildup on the strobe, itself. Having this external pack certainly gives you more battery life, but the main reason that I bought it was so that I wouldn't *literally* fry my flash unit when shooting wedding receptions. I had lithium AA's in my 580EX-II once, and they got so hot they actually melted the plastic inside my flash, along with frying the electronics. External power helps with that...but you still can't shoot more than about 20 flashes in a row, because the flash head still gets hot. Worth it? I don't know, but at least I can sleep better knowing that the batteries won't melt the inside of my $600 flash! As for the unit, itself, it's a bit cumbersome and has some design flaws. Having that coiled cord attached is annoying, because it's too short and gets in the way. Be careful with this thing, because the batteries don't snap into the cartridge. That is, if you turn it upside down, half your batteries fall out. You could never keep a spare cartridge full, ready to swap out. Remembering to "keep this side up" during an event where you have a thousand things on your mind is tough...bad design. Last, but not least, it's a real pain to tell your speedlite to use external power only. You need to manually switch that in the custom functions, which is not exactly convenient. No reason the speedlite can't this auto-sense the presence of the CP-E4. Come on, Canon! All in all, this could use some updating. Bottom line? If you are looking to stop swapping out batteries over a long period of time, this will do the trick. You might get a whole day's worth of flashes out of it. However, if you want rapid flash recycling, this will do it, but you will still encounter heat build-up in the strobe, which kind of defeats the purpose. This will keep the internal batteries from getting too hot if you switch your strobe to external power only.

Can't do without this device

By

If you shoot weddings and worry about your batteries dying then purchase this device. I have shot over 850 photos and still had plenty of power left. Get peace of mind and buy this device you won't be sorry.

Power Reserve and Longevity

By

from Severn, MD  -  Semi-pro Photographer

Allows the event photographer more time between battery changes when using a speedlite. And with batteries in the speedlite and the attached battery pack the recycle times seem quicker. I've notice less "non-firing" flash images in rapid fire situations.

Great refresh time

By

from Madison, WI  -  Semi-pro Photographer

This battery pack does take an additional 8 batteries to fill, plus the four in the flash, for a total of 12. But that means you are able to have a lot faster recharge time. I can use this with a 7D at 8 fps if I have the flash dialed down to around 1/8 power. I tend to use the flash as more of a fill, but on full power recharges, the time is greatly improved too. I like know I am not going to miss something because my flash is recharging.

Works exactly like the CP-E3. I bought as a replacement. Seems nice and sturdy and works fantastic. Can't go wrong.

Like it so much, I bought another

By

from Bridgeport, CT  -  Semi-pro Photographer

I like this unit so much i purchased another one for my son. Now, I'll have to buy him a Canon speed light to go with it.(He has a 4 series speedlight that doesn't accept ths unit... that would be my only complaint about it) The unit has to be connected to the flash to turn on, as there is no off-on-switch. Which is fine with me. Want to turn if off.. turn off your main unit, or simply disconnect it from your flash. I also like the fact that I can use both recargeable and non rechargeable batteries in it. I've taken as many as 500 shots with it, and still had power to spare. Be sure to set your flash to CF setting that permits the batteries in this unit to be exhausted before the ones in your flash. In this way you'll have a reserve to work with before completely running out of power. Wished that Canon made this compatible with the 430 ex as well. It's so cost effective when compared to alternatives.

Convient and lightweight

By

from CT  -  Semi-pro Photographer

When shooting high school football, this is attached to my monopod to power my 580II. Changing the battery clip is easy and I suggest you buy a second clip. The only complaint is that in cold weather the recycle time is slower than I like

OK for the price/size but not a Quantum

By

from Los Angeles, CA  -  Pro Photographer

For the the size it's OK, knock at least $50 off the price. It's definitely not as responsive a a Quantum pack but good enough to get thru an event at about three consecutive flashes if your bouncing light, you may get more for direct flashes. I wouldn't recommend it for press functions like a step and repeat red carpet stuff. For the amount of gear I carry for the size and weight it's worthwhile.

Absolutely necessary for coutinous burst

By

from Florence, NJ  -  Pro Photographer

Canon made a great improvement on the CP-4 magazine battery clips (over the CP-3)and thus I now have a very reliable unit for my 550 & 580 XE II flashes. If you want to shoot continous burst w/flash you need this unit. I shoot a lot of indoor sports and activities such as dance routins where sequential shots are necessary. This unit has never let me down, and the light weight makes it easy to carry for long periods of time. The only improvement I can think of would be a belt clip instead of the belt loop
