420EX external power supply?

[john_davids]

can 420ex use an external power supply (in effect turning it in to a mono

light). This would of course be off camera.

No officially, but there are DIY solutions such as <a href="http://burren.cx/photo/flash_power.html">this</a>.

I like that idea. I would probably end up splicing in a 6v AC Adapter instead, but i do like it. Thanks for the link

I noticed the 550ex is set up better for external power... would hooking this flash up to an AC source be easier than hooking up a 420ex?

Probably not. At least I haven't seen any AC power supplies for the 550EX/580EX high voltage port.

 

But one thing the 550EX/580EX Speedlites will do is allow you to use Canon's CP-E3 ($140). It still uses AA batteries (12 of them counting the four in the flash), but it recycles your flash far faster than would ever be possible for a 420EX/430EX and does so for hundreds of shots. I used it for one wedding where I took over 700 flash shots and the NiMH batteries never slowed down. In fact, I've never run out of power with it at a wedding. And since it's portable you don't have to go looking for a AC power socket. Great for location shooting.

Hook it up to a power generator. Honda 3000 come to mind! Flash won't last but you will have a blast shoot a few shots with it! Seriously it may be a weak mono light depending on what you want to do, and for just a few extra bucks you can get you into some really decent stuff with modeling lights built in and everything.

This will fit your flash from Quantum.
