Not long ago I showed off some portable 12V / 5V USB battery packs that were able to power a variety of camera accessories. These battery packs worked so great, I picked up a few more, and there's always one in my backpack (in case my cell phone runs low). YouTube member LucaFurgiuele runs a time test powering up the 352 LED Ring light at Full Power.
It's not often you'll use a light like this on full power the entire time, but these batteries were still able to push about 85 minutes of run time. Definitely not a bad deal for these versatile little packs. You can find some additional information about the batteries in my old post here. [Thanks Luca]

the batterypacks are very usefull for all different things but you might not want to open them. the build reflex the price. thin cables paper in the leftover spaces.
i closed them fast and consider not thinking about this again.

Post author@jane s - There is no voltage regulator on here to provide the necessary voltage to a Canon camera. This is not the battery to use. There are some solutions here for powering your camera: Powerbase Battery Pack for Canon DSLR

Can you use this battery to power the canon 5d with the use of a dummy canon accu connected to it? Still hesistating to do this ......afraid to blow up my camera.

Post author@Julien - From the battery I have, I need to have the switch 'ON' to make it charge. I thought my battery was bad after charging it all night, but it was because I didn't have the switched turned on. Once I turned the switch to the ON position and then charged it, they have all been working great.

hi Emm, i bought a battery 12v on ebay which look like this one you talk about but mine is blue. But i have 2 led light on my charger: one Red and one Green. when i turn on the battery the green light and the red light are on, and when i turn off my battery, the red light is on and the green is off. My question is that i don't know how if i must recharge my battery with the battery switch on or switch off.
i don't if you understood what i said, i'm from Belgium, i don't speak english very good.

I wish there was a similar battery for the 900 LED lights that would run at 15V.

Post author@getem - It's pretty bright, but does not dim down to 0%. At the lowest setting it's still pretty bright, so it's not super discreet and could be a distraction. Other than that it's a great light.

How does this light compare to the z96? Is it as bright and comparable ?
