Portable 12V / 5V USB Battery Pack Test w/ 352 LED Ring Light

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]

  1. 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.

    @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.

    @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 ?

    I mostly shoot Music Videos so IM generally no more than 5-10' max from My subject.

    Really interested in purchasing this
