12V DC Battery with 5V USB Port

A while back I posted about some available 12V DC batteries you can use from Ryobi. They've been working great and many people have adapted them on Timelapse rigs and motion controlled sliders. Here's another option. Now I'm fairly weary about posting no name battery packs, so i've been testing these for a few weeks now before I decide if they are any good.

I originally purchased two of these CCTV Battery packs because of the 5V USB option. These little batteries hold quite a charge and i'm able to fully bring my dead cell phone or iPad back to life (charging through USB) several times over before needing to recharge the Pack again. These USB chargers are the most handy thing when you can't be tied to an outlet (like when traveling).

They also come with a double sided barrel connector to power up 12V DC items, and those have been coming in quite handy as well. The connector fits most standard Camera accessories, but you can always get additional ones to power up other accessories that will run on 12V or 5V DC. [Note] At Radio Shack it's 'AdaptaPlug Size N', elsewhere the common plug is 5.5mm OD and 2.5mm ID Male Plug. The battery uses negative from the outside and sends positive from the inside. Just make sure you have the inside as Positive and the Outside as Negative when making your DIY plug. You can see what that looks like, and find some easy DIY tips here: 5.5mm Male DC Plug Tips

I've been able to power up the Z96 LED light, the 312 LED Video lights, the SmallHD DP6 LCD monitor (and other monitors), the 352 LED Ring Light, and the list goes on and on. So many times you'll catch one of your accessories out of AA's or Sony's, and this backup battery solves them all. [Update] The Zoom H1 can be powered via USB, just figured that out when my AA battery was dying out on location.

I haven't done any real battery testing to see if the 3800mah /12V DC specs they list on the website is actual, but they do hold a charge and power up all my accessories for quite some time. Fairly light weight so all it takes is a bit of Velcro to hang it on the back of your Lilliput LCD monitors, or Portable LED lights that can accept DC in (like the Z96 or 312 LEDs). Unfortunately my 900 LED lights require 14V DC to be at it's 'Brightest' setting, but these little 12V DC batteries will power them up as well. Definitely not a bad price, and I have a few more on order. Trust me, i'm still putting them through the ringer. You can find them (click here).

[Update] Some of these items might not ship with the correct barrel adapter which is 5.5mm OD and 2.5mm ID. A comment left by Luca has links to some adapter cables. [Thanks Luca]

I found these DC cables that should fit quite nicely. The problem is, they're quite short:

So here is an extension cable:

    @Fabio - Yes, you can use this with the BMPCC also. You just need to make your own cable, and find a clever way to mount it.

  3. Hello.

    @IntrygueGraphics - The adapter may plug in, but the battery you use will determine your run time. The 12V/5V USB battery may not have a very long run time.

  5. @Emm OH WOW AWESOME Thanks EMM!!!!

    so I should be able to use it to power these:

    I plan on getting these tomorrow but i will hold off until you reply. I cant afford the Tekkeon batteries you recommend. I didnt think you would actually reply lol.
    I have bout all of my equipment thanks to this site. from my t2i camera to my jib.

    Can anyone please confirm whether this works for PS Vita? Also, can you play while charging? Thanks in advance - great site!!

    @Lee - The GoPro can be powered via USB, and this can continue to power it. If you want to charge the battery, I think the GoPro has to be turned off.

    Hi Emm, it's me again. Just wondering- do these power up the Gopro or just charge the Gopro battery in camera?

    Wondering if I should get these instead of spare Gopro batteries..

    I have one of this nice battery. So, can the H4n can be powered by it for record ? If it's the case, where can I find the Usb cable ? Thanks

  10. Zoom H4N can be powered by usb, but only for usb functions. (card reading, usb audio I/F), not using as a recorder. I just bought a usb to 4.0mm cable on ebay and hopes that works

    @dave patterson - All USB is 5V, but not all have the same milliamp output (how strong the battery is). Also not all units can be powered via USB. The Zoom devices can, but not too sure about the Tascam DR-40.

  12. Q: Do all USB devices run on 5V? Any special concerns to look for when purchasing a USB battery supply?

    I have a Tascam DR-40 audio recorder, and want to power it with an external power supply, as phantom power for condenser mics puts a strain on battery life. Any insight on this would be greatly appreciated.

    I have a couple of these 5v/12v 5800 mAh batteries, they work great as I velcro them to the back of the Z96 lights, however I just bought another one that is only 12 volt and 9800mAh (linked above in Frank's post) but it's almost twice the size and boy is it far heavyier! (440 grams vs only 147 grams with the 5v/12v) We'll see if it doubles the runtime... won't be sticking this brick to the back of the light with means alternative placement and longer cables (excellent for a shoulder rig counterweight though)

  14. Hi - I saw you using this on your iPad. I get an error "Charging is not supported with this accessory" when I try it on my iPad 1 or iPhone4. Both are running iOS5 - have you tried it with your updated iPad?
    Thanks - Martin

    Hi Emm!

    Can you confirm/test if this battery can power both a 12V device and 5V device at the same time?

    I asked the ebay seller "dib-bid" and was told that it cannot.

    If you're using a light hooked upto the 12V watch out for a voltage drop / brightness drop, when plugging something into the USB.

  16. Waveform

    Can anyone confirm if it can charge both a 12V device and a 5V Usb Device at the same time?

    I asked the ebay seller "Dib-Store", who said it cannot.

    Would really appreciate if someone could confirm this

    Hey guys...

    I am going on an extended trip in november and i need to be able to recharge dslr batteries whilst on the road. The DC output seems great, has anyone used one of these batteries to recharge camera batteries?

    Another problem i face is i want to shoot on the road with the new sony a77. Does anyone know if the sony a77 batteries are the same shape/size as any other older sony camera batteries? that way i could get an older camera adapteor and apply it to the a77.

    really stuck here, the canon 7d has an awesome setup to charge on the road via a battery via "powergorilla" but they have no specific adapter for the sony yet

    any halp would be greatly appreciated

    @Tim C - What were you using them for? I have 4 of them and i've been using them regularly. In fact i'm building my Glidecam for this weekend to power my SmallHD DP4 as a monitor.

  23. Hey Emm, Long time (relatively speaking) reader, first comment. I bought two of these and they both crapped out. I contacted them after the first one died and they refunded my money. We'll see on the second one.

    Great while they lasted!\TC

    Nice article....my problem is I don't know if this will work to power the DC in on a Nikon D300 camera as they use a strange adapter end coming out of their AC to DC power adapter, the plug end of which can be seen here:
