Powering a 633 soundbag via a USB powerbank

[Trouvier]

Hello everyone,

 

I was wondering if any one of you ever tried to power their SD633 recorder, HFs, etc. via a usb powerbank, since these are incredibely cheap compared to other power sources. I just stumbled upon these usb/hirose cables on Amazon and was wondering if this would work:

Any thoughts? about voltage, intensity? My electric knowledge is really nonexistent... 

In my bag is a SD 633, a Wisycom MCR42 and a Sonosax SX-M2D2. They all have hirose power in.

Thanks by advance for your help!

I would recommend buying even used professional NP1s before going this route. But yes, it would probably work.

Another option would be something like these Talentcells:

I've been using them for over a year with no issues. I'm not recommending them over a professional battery system, but I'd much rather use these than a USB step-up cable.

As long as the audio connection to your other USB bank powered devices (wireless receivers / transmitters) is balanced, this will probably work. Otherwise you will most likely get some dc/dc transforming and ground related noise.

At least find a power bank that operates at 12 volts. Otherwise you’ll be losing some efficiency to the boost converter. The RF/EMI noise could be a real issue.

Hey Trouvier,

 

In my experience Power Banks are not significantly cheaper than np-f 'L'  batteries (per Wh).  'L' batts fit directly to 6 / 8 series recorders and some have USB I/O. Very versatile.

The USB to Hirose cables are a good idea to have in back up or for a static rig but as secure as the Hirose end of the cable is, the USB end of the cable isn't and USB panel connectors get easily damaged. I use a HW battery mount in my bag to O/P 12 volts if needed from L series batteries and many bag devices will work from 7.2 anyway (eg MCR42). For c. cost of 1 Audioroot 96Wh battery you can buy nearly 6x 56Wh L series batteries - 3 times more power, 6 times more redundancy and you can double all those numbers as real world usage means you need at least 2 batteries packs (however good the brand is) as it would be 'suicide' otherwise. PBs are cheap but as your primary powering you are committing to a system totally reliant on a flakey connector. As a BU it's very good value though.
