[1] Works great. Powers my camera via 4 pin xlr.There were cheaper power supplies available off of @ but went w/ this Switronix one due to the brand name and the fact that it was powering such an expensive piece of equipment. Although the power supply comes in a branded Switronix box, the power supply itself is not labeled Switronix, which made me think that Switronix perhaps outsources this supply and it maybe the same ones that are on @ for 35USD. But better safe than sorry. I am happy with it.

[1] I was upset that my YAGH for the GH4 didn't come with a power supply. This made it work like a charm.

[1] Bought this product to replace a broken power pack for a teleprompter monitor. It's solid, works fine & looks very similar to the original but is actually easier to 'click' in/out of the connection than the previous one I had. It's pricier than I'd hoped but nothing bad to report - very satisfied.

[1] I purchased the LUMIX GH-4 with the YAGH interface last fall, and was baffled it came with NO POWER SUPPLY. Not only was it not included, I could find nothing about it on Panasonic's site or in the packaging that it came in. I was very frustrated until I found this gem. Works just as it should. Still scratching my head about why Panasonic didn't include this essential item, but Switronix came to the rescue.

[1] Bought to replace my SmallHD 1303 power supply after it had broken. No complaints thus far, hasn't had any problems.

[1] This is a XLR 4wire power supply. It works great for certain soft box lights, and some BlackMagic Design cameras. It works well, as advertised.

[1] Been using this unit 24/7 since it arrived and haven't had an issue yet. Using to power a Panasonic 360 cam.

[1] This adapter replaces the adapter for the Sony PMW-F3. It is substantially less than the genuine model and provides the same power supply. Recommended.

[1] Relatively small and easy to transport. Label on the item reads MODEL 1206 though the B&H listing and the item's box read SPU-4. Great for worldwide travel. Powers my Panasonic GH4 and YAGH interface just fine. Very useful product at a good price.
