Add dual L-Series battery support for your Sony a7 series camera with this Dual L-Series Power Adapter from IndiPRO Tools. The adapter features an NP-FW50 dummy battery on an integrated cable, and also offers an unregulated 14.4V, 2.5mm DC output on the side for simultaneously powering a second device. Both L-Series batteries must be used at the same time and will extend camera runtime by up to several hours, depending on the models you use.

The adapter has a 1/4"-20 threaded mounting hole on the rear for attachment to cages, rigs, and other supports; and the cable is 20" long, so you can mount the adapter on the back of your rig for counterbalance. The dummy battery is compatible with the Sony a7 I/II, a7S I/II, and a7R I/II cameras, and inserts in place of the existing camera battery. A 4-LED gauge on the front will indicate the approximate runtime remaining.

Related Questions and Answers

Q: 1. How does this mount to the camera - or will you need a cage?

A: You could use a hot shoe to 1/4 adapter to mount this on top of the camera. The Vello Multi-Function Ball Head with Removable Top & Bottom Shoe Mounts would be one example. However, this is fairly large and might be rather awkward. If you do not want a cage, then get a mini baseplate with 15mm rods such as the IndiPRO Tools DSLR Baseplate with 9 15mm Rods. Then with IndiPRO Tools Dual 15mm Rod Clamp with 1/4 -20 for Power Pod, you can mount the Universal Power Pod to the rods.

Q: 2. how long is the cable from the pod to the fake battery?

A: The cable is 20 inches long.

Q: 3. Is this safe to use with the Sony ZV-1? I thought that the maximum safe input to the ZV-1 is 5V. But the output of this dummy battery and converter is 7.4V.

A: The IndyPro Tools AC Power Supply with NP-BX1-Type Dummy Battery is fully compatible with the Sony ZV-1.

Q: 4. How many devices can this connector power at a time?

A: The IndiPRO Tools V-Mount Plate with Sony NP-FW50 Dummy Battery has a connector that goes into Sony cameras like the a7 that take the dummy battery connection. The plate has also a d-tap for one other device. If you need to power more devices, you can use these splitters. Just keep in consideration, the more devices you power, the shorter the time the battery can power the camera.

Q: 5. Is the voltage regulator in this system the same as the one in the 30 long regulated IndiPRO Tools MINI-Tap?

A: Yes, it uses same regulation boards.

Q: 6. If only one DC out is used for the dummy battery into the camera, can all 4 batteries' power be directed to the one DC out? Or can only two batteries go to one DC out?

A: As it seems all 4 batteries goes to both the DC out. I have tried with 1, 2, 3 or 4 batteries when it was connected to my Sony camera, I can swap any of them without loosing power so all 4 must go to both the DC out at the same time.

Q: 7. Will this charge and power a Sony as7 ii with an original dji ronin? through dtap?

A: You can power (but not charge) an a7 camera with this cable and a D-Tap power source.

Q: 8. What voltage are the two DC out sockets? i.e can I power a SmallHD DP4 monitor as well as the camera?

A: Yes you can power both units. Each output is 7.4 volts, you would need buy this cable to power the SmallHD DP4B&H # IN81PPC MFR # 81PPC

Q: 9. I already have this that I purchased years ago. I wonder if I attach dc input adapter (from ninja v) on to this. Does this convert any voltage power to 7.2v for sony a series camera?

A: The IndiPRO Tools Sony L-Series Battery Adapter Plate to Sony NP-FW50 Dummy Battery is designed only for use as a power source for cameras that use the NP-FW50 battery. Any other use would be at your own risk.

Q: 10. Is that a p-tap or a d-tap?

A: D-tap and P-tap are two names for the same thing. D-tap is generic and P-tap is Anton Bauer's trademark name. There is no difference in the connection or performance.
