Varavon B-12V A7S overview

  • 1Description

This is a compact and sleek, external Battery Package, from Varavon, for the Sony a7S, a7S II, and a7R II cameras. It connects to the camera via an included dummy battery, and can be secured to your camera rig either by touch-fasteners or the Varavon Battery Clamp, both sold separately.

This is a dual-voltage battery; via a selector at the top, you can choose between 7.5V and 12V of output – the latter for compatibility with select Varavon devices. Overall between the two output voltages, it's compatible with the camera, and the Varavon Timeroid, Motoroid, and Birdycam, and it can be used with the camera and Timeroid at the same time.

At 7.5V, the battery delivers 10,400 mAh of capacity, and, at 12V output, you get 5200 mAh. Remaining battery life can continually be checked at the press of a button on the top.

    Varavon B-12V A7S reviews

    a7S Battery Package is rated 3.3 out of 5 by 7.
    Rated 5 out of 5 by from Great solution for A7SII after slight modification It works ok out of the box but when you touch or turn the output cable it often cuts power to the camera. Search youtube for (Issue with Varavon External Battery Pack Connector - Sony A7RII) and there is a guy named Ian that shows you a simple modification to the tip of the cable that allows a better connection and eliminates power drop outs. It works great and makes this a solid power solution. I purchased the Varavon bracket as well and it works great for mounting this to a 15mm rail.

    Rated 4 out of 5 by from For Sony Cameras - almost perfect This battery is for Sony cameras that use the NP-FW50 battery. The unit is built in Asia, it does not include an American 2-prong plug that goes into an electrical outlet. Fortunately, I have one. It would be nice to cater to the country that the buyer is using it in. I tested burned that battery. Remarkably it lasted for 15 hours! That is amazing. That equates to 15,300 mAH.The unit was always cool. It did not overheat. No apparent problems. The camera low battery light came on after a couple of hours, but that was an incorrect idiot light from the camera. As I said, I had full functionality for 15 hours! In conclusion, it is almost perfect. If only it had an American plug to charge the unit with.

    Rated 1 out of 5 by from Not ready for prime time Nice idea in theory; an external battery to extend dismal battery life of the Sony A7 family when shooting video. However, the unit I received was not able to provide this function; the A7Rii wouldn't turn on at all when plugged into this unit. With the A7S and A7, the cameras shut off automatically after half an hour of shooting with the unit still indicating 40% power left on its LEDs. On top of this fatal defect, the cable system is awkward with an extra, unnecessary connection between the battery unit and the camera adapter - another thing to get pulled or misplaced under the pressure of a shoot. Plus the cable is thick thermoplastic, which gets stiff in cold weather and doesn't fit very well through the little opening on the camera battery door. All in all, another product rushed to market without sufficient testing and/or quality control. Definitely buyer beware!

    Rated 1 out of 5 by from Piece of junk! Mine was dead on arrival. Never worked from Day 1. Emailed company, they never even bothered to answer. Avoid this product like the plague.

    Rated 3 out of 5 by from Could be improved As mentioned in an earlier review, it would be nice if the charger had a US standard Wall plug. My unit did come with an adapter. Also experienced the low battery indicator on the camera. But it seemed to work fine. What also like to see the dummy battery have a cord that plugs directly into the Veravon unit itself without an additional Cable adapter. I don't need 6 feet of cable between the battery and the camera.

    Rated 5 out of 5 by from update to Sony camera - external battery after further looking in the shipping package, an American 2-prong adapter was included for charging the battery. I have hence given it a 5-star rating. Perfect product.
