Better Battery Life For Sony Mirrorless | The Sony Multi-Battery Adapter Kit

By Wendell Weithers on April 20th 2017

One of the clear signals sent by Sony’s announcement of the a9 is that they are not only paying attention to, but, more importantly, finding ways to address the complaints about their products. The list of issues could be longer but, here are a few complaints users have voiced: inefficient menus, ergonomics, lack of lenses, and battery life. The battery life issues stem from Sony’s commitment to a smaller form factor for their bodies. And while the A9’s larger battery is a step in the right direction, it still isn’t on the level with comparable DSLRs from Canon or Nikon. With the Sony Multi-Battery Adapter Kit, they are taking up the challenge of rectifying their battery power woes; let’s what they’re offering.


  • For NP-FZ1000 & NP-FW50 Type Cameras
  • Extends Shooting Time
  • Holds up to Four NP-FZ100 Battery Packs
  • Rapidly Charge Batteries
  • Charges Four Batteries in 480 Minutes
  • Converts to Compact Two-Battery Pack
  • Two USB Ports for Charging Devices
  • Three-Level LED Indicator Light
  • Six 1/4″-20 Mounting Sockets
  • Includes Two NP-FZ100 Battery Packs

The beauty of this accessory is that is not only addresses the power limitations of Sony’s new a9 and any future cameras, but it is also compatible with any Sony camera that uses the NP-FW50 battery. This means you have a 1st-party power solution for your a5xxx, a6xxx, and a7xx series cameras. The catch is that, at $400, it is not a cheap solution, but this isn’t foreign territory for video shooters who are accustomed building out rigs around their camera’s shortcomings.

One nice feature to call attention to is that you can choose whether to power your camera or charge your battery when connected to DC power.

This accessory is an encouraging and revealing move from Sony. They care about your battery life complaints, but the issue probably won’t be solved in camera any time soon.  Still, its not a half measure deployed to placate the Sony faithful, but a well thought out attempt to  serve them.

    Can a third party please start producing cheaper a9 batteries! At £75 each, they too expensive (and too easy to lose).

    $400 for a battery charger is ridiculous.

    Lovely, but wouldn’t a chunkier A9 grip simultaneously:

    1) …allow for larger capacity batteries

    2) …better wield those ‘cuz-physics-said-so’ large and heavy f/1.4 primes and f/2.8 zooms

    3) …provide more room for additional knobs / buttons / LCD on the top?

    A multi-charger like this is probably still a must for a mirrorless system, don’t get me wrong, but I think Sony laid an egg on keeping things tiny with their flagship pro setup.

      They do seem very committed to the smaller size. I thought there was ample room between the a7xx bodies and CaNikon bodies to allow for a more substantial increase, but they are sticking to their guns.
