Camera accessory maker ZILR has released the NP-F970 Power Kit, which provides you with everything you need to keep L-series devices running, and then some. The kit includes an NP-F970 battery, a USB-C to USB-C cable, a USB-C to lightning cable, a 65W wall charger, and every AC adapter plug you'll need traveling abroad.
What's unique about the kit is the ZILR battery has a USB-C connection that allows you to power multiple devices at once. Say you're shooting with Z CAM, and by connecting a USB-C cable directly to the battery, you can also power a smartphone at the same time. Or if you have the ZILR battery powering an Atomos Ninja V, you can connect a smartphone to the battery for a secondary monitor. The battery is capable of charging your smartphone as well.
