Core SWX

Core SWX LLC is an American maker of batteries, chargers and portable power systems for film, television and video production, based in Plainview, New York. The company was established in 2001 as Switronix, Inc., which gave its base as Westbury, New York, in 2011. It took the name Core SWX in September 2016, when it also moved into a larger facility in Plainview. Ross Kanarek is its founder and CEO.

Engineering, manufacturing, service and shipping are handled at the Plainview headquarters, and the company also runs a West Coast office in Torrance, California. Since 2021, IDX Company of Japan has distributed Core products in that country.

Switronix made NP, V-mount and 3-stud batteries, chargers and TorchLED on-camera lights, and introduced its first Hypercore battery in 2014. As Core SWX, the company introduced the Helix platform in 2019, on-board batteries that output both 14 V and 28 V; the compact NanoX line in 2023; and in 2024 the stackable SNAP batteries and Kodiak, a sodium-ion cinema battery.
