Core SWX, a privately owned company headquartered in the US, was founded in 2001 and employs approximately 20 individuals. It provides charging solutions for the broadcast, digital cinema, and professional video industries, focusing on video production. The company designs and manufactures innovative battery-based solutions for mobile powering applications spanning various industries.
On March 27, 2026, Core SWX released an informative video explaining why camera batteries might indicate a charge but still cause lights or cameras to power down, detailing the underlying principles of power delivery. Earlier on March 27, Core SWX addressed the challenge of limited battery life for iPhone filmmakers, particularly when recording in power-intensive formats like 4K HDR or high frame rates, which can quickly drain phone batteries. This followed the company's March 18 guidance on extending battery runtime and setting up rigs for the Sony FX3, a compact full-frame cinema camera often challenged by battery life during productions. Previously, on February 12, Core SWX partnered with Beastgrip to showcase how to integrate secure locking DC power into iPhone filmmaking rigs, providing stable voltage and preserving iPhone battery life with a system designed to prevent accidental disconnects. This collaboration built on a February 10 video where Core SWX and Beastgrip demonstrated the integration of the Blackmagic Camera ProDock into various iPhone-based setups, emphasizing the secure and uninterrupted operation achieved by using locking DC power from Core SWX batteries.
