The Core SWX NANO-C98 addresses the need for a "pro" style option of power for Canon cameras that accept the Canon BP-A style battery packs such as the Canon C200, C300 Mark II, or the new C500 Mark II.
The battery pack is equipped with a 4-stage LED gauge, a 5v USB, and a p-tap. The p-tap is a Smart Tap that serves as a standard p-tap, but it is also able to communicate SMBUS/smart battery data which is part of a future integration.
They can charge either via the p-tap, or with the OEM Canon chargers.
