Insta360 CINSBBMJ X4 Fast Charge Hub

The Insta360 CINSBBMJ Fast Charge Hub is a purpose-built three-bay battery charger for the Insta360 X4. For X4 shooters who work across a full day of coverage — events, outdoor expeditions, real estate walkthroughs, travel content — managing battery state is one of the primary logistics challenges of the camera. The hub solves it directly: all three bays charge simultaneously, and with a USB-C PD power source, each battery reaches 80% capacity in 26 minutes. That's a functional charge in the time it takes to debrief a shoot, eat a meal, or take a car ride between locations. The 80% threshold is also where most of the usable runtime lives — the final 20% charges more slowly in any lithium battery system, so the 26-minute figure represents genuinely usable power, not just a partial fill.

The hub's intelligent charging management system handles each bay independently, with individual overcharge protection per slot. This means you can drop partially discharged batteries in alongside empty ones without worrying about overcharging the ones that were fuller to begin with — each bay monitors and terminates its own charge cycle. At 3.84 oz and approximately the footprint of a large smartphone, the hub fits cleanly into a camera bag pouch alongside the X4 and doesn't demand its own dedicated compartment. The single USB-C PD input aligns with modern power adapter and power bank ecosystems, reducing charging infrastructure overhead when traveling. Note that the hub is X4-specific — it will not accept batteries from other Insta360 models, and batteries are not included.
