Insta360 X4 Fast Charge 3-Bay Battery Hub

Three Insta360 X4 batteries charged at once, ready for the next shoot

A dedicated three-bay charging hub for the Insta360 X4 360-camera battery. Drop three batteries in, connect one USB-C cable, and every cell tops up in parallel so you spend less time waiting and more time filming.

This is the Insta360 X4 Fast Charge 3-Bay Battery Hub (model CINSBBMJ), a compact charging dock made by Insta360 for the X4 2290mAh battery.

It holds three batteries side by side and charges all of them at the same time from a single USB Type-C input, using USB Power Delivery so the hub can draw the current it needs from a compliant PD adapter or power bank.

Paired with a 12V/3A adapter, each battery reaches around 80 percent in about 26 minutes and full in about 43 minutes, which is fast enough to turn a spent set of batteries around inside a single break on a shoot.

Inside, an intelligent charging circuit shares current across the three bays and gives each slot its own overcharge protection, so a full or faulty cell does not affect the others.

A per-bay LED shows the status of each slot, so you can see at a glance which batteries are still charging and which are ready to swap back into the camera.

The hub measures 75 x 62 x 34mm and weighs only 109 grams, so it drops into a camera bag without taking up real space.

Remember this is a charger hub only: the X4 camera and the batteries are not included unless you add them to your rental, and you supply a USB-C PD wall adapter to power it.
