Kastar IS360X3B Pack for Insta360 X3

This pack includes two lithium-ion batteries and a triple USB charger built for the Insta360 X3 action camera. Each battery delivers 1800mAh at 3.85V, providing 6.9 Wh of capacity. The charger powers up to three batteries simultaneously using either Micro USB or Type-C input at 5V 2.1A. LED indicators show red while charging and green when full or on standby.

Suits X3 owners needing extra power.

The batteries match the X3 dimensions of 2.17" x 0.51" x 1.65", so they fit the camera body and the supplied charger. Owners of the Insta360 ONE X2 must look elsewhere because that model uses longer batteries measuring 2.36" x 0.55" x 1.57". The pack is aimed at creators who want to keep shooting while spare cells recharge.

Charger input and output set the recharge speed

The charger accepts 5V 2.1A through Micro USB or Type-C and delivers 4.4V 750mA to each of its three channels. This fixed output determines how quickly depleted batteries return to full capacity. A Micro USB cable is included in the box.

Questions about this item

How many charge cycles do the 1800mAh Li-Ion batteries typically last before capacity drops?

Lithium-ion cells of this chemistry generally retain usable capacity for several hundred full cycles; exact cycle life varies with temperature and depth of discharge.

What limits continuous charging when all three bays are used at 750mA each?

The charger draws 5V 2.1A total, so simultaneous triple-bay charging at 4.4V 750mA per bay is within the input budget.

Does the charger get hot or noisy during extended multi-bay charging sessions?

No fan is present; the unit relies on passive cooling, so it runs silently and warm to the touch under full load.
