Compatible Battery & Charger Kit

The Kastar IS360X3B kit supplies one 1800mAh lithium-ion battery and a triple USB charger built for the Insta360 X3 action camera. The battery stores 6.9 Wh at 3.85 V and matches the shorter 2.17" X .51" X 1.65" form factor required by the X3. The charger accepts 5 V 2.1 A input through either Micro USB or Type-C and powers all three channels simultaneously. LED indicators show red while charging and green when each cell reaches full charge.

Replaces Single-Bay Charging

The triple-channel charger replaces single-bay units that can only replenish one pack at a time, letting you restore three batteries in parallel from one 5 V source. This jump is worth it when you shoot extended 5.7K 360° sessions and need multiple spares ready without waiting for sequential cycles. The kit is not for owners of the Insta360 ONE X2, whose longer 2.36" X .55" X 1.57" cells will not fit the charger bays or the camera compartment.

USB Power Limits

The charger draws a maximum of 2.1 A at 5 V, so total output across the three channels is capped by that input budget. Each bay delivers up to 750 mA at 4.4 V, but simultaneous charging of three depleted packs will share the available current. A standard Micro USB cable is included, yet any 5 V source rated below 2.1 A will lengthen charge times proportionally.

Questions about this item

Will the charger fit the shorter 2.17" X .51" X 1.65" Insta360 X3 battery?

Yes, the charger is designed for the X3 battery measuring 2.17" X .51" X 1.65" and will not fit the longer ONE X2 battery.

How do I power the triple charger and what cable is included?

Connect the charger to a 5V 2.1A source using the included Micro USB cable or a separate Type-C cable; both ports accept 5V 2.1A input.

When should I replace the 1800mAh 3.85V Li-Ion battery?

Replace the battery when it no longer holds a full charge indicated by the green LED or when runtime drops noticeably below the 6.9 Wh rating.
