Questions about this item

Does the triple charger generate noticeable heat when charging three 1800mAh batteries at 750mA each?

The charger outputs 4.4V at 750mA per channel, a modest current that typically keeps temperatures low during simultaneous charging of all three packs.

Which cables and power sources do I need to run the charger?

The unit accepts a Micro-USB or USB-C cable connected to any 5V 2.1A USB power adapter or port; a Micro-USB cable is included in the box.

Will these 2.17" × 0.51" × 1.65" packs fit the older Insta360 ONE X2 that takes 2.36" × 0.55" × 1.57" cells?

No — the X3 batteries are shorter and thinner, so they are physically incompatible with the ONE X2 battery compartment.
