Four 2040 mAh lithium-ion batteries and a foldable-plug AC charger for Fujifilm X-T4, X-T5, X-H2, X-H2S, X-S20, GFX 100S and GFX 50S II cameras
This pack contains four 7.2V 2040mAh lithium-ion cells and a matching AC wall charger. It is built for owners of the X-T4, X-T5, X-H2, X-H2S, X-S20, GFX 100S or GFX 50S II who need spare power for long sessions. The cells replace the NP-W235 and the charger replaces the BC-W235. It is not suited to the older GFX 100 or GFX 50S bodies.
The wall unit accepts 100 to 240V at 50 or 60Hz and delivers 8.4V at 600mA to each cell. A red LED shows charging and a green LED shows standby or full charge. The foldable flat pins keep the outline slim for travel bags. No active cooling is used, so operation stays silent and the casing remains only warm to the touch.
Each battery stores 14.7 Wh and fits the same slot as the original Fujifilm unit. The charger plugs directly into a mains socket without a separate cable, reducing clutter on location. Four cells give enough reserve for a full day of stills or video without swapping packs. The set adds no extra mounting hardware beyond the camera’s own battery door.

Other versions of this model
Same family, different memory, cooler or clock — compare before you commit.
Slide each battery into the camera until it clicks, then plug the charger into a 100–240 V AC outlet and insert a battery; the LED shows red while charging and green when full.
Lithium-ion cells lose capacity over time; expect to replace the pack when run-time drops noticeably, typically after several hundred charge cycles.
The charger outputs 8.4 V at 600 mA, so each 2040 mAh battery takes roughly three to four hours to reach full charge.
