Fujifilm NP-T125 batteries for GFX 50S and GFX 50R camera models. Connect the FX2 Pro to a quick charge (QC) power adapter and a single slot will achieve a max output of 800mA for fast, efficient charging. With a dual port design, the FX2 Pro simultaneously charges two batteries in only 3 hours so you can spend less time charging and more time snapping photos.
