This is one of only two original manufacturer USB chargers around. Kudos to Fujifilm for making a really nice USB-C charger that outperforms the aftermarket options for most other brands. It uses USB-C to charge batteries quite fast compared to most USB chargers. The closest equivalent if you don’t happen to have one of the two cameras that use the NP-W235 battery is Nitecore - they make good quality USB chargers for most cameras. If you do have the right camera, the Fujifilm charger is preferable - faster and a slightly better design.
The only problem with it is that it doesn’t come in the box with the camera. Even the $1700 X-T4 needs to come with a charger, and it is absolutely inexcusable for the $6000 GFX 100S not to.
