You may have a 4 amp wart thaz only 5 volts. Acoarst I dont know what voltage the charger needs for optimum performance.
I do know that my new phone needs more voltage than the old one, but uses the same cable. The new phone will charge but slowly on a generic 5 volt wart.
To a charger, a battery appears as a resistor. Voltage is what pushes against resistance.
Amperage is how much current will flow limited by the voltage thaz applied vs the resistance of the device. Wattage is just a summary figure (volts x amps).

Actually, Fuji recommends a 45W “wall wart” charger to power the unit via a USB-C cable, so powering it with 20 watts is likely the reason it’s charging them sequentially rather than simultaneously, which it is spec’d to do. Shame on Fuji for not providing either the power supply or the cable at the price they charge for this charger. One of the very few bad things I’ve had to say about Fuji.
I have the Pro Cube 2, dual battery charger, and it works great. It has adapters for the XT-2 and XT-4 type batteries along with an adapter for rechargeable AA batteries.
Attached photo illustrates charging times based on battery type.

I'm using a 20w Apple wall wart. That should be adequate, shouldn't it?

That should solve the problem.
The Apple 20watt charger should be able to provide enough power to simultaneously charge the two batteries in a reasonable time.

No. See my post above that Fuji recommends a 45W power supply.
If you’re charging in the US the typical household voltage is 110-120 volts. The wattage capability of the charger is what governs the capability and efficiency of charging a specific battery/device.

It should switch over automatically. I have one, but I wound up getting a third party charger too.
[quote=Rab-Eye]I have the FujiFilm brand charger for the X-T4 and I’m using OEM batteries. It will only charge one battery. My understanding is that it should charge one battery at a time, not both at once, but once the first battery is charged, it should switch over to the second one. It is not doing that. Has anyone else experienced this problem?

Thanks all. I appreciate your input.

If you haven’t already sent it back, get a much larger 45W wall wart power supply and try that - you’re going to need it anyway. Surprised B&H doesn’t recommend one and the appropriate USB C charging cable. BTW, did the instruction manual or box specify the power supply to be used?
