For your DJI Mini 4K drone (which is probably a DJI Mini 3 Pro, as there is no official "Mini 4K"), there are several accessories that are compatible: - Battery: The DJI Mini 3 Pro uses specific batteries that are not compatible with other models such as the Mini 2 SE or Mini 2. A suitable charger is the Two-Way Charging Hub, which can charge three batteries simultaneously. - Propellers: The propellers for the DJI Mini 3 Pro are specific to this model and should not be interchanged with other models. - Bag: A waterproof hard case is useful for transporting the drone safely. DJI does not offer its own hard case, but there are many third-party supplier options. Make sure you buy accessories specifically designed for the DJI Mini 3 Pro to avoid compatibility issues.

The propellers of the Mini 3 Pro and Mini 4 Pro are compatible.
