I think the 55w fast charger can be used as a Bluetooth headset.
First, the current mobile phone fast charge head power is more and more large, such as the more common 33W, 55W, 65W, and even 120W. For example, the Xiaomi 10 Supreme Edition is equipped with a 120W fast charge head

It can be seen from the appearance that it is very large, the output voltage and current can reach a maximum of 20V, 6A
And our ordinary Bluetooth headset charging head power is about how much?

The maximum output voltage and current of the ordinary charging head are: 5V, 1A
There is a lot of difference between the two, and charging the Bluetooth headset directly will have uncertain damage factors
Of course, your Bluetooth headset may also support fast charging, to check their own Bluetooth headset charging head support power and input and output voltage and current parameters
If you can not find a charger around you, it is still recommended to buy a Bluetooth charger as soon as possible, do not mix, safety crime is important
No problem at all, the fast charge automatically determines the output voltage of the device being charged, and the Bluetooth headset will only be charged normally.
