Why would it be too much power?
I assume it is a PD-capable charger, so Pinecil can request 20V and it is able to provide up to 3.25A for Pinecil - generally it should be a perfect fit.
Anyway, 45W charger should be too low to fully utilize Pinecil, as far as I know, its full power consumption is around 60W at 20V.
(For 60W power at 20V, it would need 60W/20V=3A of current.)
Also, basically a power supply can supply a voltage (like 20V) and up to a specified current (A).
So looking at this perspective, the higher current is better and it should work together with Pinecil if it can supply at least that amount of current (or above) what Pinecil need.
So, do not buy a 45W charger for Pinecil.
In this case, actual power (W) comes from voltage (V) multiplied by current (A) and current depends on the device connected and not on the power supply itself (if it is capable of delivering the needed value).
