Magsafe charging speed - Pixel 9 Pro XL

I'm currently using the Pixel 9 Pro XL with the official Mous case. I have an Anker Qi2 charger. However I'm at 42 percent and attached the charger and it says in the charger it will take 5 hours and 49 minutes to fully charge. My lock screen charge time says like 4-5 hours. Is this an "acceptable" charge speed? Is there a way to check it verify, or is this just what to expect from magsafe charging?
