2 Spigen onetap pro 3 cryomax chargers, 2 different charging speeds

Hellp

I have the Pixel 10 Pro XL. On that I have the Spigen Rugged Armor MagFit case which is "MagFit" compatible. After much research I found the OneTap Pro 3 Cryomax Stand which I use to charge my phone every night. Using the Ampere app, I see a nice flow of around 2,000 mA without any adjustments.

Fast forward a month or two I get the OneTap Pro 3 CryoMax Hook Car Mount thinking I would get close to the same result.

I find that through many trips in the car with Ampere running I top out at 900 mA.

I know it's not the charging adapter because that gives out 52w. I try it at home with a anker 67w charger and I get the same result.

I then go buy the Anker Prime MagSafe Car Mount Charger. It gives me at least 1500 mA according to the Ampere app.

Any suggestions?
