It’s definitely worth paying more for the upgraded ESR Qi2 Cryoboost and worth buying a second one. It charges faster and the fan which keeps it from overheating seems to only use around 1.5W of power. The fan really works! It also stops charging when the phone is fully charged. The magnet strength is excellent and the charging is fast. I could not recommend using this more. I like how the car vent mount has added support. It works with the Google Pixel 8 Pro with Magsafe cases and should work with the Google Pixel 9 Pro with Magsafe case as well.

It holds my IPhone 15 tightly and charges it fast. Super easy to assemble.My only issue was that I didn’t have a car adapter for USB-C cable so I had to spend additional $10 to order one.

I got this strictly for the cooling fan and it has not disappointed. my phone actually feels colder after I charge it than when I put it on the charger. This is great for anyone that goes on longer trips and likes to have their phone in view for GPS but know the struggle of it overheating 30 minutes into the drive.

My son put this in the car when we first received and it works very well. It does pull down on the air conditioner vent when you place it there. My car is about 8 years old so the vents are not as tight as they used to be. It does have an adhesive that you can place it on the dash but I chose not to do that. It charges the phone very well thru the case. It works as well as the name brand product. The magnet seems to be strong enough not to let the phone slip off.
