^ This. Also, been really happy with the thermal performance on the ESR HaloLock MagSafe Car Charger with CryoBoost. Basically, if you want to avoid that thermal throttling mentioned above, active cooling is the only way. I've tested it and the fan keeps the 15 Pro temps stable even when running Waze and Spotify... no complaints. Quick tips for the best setup:

• Use a 30W PD 3.0 adapter, like the Anker 323 Car Charger 52.5W... it works well with the ESR unit
• Look for MFM certification to get the full 15W peak, otherwise you're gonna be stuck at 7.5W on most budget mounts The ESR unit stays under $50 usually. Very satisfied with the sustained wattage tbh.

I totally agree with the point about staying away from those cheap no-name chargers, honestly. If you're running GPS and music at the same time, your iPhone 15 Pro is basically a heater. I’ve noticed in my own testing that performance drops fast when the thermals aren't managed, and the phone just starts throttling the charging speed to protect itself. So basically, I'd suggest looking into:
- Stuff from ESR, they have some decent tech for keeping things cool during use
- Anything from Spigen because their magnets and build quality are usually top-tier
- Just make sure the mount has some kind of airflow or cooling feature built-in Idk the exact wattage benchmarks for every single one, but going with a brand that actually cares about heat management makes a huge difference in real-world use. Anyway, just something to keep in mind if you're doing long drives!

I've been using the Belkin MagSafe Car Vent Mount PRO (around $40!) with my 15 Pro and it's been fantastic! Rock solid hold, even on bumpy roads. Just be absolutely sure your vent can support the weight, and maybe have a pro install it if you're unsure about vent integrity. Safety first! Amazing for navigation!

Unfortunately, many budget MagSafe chargers disappoint. I had issues with overheating and slow charging with some generic brands. Instead of chasing cheap, consider a used but reputable brand like Anker on eBay. You might find a previous-gen model around $30 that performs better long-term. Just check its charging wattage.

Honestly, MagSafe in cars is finicky. Had issues with overheating on long drives. Anker's magnetic mount ($30) with a separate fast charger might be more reliable, and cheaper in the long run.

Beware cheap chargers! Had issues with overheating. Anker's safer, but test it first.

Instead of buying one, I'd suggest a DIY approach. I've had issues with pre-made MagSafe mounts. I bought a generic magnetic phone holder for $15 and a separate MagSafe charger, then combined them. Not as elegant as Belkin, but much more reliable based on my 2021 experiences.

From market scans, Anker's MagSafe car mounts show consistently positive reviews. Check Amazon; user satisfaction outweighs other brands in the sub-$50 range. No complaints so far.
