In this video I put a bunch of popular wireless CarPlay adapters through something most people never test: heat. Wireless CarPlay is awesome when it works, but when an adapter runs hot, that’s when you start seeing random disconnects, lag, or it just flat-out stops responding. So I lined up a few options—Carluex Pro+ 2.0, Ottocast Cube, Ottocast Mini, and a cheap non-branded adapter—and did a side-by-side thermal comparison using a thermal imaging camera. The goal here is simple: find out which adapters stay cooler during real use, because temperature is a big part of long-term stability. I’m not just talking about a quick boot-up test—I’m looking at sustained usage where these things typically get stressed. If you’re shopping for a plug-and-play wireless CarPlay adapter and you’ve been worried about overheating, this heat comparison makes it easier to pick one that’s more likely to stay stable in the car day after day.
