Quick doubt: I want to keep my TopCarPlay plugged in but also charge another device. Can I use a USB hub with it? Not sure if that messes with the wireless connection. Anyone tried?

Hubs can mess with it, mine kept dropping.

Mine’s been running through a cheap powered hub for about four months now and the wireless side hasn’t skipped a beat. I keep the adapter tucked in the console and charge my wife’s phone off the same hub on road trips. Zero dropouts so far, so I’d say go for it.

I ran mine through a little hub for a while and CarPlay still paired fine, but charging got noticeably slower for whatever was on the other port. Not a dealbreaker, just something to expect. If the hub is decent it should at least be usable.

I’ve had mine on a hub for a while and honestly the wireless part never cared. What got me was the car side. My head unit would act like the adapter vanished for a second when I plugged something into the other port, screen would blink and then come back. Didn’t drop the phone pairing, just a little hiccup on startup.

I ended up moving the hub to the console outlet instead of the dash one, mostly because of cable clutter, and that blink basically stopped. No idea if it was the port or just dumb luck.

The other thing is heat. With two things drawing off the same spot the adapter got noticeably warmer to the touch. Still worked, but I noticed it. So it’s less about the wireless connection and more about how your car handles the power split. Some cars are fine, some get moody.

No hub here, just a straight connection.

I use a hub with mine and it’s been totally fine, wireless still connects every time I get in the car. The only thing I noticed is the adapter sometimes takes a couple extra seconds to boot up compared to plugging it straight in. Other than that, no complaints at all.

A hub has worked fine for me. My TopCarPlay stays connected in the console and I charge a second phone off the same hub on road trips. No dropouts so far.

A hub is fine for keeping it powered, but don’t expect the second port to charge anything fast. Mine handles both, just slowly.

I tried a hub for a couple weeks and ended up going back to plugging the adapter straight into the car port. For me the issue wasn’t the wireless side at all, it paired and reconnected the same as always. What bugged me was the boot time in the mornings. With the hub in the chain, the adapter seemed to take a bit longer to wake up, sometimes I’d already be backing out of the driveway before CarPlay showed up on the screen. Without the hub it’s basically instant. So it’s not that a hub breaks anything, it just adds one more thing in the middle that has to sort itself out. If you mostly want to top up a second device on longer drives it’s probably fine, but for daily quick trips I’d rather keep the connection as direct as possible. Just my two cents from messing around with it.

I’d skip the hub. Mine worked fine for a couple weeks, then the adapter started dropping the wireless link whenever I plugged something else into the same hub. Straight into the car port has been solid ever since.

Wireless connection shouldn’t be affected by a hub since that part runs over Bluetooth and Wi-Fi anyway. Mine stayed paired fine even with stuff plugged into the hub, it was the charging side that felt sluggish to me.

I ran a hub for about a month and pulled it out. Not because of the wireless link, that part was fine. The adapter just wouldn’t come back after the car sat overnight when the second port had something drawing off it. Unplug the extra device and it started right up again. So it’s not the connection itself, it’s the power. Cheap hubs split whatever the port gives you and the adapter gets fussy about it. If you actually need to charge something else, use the 12V socket with a separate charger and leave the CarPlay port alone. That’s what I do now and I haven’t had a single dropout since.
