AXLY Dashboard Kit
Best Car Phone Chargers to Keep Your Dashboard App Powered
The short answer
The best car charger for running your phone as a dashboard is a USB-C Power Delivery (PD) charger of at least 30W per port — enough to keep the screen, GPS, and Bluetooth running as a dash cam and gauge display without the battery slowly draining.
Running AXLY screen-on as a dash cam or live digital dashboard uses real power — often more than a slow charger can replace, so the battery creeps down on long drives and track days. A USB-C PD charger sized to your phone keeps it topped off (and cooler) so it can record and gauge all day. This is the companion buy to your mount — together they complete the dashboard kit.

Your phone + AXLY = a free dash cam, digital dash & track timer
Mount your phone and AXLY turns it into three tools you'd otherwise buy separately: a dash cam that records the road with your speed burned in, a full-screen digital dashboard of live OBD2 gauges, and a drag-strip track timer for 0–60 and quarter-mile runs. It's all free in the app — you just add a mount and a charger.
Frequently asked questions
Do I need a charger to use my phone as a dash cam?
For short trips, no. For longer drives or track days, yes — recording video with the screen on and GPS active drains the battery faster than a slow charger can replace, so a 30W+ USB-C PD charger keeps the phone powered and cooler.
Why does my phone lose charge even while plugged in?
Older or low-wattage car chargers (5W–12W) can not keep up with a phone running the screen, camera, GPS, and Bluetooth at once. A USB-C Power Delivery charger rated 30W or higher adds charge instead of just slowing the drain.
What wattage car charger do I need for an iPhone running navigation and a dash cam?
At least 30W of USB-C Power Delivery per port comfortably powers a modern iPhone running AXLY in camera or drive mode. If you also charge a passenger device, choose a dual-port charger with 60W+ total.
