Anker car chargers
The reference point for charging, properly specified, properly certified, sensibly priced.
Running maps on a bright screen with Bluetooth audio can outpace a 5W socket charger, so the battery falls during the drive. Anything doing sustained navigation wants USB-C Power Delivery not the cheap sockets bundled with older cars.
PD keeps up with navigation, unlike 5W sockets. Dual-port models cover a passenger. Cheap.
Some 12V sockets stay live and will drain the car battery. Loose sockets cause connection dropouts. Very cheap units generate radio interference.
Get at least 20W USB-C PD if you navigate. Check whether your car's socket is switched with the ignition, if not, unplug it, because a charger left in a live socket can flatten the battery over a week.
The reference point for charging, properly specified, properly certified, sensibly priced.
Broad, cheap and generally well-reviewed charging and car accessories.
Navigation with the screen at full brightness drains faster than a slow charger fills.
