A flat smartphone battery on a long car journey is frustrating, but choosing the wrong car charger can also waste your money. A high wattage on the packaging doesn’t automatically mean your phone will charge faster. Ports, cables and your car’s power supply can all limit performance.
Pay particular attention to these three common pitfalls:
Read on to find out which specifications matter and which models are suited to different needs.
Most cars have a 12V socket. Lorries, motorhomes and some commercial vehicles use 24V. So a 12V car charger won’t necessarily be suitable for every vehicle.
Models with a DC 12–24V input offer greater flexibility. Examples include various PAVAREAL and Baseus models in the range. Even so, check your vehicle’s manual and the product specifications before ordering.
Power is measured in watts. For a smartphone, 20W to 30W is often enough for a quick charge, while a tablet or laptop may need more power. A PD fast car charger uses USB Power Delivery via USB-C. Check whether your device supports this protocol.
It’s worth distinguishing between:
A USB-A charger can be a good choice for older cables and accessories. For recent iPhones, Samsung phones and laptops, a USB-C car charger with PD is often more practical. Check the cable, too: one with a low power rating can limit charging speed.
A multi-port car charger is handy for families or commuters who want to charge a phone, sat nav and tablet at the same time. Check whether you need USB-A, USB-C or a built-in cable.
A built-in or retractable cable saves space, but make sure it’s compatible with your device. According to Oxerbog’s product information, the included Type-C cable is designed for iPhone 15, 16 and 17 series and Android devices; it isn’t suitable for iPhone 14 or older models.
Choose a model with a secure fit and use the charger according to the instructions provided. Bear the following points in mind:
A CE or RoHS marking can provide useful information about documentation and compliance, but it doesn’t replace checking the product specifications and instructions for use.

It depends on the port, cable and charging standard. A USB-C car charger with USB Power Delivery may be suitable for many recent iPhones and Samsung phones, but always check the product specifications for both the charger and your cable.
Yes, if your laptop supports USB-C Power Delivery and the charger provides enough power. Check your laptop’s required wattage. A 20W charger is generally intended for smaller devices; some laptops need a higher output.
A plugged-in adapter may use a small amount of power, depending on the model and the car. Unplug the charger if your vehicle will be parked for an extended period, especially if the instructions recommend doing so.
