Quick answer
Choose the Belkin Dual Car Charger 42W if you need USB-C fast charging or want to charge a tablet alongside a phone. Choose the Dual USB-A Car Charger 24W with Lightning cable if you have two USB-A devices and want a cable included for a simple, lower-cost setup.
Why the port mix matters more than the wattage number
The 42W charger splits its output into a 30W USB-C port with PD PPS support and a 12W USB-A port. That means one device can charge quickly over USB-C while a second device charges at a standard speed over USB-A. The 24W charger gives you two USB-A ports sharing 24W total, so both devices charge at a more modest rate and neither gets USB-C Power Delivery.
If your phone or tablet uses USB-C and you want fast charging, the 42W model is the practical pick. If both devices are older USB-A phones or accessories, the 24W model covers the job without paying for a USB-C port you will not use.
The cable question: included versus bring your own
The 24W charger includes a 1-meter USB-A to Lightning cable, so an iPhone with a Lightning port can be connected right out of the box. The 42W charger does not list a cable in the supplied specifications, so you will need to supply your own USB-C cable for the 30W port and a USB-A cable for the 12W port. That is not a flaw, but it is a cost and planning difference worth counting before you choose.
When the lower-wattage charger is the smarter buy
The 24W charger is smaller in total output and uses two USB-A ports, which suits two phones that charge overnight on a commute or a mix of a phone and a basic accessory. It also costs less at catalog price, and the included Lightning cable removes one extra purchase. The trade-off is slower charging and no USB-C PD PPS support, so a USB-C tablet or a phone that relies on PD fast charging will not get its fastest possible rate.
Trade-offs to weigh before you buy
- Speed versus simplicity: The 42W charger gives you a 30W USB-C PD PPS port for fast charging, but you must supply the USB-C cable. The 24W charger is slower but includes a Lightning cable and needs no extra parts for a Lightning iPhone. Check which cable you already own before comparing prices.
- One fast port versus two shared ports: The 42W model dedicates 30W to USB-C and 12W to USB-A. The 24W model shares 24W across two USB-A ports, so charging two devices at once splits the power rather than giving one device a fast lane. If two devices must charge quickly at the same time, neither charger is ideal; prioritize the device that needs the most power.
- Device port check: Use the 42W charger if at least one device charges over USB-C and benefits from PD PPS. Use the 24W charger if both devices use USB-A cables and you want the included Lightning cable for an iPhone. Match the charger to the ports on your devices, not to the total wattage alone.
