Rest assured, the YJS40 is compatible with all 12V lead-acid batteries, including those in your 2018 F350 6.7L diesel.

Versatility is key, and the YJS40 delivers. With a range of charging options, including USB (5V/2.4A), USB Quick Charge (5V/3A, 9V/2A, 12V/1.5A), Type-C (5V/3A), and a powerful DC (15V/10A) port, you can power a variety of devices, from tire inflators to car vacuums and refrigerators.

But the YJS40 is more than just a jump starter. Its integrated LED flashlight offers three modes - Flash, Strobe, and SOS - making it an indispensable tool for camping, outdoor adventures, or emergency situations.
