You can power your smartphones, laptops, fans, lights, refrigerators and more with specific outputs-100W USB-C, 12V/10A cigarette lighter, and 18W USB-A. Waking up electronics on a freezing day may be time-consuming. But with the Temperature Adaptive Function, B300S will automatically heat up to work actively and smoothly as usual.
