@movement19 The laptop itself is a DC device and it's battery is DC. The solar panels themselves are DC devices. The Li-ion battery pack inside the 'solar generator' is a 14.8 Volt DC 16AH battery that powers the inverter to make AC. Even pure sine wave inverters like that one are not as efficient as if you just went DC from the battery pack from the solar generator's 12 Volt utility port which is also called the cigarrete port or 'DC Out' in the image I have included. Making AC power to power a DC device (the laptop in this case) when you already have DC power available is inefficient and an unecessary step and wastes your battery pack's stored power and/or the power you are generating to charge the battery pack with the solar panel.
AC
@movement19 a DC to DC travel charger would be much more efficient for charging the laptop. I like the experiment.
if the generator is ac and the laptop is ac why would i use any convertors?
