Review on 🔌 Vansoet 300W Power Inverter Car Adapter DC 12V to AC 110V with Dual 4.2A Smart USB Ports - Ideal Car Accessory Inverter for Laptops, Phones, and Cameras by Joshua Huan

I used these and some 12V deep cycle car batteries to build my own uninterruptible power supply for my 1000W PC and various other electronics (router, modem, switch, power distributor, etc.). Its capacity is more than what I currently need. , but I wanted to have a lot more space to expand if needed. And since my batteries can handle the load, I can always add another battery or two in the future if I need more time. Next time the electricity will be cut off because I have a storm. I will have my own computer and internet to entertain myself and I can even put a resistance heater on it to stay warm!
