Getting stuck without power is not ideal. The good news is there are now plenty of powerful emergency backup batteries you can use to keep your essential appliances going anywhere. Take the MONTEKSOLAR X1000 for instance: it is a 1000W portable solar power station with 10 output ports, including 1 USB-C, 2 QC 3.0, and 2 AC outlets.
The X1000 has a shock and water resistant design. It looks like a suitcase, so you can easily carry it around. It has enough power to keep your blender or coffee maker going for 1.7hours.
