What I like about the unit first is the portability, second is the wattage in such a small package 1800w with a surge of 2400w…I have a Bluetti AC200P but at 27.6 kilo’s that’s quite a chore to be moving around! I currently have the Bluetti on a cart that I can wheel around the house where needed. Anker has good products and with a 5 year warranty, it’s hard to beat👍
