Mine are all over 1200 (whatever they measure them in) and I've run my dual monitors, and two computers off them for a few minutes after power went out. My newest is digital and starts at like 300 minutes then when the power fully drains and it draws 100% from it it goes down to 15 or 11 depending what monitor I have. Either way, I think you are right "not the best" but it could work with some string lights, or LED christmas tree lights
