550va is the inverter's power design, means nothing on run time.
home use typically only run couple mins on full power.
assuming 550W for 1min, for typical 12V, you are looking at 50A current
out of the battery, so the capacity needed is 0.9AH per min.
typical UPS is 3~9 AH, so you get 4 to 10min at max.
for modems/routers/phones etc, 50W should be enough.
you get near 1hr out of it.
if you get the 24V backup version, it is easy to hook car battery on it.
it will last for days.

: 550va才30min?是不是稍微有点短了...个人感觉起码2-3个小时才够实用

3-9AH也太小了吧。。。普通五号充电电池现在不都有2000+mAh的了?这不这么一个大
东西储电能力就相当于几节电池啊

50W大概能坚持1小时
