Here my two cents regarding generators. FYI, I ended buying a small capacity (rated at 1000W, 1500W max) - enoug to power lights, TV, maybe 2 electric fans, and a desktop computer (maybe more small appliance pwede pa).

So bakit nga ba maliit lang binili ko?

Naiisp ko kasi kung saglit lang brownout, yung basic needs lang kelangan ko i-power up. Fans, lights, maybe TV, and computer kung may deadline or kelangan tapusing report. No need for aircon and refrigerator kasi saglit lang naman ang brownout.

Eh paano kung matagalang ang brownout (say 1 or 2 weeks)? Magandang tanong. I still won't plug-in the aircon and ref and other appliance na malakas ang consumo. Bakit? Malakas na ang gastos niyan sa gasolina. So alisin lahat ng laman sa ref at bumili na lang ng for one day.
