I cant stop laughing here , so its not only nigeria that experience power outage. Thats good to know. And neighours coming to your house to charge there gadget😀😁😂😂. I need to show my friends this, the only difference there is that every home has a smoky-lousy generator, you don't want to see or experience it, its not funny at all.
Ive checked the big o battery post. Its amazing, i cant beleive such a small thing could power a house. But you didnt tell us how many hours this 500watt thing can take to charge a phone, laptop and two energy saving bulb.
