The power bank is not an accessory in Nigeria; it is a vital organ. You don't leave home without it. You have a small one for the bag, a big one for the office, and a solar one for emergencies. Your power bank has a power bank. It is the Nigerian's insurance policy against NEPA's unpredictability. The culture around it is specific. The "low battery" panic at 40%. The way you ask strangers, "Do you have a cord?" The power bank borrowing etiquette—return it with at least 50% charge, or you're a thief. The way friendships are tested when someone forgets to return your Anker. And the brands! The original Anker is premium. The no-name brands from Computer Village swell up after three months and threaten to explode. The ones with flashlights built in. The ones that charge your phone for ten minutes and then die. We've all been betrayed by a power bank at the worst possible moment. But the loyalty is real. A reliable power bank is a companion. It has seen you through blackouts, long bus rides, and all-night owambes. It is the silent hero of Nigerian connectivity. How many power banks do you currently own? And what's your worst "my power bank failed me" story?
