We call them power banks not realizing it's akin to how we grew up calling (incorrectly) every shoe polish Kiwi. Power Bank is a registered trademark of the brand that helped popularize portable chargers. But they are just power banks, aren't they? Whatever. Now that you know what I am talking about, I'd like to know, which one do you use? I know you use one, which one is it? Also, how often do you use it?
[This is interesting because 1) Anker is keen on taking an active role in this market (Kenya and elsewhere in Africa) and 2) That Kileleshwa incident and 3) Portable chargers are the new flash drives. I mean, all events you go to these days, there are more chances that you'll be given a portable charger at the end of it all than there is that you'll have lunch on that day]
