Power banks have managed to hold their own in the wake of competition from better batteries as well as smartphones that double up as chargers, thanks to reverse charging. Well, as one would expect, not every smartphone boasts this capability, even though the majority now bears massive batteries that hold the juice for longer. But this doesn’t cancel out the need for a power bank. They remain a lifesaver for professionals and students.  

While power banks are critical for people on the move, it is of some value for people staying indoors. Manufacturers are bundling their proprietary fast-charging bricks with the smartphones but barriers like frequent electricity cuts continue to compel people to look for backups that could power up their devices in absence of a wall outlet. This is where a power bank cues in.
