Ubiquitous internet and unlimited data plans got rid of any limitations for texting, calling, or browsing the internet. Speeds are fast and using all of your monthly gigabytes requires creative thinking. The gist is, you don't need to save data or call minutes for later use in the month.
The scarce resource today is battery. Yes, new phones go for one or two days with a full charge but that doesn't last too long as the duration of lithium-powered batteries slowly fades away with time.
That's what makes these power bricks useful—a portable charger that can recharge your phone a couple times removing the need to save battery. Without it, a drain battery is an opportunity to refrain from using the phone to save battery for something else later in the day, or simply to not use your phone after its battery dies.
The only resource you have left is time and—if you're not careful—your phone might drain it all as well.
