How Does A Portable Power Bank Work?

A power bank is essentially an external battery in a sealed case. Powerbanks come with a USB cable; you connect it to a power source such as a laptop to charge the powerbank. Some charge via flip out blades for plugging into the wall. In either case, you carry the charged up powerbank – and the cable – in your pocket, purse, backpack, briefcase or whatever and use it to charge the phone (using the same USB cable) when you see the battery meter sinking into the sunset.

Now the old solution was maybe go sit in your car in some parking garage to use your car charger, or maybe sit and wait in a food court somewhere where you miraculously found an outlet to plug into. You don’t like to admit it, but in many cases you’re screwed without your smart phone. So what’s the new solution to the, oops I’m out in the world with a dead phone and no charger, problem? Portable power banks.

If you’re the type who winds up standing in the street under an umbrella late for something or other and staring at the little Apple symbol on a black screen as your iPhone powers off just before the email you needed to look at loaded, then listen up. Let’s talk 21st century solutions. Lets talk accessories that solve modern life’s little problems.
