How does a Portable Power Bank work?

A power bank is basically an external battery in its own sealed case. Power banks usually come with a USB cable, so you can connect it to a power source such as your laptop or your phone. The great thing about having a power bank is that you can carry it, cable and all, in your pocket, purse or backpack. And when you see your battery sinking, all your have to do is simply plug your laptop or phone in with the USB cable!

We’ve all been in the situation when you’re out, you’ve got a million things to do and you need your smartphone to send an email or make a call, and alas – your battery is dead! And now that load shedding is basically a regular occurrence, we also find ourselves in a situation where we can’t use our smartphones or laptops because the power has been cut!

Now the old solution would be to maybe go sit in your car in the parking lot and use your phone charger, or find a restaurant with an outlet to plug your charger into. It’s hard to admit, but without your smartphone – you’re screwed. So what is the solution to this problem? Portable power banks.

So, how do they work? Power banks are comprised of a special battery in a special case with a special circuit to control power flow. They allow you to store electrical energy and then use it later to charge up your electrical devices. Power banks have become very popular because of the dreaded load shedding and because the battery life of our beloved phones, tablets and laptops have become

outstripped. By keeping a battery backup close by, you can easily top-up your devices.

Power banks can be used for just about anything; cameras, GoPros, smartphones, tablets, portable speakers, MP3 players and GPS systems. Practically anything you really need can be charged with a power bank – you just have to remember to keep your power bank charged too!
