Battery packs should be superflous but, as advanced as smartphones have become in recent years, battery life is still something they haven't quite nailed.

Some will last most of the day, others might get you through most of the evening too, but that's assuming you aren't spending all your time on WhatsApp, playing PUBG Mobile or stalking Facebook.

That's where our list of the best battery packs and portable chargers for smartphones comes in. They've been around for years so when it comes to your options, there are hundreds.

So without further ado, here's our selection of the best power bank options out there to make sure your phone keeps up with you.
