In an ideal world, it's fair to say, there's no place for battery packs. Our smartphones should inarguably be doing better on the power front. Yet the reality is that battery life is still an issue for many users of even flagship devices. 

If you get through a day, you're lucky in many cases, especially if you're 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. What's changing now is the advent of super high capacities, most notably 20,000mAh, and USB-C. Those two things together means that some of these packs will even charge laptops, too. 

So without further ado, here's our selection of the best power bank options out there.
