Keep finding your devices run out of charge at the worst moment? You need one of the best power banks or portable chargers to top things up as and when needed. 

The best power bank for you depends on what you need to charge and how much juice you need away from the mains. Phones are the most obvious device to recharge during a long day out but you may also need a power bank that is able to boost the battery of a Nintendo Switch or even a laptop. 

Before making a purchase, think about the three Ps: price, power, and portability. Consider these things and you’ll find the right portable charger for your needs. Do you need it to top up your phone when you’re at a sporting event or on a night out? Or are you going camping for three days and need to charge several devices more than once without access to any wall chargers?

Pay attention to the mAh rating. The higher the number, the more charge the portable power bank will hold. You should also check how fast it can output charge as, if you’re relying on it to charge a large device like an iPad or laptop, you might be waiting around a while if the output is slow. 

Below we’ve listed the best portable chargers according to capacity, slimness, and port selection, as there's no one size-fits-all solution to this purchase. Make sure to read the full descriptions of each power bank to see which best suits your needs and budget.
