Most of all, the design has proved rock-solid and reliable, and we have one that’s still going strong after a couple of years of on-and-off use.

Any less and it’s really for emergency use only as they are more suited for topping up devices rather than fully charging them.Finally, we run a quick charge test to find out how much they can recharge our test smartphone in a 15-minute period. We’ll run you through the different specs and what to look for, then point you towards the best power banks on the market. Step up from the budget power banks to the mighty Juice Powerbank Max and you get a much more capable mobile charger, with a 20,000mAh capacity and a 20W USB PD output over USB-C.

The best power bank if you want 3 full charges for your mobile, with the ability to charge an average smartphone from 0-50% in only fifty minutes.And while we’ve seen some superb long-life smartphones recently, you can still find you’re running out of charge before you can get near a socket, especially if you’re playing games or streaming video. Handily all the models are numbered not by what is the latest model, but by the number of charges they can supply an average smartphone. The Juice JUI-PBANK-3-ECO-FGR is so-named because the manufacturer claims it can charge your mobile phone three times before going flat.

What’s more, the wired charging isn’t super-speedy; our Android test smartphone only recovered by 11% from a 15-minute charge. Specialising in PCs, Macs, Mobiles, and so much more, we always aim to deliver an exceptional service. Certain items can take longer to source than the estimated week, particularly during busy trading periods and may take longer to arrive at our warehouse. This cable is so small though, and with Micro-USB usage almost non-existent, it’s pretty much useless.being the smallest with a single full charge (or less than in the case of my phone) however the largest is the exception to the naming rule with the ECO MAX capable of 7 complete charges when full. This time only charging Apple devices but being incapable of charging any android, disappointing as everything I own is android. I spoke to Juice who were happy to replace it and offered the Eco 2 instead, a product from the same range but the next size up in capacity. In fact, with bigger power banks, you can get away for a weekend or go camping and still keep your phone juiced up. Most purchases from business sellers are protected by the Consumer Contract Regulations 2013 which give you the right to cancel the purchase within 14 days after the day you receive the item.

It’s also a lot slower charging than USB-C which its capable of using, so really its inclusion is a bit of a oddity.Most power banks now use a USB-C port to recharge, although some models will have a micro-USB port as well to ensure compatibility with older chargers.
