Best Power Banks in the UK

The Anker PowerCOre+ is an upgraded version of the popular PowerCore series. Weighing almost twice as much as the standard PowerCore, it provides almost a 3-fold increase in battery capacity.

The main selling point of this portable battery pack is, of course, its capacity. With almost 27000 mAh under its belt (26800 mAh, to be precise), the power bank is capable of charging all modern mobile gadgets and most of the commercially available laptops that you can find.

Moving on, the plastic body of the appliance firmly protects the battery pack from damage while the internal MultiProtect safety system offers decent temperature control to the capacitors inside. On top of that, the portable battery boasts high-voltage protection, regulation of current as well as protection against undervoltage and overcharge.

Furthermore, to make the charging process of the actual power pack faster, the kit comes equipped with a 60 W adapter that is capable of charging the power bank to 100% in just a few hours. Like many modern models, this one uses a micro USB input for charging, however, for the fastest charging we recommend using the cable that comes equipped with the unit.

The Anker PowerCore III is the third iteration of the company’s most popular power bank model simply because it combines a compact size, decent capacity of the battery and relatively low weight in one single package.

First off, let’s take a look at the actual ergonomics that make this particular power bank great and which ultimately separates it from the rest of the models in the same price range. With a size of 149 x 68.5 x 19.5 mm, it fits inside pretty much any bag or backpack with relative ease as well as some medium-sized clothing pockets. Combined with a weight of 240 g, you are getting a highly portable battery pack that can handle a few full charges for your phone or tablet. To make your life simpler and to prevent the battery from potential scratches, the kit comes with a standard-size carry pouch.

As for capacity, there are no real improvements over the previous products of the same line. Rated at 10000 mAh, it offers the same punch for the buck as the second and first-generation PowerCores but this time around you can charge your mobile and other USB-powered devices almost twice as fast. The improvements we have noticed are related to the charging time, which is slightly faster than the previous iterations of the PowerCore.

The INIU 10000mAh power bank is arguably one of the thinnest and lightest chargers on the market. With a weight of 198 grammes and measured at just 13.21 x 6.86 x 1.27 cm, it fits snugly into any of your pockets, purse or small bag. On top of that, it meets TSA specs for gear, which means it has an approved size and built in 37Wh to be taken in a carry-on bag on flights, making it a great solution for travellers.

Aside from the portable dimensions, the INIU 10000mAh power bank stands out for its quality build. It's made from the premium materials and covered with an industry-leading 3 years warranty, giving you confidence that the unit will last you for a long while. Add to that a cute-looking LED charge indicator in the form of a little paw, which gradually builds up until the unit's fully charged, and you can get an idea how this power bank looks.

Naturally, looks are not the only strong point of the unit. From the practical point of view, INIU's power bank provides lots of desirable benefits, too. To start off, it comes with a good set of accessories, including a travel pouch and a micro USB cable. And secondly, it has a handy LED flashlight—a nice and handy bonus, which allows it to be used as a torch in emergency situations.

It's always upsetting to leave your charger at home or forget to charge your mobile gadget at all. Fortunately, with the Anker PowerCore at your disposal, you will forget that these issues ever existed. Sturdy, reliable, and capacious are perhaps the best words that you can use to describe this particular model.

To be more specific, the Anker PowerCore features a battery with a 20100 mAh capacity that will be enough to charge your smartphone several times and even fully charge a laptop once.

In order to keep the battery in good shape and to prolong its service life, the manufacturer recommends depleting the device's battery and fully charging it afterwards every 4 months. By doing this you won’t let the Li-ion cells inside the carrier disintegrate as fast as they normally would.

Thanks to an exclusive PowerIQ feature available only to Anker users, this model can charge your devices up to 40% faster than regular power banks. This is achieved via an 18W output power as well as the Intelligent Device-Detection that is able to identify the gadgets connected to the battery and adjust the output accordingly. 

The detection system also lets you set the charging speed depending on the battery of the device and currently supports Apple, Amazon Kindle, and Samsung mobile gadgets and products made by other major manufacturers. 

That being said, the device is well optimised even for the devices that are not currently supported. They won't, however, have the benefit of speed optimisation, leaving their charging a bit slower than we'd prefer.

JONKUU JPP-49 is one of those portable chargers that might look cheap at first but don’t let the appearance trick you, this power bank is still a formidable contender for the role of your favourite charging option, especially when it comes to charging mobile gadgets. So, what makes it special in the first place, you might ask? The answer is quite simple - compatibility with most of the modern mobile devices.

To start off, the internal battery pack offers up to 10000 mAh capacity, which enables charging even the most demanding phones up to 2-3 times with relative ease. To show up some numbers, the charger can fully juice up a Galaxy S8 up to 3 times, while the iPhone 7 can be charged from flat to a 100 up to 3 times. As for the newer 11 and 12 models, you should expect a full charge or two, the same goes for Galaxy S20 and similar Android devices like Pixel 4.

Certainly, 10000 mAh is simply not the biggest capacity that you can find for the price, that said, capacity is not the only thing that makes JPP-49 stand out. On top of the decent battery, we have a high-speed charging mode that puts slow charging rates of a standard power plug to shame. Using the dual 2.4 A USB output ports you should expect a 1.5 boost in charging speed while having two USB ports instead of just a single one enables charging two devices simultaneously. The only caveat to using two USBs at the same time being the tendency of the charger to get quite hot.
