Best portable chargers: Keep your smartphone battery alive

por Natisha Holton (2020-06-12)

Whether you're heading to a meeting, on a long train journey or in a festival field, there's nothing worse than losing charge on your smartphone.

The dreaded feeling of not knowing where you or your destination is, coupled with the fact that you can't get in touch with anyone to find out, is one that is all too familiar. Battery anxiety is real, and very few smartphones can be trusted to last the whole day.

Portable chargers solve all of that. They are compact, mobile and can often hold enough power to charge your phone multiple times over. Here are some of the best portable power banks you can find on Amazon for all budgets, to keep your devices fully charged on the go.

Anker Astro E1 5200mAh Portable Charger, £10.99
One of the more compact choices in this list, the Anker Astro E1 and will only set you back £10.99, but it still packs a punch.

It is ultra-portable, fitting easily into pockets and purses, while its 5200mAh battery capacity is enough to charge your phone twice or power up an iPad. PowerIQ smart charging technology also recognises your device and optimises charging speed accordingly.

With an impressive average star rating of 4.5 out of 5 and over 10,500 reviews on Amazon, the Anker Astro E1 is already a very popular choice. As one happy reviewer states: 'This particular size is a great balance between size/portability and charge capacity.

'It's compact and lightweight but still holds around two full charges for your smartphone.'

Anker PowerCore 26800mAh Portable Charger, £39.99
The beast of this list, the Anker PowerCore has a colossal 26800mAh capacity which is enough to charge most phones over six times, tablets at least twice and any other USB device multiple times.

The PowerCore offers three USB output ports so you can charge multiple devices at the same time, with high-speed charging through Anker's PowerIQ and VoltageBoost technology.

Despite its huge charge capacity, the 7-inch long and 3.2-inch wide power bank is still compact enough to fit into your bag, although the 495g weight is on the heavier side.

The Anker PowerCore packs some serious juice and is recommended for larger devices and those going on a longer adventure. At £39.99, the PowerCore is at the higher-end of the price range for portable chargers, but it is well worth it for the extra piece of mind for when your phone is low on charge.

vooe Power Bank 25800mAh, £16.99 
An Amazon best-seller, the vooe Power Bank has a huge 25800mAh capacity, enabling you to charge your smartphone five to seven times. It also comes equipped with dual USB ports so you can charge two devices simultaneously, which is handy.

The large battery capacity does mean that the portable charger is on the heavier side, although at 350g it is still lighter than the Anker PowerCore.

With an average star rating of 4.6 out of 5, the vooe has received near-universal praise. One happy customer states: 'Excellent power bank, as good as other more expensive makes!'

It is one of the more stylish entries in the list, with a bold black and red colour design and four blue LED indicators, which blink or shine depending on its charging status and battery level.

The EC Technology power pack is a great choice for travel, camping or other outdoor activities. As one reviewer simply states: 'If you suffer from battery anxiety, this is the device for you.'

Despite its size, the device still holds a battery capacity of 5000mAh - enough to add two charges to an iPhone 8, and one full charge to an iPhone Xs Max.

The Slim 2 is an Amazon best-seller with 5,500 reviews and an average star rating of 4.1 out of 5 stars. For a budget, highly portable and lightweight option, the Poweradd Slim 2 is a great choice.
