Duracell Power bank 20100 mAh, Portable Charger with Fast Charge Technology IN / OUT

Product Information

This year, a team at the University of Texas at Dallas published findings in the journal Nature Nanotechnology to show that they will soon be commercially viable, since molybdenum – a metallic element often used to strengthen and harden steel – can be combined with sulphur to improve stability and compensate for poor conductivity. It takes around three hours to charge from empty (considerably less time than the Juice Power Station), and once charged, Belkin says its tests show that charge will not diminish by more than 50pc even after a year’s time left dormant – all very impressive, and useful. Versatility is also worth considering – for example, can you use the charger for multiple devices? What devices is it compatible with? Does it offer pass-through charging (which means you can charge the bank itself, while using it to charge a connected device)?

And that's basically what I did. The power bank came in handy when trying to locate a friend to meet for a swim on Hampstead Heath (my phone was on its last legs – isn't it always?), and during last ditch attempts to keep my nieces and nephews entertained with games on long journeys (there’s only so much I Spy any sane adult can handle). Why we like it: The Daddy of the power banks we reviewed. Powerful, well designed, not too heavy, and brilliantly priced. It looks metallic, but the case is actually made of plastic polycarbonate, which houses the lightweight lithium-ion polymer battery cells that power it. Again, it has two USB ports, one that has a 2.4A amperage, and one 2A, and four LED indicators that show the battery level. Meanwhile, lithium-sulphur batteries might be a more practical stepping stone: they’re less expensive to make, weigh less and store almost twice the energy of lithium-ion batteries, and are better for the environment. However, sulphur is a poor electrical conductor, so the technology still needs developing.

Switching off data usage for apps you don't need will save your battery as well as your data usage. The best idea that Duracell have had with their power banks is their "pay for what you need strategy". They've released three power banks ranging in size from 3k to 10k. The former will give you one or two charges while the biggest will give you up to five. If, like me, you're constantly low on battery – and manically texting friends to let them know that you're about to completely run out of juice – then you may be in need of a power bank or portable charger to keep your smart phones, tablets, laptops and other devices up and running on the go

COVERAGE: The plan covers all defects & malfunctions under the original manufacturer’s warranty. The plan starts the day after the manufacturer’s warranty ends. It does not cover physical or liquid damage, accessories, consumables or parts that are not covered under the standard manufacturer’s warranty. The Juice Power Station boasts a lithium battery with a charging capacity of 11,200mAh. For me, that's plenty: enough juice to provide more than six smartphone charges, or fully charge an iPad Air. If you need more power on your weekend away, you might need to do something about your screen usage...Another point of difference which makes the Moshi IonSlim 10k stand out as are the battery's lithium-polymer cells, which have no ‘memory effect’ (an effect observed in some rechargeable batteries that causes them to hold less charge over time, because the battery appears to "remember" a smaller capacity). You can charge the IonSlim as frequently as you wish; it should stand the test of time. Why we like it: The best looking of the lot – and capable of providing a MacBook Pro with a 40pc power boost. So, brains and brawn.

It's a charming look though the plastic case can't help but feel a little less premium than some of the other devices on this list. Still it feels sturdy and has a nice bright set of lights on the side so you can always see how much power you've got left in it.

Try to avoid letting the battery drop to 20 per cent. This is a bit of a Catch-22 situation, but it is far easier to charge up a phone when it has between 20 and 80 per cent battery. Running out of juice, and therefore being unable to access Google Maps, is no longer a viable excuse for standing someone up or missing a conference call.
