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.

Switching off data usage for apps you don't need will save your battery as well as your data usage. Similar to the Juice Power Station, it also has an LED charging gauge so you can easily judge how charged up it is. Why isn't in our top three? Well, it's an ugly, clunky thing, truth be told, and it feels a little heavy. That said, I’ve long been a fan of Griffin accessories due to their impressive durability (particularly their phone cases); in general, it's a company you can trust. Power up on the go with our lightweight, compact Duracell Charge 10 power bank. With 10,000 mAh battery capacity, the Duracell Charge 10 can fully charge a phone up to 3 times*.

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. 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... 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.

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. 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.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. But which one is best? I tried a range of power banks at festivals, on camping trips and flights, as well as during the course of my everyday routine, and reviewed them with the size, weight, charging speed, ease of use and the warranty in mind. There are two payoff to all this. The first is that the product is more complicated to use than the Power Station or Belkin – you need to take care to get the right cable in the right slot (an exhaustive instruction manual makes this easy, if somewhat time consuming, to learn).

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. Precharged and ready to use straight away, this is a 10,000 mAh power bank offers around four full smartphone charges. It has two USB ports, so you can charge multiple devices (one 2.4A USB port and one 1A USB port) and is compatible with most devices.Why we like it: It's colourful, compact, powerful enough to fuel a long weekend away, and very reasonably priced. Good for teens and their parents. Another cool fact about Duracell's offering is that even the biggest is only 203g, considerably lighter than comparable products which is nice. Includes: Charging cable (USB-A to USB-C), 20cm 1 x USB-C - PD3.0 18W max input and output 1 x USB-A – 18W max output

The 4 LED display lets you know the level of energy the power bank has left, when it’s charging and when it’s fully charged.

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 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).
