Portable chargers are a game-changer for your smart devices. Compact and mostly palm-size, they're the perfect solution for keeping your phone or tablet up and running when on the go.

We've handpicked our top 12, which range from wireless designs with magnet pads to mini versions no bigger than a lipstick.

From cheap and cheerful power banks costing less than £15 to high-end models that are close to £100, our roundup has something to suit every need.

Whether it's ahead of a long car journey, lengthy commute, or airplane travel, a portable charger will ensure you're never caught out.

Featuring devices from big-name retailers such as Amazon, John Lewis and Currys, next time you're away from home, make sure you have one of these power banks full of juice in your bag.

Anker is one of the market leaders in power banks. This slimline design won't take up space in your handbag or workbag and is compatible with Apple, Samsung and Android devices. Once fully charged it can provide nearly 2.5 full charges for iPhones and over 1.5 charges for Galaxy phones.

This stylish power pack attaches to the back of your iPhone via magnets and charges it wirelessly, with no cables necessary. It also won't interfere with credit cards or key fob either and is lightweight enough that you'll barely realise it's there. It's not cheap but well worth the investment.

Another top seller on Amazon is this INIU Power Bank which boasts over 23,000 reviews. One reads: "At last, I can say I have found a decent-sized charger which ticks all the boxes. Delivery was prompt and when I opened the packaging it came with a USB-C cable. Perfect to charge my Samsung Note 20 Ultra."

Power banks don't have to be boring – this rose gold style from Belkin is a fun pop of colour for your handbag. It has three ports that support USB-A to USB-C cables and can add up to an additional 40 hours of battery life for your smartphone.

This is a great option if you're looking to spend less than £15. It's a two-pack, so ideal for your gym bag and work bag, has USB output ports and is compatible with iPhone, Huawei and Samsung Galaxy devices.

This fun power bank is perfect for festivals, flights, long car journeys and commutes. Designed for iPhone and Android users, it can deliver up to four hours of charging time.

Another stylish design is this sweet bee print one from Cath Kidston. It has universal charging capability, dual USB outlet ports, and a LED torch feature.

Another bargain power bank is this one from Juice. Slim and simple, it can charge two devices at once, can deliver three full charges for your mobile, and has a digital display to check remaining energy levels.

This portable charger is designed with outdoor enthusiasts in mind and can charge an iPhone XS up to seven times or a Galaxy S10 up to six times, as well as cameras and tablets. The solar panel can absorb sunlight and convert it into electrical power too, so even without electricity, you'll never run out of juice.

According to one happy shopper at Amazon, "On a full charge it has charged my phone up for over a week. The charger is showing that it still has 50% left. This is great for camping or travelling, for when you do not have access to a mains charger."

This wireless design attaches to your smartphone via a magnet and comes with a length 1.5m cable and USB-C connector.

Portable chargers don't get more compact than this. No bigger than a lipstick, it can fully charge an iPhone, comes with a USB-C cable and will come in handy if you're not near a plug socket.
