Apple iPhone 6s Smart Battery Case

  • RRP: £99, US$99

Apple has its own iPhone 6/6s battery pack case called the Smart Battery Case, which is available in White or Charcoal Grey.

It looks a bit peculiar - it's a fairly standard silicone case that allows you to easily insert and remove the iPhone, but with an extra portion that bulges out from the case and houses the battery, which should give you up to 25 hours more power.

What's interesting is that Apple has added an intelligent battery status that works with the case to show you how much charge you have left on the phone and case, and that information can be found on the iPhone lock screen and in the Notification Centre. It's also charged via Lightning cable and not Micro USB like many others in our roundup.

Apple iPhone 7 Smart Battery Case

  • RRP: £99, US$99
  • Buy from Apple

Following the initial scepticism about the design of the Smart Battery Case, it turns out it's a very well performing, useful accessory.

The one downside to having this new edition for the iPhone 7 is that it costs more than the original did. Both the 6s case and the 7 case now retail for £99. It's a high price no doubt, but it is very good, and will make your iPhone 7 last the best part of 2 days.

Quite a few people made fun of Apple’s new Smart Battery Case, pointing at the inelegant ‘hump’ that houses the battery on the back of the case. To be fair, that’s a problem with most battery cases as they’re inevitably going to be bigger and bulkier than a simple sleeve that just protects against bumps and scratches.  

However, Tylt has come up with an ingenious solution to that problem, in the form of its Energi Sliding Power Case. The Energi starts with a simple, slimline protective case that wraps around the iPhone just like any normal case. If you don’t need to top up your battery then you can just use this case on its own so that it adds hardly any weight or bulk to your iPhone.

The clever part is that the battery is housed in a separate sleeve, and when you need some extra power you just slide the protective case into the battery sleeve and start charging. It’s a neat idea, as it means that you can keep your iPhone protected all the time, but you only need to add the extra bulk of the battery pack if you think that you’re likely to need a top-up at the end of a long day. The battery capacity varies – it’s 2500mAh for the iPhone 5 model, and up to 3500mAh for the iPhone 6S Plus – but is generally enough to provide a full recharge for your iPhone.

RRP: from £129.95
Get one from Mophie

Mophie is one of the most well-known manufacturers of cases and chargers, with a wide range of products for iOS and other devices. Its Space Pack cases are among its most expensive products, but they do a lot more than just charging up your battery.

There are models available for most recent iPhones – and even for the iPad Mini 2 and 3 too – and as well as providing a full battery recharge for each device, the Space Pack also manages to squeeze in some extra storage too. The iPhone models offer either 32GB or 64GB of storage, while the Space Pack for the iPad Mini goes right up to 128GB of storage. Apple is still selling iPhones and iPads that only have 16GB of built-in storage (boo, hiss…) so the Space Pack is a useful way of adding extra storage to your device, while also getting a protective case and extra battery life too.

Mophie’s Space app can be used to keep your files organised, and even allows you to transfer files onto a Mac or PC via a wifi network. Admittedly, the combination of a battery pack and extra storage means that the Space Pack cases are a little chunky, but that does give Mophie room to build some special shock-absorbing bumpers into the case in order to provide maximum protection for your iPhone. Alternatively, Mophie also sells a version called the Space Station that consists of an external battery pack with up to 64GB of extra storage, which you can use if you’d prefer to keep your iPhone in a slimmer, lighter case.


Techlink Recharge 12000

  • RRP: £79.95

Works With: Any iPhone, iPad

TechLink mostly makes external battery packs, rather than charging cases – and they’ve just released a neat one for the Apple Watch too – but if you just want a powerful battery pack that will keep you going for as long as possible then the Recharge 12000 is a good, no-nonsense solution.

As the name implies, the Recharge 12000 houses a powerful Lithium-Polymer battery pack that can store up to 12000mAh of power when fully charged. That’s enough to charge an iPhone 6 five times over, or to provide one full recharge for an iPad Air, so you can be sure that you’re not going to run out of juice even on a long plane or train journey. It’s got two USB ports, so you can charge two devices at a time, and the Recharge 12000 is smart enough to know when your devices are fully charged so that it can stop charging and avoid overloading the battery.

The Recharge 1200 includes both Lightning and micro-USB cables, so you can use it with non-Apple devices if you need to, and there’s a carrying pouch included as well.

Admittedly, the size of the battery means that the Recharge 12000 is one of the bulkier chargers currently available – it’s as big as many portable hard drives, and weighs in at just under 300g. However, Techlink has turned that into a virtue by incorporating a fold-out stand that can support an iPhone or an iPad so that you can sit back and watch some video while they’re charging.


JBL Charge 2+

  • RRP: £149.99

Works With: Any iPhone or iPad

There are a few speakers around that will allow you to use their internal battery to top-up your iPhone every now and then, but JBL’s new Charge 2+ is a versatile, portable option that you can easily carry around when you’re travelling.

The Charge 2+ is a cylindrical speaker that measures about 7-inches long and weighs about 600g, so it’s easy to slip into a backpack when you’re on the move. It works well as a portable speaker, with Bluetooth connectivity, and a bass radiator that gives it a nice, strong sound. There’s also a noise-cancelling microphone for taking phone calls too. 

The rubber casing of the Charge 3 provides good protection for bumps and drops when you’re in the great outdoors. It’s even rated IPX7 for water-resistance, which means that it can cope with being submerged in up to 1m of water, so it’s a good choice if you’re out in bad weather or splashing around on a beach. You can link multiple Charge speakers together to really pump up the volume, and there’s a Social mode that lets you pair it with three Bluetooth phones or tablets all at once so that your friends can join in and play their own music too. 

Despite its compact size, the Charge 2+ manages to squeeze in a powerful 6,000mAh rechargeable battery. That should last for up to 12 hours when just playing music, but it can also fully recharge most iPhones and still have enough juice left to keep playing music for a few hours too.


Braven BRV-Bank

  • RRP: £139.99

Works with: Any iPhone or iPad

It’s a bit pricey, but the BRV-Bank is the sort of battery pack that Batman would have for his Bat-iPhone.

It’s fairly chunky, measuring about 75mm wide, 126mm long and 22mm thick, so you’d probably need to carry it in a jacket pocket or a backpack. However, some of that size is down to the tough water-resistant rubber jacket that helps to keep it safe even in rough weather.

The size of the device means that it can squeeze in a high-capacity 6000mAh battery that is capable of charging an iPad Air up to around 60%. It also has a pair of USB ports that will allow you to charge two devices at once, and even includes a little torch attachment to help you out when you’re fumbling around in the dark. And just to show off a bit more, the BRV-Bank includes Bluetooth wireless connectivity so that you can connect to the Braven app on an iOS device. This app lets you monitor the battery level, and can be used to remotely activate or deactivate each of the charging ports. The app can also trigger a beeping noise to help you find the BRV-Bank in the dark, and in an emergency, it can even activate a morse code SOS signal using the torch attachment


EasyAcc 15000mAh

  • RRP: £79.99, US$79.99

Works with: Any iPhone or iPad

EasyAcc has high RRPs on Amazon, but they are never sold for that much - the products are quality though, so don't think this is some knock off. They are excellent value, and this 15000mAh pack is no exception.

To put its power into perspective, EasyAcc claims this particular bank can, when fully juiced, charge an iPhone 6 5.5 times. If you leave the house and you'll be away from a plug for a couple of days, it could be all you need.


Nomad slim leather charging wallet

  • RRP: £99.99, US$119.95

This neat little wallet from Nomad looks like a classic leather card holder, but there's a 2,400mAh battery in there with a small Lightning connector.

It's designed for any iPhone with Lightning (so iPhone 5 and later) but you could top up an iPad too. It charges via the supplied micro USB cable and holds 4 cards, plus has a little pocket for notes or coins.

A smart way to carry your essentials and a charger.


Kanex GoPower

  • RRP: £49.95
  • Buy from Kanex

Works with: Any iPhone or iPad

The GoPower from Kanex doesn’t have the fancy bells and whistles of some of its rivals – there’s no app, no Bluetooth, and it won’t boil the kettle for you – but it provides a powerful little battery pack at a competitive price. 

The GoPower measures 98mm wide, 141mm long and 51mm thick, so if you can fit an iPhone 6 into one trouser pocket you can probably fit the GoPower into another pocket as well. It also includes a carrying pouch for when you’re on the move, and a little fold-out panel that lets it act as a stand for your phone so that you can watch some videos while it’s charging.

The battery pack has a capacity of 6000mAh, which should charge most types of phone twice, and it has two USB ports that will allow you to charge two devices at the same time. It’s one of the cheapest battery packs that we’ve seen with that capacity, so it’s good value for money. Our only minor complaint is that the maximum output is only 2.1A – compared to 2.4A for some of its more expensive rivals – and that means that it will take a little longer to charge more power-hungry devices like an iPad or iPhone 6s Plus.


Savfy Battery Case

  • RRP: £29.99

Works With: iPhone 6/6s

The Savfy Battery Case for iPhone 6 and 6S is remarkable value at £21.99, which is how much it cost on Amazon UK (US$30.99 on at the time of writing.

Although around the same weight as the Mophies, because it’s slimmer it feels lighter and more portable. Its 3,100mAh battery capacity is impressive, and will easily give you a full recharge, with some left over for later.

It’s a two-part design, with a solid-looking plastic bumper and hard-shell backplate, which features a handy LED battery-level indicator. You fit the iPhone into the backplate, then snap the bumper over.

At 102g it’s around the same weight as the other recommended iPhone battery cases, although the Tylt Slider’s clever two-part design is still our favourite for lightweight protection and a separate battery case only when you need it.

Apart from its lightweight and apparently robust design, plus decent battery capacity, the main appeal of the Savfy Battery Case is it’s online price of just £21.99 on Amazon. You can find even cheaper iPhone battery cases online but this is one of the best at this pricepoint that we’ve tested.

It comes with a charging cable and pass-through jack so that angled headphone jacks will fit.


LinearFlux LithiumCard

Works with: Any iPhone or iPad

The LithiumCard isn’t the most powerful battery pack available, but it’s very slim and light so you can easily slip it into your pocket and carry it around with you all day long.

Its capacity of 1200mAh is relatively modest, so it’s not the best choice if you want to the Lord Of The Rings trilogy on your iPad on a long plane flight. However, it only measures 5.5mm thick and weighs just 47g so it’s ideal to carry around when you’re on the move and just want to give your iPhone a quick top-up at the end of a busy day.

It’s cleverly designed too, as it includes a built-in Lightning cable that folds out from the side of the LithiumCard, and the cable is even reinforced with Kevlar for added protection. There’s also a reusable ‘nanostick’ pad that you can use to attach the LithiumCard to the back of your iPhone.

The use of the Lightning connector means that the LithiumCard won’t work with older iOS devices that use Apple’s original 30-pin connector, but it does also have a micro-USB port that will work with quite a few non-Apple smartphones as well.


Monster PowerCard Turbo

  • RRP: £12.97
  • Buy from Currys

Works with: Any iPhone or iPad

Monster is a great manufacturer of handy sized battery packs that still pack a punch. This model has a 3,350mAh battery that charges via micro USB, which is enough to charge a smartphone around 1.5 times, and certainly top up the majority of most tablets close to full.

The company has also got basketball legend Shaquille O'Neal to promote the PowerCard, which is always going to be a plus.


Mophie Powerstation Duo

  • RRP: £79.99

Works with: Any iPhone or iPad

The Powerstation Duo shown here has a chunky high-capacity battery that is powerful enough for both the iPhone and iPad. 

The Powerstation Duo measures a full 110m long and 26mm thick, so you’ll need to carry it around in a backpack or bag when you’re travelling. However, its large battery has a capacity of 6000mAh, which is enough to recharge an iPhone 6 twice, or give an iPad Air about 60% top-up. You could even charge both devices at the same time as the Powerstation Duo includes two separate USB ports for connecting mobile devices, along with a third micro-USB port that is used to charge the Powerstation itself.

It’s also quite solidly built, with a smart and sturdy metallic case that should be able to cope with life outdoors when it needs to. It may not be as convenient as the Power Reserve but the Powerstation Duo will be a really good option if you and some friends need to keep your phones charged up when you’re out on a long cross-country hike.


Mophie Power Reserve

  • RRP: £39.99

Works with: Lightning cable iPhones or iPads

Mophie's Power Reserve really is designed to be pocket-sized - in fact, it even comes with a keyring attachment so that you can keep it with you at all times.

The Power Reserve measures just 72mm long, 38mm wide and 14.5mm thick, so it's certainly easy to carry around if you do decide to keep in your pocket or in a bag. It's available in a number of different colours, and there's a quick-release button that lets you detach it from the keyring when you need to use it. 

That compact design means that its battery capacity is relatively limited at 1350mAh, and Mophie says that it is primarily intended for use with the iPod or iPhone rather than larger devices such as an iPad. Even so, that should be enough to give you about 50% extra charge and keep you going for a few more hours.

There’s a Lightning cable that folds out from the side, but – apart from a USB connector to charge the battery itself – there are no other connectors, so you won’t be able to use it with older iPods and iPhones that use the original 30-pin connector.


Patriot Memory Fuel+

  • RRP: £62.99

Works with: Any iPhone or iPad

There are several models in Patriot’s Fuel+ range, but the model shown here has a capacity of 9000mAh, which makes it one of the most powerful battery packs currently available for iOS and other mobile devices. Patriot also makes a 12000mAh model, for those that need more juice.

The Fuel+ is fairly chunky, measuring about 25mm thick, 93mm wide and 114mm long, but you could still fit it into a jacket pocket or backpack easily enough. The 9000mAh battery is powerful enough to recharge even an iPad Air, so it's a good choice if you want to watch a few episodes of Game Of Thrones on a long plane flight or train journey.

It should be able to charge your devices quickly too. It has two USB ports so that you can connect and charge two devices at a time, and one of those ports has 2.5A output that is higher than most of its rivals, so you'll be able to charge larger devices without waiting all day long. There's also a 'passthrough' option that allows you to charge the Fuel+ from a mains socket while also charging your mobile devices at the same time.


Works with: iPhone 5/5s, 6/6s, 7
RRP around £89.95

Battery cases are a bit of a mixed bag - they provide extra power and protection for your iPhone, but they’re often rather large and chunky and can spoil the look of the iPhone's slimline design. However, Mophie's Juice Pack Air is slimmer and more elegant than many rival cases, while still providing a really big boost to battery life when you need it. 

The latest model for the iPhone 6 and 6s looks very much like a conventional protective case, with a tough rubber housing that can withstand bumps and drops. We also like the raised bezel around the edge of the screen, which helps to protect it when you place it face down on a flat surface. The case does obscure the ports on the bottom edge of the phone, but Mophie includes a headphone adaptor and micro-USB cable so that you can still charge the phone and listen to music without having to remove the case.

And, despite the slimline design, the Juice Pack Air manages to provide a battery capacity of 2750mAH, which is enough to completely recharge the iPhone 6/6s.


Cobra JumPack

  • RRP: £99.99

Works with: Any iPhone or iPad (or car!)

The Cobra JumPack is a bit chunkier than many of its rivals, and is about the size of a pack of cards. Even so, it's still small enough to slip into a jacket pocket or backpack when you're travelling - or to stick into the glove compartment of your car, where it's particularly likely to come in handy.

The size of the JumPack also means that it packs some serious battery power, with a full 7500mAh capacity. That’s slightly more than the capacity of the battery in the iPad Air 2, so it'll be able to recharge most phones and other mobile devices with no trouble at all. In fact, the manufacturer claims that in an emergency it can even jumpstart a car battery too. The JumPack also has a built-in torch to help you out if your car grinds to a halt a night, and there's an SOS strobe option for extra visibility. 

The manufacturers include both a conventional wall-charger for the JumPack, and an adaptor for a car cigarette lighter - and you even get a set of jump leads for your car thrown in, too.
