Best Power Banks for iPhone 6 / iPhone 6s

Of course, all power banks can be used with devices that are charged through a USB charging port. Ultimately, there’s isn’t a power bank that is made specifically for a certain device unless it has a built-in charging cable that is dedicated to a certain device. So for the most part, portable chargers can be used for nearly all smartphones and tablets.

However, there are certain power banks that are more favorable to use with certain smartphones and other devices. This is because of their traits like power capacity, charging speed and other facets all come together to make them a great match for a specific device.

In this case, we’ll be taking a look at power banks that are best to use with the iPhone 6, since it’s actually one of the iPhones that are able to charge at a quite a high charging speed than other, lower-grade iPhones. Also, the different variant of the iPhone 6 have some large battery capacities when compared to its predecessors.

#1: Anker PowerCore Slim 5000


The power capacity of this Anker PowerCore Slim doesn’t suffer too much during charging, and that leaves you with an Output power capacity for just enough charging for 2 or just 1 full charge.

If you’re charging a normal iPhone 6, then that can result in the iPhone 6 and iPhone 6s being charged 2 full times while still leaving just a bit more of power left. Charging the larger iPhone 6 models will most likely run you just a single full charge and that’s still lots of power because, with “Plus” models for the iPhone 6, you’re given very large battery capacities and just by putting a full charge back into your smartphone, it’s going to last you a long time.

Charging Power:

One of the most important aspects that this power bank other than its design is the charging power. The charging speed of a power bank matters because that’s when you’re actually experiencing using the portable charger. The slower the charging, then you’ll notice that your battery capacity has stayed the same for quite some time; and that’s the thing with most power banks, it’s that they don’t have very fast charging.

However, in this case, the Anker PowerCore Slim is one of the best power banks for the iPhone simply because it has an Output charging speed of 5V/2.0A. Okay, so that doesn’t meet the max charging speeds of the iPhone 6 because of the iPhone 6 able to have max charging at 5V/2.1A. This is still a fast enough charging speed, though, and you’ll notice that your iPhone 6 is being recharged a lot faster than your normal Apple USB wall charger that only Outputs 5V/1.0A; which is a much slower charging speeds.


The main reason other than its powering capabilities is that this Anker’s power bank form factor is spectacular. The PowerCore Slim is basically like carrying another smartphone around and that is a great thing; since it has a length of 5 inches, a width of 2.5 inches, and a thickness of 0.4 inches. The weight of it is also really light since it only weighs 4.2 ounces. So you can either hold it or place it into your pocket.

The best part about the design is are the details on the PowerCore Slim that makes using it very easy. On one side of the PowerCore Slim is a flat surface that has these ridges where you place your smartphone. The other side is curved. This kind of design makes it easy to use your iPhone 6 and while still using it normally as if you weren’t stacking it up against a power bank.

Overall, it means that you can be on a call while still holding both the power bank and iPhone 6 in a very comfortable manner.


Conclusively, the Anker PowerCore Slim has some of the best traits that a portable charger could have because it makes use enough power capacity, fast charging power, and a design that makes actually using the power bank along with your smartphone a pleasurable experience.

#2: Jackery Bar Premium


The power capacity of this Jackery Bar is quite good and the main thing about power banks for smartphones is that they always have to lend enough power capacity to smartphones for either 1 full charge or beyond; if that’s the case, then the power bank is already great to use with most smartphones.

With this Jackery Bar, it fairs very well with the iPhone 6 as you’ll be getting more than just one full charge with it at all times. For the iPhone 6 and iPhone 6s models, you’ll be able to get 3 full charges when the Jackery Bar portable charger is charged to its fullest extent. Charging even the higher battery capacity ones like the iPhone 6 Plus and iPhone 6s Plus will result in 2 full charges. Overall, whether you’re on the higher spectrum of the iPhone 6 or more standard part; this Jackery Bar can either last you 2 or 3 days without needing a recharge if you’re using it once a day to charge your iPhone 6 to its full power.

That’s a whole lotta reliability.

Charging Power:

Charging speed is maxed out at 5V/2.1A. This power banks only has a single charging port and it’s able to charge the iPhone 6 at its max charging speed. So let’s take a look at this in retrospect.

It’s not only able to charge your smartphone 2 or 3 times and for a few days, but it’s also able to charge it at its max charging speed. So every time that you do use the Jackery Bar, it’s a fast charging experience that results in you not always having the power bank plugged into your smartphone at all times.


Not the thinnest charger, but that’s really the function of it. However, the Jackery Bar is still really portable with its length of 3.8 inches, a width of 1.8 inches and a thickness of 1 inch. We understand that it won’t be fitting into any pocket, but it’s very manageable and easy to just hold the charger as you use your smartphone while it’s charging. This is possible because the power bank only weighs 5.4 ounces.


The Jackery Bar Premium hits just the right spots as being a power bank made for the iPhone 6 because it’ll be able to charge it at its max charging speed, as well as being able to charge it 2-3 full times before needing a recharge.

#3: Jackery Bolt 6,000mAh Power Bank


The power capacity for this Jackery Bolt power bank sits at a similar level as the Jackery Bar as it’s able to charge an iPhone 6 and 6s models about 3 times. Charging the larger Plus models will result in 2 charges or lower.

One of the best reason to get this power banks for your iPhone 6 is because it has a built-in Lightning charging cable and a Micro-USB cable as well. Of course, if you have an iPhone 6, or any iPhone that’s either the 5th or after version then you’re going to always have an available charging cable with you. In that case, you’ll never have to worry about bringing another charging cable with you on-the-go.

If we’re talking about the individual charging speed that this power bank has, it’s really good but the Max Output can be lacking. This is because it has a Max Output charging speed of 5V/2.4A and so if you’re charging 3 devices at once, it’s not going to be Outputting that much charging power to those 3 devices. With that said, let’s say you’re only using the Built-In Lightning charging cable to charge your iPhone 6; then it will be charged at its max charging speed. So the Jackery Bolt is best used for an iPhone 6 if it’s ONLY charging an iPhone 6.


For what it has to offer, the Jackery Bolt power bank is actually quite small. It just has a length of 4.3 inches, a width of 1.9 inches, and a thickness of 0.9 inches. The weight is also light because the Bolt only weighs 5.3 ounces. Ultimately, it’s not going to fit into any pockets but this charger will be able to be held in just a single hand while you use your smartphone.

You can especially use your smartphone easily because the charging cables that come out of the power bank are really short, and that means there’s not the hassle of dealing with long charging cables that unnecessarily get in the way.


The Jackery Bolt is perfect for the iPhone 6 mainly because it has a Built-in Lightning charging cable. So when you have this power bank, you won’t have to worry about carrying around a charging cable.

#4: RAVPower 6,700mAh Power Bank


Very similar to other power banks on this list, the RAVPower portable charger has a power capacity that can charge most iPhone 6 models about 3 times. So you can potentially charge your iPhone 6 for 3 days continuously without needing a recharge.

Charging Power:

With that said, the charging speed is more of the impressive part as it only has a single charging port and yet the charging speed of that port is 5V/2.4A. A charging speed of 2.4 Amps is a Max standard charging and you’ll see that a lot if you read our many power banks reviews. This basically means that the charging speed from this power banks and other power banks that charge at 2.4A are able to charge a device that doesn’t have Quick Charge or USB-C tech at their max charging speeds.

In this case, it would be iPhones; also if you really wanted to, this power bank can also charge iPads at their max charging speeds too.


It’s a really small power bank and we mean it. This is because the RAVPower portable charger has a length of 3.5 inches, a width of 1.6 inches and a thickness of 1 inches. It’s also really light at a weight of just 4 ounces.

The size of the power bank can very well allow you to place it into your back pocket, mostly because the charger is a little too thick to fit into a front pocket.


For its extremely small size, this RAVPower portable charger has lots to offer with the portability being so good that you can fit it into your back pocket. Along with the great portability, the portable charger has a Max standard charging speed that will charge your iPhone 6 at its max charging speed.
