Best Power Banks for Samsung Galaxy S8

(Last Updated On: April 21, 2020)

Samsung is always about innovation and that shows with their smartphones especially with their Galaxy smartphone series. We’ve got their newest smartphone that is currently available on the market which is the Galaxy S8 and they went even further than the S7.

It has the all-new Qualcomm 835 processor that is going to provide you with amazing performance and also, the Infinity screen has become the norm with this phone.

One of the most important features for us here at Charger Harbor is the battery and the charging experience that you’re able to get from the smartphone. The Galaxy S8 is a smartphone that uses USB-C for charging and it uses Quick Charge 2.0 for its fast charging speeds.

Many people find it a disappointment that Samsung has gone a step back but they’re just being cautious for now with what the charging has to bring. That said, future updates for the smartphone could enable it to use Quick Charge 3.0 and even the next level Quick Charge 4.0.

The battery of the Galaxy S8 and S8+ are high. As the Galaxy S8 has a battery capacity of 3,000mAh and the capacity of the Galaxy S8+ is 3,500mAh. This is a great power capacity because this smartphone is going to need it with its capabilities.

Of course, just like all things, the Galaxy S8 will lose its battery capacity and requires a recharge.

That is when a good quality power bank will come in handy because you’re going to be able to keep using your powerful Galaxy S8 while you’re recharging it on-the-go.

Let’s take a look at some of the best power banks for the Galaxy S8.

Power Banks in this Guide:

#1: Anker PowerCore+ 10050 with Quick Charge 3.0

The PowerCore 10000 series of power bank from Anker is, of course, the versions of power banks that have power capacities that are within the range of 10,000mAh. What makes these power banks so good is the fact that they’re so small and still pack a punch.

There are quite a few Versions of the PowerCore+ 10050

One of the best aspects of the PowerCore 10000 is that different versions can provide certain charging experiences. The base Anker PowerCore 10000 has a 5V/2.4A charging speed which is great for Non-compatible Quick Charge devices.

Then there’s the PowerCore+ 10050 with Quick Charge 2.0 that you see above and that is the one that we’re going to be focusing on. Lastly, there’s the PowerCore Speed 10000 that features Quick Charge 3.0.

Using the PowerCore+ 10050 or the PowerCore Speed are the Best for Galaxy S8

These two power banks have enough power to charge the Galaxy S8 to its full power about two times. You’re probably wondering why it can’t charge the smartphone about 3 times, well that’s because the Galaxy S8 is going to be using very fast charging speeds of 5-6V ⎓ 3A / 6-9V ⎓ 2A / 9-12V ⎓ 1.5A and that worsens the conversion of power capacity.

However, two full charges for a smartphone that either has a 3,000mAh battery capacity or a 3,500mAh capacity is good because that full charge is going to last you for a while.

Another good part of the PowerCore+ 10050 power bank is that its Input for recharging also uses Quick Charge to recharge the power bank faster. Just make sure you’re using a Quick Charge USB wall charger for recharging the power bank.

Pros for Anker PowerCore 10000

  • Has a 10,000mAh power capacity that can charge the Galaxy S8 to full power about two times
  • Features Quick Charge 3.0 for fast charging
  • Compact size that can fit into your pocket

#2: EasyAcc MegaCharge 16,750mAh USB-C Power Bank

When it comes to power banks, it’s more about quality rather quantity and that is what this EasyAcc MegaCharge power bank offers with its charging powers.

How good is the charging Experience for a Galaxy S8

The EasyAcc MegaCharge power bank has quite a lot going on with it because it has a 16,750mAh power capacity that can charge a Galaxy S8 to its full power about 4 times. Galaxy S8+ can charge to its full power about 3.5 times.

One of the main things to note is that there are two USB ports and each of them has a base charging speed of 5V/3.0A.

One of the USB ports though uses Quick Charge 2.0 which has a charging speed of 5-6V ⎓ 3A / 6-9V ⎓ 2A / 9-12V ⎓ 1.5A. So you can have two Galaxy S8 smartphones charging with this power bank with one charging at its max speed and the other port charging near its max speed.

The best part is that the Max Output of the power bank is 6 Amps so you can use each of the two powerful ports with this EasyAcc power bank at the same time at their max power.

The Recharging is what takes the Cake

Not too many people think about recharging for a 16,000mAh power bank. It’s good with this one though because there are two Input ports for recharging the power bank. There’s one USB-C Input port and there’s also a Micro-USB input port.

The USB-C input port has a recharging speed of 5V/3.0A and the Micro-USB port has a recharge speed of 5V/2.0A.

Overall, the recharge speed of the power bank is 5 Amps and that results in the power bank being able to recharge to its full power within just 3.5 hours.

It’s a great recharging experience for Galaxy S8 users because you’re going to be using a USB-C to USB-A cable when you’re charging your smartphone and for when you’re recharging the power bank too.

When you have a smartphone such as the Galaxy S8 you’re going to want a power bank that has a lot of power to use because the S8 has a large battery. Which is one of the main reasons that this Jackery Max power bank is such a great choice.

#4: Puridea 20,000mAh Power Bank with Two Quick Charge Ports

The use of Quick Charge with a charging electronic can be very useful for those that can make use of the fast charging tech. That said, the use of two Quick Charge ports, isn’t very common, sure Anker’s PowerPort 5 charging station uses two ports and Aukey also has their Aukey 6-port charging station that also makes use of two Quick Charge ports.

That said, a portable charger using two Quick Charge ports is something that is not very common at all, but this Puridea power bank does use twp Quick Charge ports.

Well, there are three output ports with this power bank. With there being a USB-C output and the two Quick Charge ports. So you can charge two Quick Charge compatible devices at their max charging speed.

There are also two input ports with this power bank, but they can also be used once at a time. With the USB-C input having a recharge speed of 5V/3.0A and the Micro-USB input can recharge at Quick Charge speeds.

No matter what input you’re using with this power bank, it’s best to use a Quick Charge wall charger to recharge it at max charging speed.

When a power bank has lots of features, it could be a good thing or it could be a bad thing because having lots of features doesn’t mean it holds value. Luckily, this RAVPower power bank does hold lots of value with its features.

This power bank has a 20,100mAh power capacity and that enables it to charge smartphones like the Galaxy S8 to their full power about 6 times.

#9: Anker PowerCore 13400 Power Bank

pic-1

This Anker PowerCore power bank doesn’t have anything too extraordinary about it but it does have quite a bit of power and fast charging speed while still being able to maintain a small size.

The power capacity can charge a Galaxy S8 to full power about 3.5 times

For a power bank to charge a Galaxy S8 to its full power is good. However, when a power bank can charge a Galaxy S8 to its full power many times over, then it’s great because the capacity of an S8 can last quite long once it’s at full power.

Also, the portability of this 13,400mAh power bank is really good because it has a short and compact size that makes it able to be held in your hand for long periods; although it won’t be easy to fit into your pocket.

Charging Speeds

There are two ports with this PowerCore 13400 power bank and each of the ports has a charging speed of 5V/2.4A. Even though there’s no Quick Charge with this power bank, that’s quite alright because a 2.4 Amp charging speed is still fast.

The best part is that the Max Output of the power bank is 4.8A which means that you can use each of the two ports at their max power, which isn’t very common with 13,000mAh power banks.

Pros for Anker PowerCore 13400

  • Uses two standard ports
  • Enough power capacity to charge the Galaxy S8 to full power about three times
  • Comes with a Micro-USB cable

Cons for Anker PowerCore 13400

#10: Anker PowerCore II

Power banks with 20,000mAh power capacities are known to have good charging power, but they’re not known for going overboard. This PowerCore II does, in a way, as it goes very far with its powering abilities.

3 Very Powerful USB Ports

There are 3 USB Ports on this PowerCore II power bank and each of the ports has a charging speed of 5V/3.0A. Not exactly Quick Charge but it’s able to charge a Galaxy S8 close to its max power.

Another thing is that the max output of the power bank is 6A; which means that you can potentially use each of the USB ports at the same time with the 6 Amp Max Output being reached and each port would have a charging speed of 5V/2.0A.

Fast Recharging

Another great part of this PowerCore II power bank is that it uses two Input ports that each have a charging speed of 5V/2.0A and that makes the power bank able to recharge at 4A recharging speed when you use both Input ports at the same time.

This EasyAcc MegaCharge D20 portable charger is an upgraded version of the previous EasyAcc charger that we mentioned. This power bank has a 20,000mAh power capacity that can charge most smartphones and tablets to their full power many times over.

This isn’t the type of charger that you’re going to purchase to solely charge your Galaxy S8 and that’s because it uses four output ports.

There are three USB-A ports, with one using Quick Charge to charge compatible devices at max charging speed, the other two USB-A ports have a charging speed of 5V/3.0A.

The one other port is the USB-C port that you can use with a USB-C to USB-C charging cable to charge USB-C compatible devices such as the Galaxy S8. The USB-C port on this power bank has a charging speed of 5V/3.0A.

Recharging for this power bank remains the same as the other MegaCharge portable charger that we talked about. Meaning there are two input ports, with one Micro-USB and USB-C port.

3 USB Ports have 3 Different Charging Speeds
