Samsung is known for making awesome devices and one of their latest devices that they’ve released is their Galaxy S8 smartphone that provides a beautiful screen and some of the most powerful technology when it comes to mobile devices. That said, Samsung also makes some great tablets as well.

In this case, though, I’m talking about their Galaxy Tab S2 and the Galaxy Tab 4. Just like all tablets in general, they have very large batteries and the great part of having a very large battery is that you can use a device for a longer amount of time before they need a recharge.

However, when a large battery needs a recharge, then that’s when having such a large battery isn’t the best thing. As larger the battery the longer it will take for a full recharge to happen.

Getting the Most out of your Tablet Charging

The Galaxy Tab S2 and Galaxy Tab 4 have very large batteries and that is why it’s important to know what chargers to use with these tablets.

In this guide, we’ll be going over what the best chargers are for the Galaxy Tab S2 and the Tab 4 so you can get the best charging experience when it does come to recharging these larger devices.

Just a few things to know before you read on is that the Tab S2 has a capacity of 5,870mAh and the Tab 4 has a 6,800mAh capacity.

The max charging speed of these two tablets is 5V/2.1A. Both of these specifications are important to know so you can get the right portable charger with the right amount of power capacity and also so you get the charger that has a charging speed that can charge these tablets at their max speed.

Portable Chargers for the Galaxy Tab S2 and Galaxy Tab 4

Having a portable charger when it comes to these tablets can be quite tricky, as a portable charger has a power capacity and then you have to keep a lookout at the charging speed of the ports. As there are lots of portable chargers on the market that have a high capacity and yet their USB ports don’t give very fast charging speeds.

The use of lots of power and powerful charging need to both be present to have a great charging experience.

Anker PowerCore II

The Anker Power II portable charger is one of Anker’s latest high capacity power banks and it sure shows with the type of tech that it offers. That’s because it has a 20,000mAh power capacity and that results in it being able to charge a Galaxy Tab S2 or a Galaxy Tab 4 to its full power about two times.

Just remember though, these full charge estimates are based on charging the single tablet at a time and not charging any other device. As that will give you the most usage of power capacity that is available.

Even Faster Standard Charging

Another powerful part of this portable charger is its charging. The Output charging of this portable charger includes the use of 3-Ports and each of the ports has a charging speed of 5V/3.0A. The standard for most high capacity power banks is 5V/2.4A, so this charger can, of course, charge your Galaxy tablets at their max charging speed.

It doesn’t just stop at charging a single tablet at its max charging though, as this portable charger has a 6A Max Output and that means you can charge 3 Galaxy tablets at the same time and all 3 of them would charge near their max speeds.

Use Two Input Ports at Once

Then once it comes to recharging this 20,000mAh portable charger, the recharging is very fast. Most portable chargers that have a 20,000mAh capacity use a single Input port, but this Anker PowerCore II uses 2 Micro-USB Input ports.

Each of the ports has a recharging speed of 5V/2.0A and that results in a recharge speed of 4A when you use them both at the same time. As a result, you can recharge this power bank to its full power within just 6 hours, which is a very fast time for a 20,000mAh charger.

RAVPower 32,000mAh Power Bank

Since the Galaxy Tab S2 and Galaxy Tab 4 have very high power capacities, it only makes sense to want to get a charger that goes beyond the 20,000mAh power capacity. Such as this RAVPower 32,000mAh portable charger that basically has enough power to charge a Galaxy Tab S2 or a Galaxy Tab 4 to its max power about 4 times over.

Tons of Power Capacity with Three Ports

This is some very long lasting power that can very well last you for a good month if all you’re doing it recharging your Galaxy Tablet or other tablets such as an iPad. The other part that makes this RAVPower portable charger worth getting are the 3 USB ports.

The charging power from this power bank is quite similar to that of the above PowerCore II portable charger. As it has a 5V/2.4A charging speed with each of its ports and the max output of the power bank is 6A.

Each of the charging ports can charge a Galaxy tablet at it max charging speed and with the max output being at 6A, you can basically charge 3 Galaxy tablets at their max charging speed at the same time.

Charge Wisely but there’s Still Lots of Power

That said, just remember that if you’re charging lots of devices at the same time, then you’ll have less power that you can actually use towards charging your devices. As there’s more power lost during charging because the power is converting from your portable charger to the device that you’re charging.

The recharging of this 32,000mAh power bank isn’t the best as it only uses a single Micro-USB input port, so when it does come to recharging it, you should definitely do it overnight.

Pros for RAVPower 32,000mAh Power Bank:

• Has a massive power capacity that can charge smartphones and tablets to full power multiple times
• Uses three ports to charge multiple devices at once
• Each port can output 2.4A and the max output of the power bank is 6A
• Comes with two Micro-USB cables

Cons for RAVPower 32,000mAh Power Bank:

Four Ports to Charge Four Devices

There are four USB-A ports, and each of the ports has a charging speed of 5V/2.4A. While the max output of this power bank is 4.8A, so the more devices you charge at the same time, the more the max output will be split up.

So if you want the fastest charging speed form this power bank, it’s best to charge two devices at once. However, charging four devices at the same time can be very convenient.

Two Micro-USB Input Ports

Another great part of this EasyAcc Monster portable charger is its recharging and that’s because this charger has two Micro-USB input ports.

You can use both of the input ports at the same time, and since each of the input ports has a 5V/2.0A input; using them both at the same time will result in a 4A recharging speed.

• Uses a 26,000mAh power capacity that can be used to charge tablets and smartphones
