EasyAcc Monster 26,000mAh Power Bank

There are a lot of high capacity portable chargers on the market. Some of them deliver just more than a high capacity and some of them just deliver a high power capacity that lacks heavily in other areas which ultimately makes it a mediocre power bank.

High capacity power banks are supposed to represent more than just a high capacity, they’re supposed to push the envelope of what it means to be a portable source of energy.

It’s the tech to go with the charger and the design that makes it portable is what’s also supposed to excel at the same time. So it matters what you can do with a large amount of capacity that you’re given and your experience with the large capacity matters just as much as the capacity itself.

Let’s see if this EasyAcc Monster has more to offer than just boasting a high capacity.

Power Capacity:

So of course as you’ve read from the title of this review, this power bank has a power capacity of 26,000mAh but this capacity is not the one you’ll be receiving. The output capacity will be lower than 26,000mAh but how much lower it is, will depend on how you use it.

If you’re charging a single smartphone with this power bank that has 4 Output charging ports then you’re most likely going to be getting a 24,000mAh power capacity, the more ports you use, the more Amp current that you draw from the charger, which means more heat will be generated and more power will be lost during charging.

So overall, the real capacity is going to fluctuate, but if you’re talking about the average power capacity that you’re going to receive, then it’s going to be about 21,000mAh because this is assuming you’re charging anywhere from 1-3 devices at once.

A Very Large Power Capacity that is capable of a Lot

Charging 4 devices can put the Output power capacity into a lower ballpark but charging 4 devices at the same time is something we’ll get to in just a moment.

So with an Output power capacity of 21,000mAh or possibly even higher depending on how you use it, you can expect to charge many smartphones 6 times or more. For a tablet, you can charge them about 2 times or more.

Ultimately, the power capacity that you’re receiving makes this charger highly deserving of the title as “Monstrous” because this charger can very well go days or even weeks without being recharged.

It’s the type of power bank that you’d take with you on a long road trip, camping, or any other place where you think you’ll be away from a wall outlet for a while. Charging a single smartphone with this kind of capacity is only the tip of the iceberg.

Like many other high capacity portable chargers, there are many charging ports. the usual is 2 port way but in this case, the EasyAcc doubled that and this power bank has 4 Output charging ports.

So yeah, you can charge 4 USB charging devices at the same time but that’s not as good as an experience as you think it might be. Here’s why:

Output Charging: 5V/2.4A Per Port       4.8A Max Output

EasyAcc Monster 26,000mAh Power Bank

Powerful Charging Ports

Okay, so each of the 4 charging ports is capable of charging at 5V/2.4A but the max output is 4.8A.

This means that you can connect two iPads with this power bank and they will charge at their max speeds of 5V/2.4A.

When 2 iPads are connected and charging, this means that the Max Output of this power bank has been reached and once you connect another tablet, smartphone, or any other USB charging device, then the charging speed of the iPad will slow down.

This is because, at any one time, the power bank charger can only output 4.8A. So connecting a device to the charger with 2 iPads already connected will pull power from the iPads charging for the other device that’s connected to equalize the Max Output Current.

A Bit of a Low Max Output

This is the weakest point of the power bank. Its powering capabilities of charging is designed for a 2-port power bank, and not for a 4-port power bank.

If the charger had just two ports, then it would make sense because the 4.8A Output can be taken advantage of in a more whole way.

However, if you’re expecting each one of your devices that are connected to the charger to be charging at max speeds, then you’re most likely going to be disappointed. To make the best use of charging speed is to strategically use your devices with the charger.

So this means that charging two iPads and another device isn’t such a good idea, but charging 2 iPads alone will make for a great charging experience because both of them will be able to charge at max speed and be filled to full power capacity.

If you want to charge 4 smartphones at the same time, then that’s not a problem because most smartphones charge anywhere from the 1 Amp to 2 Amp range.

So is the charging speed of the power bank bad? Well, not really but it can be bad if you’re using it with devices that can take high Amperage current for charging.

Overall, if the power bank is being pushed to its limit with 4 devices connected to it, then you can expect each of the charging ports to deliver a max output of 1.2A to reach the Max Output of 4.8A.

Input Charging:  2 Micro-USB Inputs     5V/2.0A Each Port

EasyAcc Monster 26,000mAh Power Bank

2 Input Ports for Faster Recharging:

Something that is still new but gaining popularity is the use of two Input charging ports. The Anker PowerCore 26,800mAh is such a power bank similar to the EasyAcc Monstrous portable charger that also uses two Micro-USB Input charging ports.

This charger has two Micro-USB Inputs that are both capable of 5V/2.0A. So you can recharge the power bank at 4 Amps, but only if you’re using a 2 Amp wall charger, which we highly recommend.

This is because if you’re using a 1 Amp wall charger, then the Input charging speed will be lower than 2 Amps for each port and this will ultimately lead to slower charging. So it’s vital to use a wall charger that is 2 Amps or higher.

This kind of design is a great way to recharge high capacity power banks such as this one because they’re able to recharge relatively fast, and in this case, if you’re recharging the power bank at its full speed it can be recharged to full in about 7.5 hours.


It’s no surprise that a charger with its power capacity and its ability to charge 4 devices at the same time is going to be large and heavy. However, it’s not too big that you can’t hold it and not take it anywhere.

Size and Weight:

Large but still Portable

It has a length of 6.6 inches, a width of 3.1 inches, and a thickness of 0.9 inches. The monstrous charger weighs 1.2 pounds.

So it’s large and quite heavy; it’s easy to understand that this isn’t the kind of portable charger that is portable in terms of using it in your hands. It’s still a portable charger that is best used by setting it down and using it.

Or you can leave it in a bag and have your smartphone or any other devices charge while they’re in a bag. Ultimately, the EasyAcc Monstrous charger is large and heavy which is why it’s best used by setting it down and using it as a charging hub.

Functional Components:

As for the functional components, the charger is very organized by the way it’s designed. The 4 Output charging ports are lined up vertically on the same side with a LED flashlight next to them.

You can find the 2 Micro-USB Input ports on the long side of the charger and the power button on the opposite long side.

The power button isn’t used other than turning on the flashlight and checking the power capacity left on the charger. To turn on the flashlight, the power button is pressed twice, and to simply check the power capacity you can press the power button once.

Charging begins once you connect a device to the power bank.

Overall, it’s a great minimal design but we still think the flashlight is somewhat an unnecessary feature, but its purpose is quite clear if you’re in a dark setting. Also, the grip of the power bank isn’t that great with it being a glossy finish, it can slip from a hand easily.

Structure and Material:

The overall build quality of the charger is quite good. 3 main pieces connect to make the power bank whole and they’re all made of plastic.

Even with it being made of plastic, the charger still holds strong and it’s a wiser choice to use plastic rather than Aluminum because this way the charger is at least somewhat lightweight.


The functional pieces of the charger can function normally use after use but it’s the many charging ports and the max output is what makes the build quality of the charger wane a little bit.

If you’re taking full advantage of all the charging ports and most of the charging speed that this power bank is capable of, then it can warm up quite a lot.

EasyAcc has mentioned that they have a multi-safe protection system with many of their power banks such as this one but the temperature controller could use some work.

With a power capacity that can potentially last for days or weeks, with the ability to charge smartphones and tablets plenty of times; of course, this portable charger is reliable.

The charging speed is where it can get unreliable in cases when you’re pushing the charger too far and each device is getting a limited charging speed.

This is why you need to decide what devices or rather how many devices you want to charge at the same time to maximize the output of the charger.

The recharging speed is really important because there are two Micro-USB Input ports, which allows the monstrous power bank to be fully charged in about 7 hours.

So in terms of power capacity, this power bank is amazing. Also in terms of usage, because you can use this charger for days without recharging and all it takes is a 2 Amp wall charger via 2 ports to recharge this EasyAcc charger to its full capacity.

After that, you’re ready to rock’n roll for a few more days. However, the max output of 4.8 should be increased to provide a universal fast charging experience for more devices at one time.

It’s not the most portable but it can very well be used to as a charging hub and for times when you won’t be near a wall outlet for a while.



It has a high power capacity regardless of the power lost during different charging configurations and as a result, you can expect many charges for smartphones and a few for tablets.

The max charging Output could use some work with only 4.8 Amps of power to use at once. it may require you to pick and choose what devices you want to charge the fastest at any given time.


It’s a large power bank with a heavyweight. The functional parts are easy to find and use. For the most part, the power bank is hands-off as the charger begins charging when a device is connected to it.

You can use the power button to turn on the flashlight and check the power capacity.


There’s nothing special about the build. The power bank is made of plastic and holds strong with only 3 pieces holding the charger.

It does have heating problems if you’re using it near or at the max output of power.


It’s quite a reliable charger with a power capacity that can last for days or weeks. if you do use it all up, then there’s a fast recharge rate that can bring back the power bank to its full speed in a mere 7 hours.

If you’re thinking about charging 4 devices at their max speed all at the same time, then you’re going to be disappointed at your notice that the charger is only capable of a max output of 4.8A.

Like many other power banks, this one has its limits but it’s still quite good.

The power capacity will decrease depending on how you’re using it but overall the power capacity will still be considered as “High” and can last for days or weeks.

The charging speed is alright but you can’t go all the way with each of your devices because of the 4.8A max output speed. So you’ll have to realize that charging 4 devices at once may be an option but the quality of charging may decrease.

It’s a great design that the power bank has. It follows the same traditional size and weight with it being large and heavy. But it can still be traveled with and it’s great for those times without a stable source of power.

Just bring enough charging cables.
