Review: EasyAcc 2nd Gen. 15,000mAh Power Bank

EasyAcc 2nd Gen. 15,000mAh Power Bank









  • High Enough power capacity to charge smartphone 4 times or more. Tablets can take 1 full charge.
  • You charge 3 devices at the same time, and the Max Output 4.8A means fast charging for nearly any device that you connect to this power bank.
  • Easy to use, with charging autmatically starting when devices are plugged in and stopping when there aren't any devices connected.


  • It's Large and Heavy, so it's best to just set it down and use it.
  • A even higher Max Output of 7.2A would have made it perfect without any compromises.

The more charging ports that a power bank has, then the more versatile it is.

This is the consensus with nearly all charging electronics actually, but when you have a power bank that has many charging ports, then its capabilities are that much better. Usually at least.

There are power banks with many charging ports such as the ZeroLemon that has 5 Output charging ports and yet its charging capabilities are rather mediocre.

This is the EasyAcc 15,000mAh power bank that has 3 charging ports. Let’s see if 3 is the magic number to a power.

Power Capacity

The power capacity of the EasyAcc charger is 15,000mAh.

It sounds good but the Output capacity is going to be very different for nearly everybody, this is because there are 3 charging ports and the Max Output of the power bank is 4.8A.

So if you’re charging more devices and they’re using more of the power bank’s power, then you’re going to be left with less Output capacity.

We’re gonna assume that you’re going to at least be using 2 of the 3 charging ports of the portable charger and with that, you’re going to be using about half or more than half of the Max Output. As a result, you can expect an Output power capacity of 12,000mAh.

Power Capacity for Smartphones

A 12,000mAh power capacity is still quite a lot of power that is going to be able to charge nearly any device that you use with this power bank, to charge to its full capacity. This goes for smartphones and this EasyAcc Power bank can recharge most smartphones 4 times or more.

Power Capacity for Tablets

As for tablets, they’re a slightly different case.

If you want a tablet to charge to its full capacity, then you should charge it alone or possibly with just another device connected to the power bank, preferably a smartphone.

This is because most of the power capacity of the portable charger should be attributed to the tablet. If that’s done, then this power bank will be able to charge most tablets to their full capacities like iPads.

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


The charging speed is surprisingly really good. We’re surprised because in most cases when there are many ports, the charging speed tends to wane but that’s not the case here.

Each of the 3 ports is capable of outputting 2.4 Amps, which is going to be able to charge nearly any device at its max charging speed (Except for Quick Charge compatible devices, since this power bank does not have Quick Charge).

Although it’s important to remember that the max output of the power bank is 4.8A. This means that you can connect 2 iPads and the Max Output of 4.8A will be reached since the Max charging speed of iPads is 2.4 Amps.

If you connect three iPads to the power bank, then charging speed will be limited to 1.6A for each port because the Output of 4.8A must be reached only.

It’s an ideal Max Output, even though a 7.2A Max Output would put this charger into a limitless charging speed range. There’s no need to worry about charging speed unless you are indeed charging three iPads at the same time, even then the Amperage is 1.6A.

So charging three smartphones should provide a max charging speed to the smartphones that are connected or any other devices that have similar charging speeds.

Input Charging: 5V/2.0A

If you want to recharge this power bank as fast as possible then you should use a 2 Amp wall charger. By doing so, you’ll be able to recharge this power bank within 7-8 hours. If you’re using a lower Amperage wall charger, then you’re going to be waiting double the time at 14-15 hours.

To know what the best wall chargers are to use with this power bank or any other portable chargers that you currently own; take a look at our wall charger review section.

Size and Weight:


So the power capacity matches the design for this power bank with it being not too large but being large enough and heavy enough that makes it best to just set it down and use it.

The length of the EasyAcc 15,000mAh is 5.9 inches, it has a width of 2.8 inches and a thickness of 0.8 inches. The weight is nearly a pound at 11.8 ounces.

So maybe you can carry it while you’re charging a single device but the weight of the portable charger is heavy even for its capacity.

Most of the time you’re going to opt to set the charger down, this is true for those times that you’re charging more than a single device and overall it provides a more comfortable user experience.

Functional Components:

The few functional parts of the power bank are in a few different places on the charger. The 3 USB Output charging ports are on the same short side with them all lined up horizontally next to each other.

The power button is on the long side of the charger and the Micro-USB Input port is on the opposite long side of the charger. There are 4 LED power capacity indicators on the top.


Charging automatically begins when you connect a device into any of the charging ports and charging automatically stops when there aren’t any devices connected. So this leaves the power button with mostly a single usage of simply checking the power capacity.

Structure and Material:

The structure is standard with it having a top and bottom piece. There are 2 side panels on the power bank as well.

Nearly everything on the charger is made of plastic, and with that said, it’s best not to drop this power bank.

This is because there aren’t any securities to make it preventative of taking shock damage from a fall. Along with the heavyweight, the shock on impact can be devastating.


Like most power banks or at least we hope ALL power banks.

This one has safety tech like Over-Charge protection so charging automatically stops when your devices are all fully charged, Over-Current protection so Output current is controlled and Short-Circuit is to prevent a short-circuit from happening.

If there is one flaw about the build, it’s the usage of the Lithium Polymer batteries. We realize that the use of Lithium Polymer batteries is to make the power bank more slim and portable.

However, if too much heat is generated while devices are charging then that can lead to expanding the Polymer batteries.

As a result, the body structure of the power bank can begin to expand. This can be prevalent with some power banks that are bad at managing Temperature and although it isn’t the case with this charger, it can very well be if charging is constantly taken to its limits.

However, if that happens you can always depend on EasyAcc’s 18 Month Warranty.


Reliability can go quite far. We like this power bank for its 3 charging ports and how well it goes about supporting the usage of the 3 charging ports.

The Max Output of 4.8A is what we mean by the great support for the charging ports because no matter what you’re charging or how many devices are you’re charging, the charging speed of those devices will be pretty good.

Portability can be a problem to rely on but it’s manageable if you’re just setting it down.

The Output power capacity is going to change depending on the way you use it.

However, charging smartphones multiple times is completely possible, although you’ll have to strategize a bit if you want to charge a tablet to its full capacity.

Charging speed is what makes the 3 charging ports so awesome to use, because, at nearly any charging situation, you’re going to be able to charge any device at its max charging speed. Even with the Max Output of 4.8A, the charging speed is still pretty good.


The design could better. With this power bank, the size is large and the weight is rather heavy.


Build quality is okay but the structure of the power bank is simply plastic with no reinforcements and along with the heavyweight, dropping such a charger would not bode well.


Reliability is fantastic because of the powering capabilities, with the power bank being able to charge 3 devices at once and most of the time the charging speeds of each of the devices will be really good.
