High capacity power banks are the more useful types of portable chargers on the market. Not only do they have more power for charging your devices multiple times, but they also make use of more charging ports.

As a result, letting you charge multiples devices at the same time. In this review, we’re going to be taking a look at EasyAcc’s 20,000mAh power bank that features four ports and actually makes use of two input ports.


Power Capacity:

The power capacity of this EasyAcc power bank starts at 20,000mAh, but let’s see how much of it you’re really able to use.

3.7 x 20,000 = 74,000 / 5 = 14,800

So you’re left with about 15,000mAh of output capacity that you can actually use with this power bank. This is a good amount of power to have, considering that this charger features four ports. Therefore you can charge four devices at the same time.

That said, with its use of four ports, and the ability to charge multiples devices at once, the more devices you charge at the same time, the faster the power capacity will burn out. It’s just something to think about.

Of course, you do have the ability to make sure that you don’t lose as much power by charging one or two devices at a time. Doing so will allow you to get about four full charges for smartphones and tablets can fair about one or two full charges.

Output Charging:

One of the best parts of this power bank is the ability to charge four devices at once. There are quite a lot high capacity power banks on the market, but most make use of two ports.

However, we do have to point out the negatives with this power bank first. The main things are that the power bank does not feature Quick Charge with any of its ports. Neither is their Power Delivery used with this power bank.

The EasyAcc power bank powering two wireless chargers, recharging another power bank and charging a Galaxy S6. All at the same time.

Onto the charging power from the ports, the power bank makes use of a 4.8A max output charging rate. With each port being able to output a 5V/2.4A charging speed. So you can use two ports at their full power, at the same time.

However, if you’re charging four devices at once, then the max output of 4.8A will likely be split between the ports. That said, we think that it’s a sacrifice to be made to be able to charge four while you’re on the go, and not having to be stationed in a single place.

Input Charging:

Recharging this power bank is also another highlight part of this charger. That’s because the power bank makes use of two Micro-USB input ports that can be used at the same time.

Each of the two input ports has a 5V/2.0A recharge rate, and when used at the same time, you can recharge the power bank at a 4A recharging speed.

EasyAcc mentions that the power bank can be recharged to full power within 6 hours. It can be done faster than that when using the two input ports and it will come to about 5 hours.


Size and Weight:

With its high power capacity, the use of four output ports, and two input ports, all contribute to the size. You’re still going to be able to take this charger anywhere you want, heck, you can even fit it into a pocket if you’re wearing pants that have large enough pockets.

But it is quite large and weighs more than low capacity power banks, just as you would expect.

The charger has a length of 6.5 inches, a width of 3.1 inches, and a thickness of 0.8 inches. The weight of the power bank is 16 ounces, so it actually weighs one pound.

You can charge and move with this power bank, but if you’re charging multiple devices at once, then you’re going to have set the power bank down.

Functional Components:

When it comes to using the power bank, all four output ports can be found on the same side, along with a LED flashlight.

Double Tap the Power Button to turn on the LED Flashlight.

Yes, even with everything else, they still managed to fit a flashlight onto this power bank. Then on one side, there’s a power button and on the opposite side, you’ll find the two Micro-USB input ports.

On top of the power bank is where there are four LED power indicators.

Once you plug a device into one of the charging ports, you do have to press the power button to begin charging, as charging does not automatically start.

Also, to turn on the flashlight, you have double tap to the power button and do the same to turn it off.


Structure and Material:

The entire charger is made plastic, but it still has a solid build. There are no loose parts, and the charging ports hold on strongly to the cables that you place into them.


On the tech side, the charger does get a little warm if you’re charging four devices at once for a long duration of time. However, it does not get warm if you’re using the two input ports at the same time.


On the reliability scale, this power bank can be considered to be universally reliable as long as you’re not expecting any fast charging tech such as Power Delivery or Quick Charge, as it doesn’t feature those.

However, charging four devices at once can be highly reliable if those around you also want to charge their smartphones at the same time. The high capacity doesn’t get in the way of the recharge time either, as the power bank makes use of two input ports.



The power bank has enough power capacity to charge smartphones to full power multiple times. The usage of four ports is helpful for charging multiple devices at once, and you can recharge the power bank quite quickly with its use of two input ports.

The only downside is that the charger does not feature Quick Charge or Power Delivery charging.


The charger is quite large, and even weighs one pound. Don’t let that mislead you though, as the power bank is still very portable and can be taken anywhere that you want.


The power bank has a solid build and that actually feels quite premium to use, regardless of it being made of plastic.


It’s a great power bank if you want lots of power and the ability to charge multiple devices at the same time. Not too reliable if you have a Power Delivery or Quick Charge compatible smartphone and want to fast charge your phone, as it doesn’t feature either of those fast charging technologies.
