Using the latest type of tech when it comes to power banks is a must because people want to be able to charge their device with the latest type of charging tech while they’re out and about.

Power Capacity:

The power capacity of this power bank is quite high at 16,750mAh and the conversion rate of the power capacity can change depending on what you’re charging and whether you’re using a single USB port or two USB ports at the same time.

The reason for that is because this portable charger has amazing charging capabilities with the use of Quick Charge, Smart Charge with each port having a 5V/3.0A Output and the Max Output of the power bank is 6 Amps.

With that said, we’re going to calculate the average conversion rate that you will most likely get without using its Quick Charge abilities.

Most of the time you’re going to be receiving an Output power capacity of 12,400mAh and this power capacity is still highly useful when it comes to charging smartphones.

Since you’re able to charge high capacity smartphones like the Google Pixel XL or the Galaxy S8 to their full about 4 times. Charging low capacity smartphones such as an iPhone SE or an iPhone 7 can result in 6 full charges or even more than that.

This power bank is going to be perfect for charging smartphones with its power capacity and also because there are quite a lot of smartphones that are compatible with Quick Charge which the power bank has.

Power Capacity for Tablets

The power capacity is “Okay” for tablets, but it’s important to realize that you charge a tablet once with this power bank, then it’ll take a good chunk of power capacity away.

Charging an iPad Mini 2 or an iPad Mini 4 once to their full power will still leave the power bank with enough power to charge smartphones a few times to full power. However, charging a tablet multiple times, such as 2 times, will fully deplete the power capacity that it has.

Output Charging:

The Output charging of this EasyAcc MegaCharge power bank is phenomenal.

There are two USB ports and each of the USB ports uses EasyAcc’s Smart Charge tech which means that they’re both able to charge at a 5V/3.0A charging speeds.

The normal max charging speeds for most power banks at this level is 5V/2.4A but this power bank goes a bit further than that and goes into the 3 Amp range. We see this kind of innovation not only with this power bank but also with Anker’s PowerCore II power bank and also their PowerCore 26800.

In addition to each port having a 5V/3.0A Output, the Green USB port also has Quick Charge which has charging speeds of 5-6V / 3A, 6-9V / 2A, 9-12V / 1.5A when you’re charging a Quick Charge compatible smartphone and so it can charge at its max charging speed.

The best part of the Output with this power bank is that it has a 6 Amp Max Output and that means you use can use the max capabilities of the USB Ports at the same time.

Input Charging:

The Input charging is just as impressive as the Output charging of the power bank and that’s because there are two input ports. Of course, EasyAcc using two Input ports is something as they’ve already done with their Monster 26,000mAh power bank. In this case, though, they’ve just done a better job.

The Input ports that are used are a Micro-USB and Type-C Input port. The Type-C Input has a 5V/3.0A recharge speed and the Mirco-USB Input has a 5V/2.0A recharge speed.

You can use them both at the same time and that will result in a 5 Amp Input recharging speed for the power bank. Recharging this EasyAcc 16,750mAh power bank will result in a 3.5 hour Full recharge time which is one of the fastest on the market.

With all that said, to make sure that you recharge the power bank at its max charging speed, it’s best to use a Quick Charge USB wall charger.

Size and Weight:

The MegaCharge power bank is not very large nor is it very heavy. It can practically be taken anywhere and that is good news for such a strong power bank.

It has a length of 5.3 inches, a width of 3 inches, and a thickness of 0.9 inches. The weight of the charger is 10.9 ounces.

Functional Components:

It’s a simply designed power bank, just as all power banks should be.

On top of the power bank is where there are 4 White LED power capacity indicators. Charging does start automatically and that leaves the power button with the main function of simply checking the power capacity.


Structure and Material:

The entirety of the power bank is made of plastic and this is the case with most of EasyAcc’s power banks and it’s not a bad thing. It still has a solid build and makes the power bank lighter than if it were to use Aluminum.


On the tech side, the power bank has lots of high-quality components that make it great to use with it not heating up even when you’re using its Quick Charging capabilities. However, the power bank does heat a little when it’s being recharged using both of its Input ports, which can be expected with its 5 Amp Input.


The reliability of this power bank is perfect because it provides an optimal standard charging speed of 5V/3.0A and it can also charge Quick Charge compatible smartphones at their max charging speeds.

Its most reliable feature is its recharge as you can re-use the power bank within a matter of 3.5 hours and it’s ready at full recharge.

One of the most reliable power banks on the market because it uses a fast charging tech called Quick Charge, has a 3 Amp standard charging speed, and a fast recharging speed too.
