High capacity power banks aren’t thought to be the most useful types of portable chargers on the market and that’s because they have a larger size and a heavier weight than lower capacity power banks. However, that’s really the only difference between low and high capacity chargers. Overall, high capacity power banks are the more useful type of charger that you can purchase and that’s because, well for one, they have more power capacity that you can use and they also have more charging ports and some of them use fast charging tech.

This Aukey 20,000mAh power bank with Quick Charge and USB-C just goes to show that a high capacity power bank can actually be a better option than mini ones. Also the charger, despite its higher power capacity has quite a small size that you can still take anywhere that you want.

Power

Power Capacity:

This Aukey power bank has a base level high power capacity and what that means is that it has a 20,000mAh capacity. This is a lot of power to use for a portable charger, but at the same time, since there are quite a lot of power banks on the market that have2 higher power capacities, this is on the low side when it comes to the high power capacity segment.

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

Just like all high capacity power banks after their conversion, this charger still has a good amount of power left to use. The average output capacity that you’re able to use is about 15,000mAh and this is great for charging smartphones, as most smartphones these days have a 3,000mAh battery and you can, therefore, get about five full charges if you’re solely charging a smartphone from this power bank. At the same time, since this power bank does feature Quick Charge and you’re likely going to be charging a Quick Charge compatible smartphone with it, then that can result in a lower output capacity of about 13,000mAh.

Charging tablet to full power multiple times with this power bank is also possible but if you want more full charges then we recommend charging a tablet alone with this power bank. Even charging a USB-C compatible MacBook with this power bank is also possible because of its usage of a USB-C port, however, the USB-C port on this charger does NOT feature Power Delivery and won’t charge a MacBook at its max charging rate.

Output Charging:

There are a total of three ways to charge from this Aukey 20,000mAh power bank. It has a USB-C port that can be used as an output and there are two USB-A ports.

One of the USB-A ports features Quick Charge 3.0 and so you can fast charge Quick Charge compatible smartphones at their max charging speed, The other port is a standard one that has a standard fast charging speed of 5V/2.4A.

The USB-C port on this Aukey power bank has a 5V/3.0A (15W) charging speed and you can use a USB-C to USB-C charging cable to charge USB-C compatible smartphones, tablets and few laptops with it. The USB-C port on this power bank does not feature Power Delivery so it won’t charge USB-C compatible laptops at their max charging speed and it might not charge most USB-C laptops, to begin with, because of its lack of Power Delivery.

Input Charging:

There are surprisingly two ways to recharge this power banks and we’re “surprised” simply because Aukey could have just made the USB-C port the only input and called it a day. That said, the USB-C port is one of the input ports and it has a 5V/2.0A recharge rate. While the USB-C port being used as an input has a 5V/3.0A recharge rate.

Design

Size and Weight:

The size of this power bank is one of the best parts of it, right next to the powering capabilities that it has. The charger has a length of 5.9 inches, a width of 2.8 inches, and it has a thickness of 0.9 inches. The weight of the charger is 13.3 Ounces. So the charger is actually not very large and the only thing that makes it seems quite large is the weight of it.

You can place this power bank into your pocket but you’re not going to want it there for long, and most of the time you’re going to be setting this power bank down if you’re charging multiple devices at once.

Functional Components:

All of the functional parts of this charger are in the same general location that can be found on one single end of the power bank.

The two USB-A ports and USB-C port are on a single side, the Micro-USB input is alone on a single side and the power button is on the opposite side. At the top of the power bank is where there are four White LED power capacity indicators.

You do have to press the power button to begin charging from any of the charging ports.

Build

Structure and Material:

The build quality of this Aukey power bank feels absolutely solid and this is something that you can expect from most of Aukey’s products, to begin with. The top has an etched design and the siding feels well-placed. Also, using the charging ports feel quite premium because the charging cables hold very well in the charging ports.

Tech:

On the tech side, this power bank does get a little warm if you’re charging multiple devices at once, and by multiple devices, we mean that if you’re maxing out the charger by charging three devices at once. Charging two devices at once or charging a Quick Charge compatible smartphone with this power bank does not make it warm.

Reliability

With its many charging ports, high power capacity and two input ports, this charger can be reliable for anyone that’s looking to charge their USB chargeable devices. That said, because of it’s use of Quick Charge and it having a USB-C and Micro-USB input port, this is most reliable for those that own a Quick Charge compatible Android smartphone.

Summary:

Power:

There’s a good amount of power capacity to be used that can charge smartphones to their full power multiple times over. The use of many charging ports is also very useful especially for those that own Quick Charge compatible smartphones.

Design:

Even though it has a high power capacity this Aukey power bank still has a small size in comparison to most other 20,000mAh power banks.

Build:

The charger only gets a little warm if you’re charging 3 devices at once.

Reliability:

On the reliability scale, it’s most reliable for those that own a Micro-USB or USB-C Quick Charge compatible Andriod smartphone. It’s useful if you have an iPhone or other Apple products such as a tablet but you won’t be able to use the Quick Charge port.
