  • 18W of Power Delivery, so it's really meant for charging smartphones
(Last Updated On: September 17, 2019)


Most Power Delivery portable chargers on the market usually have high capacities, such as Anker’s PowerCore+ 26800 portable charger, or Jackery’s SuperCharge 26800 power bank.

Those types of power banks not only have lots of power capacity but they also have some high Power Delivery charging. With the PowerCore+ featuring a 30W charging speed. While the Jackery SuperCharge features a higher 45W of charging power.

Since they have high capacities, and faster Power Delivery charging, this makes the price of those power banks higher.

This Aukey 20,000mAh power bank is different though. It still has a high capacity, although not as high as the first two power banks that we mentioned.

It also has a lower Power Delivery charging speed. Putting those two things together, what you’re left with is a lower priced high capacity Power Delivery power bank that you may want to consider getting if you’re not too concerned about 30W of Power Delivery or higher.


Power Capacity:

The power capacity of this power bank is 20,000mAh and plenty of power for charging small devices such as smartphones and larger devices like tablets.

First though, let’s see how much of this capacity you’re actually able to use.

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

So the actual amount of power that you’re able to use is about 15,000mAh from this power bank.

It’s still a good amount of charging tablets and even some laptops, as this power bank does feature Power Delivery.

Perhaps the most useful way to charge from this power bank is going to be smartphones, though. As you’re able to charge them to full power multiple times over.

The one other reason this power bank is great for charging smartphones is because of the ports.

Output Charging:

There are two output ports to charge from.

One is a USB-A port that features Quick Charge 3.0 that can fast charge Quick Charge compatible smartphones.

The other port is a USB-C Power Delivery port with a 18W charging speed.

Power Delivery made for Smartphones

Galaxy S8 Fast Charging with the USB-C Power Delivery port alone.

So this power bank does not feature a 30W or 45W charging speed as some high-end Power Delivery power banks do. That’s okay.

The reason for that is because this Aukey Power Delivery power bank is perfect for charging Power Delivery compatible smartphones. As 18W of charging power can fast charge smartphones like the iPhone X, iPhone XS, Google Pixel and other PD smartphones.

Galaxy S8 Fast Charging with the Quick Charge port alone.

You would, of course, need a USB-C to USB-C charging cable to charge USB-C smartphones or a USB-C to Lightning cable to charge iPhones.

You can also charge USB-C Power Delivery laptops with this power bank, but the one that you can surely charge with it would be a USB-C MacBook.

As many Power Delivery laptops require more than just 18W of charging power.

Galaxy S8 and Google Pixel charging at the same time. The Google Pixel is Rapidly charging using the Power Delivery port, while the Galaxy S8 is standard charging using the Quick Charge port.

Input Charging:


To recharge this power bank you can use two ports.

One is, of course, the USB-C Power Delivery port and the other is a Lightning port.

Yes, this power bank actually features a Lightning port, so this power bank is certainly being aimed at iPhone users, as well as USB-C smartphones users, too.

That said, the USB-C port to recharge this power bank is better as it has an 18W recharging speed. So you should use a USB-C Power Delivery wall charger to recharge it at its max charging speed.


Size and Weight:

High capacity power banks are of course going to be larger and heavier than ones that have lower capacities.

That said, this power bank isn’t too large and you’re going to be able to take this power bank anywhere that you would take a 10,000mAh power bank with you.

It has a length of 6.9 inches, a width of 2.7 inches, and a thickness of 0.9 inches. The weight of the power bank is 13.4 Ounces.

So you can easily just place thins power bank into a pocket because it’s still rather slim.

Functional Components:

Nearly all the functional parts of this power bank are on a single side. With all the charging ports and four Green LED power capacity indicators being on one side.

While on the long length side is where you’ll find the power button.


Structure and Material:

The build quality of this power bank is great even though it’s not made of Aluminum, but it doesn’t have to be.

The entire power bank is made of plastic, but it’s still absolutely solid. Another reason that the use of plastic is okay is that the charger has a lower price because of it.


On the tech side, this power bank does not get warm even if you’re charging two devices at once with it.


This is a reliable power bank if you have a Power Delivery compatible USB-C smartphone or a Power Delivery smartphone.

It’s also reliable if you have a Quick Charge Android smartphone.

If you don’t own a fast charging compatible smartphone that can either use Power Delivery or Quick Charge, then it’s best to pass on this power bank and get a standard one.

Also, it’s not reliable for charging Power Delivery USB-C laptops, as the 18W of charging power may not be enough.



The power capacity can charge smartphones to full power multiple times over. Fast charging includes Quick Charge and 18W of Power Delivery charging that’s perfect for smartphones.


The power bank may be long but it’s slim and therefore as easy to carry around as a 10,000mAh power bank.


The build quality of this power bank is pretty good with its structure and the use of plastic is done well.


This is a very reliable high capacity power bank to use for Power Delivery or Quick Charge compatible smartphones.
