Review: Anker PowerCore Speed 20000 PD Portable Charger

Anker PowerCore Speed 20000 PD Portable Charger









  • Very High Capacity that can last for days or even weeks
  • Fast charging through the USB Port and the Type-C Port
  • It's actually quite small


  • Nearly a Pound at 12 ounces, so it can be heavy
  • Makes sense to purchase if you're using the Type-C port as a Output port
(Last Updated On: September 14, 2020)

Power Delivery charging is becoming more common for many portable devices such as smartphones, tablets, and laptops. The reason for that is because it’s able to supply lots of power, and therefore you’re able to charge a wide range of devices with the same charger such as your phone and a laptop, as that’s mainly the goal of PD charging.

In this review, we’re going to be taking a look at Anker’s PowerCore Speed 20000 PD portable charger. Whether you’re new to our site or have been here before, then you need to know that Anker is a brand that creates top-quality portable chargers. This PowerCroe Speed 20000 charger is definitely on the innovative side with its capacity, charging power, and form factor, too.

Power Capacity:

So despite the name of the charger, this Anker power bank has a 20,100mAh power capacity. Just like all power banks on the market, the listed power capacity of a portable charger is not the one that you’re able to use the entirety of. There’s a conversion of power during charging and so some power is lost. Since Anker doesn’t provide the Voltage for the battery that they use, most batteries with power banks are 3.7V.

3.7 x 20,100 = 74,370 / 5 = 14,874

When it comes to the output capacity, which is the power capacity that you’re able to use, this charger will be able to supply about 15,000mAh. With this much power, there’s still a lot to do.

Power Capacity for Small Devices

With 15,000mAh, you’re able to charge most smartphones on the market to their full power about three to four times. Just a reminder that most phones these days have quite a large battery with the growing power usage of them, and so the use of the 3,000mAh to 4,000mAh batteries is more common. For example, the Galaxy Note 10+ has a 4,300mAh battery, while the Samsung Galaxy S10+ has a 4,100mAh battery.

Even the iPhone now has a large battery for iPhone standards, with the iPhone XS Max using a 3,174mAh battery. Using an iPhone to charge with this power bank can deem useful, and we’ll get to that later in the Output Charging section.

Enough Power for Larger Devices, Too

As for charging larger devices such as tablets and laptops, this PowerCore 20000 PD power bank fairs wells, too. Of course, when it comes to charging these larger devices you’re going to get one full charge at least, with a little power left over.

Most MacBook batteries have a 6,000mAh battery capacity, and since this power bank does feature Power Delivery you’re able to charge a MacBook with it. With a 6,000mAh power capacity you can charge most USB-C MacBooks to full power at least once, and with quite a bit of power left over. It mostly depends on whether you’re still using your laptop or tablet at the same time while it’s charging.

Output Charging:

There are two output ports on this power bank. One is the USB-C Power Delivery port, which is the focal part of this Anker power bank. The other is a USB-A port with standard charging.

The USB-C Power Delivery port on this PowerCore Speed 20000 PD has a 30W charging speed. This goes beyond the regular charging speed for Power Delivery charging on most power banks, as many power banks have an 18W PD charging speed with their USB-C ports.

This is where Power Delivery charging excels, as higher charging power of PD can charge a wider range of USB-C PD compatible devices. In this case, it would be smartphones, tablets, and laptops, too.

Fast Charging Smartphones with PD

When it comes to fast charging smartphones, you’re able to charge fast charge most Android phone with the USB-C port on this power bank as the needed PD charging rate is 18W. In the above image, we’ve got a Galaxy S8 and a Google Pixel charging at the same time. The S8 is fast charging using the PD port, and somehow, the Pixel is fast charging using the standard USB-A port that has a 10W charging speed.

Charging Larger Devices with the PD Port

As for charging PD tablets, and laptops, this PowerCore Speed was practically made to do that. With 30W of charging power, you’re able to fast Apple’s USB-C MacBook, and also their iPad Air that now uses a USB-C port.

This PowerCore Speed 20000 will also be able to charge most Chromebooks on the market that use a USB-C port to charge from, too.

That said, just because you’ve got a USB-C Power Delivery laptop does not mean that this power bank will be able to charge it. As some devices require more charging power than 30W and won’t charge unless you have a higher PD charging power.

Also, you can fast-charge an iPhone from the iPhone X, and iPhone 8 and onwards, as these newer model iPhones are now Power Delivery compatible. That said, just remember that you’ll need a Lightning to USB-C charging cable.

Input Charging:

One of the best parts of Power Delivery power banks is that you’re almost always able to use the USB-C PD port to recharge from, and that means you’re able to recharge the power bank at PD speeds.

In this case, you’re able to recharge from the PD port, and the better part is that the PowerCore Speed 20000 PD comes with a 30W Power Delivery wall charger. As a result, you’re able to recharge the power bank at its full power right out of the box.


Size and Weight:

Even with all of its charging power, Anker almost always manages to have a small form factor with its power banks. This charger has a length of 6.5 inches, a width of 2.4 inches, and a thickness of 0.9 inches. The weight of the charger is 13 ounces.

So the power bank is quite long, and a bit heavy, we found that we could easily just place it into a pocket and forget about it. Of course, that would get tiresome after a while, but remember that you’re carrying around 20,000mAh of power with 30W of PD charging in your pocket. Placing it into a backpack or a purse is also a great option, too.

Functional Components:

The functional parts of this power bank are centered very close to each other. The two ports are next to each other, there are four Blue LED power indicators at the top, and the power button is on the long side.

Charging automatically starts when you plug a device into the power bank, and so the power button is only useful for checking how much power is left.

Structure and Material:

If you’ve ever owned an Anker product then you know that it’s a brand that takes quality seriously and that’s no different here. The PowerCore Speed 20000 PD isn’t using any special material as it’s all made of plastic. However, it’s well built and solid, there are no loose parts, the ports hold on tight to the charging cables that you input to them, and the power button feels super responsive.

It’s by no means a rugged power bank, so be careful about dropping it, but for every day use it’s a beast.


When it comes to PD charging or any fast charging tech, heat is a major concern. The great thing is that even while fast charging the Galaxy S8 for about 30 minutes with this power bank, the power bank did not heat up at all.

However, the S8 did warm up a little.


This Anker PowerCore Speed 20000 PD power bank is a portable charger about purpose and power. Its purpose is to be used for its 30W of Power Delivery charging. It’s going to be reliable to use to fast charge your smartphone, but its purpose is fully used when you use it to charge a USB-C PD laptop like a MacBook.



There’s quite a lot of power capacity to use to charge small and larger devices to full power multiple times, or only once. The PD charging is the highlight of this power bank as it’s able to supply 30W of charging power and it’s also able to be recharged at PD speeds.


The charger has a smaller form factor than you realize, and you’re able to fit it into a pocket without much trouble.


The build is not rugged, but solid, and feels great to use for everyday use with its tactile feel.


The reliability of this power bank is higher for those that make use of its PD charging further than just smartphones.

  1. Whilst it is quite pricey, I like the fact that it can charge my macbook as its much easier to carry around than the normal macbook cable and it means that I can be away from plugs, knowing that I can charge it.
    I would have liked a quick charge plug to be included in the box as I have no way to charge it other than using other powerbanks.
