Aukey’s 20,000mAh Portable Charger with Quick Charge is almost magical

AUKEY 20kmAh-1

Portable chargers are great. They can really save the day when you’re on the go and your device’s battery is low. I can’t get enough of them. But one of the biggest annoyances I have with portable battery packs it that they need charging, too. It’s one more thing you need to plug in at night, and if you forget to plug the portable charger in and it’s spent, it’s worthless.

I’ve had the opportunity to review the Aukey 20,000mAh Portable Charger with Quick Charge (QC) 2.0 over the last couple of weeks and it does not solve my annoyance with having another thing to charge overnight. However, the giant 20,000mAh battery capacity gets pretty close. I can go days without recharging this thing and get all the battery boosts I need to get through those days. It’s fantastic.

Aukey’s portable charger has its quirks, but it’s managed to become one of my favorite battery packs for its combination of capacity, features, and price.

The design

This Aukey 20,000mAh Portable Charger has a very simple design, which I appreciate because I don’t feel the need to have wild colors or fancy shapes on my power banks. This is a matte black brick with ‘AUKEY’ debossed on the top.

There’s also a single button with many typical battery functions, such as displaying the current battery charge range, starting the charging, and if held down, the flashlight will turn on. An LED light behind the button will indicate that the Portable Charger is charging, and on the front, there are two standard USB ports: one green that uses a 5V 2.4A AiPower technology to automatically adjust the power output for your device’s needs. The second standard USB port is colored orange and is the Quick Charge 2.0 port.

If you’re not familiar with Quick Charge, it’s a Qualcomm technology supported by many newer mobile devices that allows for rapid charging. If your device doesn’t have QC capability, the second USB port will just act like a regular charging port with normal charging speeds.

In-between the two USB ports is the LED flashlight, which is handy for emergency purposes. Lastly, there’s a Lightning port and a micro-USB port for charging the pack. A QC 2.0 wall charger will recharge this Aukey pack faster than a standard wall adapter.

I only have one complaint about the Aukey 20,000mAh Portable Charger: When you press the button to see how much of a charge the pack has, the colors are in a silly order. Red means 0-30 percent, green means 30-70 percent, and white means 70-100 percent charged. I used the pack for a few days thinking I wasn’t able to get it fully charged until I busted out the manual to make sure I wasn’t doing something wrong, and my suspicions were confirmed: green does not mean fully charged, white does. I’ve talked to several people and they also thought green should mean fully charged. This isn’t a big deal if you know what’s going on, but it’s a weird choice, Aukey.

The data

AukeyDataAs you can see in the graph to the right, I did some simple charging speed tests with the Aukey 20,000mAh Portable Charger, comparing its two charging points with the Choetech QC 2.0 portable charger reviewed here. I used Battery Widget Reborn to export the data. In the graph, I’ve included the charging rates for the different charging methods.

The Choetech pack charged my Nexus 6 the fastest, using its Quick Charge 2.0 port to charge at a rate of about 1.33 percent per minute. The Aukey QC 2.0 port was a close second, posting a charge rate of 1.16 percent per minute.

As a disclaimer, I wasn’t able to start them both off at the exact same battery charge. I’m not sure how this effects the results knowing that the QC technology charges very quickly in the early stages of a charging session and then will slow down in the later stages. Regardless, these rates would result in a difference of minutes to get a complete charge.

Last, the Aukey’s non-QC 2.4A port was also tested, posting in a charge rate of 0.6 percent per minute, almost half the speed of the QC ports.

In conclusion, if your device has QC technology, it’s well worth it to get chargers that can take advantage of the technology’s increased charging rates.. In the end of this head to head battle, though, the Choetech charger narrowly beat out the Aukey charger.

The verdict

One last topic that needs to be brought up is this portable charger’s price. Aukey is currently selling its 20,000mAh Portable Charger with QC 2.0 on Amazon for $34.99 with Prime shipping. Also available is a nearly identical pack for $29.99 that swaps the QC outlet for another 2.4 Amp outlet, which would be the obvious choice if you don’t have a QC device. There’s a $39.99 portable charger with QC 3.0, too.

The QC 2.0 portable charger that I reviewed is very competitively priced compared to similar devices on Amazon. Aukey is a fairly well-known name, and all of their products come with a 24-month warranty.

So what’s the verdict? I think Aukey’s 20,000mAh Portable Charger a great piece of kit at a great price. We have a couple of Quick Charge 2.0 devices, and so this battery pack will quickly charge our phones, and so it’s become my go-to portable charger. I highly recommend it.

Let me know if you have any questions regarding the Aukey 20,000mAh Portable Charger with Quick Charge 2.o. Additionally, if you have a favorite battery pack or something else that you’d like to share, please get involved and let us know your thoughts.
