The way that we charge our devices is constantly changing and that’s because it’s something that we rely on so much.

Many people today own portable devices such as smartphones and therefore, they need a different way to charge their devices and of course, the most efficient way to charge their devices. That is why there charging technologies such as Quick Charge and Power Delivery that have been increasingly growing for many newer smartphones and also tablets.

This Jackery Titan X 20,800mAh power bank actually uses Power Delivery and Quick Charge too. The use of these two charging technologies makes this portable charger a very precise type of charger to own as it can charge two certain compatible devices at their max charging speed. So if you own Power Delivery devices or Quick Charge devices, this Jackery power bank is definitely meant for you.

With all that said, let’s get into the nitty-gritty part of things and see what this charger really has to offer.


Power Capacity:

There’s a good amount of power to be used with this power bank, but it has a low amount of power to use in comparison to other portable chargers within its class. Such as the PowerCore+ 26800 Power Delivery charger, that has a 26,800mAh power capacity, just as the name implies.

However, so long as the initial power capacity of this charger is high, then the output capacity will also be high.

3.7 x 20,800 = 76,960 / 5 = 15,392

4.4 Full Charges

Overall, you’re actually going to be receiving a capacity of 15,400mAh that you can actually use towards charging your devices. It’s with this much power that you’re able to charge most smartphones about 5 times to their full power. Or if you’re charging smartphones that have a lower capacity than 3,000mAh, this power bank will be able to serve you even beyond the 5 full charges.

Charging tablets will also hold a pretty good experience as most tablets such as the iPad or Samsung’s tablets have 6,000mAh battery capacities. Therefore you’re able to get about 2.5 full charges for them with this power bank.

Even though power banks are most known for providing power to charge smartphones, this one, in particular, is meant for more than just that, because of its use of Power Delivery with its USB-C port.

So you can charge MacBooks, a Chromebook and also the Nintendo Switch near or at their max charging speed. Also, the best part is that if you’re focusing the power bank on just a single one of those devices, then you can charge them to their full power about two times.

Which can be very useful if you’re doing work and want to be free from the restraints of an AC Outlet or if you want to keep gaming with your Switch.

Output Charging:

The Output charging is easily the best part of this power bank and that’s because it has only two USB charging ports but they’re both very powerful.

Firstly, there’s a USB-A port that features Quick Charge 3.0 and can, therefore, charge Quick Charge compatible devices that their max charging speed. You can also use this port to charge Non-Compatible Quick Charge devices and it’s able to output 3 Amps to them, which can charge them at their max power most of the time.

The second output port is the USB-C charging port, and that’s the main event of this power bank as the USB-C port features Power Delivery.

Of course, you’re going to need a USB-C to USB-C charging cable to charge USB-C compatible devices with the USB-C port. Or you can use a USB-C to Lightning cable to charge the iPhone X or iPhone 8 at their max charging speed as they’re both compatible to charge at Power Delivery speeds.

With the use of Power Delivery, you’re able to charge devices such as the new MacBook models at their max charging speed, and you can also charge USB-C compatible Chromebooks at their max power too. The main reasons for that are because the Power Delivery is able to output 45W of power, which is basically equivalent to the same power output that most USB-C wall chargers that come with MacBooks have.

Input Charging:

Recharging with this power bank is also very fast and that’s because you’re able to recharge this power bank through its USB-C port with Power Delivery speeds. That said, you need a Power Delivery wall charger and the best part is that this Jackery Titan X power bank actually comes with a 1-port 45W USB wall charger.

So to recharge this power bank as its max power, you just need to use the wall charger that comes with it and also use a USB-C to USB-C charging cable. With the use of its included 45W USB-C wall charger, you’re able to recharge this 20,800mAh power bank to full power in about 3 hours only.


Size and Weight:

Even though most power banks with high power capacities have rather small sizes or at least manageable ones that can indeed be taken anywhere. This Jackery Titan X 20,800mAh PD power bank has a rather large size and that is mostly due to the Power Delivery tech that is put into this portable charger.

As a result, it has a length of 8.2 inches, a width of 4.4 inches, and a thickness of 2.5 inches. The weight of this charger is 1.9 pounds. So it’s definitely on the heavy side and therefore, you’re not going to want to hold this charger while you charge a device for a smartphone as you’ll likely get tired of holding it.

This power bank is a lot better utilized when you place it down and charge your devices. One main reason being its size and weight, and the other one being the fact that this power bank can charge large devices such as laptops.

Functional Components:

This is a very minimalistic design from Jackery and that is a good thing. As all of the functional parts are on a single side.

It’s on this single side is where you’ll find the power button, a digital power capacity indicator, the USB-C Power Delivery port and also the Quick Charge USB-A port. To begin charging through either of the two ports, you must press the power button.

The digital display automatically shuts off after the power bank charges for a few seconds and to check the power capacity you can just press the power button once.


Structure and Material:

Most of the power bank is made of Aluminum Alloy and by most, I mean that the center of this charger is made of the Aluminum construction and that is a very large part of it. The sides of the charger are made of plastic.

Not only are the materials very good to use, but also, this charger has a great build quality when it comes to the USB charging ports with the way that the cables feel and also with the way the power capacity indicator works.


On the tech side, this power banks keeps things rather cool and that is a very good thing. As it’s capable of 45W of power and that can tend to heat most portable and wall chargers up quite a bit.


This Jackery Titan X power bank is definitely not for everyone and that is something that you should realize. If you don’t own a device that requires Power Delivery charging, then getting this power bank is probably a waste of money, even if you do own a Quick Charge compatible device, it simply doesn’t make any sense without the use of Power Delivery.

That said, if you do have use of its Power Delivery capabilities then this power bank is a very valuable purchase and you should absolutely consider getting this charger. As it can charge USB-C compatible devices near or at their max power, it has a Quick Charge port, and the power bank even comes with a Power Delivery USB-C wall charger.

The addition of a USB-C wall charger is very useful to recharge this power bank at its max charging speed and also for charging your USB-C compatible devices at their max power while you’re stationary.



There’s a good amount of power capacity to be used with this power bank as it can charge smartphones many times over. At the same time, larger devices can charge a few times to full power too. Its use of Power Delivery is its main point and it can be useful for charging lots of devices at their max power if they’re compatible with PD.


It has a design scheme with basically all of its functional components being on a single side, making it easy to use.


The build quality of this charger is very good as nearly the whole power bank is made of Aluminum Alloy.


It’s best to get this Jackery Titan X power bank if you’re actually going to rely on the Power Delivery capabilities of this charger.
