(Last Updated On: June 13, 2020)

One of the most notable parts of the USB-C port is how it’s able to use Power Delivery charging tech. It’s one of the main reasons why USB-C ports are now used with so many devices on the market because they are practically able to use the same PD charger to charge from. However, laptops that use USB-C ports can charge at higher charging speeds than a USB-C smartphone would be able to.

Most smartphones are only able to charge at an 18W Power Delivery charging speed, while laptops can charge at upwards of 30W. That’s why we’re here to review this Aukey PA-B5 100W Power Delivery wall charger. There are very few third-party wall chargers that can output 100W, so let’s see just what this Aukey wall charger is capable of.

Output Charging:

Alright, so the higher the charging power for a Power Delivery charger there is, the wider range of devices it’s able to charge. For example, an 18W Power Delivery wall charger is great for charging smartphones, but an 18W PD charger is not the best for charging laptops. There are many laptops on the market that are not able to charge with an 18W Power Delivery charger simply because it’s not enough power.

That’s what makes this Aukey 100W Power Delivery wall charger so valuable. Is that the 100W power output can charge your laptop, smartphone, and any other device that uses a USB-C port for charging from.

In our case, we used the Aukey wall charger to charge a Microsoft Surface Go and a Lenovo Flex 5 14” laptop. Both of the devices are Power Delivery compatible with the SUB-C ports that they have.

The Surface Go was able to charge at 30W from the Aukey charger, and we used a USB-C Multi-meter to check the charging speed. When it came to charging the Lenovo laptop we got 30W of charging when the laptop was not being used, and then we got anywhere from 40W to mid 50W of charging power for when we were using the laptop. So the laptop takes in more charging power when it’s being used, and that’s one of the main benefits of using this Aukey wall charger. It can provide power when needed, and in this case, since the Lenovo laptop uses more power when you’re using it, this Aukey PD charger can recharge more to make up for that lost power.

Even with the 100W power output, you can still charge smartphones with this wall charger, but most phones will charge at 18W only as that’s the main fast charging speed from a PD charger for smartphones. Also, just a reminder you can fast-charge iPhones with this Aukey wall charger but you have to use a Lightning to USB-C charging cable.

Size and Weight:

Even though it’s able to output 100W of charging power, this charger is tiny. It has a length and width of 2 inches and a thickness of 1.1 inches. The weight of the charger is 5.2 ounces.

Comparing this to the 65W USB-C Power Delivery charging brick that came with the Lenovo Flex 5 laptop and easy to see which one you would rather use. Not only does this Aukey wall charger output more power (100W), but it’s also more portable, and this is due to the use of a GaN chip as it’s makes the charger small while still being able to output more charging power.

Functional Components:

Even though the charger has a ton of power, it’s still as easy to use as any other wall charger. It has a retractable AC adapter, and once plugged into an AC outlet there is a White light that comes on and it’s ready to use.

Build quality of the Aukey products has always been solid and that has not changed with this 100W Power Delivery wall charger. The charger is compact, holds strong, and the AC adapter also feels sturdy to use.

Even though it has a very small form factor and can deliver 100W of charging power to your devices, it keeps cool. This is one of the key benefits of using the GaN chip as it won’t get hot under higher loads of power. Another factor for this charger is that it has a single USB-C Power Delivery port that can potentially output 100W, but most laptops don’t require that much charging power and you don’t have to worry about any other ports taking the charging power away from the device that you’re charging.


Considering that this Aukey charger can deliver 100W to charge a very wide range of devices and is pocketable, the only unreliable part of getting it would be the fact that the charger is only able to charge a single device at a time because of its use of a single USB-C port. So if you’re charging a laptop and want to charge your smartphone at the same time, you can’t.


The inclusion of a USB-C to USB-C cable would have also been nice, but if you’re getting this wall charger to charge your laptop, then it’s likely that you may already have a USB-C to UBS-C cable.



Charging power is not lacking with this Aukey PA-B5 wall charger because the single USB-C PD port can output 100W of charging power.


In comparison to other Power Delivery charging bricks that come with some laptops, this Aukey wall charger blows them out of the water because of its small size and lightweight. A charging brick with a long cord is cumbersome and dated.


The build is another strong point of this wall charger and is right up there with the charging power. This is because the charger does not overheat.


The most unreliable part is of this charger is how you’re only able to charge a single device at a time with the 100W that this Aukey charger has to offer.
