Laptops have gotten incredibly powerful, gone are the days when you would have to own a desktop computer to do heavy work like video or photo editing. In this case, I’m talking about Samsung’s most powerful laptop yet, the Galaxy Book 3 Ultra. The Book 3 Ultra can be used for just about anything, even gaming because you can choose an NVIDIA RTX 4050 or RTX 4070 model, so you’ll be able to play nearly any videogame, no matter where you are.
With all these powerful specs, this also means that this laptop uses a ton of power that can and will drain the battery of the Galaxy Book 3 pretty quickly. The good news is that the Galaxy Book 3 comes with a 100W Power Delivery charger that can keep up with recharging the laptop even when you’re using it.
If you feel limited by using a single port 100W charger with the Book 3 Ultra, I’ve chosen a few chargers you can use as a replacement that can deliver the same or nearly the same charging power. Of course, these chargers are also helpful if you’ve lost your original charger.
VOLTME 140W PD 3.1 Wall Charger
Starting with this VOLTME wall charger that features Power Delivery 3.1, you can use 140W when you charge from USB-C 1 alone. The other ports on this charger are the USB-C 2 and USB-A ports. The USB-C 2 port can output 100W if you’re charging from it alone, so you will be charging your Galaxy Book 3 Ultra from either USB-C 1 or USB-C 2. The USB-A port will always have a 22.5W charging speed, no matter how many devices you’re charging simultaneously.
Regarding charging multiple devices simultaneously, charging power changes for USB-C 1 and USB-C 2; for example, if you’re charging from each USB-C port, then each will output 65W. If you’re charging from all three ports, then USB-C 1 will output 65W, USB-C 2 will output 45W, and the USB-A port will output 22.5W. So charging power for your Galaxy Book will be rather slow when charging multiple devices.
If you want to charge your Galaxy Book Ultra at 100W and charge another device, this can be done by charging your Galaxy Book from either USB-C 1 or USB-C 2 and charging a phone or tablet from the USB-A port; this way, the USB-C 1 or USB-C 2 ports will still output 100W, this way you can fast charge your Book 3 Ultra and fast charge something like an Android phone.

UGREEN 100W USB-C 4 Port Charging Station
If you want a desktop charger that gives you a power cord and more freedom to place the charger on your desktop, consider this UGREEN 100W USB-C charging station. This charger has three USB-C ports. USB-C 1 and USB-C 2 can charge at 100W if you’re charging a single device from the charger. The USB-C 3 and USB-A port can output 22.5W.
So if you want to charge your Galax Book 3 Ultra at max speed, you must do so when charging it alone from USB-C 1 or USB-C 2. When charging two devices simultaneously, USB-C 1 or USB-C 2 can drop down to 65W, and when it comes to charging four devices simultaneously, the USB-C 1 port will be the most powerful, with an output of 45W.
The biggest reason to get this charger in the first place is because of the power cord, which makes it easier to access.

Baseus 100W GaN Power Delivery Wall Charger
If you’re searching for a true, plain replacement charger for your Galaxy Book 3 Ultra, this Baseus 100W wall charger is the one. This Baseus charger has only a single USB-C port with a 100W Power Delivery charging speed. So you don’t have to worry about other ports, the charging power dropping, or anything like that. It’s just a single port that you can rely on to fast charge your Book 3 Ultra whenever you use it, and the best part is that it uses GaN, which makes the charger incredibly small with just a length of 2 inches.

UGREEN Nexode 140W Power Delivery Wall Charger
This UGREEN Nexode 140W charger is very similar to the previous VOLTME 140W charger I recommended because this one also has two USB-C ports and a USB-A port with a 140W max output. I’m also recommending this to give you another option in case you prefer one brand over the other, but in testing for the VOLTME 140W charger and for this UGREEN 140W charger, I found them both to be excellent.
This UGREEN charger can output 140W from USB-C 1 if you’re only charging a single device; charging multiple devices simultaneously will lower charging power. So you can fast charge your Galaxy Book 3 Ultra when charging from USB-C 1 or UBS-C 2 alone. You can also charge a device from the USB-A port and still get 100W of charging power from USB-C 1 or USB-C 2.
When charging from both USB-C ports, they both will output 65W, and when charging from all three ports, the USB-C 1 port will output 65W. One great benefit of this UGREEN charger is that it comes with a USB-C to USB-C cable.

KOVOL PD 3.1 2 Port GaN 140W PD Wall Charger
If the VOLTME and the UGREEN 140W chargers are too much to keep track of because of their ports, I recommend this KOVOL 140W wall charger. This KOVOL charger has a USB-C port and a USB-A port; the USB-C port can output 140W of Power Delivery 3.1 when charging a single device. Even when charging two devices simultaneously, the USB-C port drops to 120W speed, and the USB-A port outputs 18W.
In this case, it doesn’t matter if you charge your Galaxy Book 3 Ultra alone or with another device charging from the USB-A port, as it will always charge at its max speed.

Baseus Blade 100W PD Power Bank
If you’re being portable with your Galaxy Book 3 Ultra and want a power bank to charge it with, one of the most popular on the market right now is this Baseus Blade power bank. This Baseus power bank has two USB-C ports that can output 100W power delivery. Two USB-A ports can output 30W. To get the most charging power for your Book 3 Ultra, I recommend charging it alone from one of the two USB-C ports.
One of the added benefits of getting this Baseus Blade is the screen at the top that shows the remaining capacity, voltage, amperage, and even the estimated runtime of the power bank; this much info on a screen with a power bank is not common at all, but it’s fantastic to see.

If you’re wondering about charging your Galaxy Book 3 Ultra while you’re driving, well, thankfully, there are 100W car chargers. I have reviewed this ALOGIC car charger with a USB-C port with a 100W Power Delivery output; as long as you’re charging a single device from the USB-C port, you can use the full 100W. However, there is also a USB-A port on this car charger with an 18W output, and when charging two devices simultaneously, the USB-C port drops down to a 65W charging speed.
