Laptops have become remarkably powerful, eliminating the need for a desktop for intensive tasks like video or photo editing. A prime example is Samsung’s Galaxy Book 3 Ultra, their most potent laptop to date. This laptop is versatile enough for almost any task, including gaming, thanks to options for NVIDIA RTX 4050 or RTX 4070 graphics, allowing you to play a wide range of video games anywhere.
However, the high-performance specifications of the Galaxy Book 3 Ultra mean it consumes a lot of power, leading to rapid battery drainage. The good news is that it comes with a 100W Power Delivery charger, capable of efficiently recharging the laptop even during heavy use.
If you’re looking for more flexibility than the single-port 100W charger provides, or if you’ve misplaced the original charger, I’ve selected several alternative chargers. These chargers offer the same or similar charging power, making them suitable replacements for the Galaxy Book 3 Ultra. Let’s explore these options.
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 that 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 charge simultaneously.
Regarding charging multiple devices simultaneously, charging power changes for USB-C 1 and USB-C 2; for example, charging from each USB-C port will output 65W. If you’re charging from all three ports, 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 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. Learn more about the UGREEN 100W USB-C 4 Port Charging Station by reading my review article or watching my video.
Baseus 100W GaN Power Delivery Wall Charger
If you’re searching for a true, plain replacement Galaxy Book 3 Ultra charger, 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 else. 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. Find out the details of the Baseus 100W GaN Power Delivery Wall Charger in my review article.
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 only charge 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 will both output 65W; 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. Check out my review article or video for insights on the UGREEN Nexode 140W Power Delivery Wall Charger.
KOVOL PD 3.1 2 Port GaN 140W PD Wall Charger
If the VOLTME and the UGREEN 140W chargers are too much to track because of their ports, I recommend this KOVOL 140W wall charger. This KOVOL charger has a USB-C port and a USB-A port, which 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 maximum speed. Explore the features of the KOVOL PD 3.1 2 Port GaN 140W PD Wall Charger in my detailed review article.
Baseus Blade 100W PD Power Bank
If you’re 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.

I have reviewed this ALOGIC car charger with a USB-C port with a 100W Power Delivery output; if you’re charging a single device from the USB-C port, you can use the total 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.
