AI Verdict
A dual USB-C 45W GaN power adapter with PPS support, designed for charging phones and small personal computers.
This 45W GaN charger is a situational fit because its dual USB-C ports and 45W maximum output are useful for specific charging needs, like a phone and a tablet, or a low-power laptop. However, the shared wattage and the secondary 15W port mean it won't be a powerhouse for two high-demand devices. Its compact size and safety features are strong points for portability.
If you need to fast charge two devices at higher wattages concurrently, look for a charger with a higher total wattage (e.g., 65W or 100W) and explicit per-port wattage distribution.

Pros
- GaN technology allows for a compact and portable form factor, making it travel-friendly.
- Features two USB-C ports, with one delivering up to 45W and a secondary port providing 15W (5V/3A).
- Supports Power Delivery (PD) and PPS fast charging profiles, including 5V/3A, 9V/3A, 12V/3A, 15V/3A, and 20V/2.25A (45W Max).
- Includes comprehensive protection functions: over-power, over-current, short-circuit, over-voltage, low-voltage, and electrostatic protection.
- UL Listed, indicating compliance with safety standards.
Cons
- The 45W maximum output is shared between the two USB-C ports, potentially limiting simultaneous fast charging for two high-power devices.
- The secondary USB-C port is limited to 15W (5V/3A), which is slower for many modern devices.
- 45W may not be sufficient for fast charging some larger laptops that require 60W or more.
- No user feedback is available to assess real-world performance or durability due to a future release date.
Dimension Scores
The charger provides up to 45W with PD and PPS support across multiple voltage profiles, and uses GaN technology for improved efficiency, but the 15W secondary port limits its overall high-power utility.
GaN technology typically results in less heat generation and thus less need for active cooling, suggesting a silent operation without fans.
The charger is UL Listed and features full-range protection functions, indicating adherence to safety and construction standards.
As a compact wall adapter, it inherently offers minimal cable management beyond its small size, and no cables are included.
Best For
- Travelers needing a compact charger for a phone and a low-power laptop or tablet.
- Users with a Raspberry Pi 5 who need a 5V/5A compatible power supply (though the product specifies 20V/2.25A for 45W, it does list 5V/3A, and Pi 5 can run on 5V/3A with limited USB power).
- Charging two smaller USB-C devices simultaneously, like a smartphone and earbuds.
- Anyone prioritizing a small footprint and safety certifications for a daily carry charger.
Not Recommended For
- Users needing to fast charge two power-hungry laptops simultaneously.
- Charging devices that require more than 45W of power, such as many 14-inch or 16-inch laptops.
- Those who need a charger with USB-A ports for older devices.
Watch Out For
- No user feedback is available to identify common issues or specific performance quirks, as the product's release date is in the future.
- The 45W total output is split between two ports, meaning you won't get 45W on both simultaneously; for example, charging a 45W device and a 15W device simultaneously will use the full 45W capacity, but two 30W devices would be throttled.
- The 'ATX' connector listed in the specs is an error for a USB-C wall charger and should be disregarded.

Frequently Asked Questions
Can this charger fast charge my iPhone and iPad simultaneously?
Yes, it can charge both, but the 45W total output is shared. Your iPhone would likely fast charge at its maximum supported wattage (e.g., 20-27W), and your iPad would draw the remaining power up to 15W from the secondary port, or vice versa, depending on which port you use for which device.
Is this charger compatible with the Raspberry Pi 5?
The charger offers 5V at 3A (15W) and other PD profiles up to 45W. While the Raspberry Pi 5 officially recommends a 5V/5A (25W) power supply, it can operate on a standard 5V/3A supply with reduced power to USB peripherals. This charger's 5V/3A output should work for the Pi 5, but you might experience limitations if you connect high-power USB devices to the Pi.
Does this charger come with any cables?
The product specifications do not mention any included cables. You will need to provide your own USB-C to USB-C cables for charging your devices.
Can I use this charger internationally?
Yes, the input voltage range is AC100-240V~50/60Hz, 1.0A Max, making it compatible with power outlets worldwide. You may need a physical plug adapter for different regions.
What does 'GaN' mean for this charger?
GaN (Gallium Nitride) is a semiconductor material that allows chargers to be smaller, more efficient, and generate less heat compared to traditional silicon-based chargers, even at higher power outputs.
Buying Guide
When you're looking at a USB-C power adapter, especially a GaN one, you're usually trying to balance power, size, and the number of devices you want to charge. Think about what you're plugging in most often. If it's just your phone, a lower wattage is fine. If it's a laptop, you need to match or exceed its charging requirements. GaN chargers are smaller and run cooler, which is a big win for travel or crowded outlets. Just remember that if a charger has multiple ports, the total wattage is often split, so check the per-port output if you need simultaneous fast charging.
Wattage (45W)
This number tells you the maximum power the charger can deliver. A 45W charger is enough for most smartphones, tablets, and many smaller laptops (like a MacBook Air or Chromebook). If your device needs more, it will charge slower or not at all. Think of it like a water hose: 45W is a good flow, but some bigger plants need a stronger stream.
GaN (Gallium Nitride)
GaN is a newer material used in the charger's internal components. It allows the charger to be much smaller and lighter than older silicon-based chargers of the same power output. It also helps the charger run cooler, which can extend its lifespan. It's like upgrading from an old, bulky CRT monitor to a slim LED display – same function, much better form.
Power Delivery (PD) & PPS
PD is a standard that allows devices to negotiate for the optimal power level, ensuring fast and safe charging. PPS (Programmable Power Supply) is an advanced part of PD that allows for even finer adjustments, which can lead to faster charging for compatible devices, especially some Android phones. It's like having a smart thermostat for your charging, adjusting the temperature precisely for comfort.
Alternatives
If 45W isn't enough for your primary device or you need higher wattage for multiple devices, search for chargers with 65W or 100W total output. If you need to charge older USB-A devices, look for chargers that include at least one USB-A port alongside the USB-C ports.
