What a 100W GaN Charger Is and Why ASUS a-bean Matters
A GaN charger 100W is a compact power adapter built with gallium nitride components that can deliver up to 100 watts of fast charging through one or more ports, replacing larger silicon-based bricks for phones, laptops, and accessories. The ASUS a-bean charger takes this concept and pushes it into budget fast charger territory at about USD 25 (approx. RM115) in its launch market. It packs four outputs – three USB-C and one USB-A – into a body roughly the size of a deck of cards, measuring 75 x 61 x 29 mm and weighing around 211 g. Foldable prongs help it slide into a laptop sleeve or travel pouch without snagging. For buyers comparing a multi-port USB-C charger from Anker or Ugreen, the a-bean’s appeal is clear: similar 100 W headline power, more ports than many laptop bricks, and a noticeably lower entry price.
Ports, Power Sharing, and Real-World Charging Scenarios
ASUS gives the a-bean 3C+1A layout: USB-C1 and USB-C2 can each output up to 100 W alone, USB-C3 reaches 20 W, and the USB-A port supports up to 22.5 W via SCP or 18 W with Quick Charge. According to Gizmochina, the charger can fast-charge a laptop from a single USB-C port while leaving others free for smaller devices. Once you plug in more devices, the power budget redistributes. Two main USB-C ports share 60 W and 30 W; pairing USB-C1 with USB-C3 delivers 60 W + 20 W; combining USB-C1 and USB-A yields 60 W + 22.5 W. With three outputs active, users see modes like 45 W + 30 W + 20 W or 45 W + 30 W + 22.5 W. All four ports engaged provide 45 W on C1, 30 W on C2, and 20 W shared between C3 and USB-A, enough to cover a laptop, phone, earbuds, and another accessory at once.
Price Gap: ASUS a-bean vs Anker and Ugreen 100W Chargers
In its home market, the ASUS a-bean 100W GaN charger sells for 179 yuan, about USD 25 (approx. RM115). That figure is where the comparison with established brands becomes sharp. The Eastern Herald notes that similar 100 W multi-port USB-C charger models from Anker and Ugreen typically land between USD 35 and USD 55 (approx. RM160–RM250) in other markets, making the a-bean cheaper by about USD 10 to USD 30 (approx. RM45–RM140) at face value. As Gizmochina highlights, Ugreen’s Nexode 100W with a comparable port layout lists around USD 33 (approx. RM150), while Anker’s four-port chargers often sit higher. This means ASUS is positioning the a-bean squarely as a budget fast charger without cutting the power ceiling or the port count. The trade-off is availability: the a-bean has launched locally, with no confirmed global rollout or localized pricing.
Protocols, Safety, and Design: Do You Lose Anything for Less?
On paper, the ASUS a-bean charger tracks premium rivals closely in features despite its lower price. It supports a wide range of fast-charging standards, including USB Power Delivery, PPS, Qualcomm Quick Charge, Huawei SCP, FCP, QFC, and PE. That coverage means the multi-port USB-C charger can handle laptops, Android phones, tablets, and legacy USB-A gadgets without needing brand-specific bricks. The Eastern Herald reports that ASUS includes protection against over-temperature, over-current, short circuits, and voltage fluctuations, addressing common safety concerns with cheap chargers. Design-wise, the a-bean uses foldable prongs and offers three dual-tone color schemes such as Cloud White with Graphite Gray and Cool Black with Fluorescent Green, giving it a more lively look than plain black blocks. For most users, the main sacrifice is not capability but regional access and the uncertainty of whether this aggressive price will appear in their local stores.
Who Should Consider the ASUS a-bean 100W GaN Charger?
For anyone carrying a laptop, phone, and one or two small accessories, the ASUS a-bean 100W GaN charger offers a strong one-brick solution. Its dual 100 W-capable USB-C ports can replace many stock laptop adapters, while USB-C3 and USB-A keep smaller devices topped up. Travelers gain from the foldable prongs and relatively compact dimensions, especially when trying to minimize cables and bricks. Power users who often charge four devices at once will appreciate clear allocation schemes like 45 W + 30 W + 20 W shared, which still keeps a thin-and-light laptop in fast-charge territory. The catch is availability and potential price inflation outside the launch market; ASUS’s global catalog still emphasizes higher-priced models like the AC100-02. If and when the a-bean appears elsewhere, it will stand out as a budget fast charger that meets, rather than trails, Anker and Ugreen on core performance.
