What a 100W GaN Charger Is and Why ASUS’s a-bean Matters
A 100W GaN charger is a compact wall adapter built with gallium nitride components that can deliver up to 100 watts of power through modern USB ports, enabling fast charging for laptops, phones, and accessories from a smaller, cooler-running device than traditional silicon chargers. ASUS’s new a-bean model aims squarely at the affordable fast charger segment by combining this high output with a multi-port USB-C charger layout and a low launch price. Priced at about USD 25 (approx. RM115) in its home market, the a-bean offers three USB-C ports plus one USB-A port in a body roughly the size of a deck of cards. That combination of 100W ceiling, four-port flexibility, and budget charging accessory positioning puts direct pressure on better-known brands like Anker and Ugreen, which sell similar hardware at higher prices.
ASUS a-bean 100W GaN: Specs, Ports, and Real-World Use
The ASUS a-bean 100W GaN charger measures 75 x 61 x 29 mm, weighs about 211 g, and includes foldable wall prongs for easier packing in a bag or pocket. Its 3C+1A layout provides three USB-C outputs and one USB-A, with the two primary USB-C ports (C1, C2) each capable of delivering up to 100W on their own, enough to fast-charge many thin-and-light laptops. The third USB-C port supports up to 20W, while the USB-A port reaches 22.5W via SCP or 18W with Qualcomm Quick Charge. Power distribution adapts as you add devices: two main USB-C ports share 60W and 30W, while all four ports together deliver 45W on C1, 30W on C2, and a shared 20W for C3 and USB-A. Supported standards include USB Power Delivery, PPS, QC, SCP, FCP, QFC, and PE.
Price Gap: ASUS vs Anker and Ugreen on Budget 100W GaN Chargers
According to The Eastern Herald, the ASUS a-bean 100W GaN charger launched at 179 yuan, or roughly USD 25 (approx. RM115), while comparable four-port 100W units from Anker and Ugreen often range between USD 35 (approx. RM160) and USD 55 (approx. RM250) in major Western markets. Gizmochina notes that the Ugreen Nexode 100W, with a similar wattage ceiling and multi-port layout, lists around USD 33 (approx. RM150) on Amazon in some regions. That makes ASUS’s unit meaningfully cheaper by USD 10 (approx. RM45) to USD 30 (approx. RM140) for buyers who can access its launch market. The trade-off is availability: ASUS has not announced broader distribution for the a-bean, while Anker and Ugreen focus on wide retail presence, warranty coverage, and regional certifications that add cost but improve convenience and after-sales support.
Design, Portability, and Safety Compared with Premium Rivals
ASUS positions the a-bean as a compact, travel-friendly alternative to premium 100W GaN bricks. Its foldable prongs and deck-of-cards footprint compete well with established multi-port USB-C charger designs from Anker and Ugreen, which use similar GaN-based layouts but often at higher prices. ASUS also leans on style: the a-bean ships in dual-tone color combos such as Cloud White with Graphite Gray and Cool Black with Fluorescent Green, a more lively approach than the usual matte-black blocks found in this category. On the safety front, ASUS includes protection against over-temperature, over-current, short circuits, and voltage fluctuations, addressing the main failure modes that can turn a budget charging accessory into a risk. While Anker and Ugreen promote similar safeguards, ASUS’s branding and safety focus help distinguish the a-bean from anonymous low-cost chargers that may cut corners.
Who Should Buy ASUS, Anker, or Ugreen?
For users who can purchase the a-bean at its launch price, ASUS offers one of the most affordable fast charger options in the 100W category, with enough power allocation to charge a laptop, phone, tablet, and earbuds at once. Its broad support for PD, PPS, and other fast protocols makes it a practical multi-device hub. However, global pricing and availability remain uncertain, and ASUS already sells different, more expensive models elsewhere. Anker and Ugreen still appeal to buyers who value easy access through local retailers, established service networks, and regional certifications. In practice, the choice comes down to availability and risk tolerance: if importing the a-bean is straightforward, it delivers strong value as a budget charging accessory; if not, a slightly pricier Anker or Ugreen multi-port USB-C charger may be the more convenient long-term option.
