What the ASUS a-bean 100W GaN Charger Is and Why It Matters
The ASUS a-bean 100W GaN charger is a compact, four-port multi-port power adapter that uses gallium nitride technology to deliver up to 100W of fast charging through three USB-C ports and one USB-A port, bringing premium laptop‑class charging performance into an affordable USB-C charger that costs under USD 30 (approx. RM140). Priced at about USD 25 (approx. RM115) in its launch market, this GaN charger under 30 targets users who want a single brick that can power a laptop, phone, tablet, and accessories at once. ASUS has kept the body close to the size of a deck of cards, with a 75 x 61 x 29 mm footprint, 211 g weight, and foldable wall prongs that make it easy to throw into a backpack or carry-on without wasting space.
Ports, Power Sharing, and Fast-Charging Protocols
The a-bean’s appeal starts with its 3C+1A layout: three USB-C ports and one USB-A port. USB-C1 and USB-C2 can each deliver up to 100W on their own, so this 100W fast charger can handle many modern laptops without a separate adapter. The third USB-C port reaches 20W, while the USB-A port offers up to 22.5W via SCP or 18W with Qualcomm Quick Charge, keeping older cables useful. Power distribution adjusts as you plug in more devices: two main USB-C ports split to 60W and 30W, and all four ports active give 45W on USB-C1, 30W on USB-C2, and a shared 20W between USB-C3 and USB-A. According to ASUS’ published specifications, these allocations are enough to fast-charge a laptop while topping up a phone, tablet, and earbuds simultaneously.
A GaN Charger Under 30 That Undercuts Anker and Ugreen
In its launch market, the ASUS a-bean lands at 179 yuan, roughly USD 25 (approx. RM115), which puts it well below many rivals. As noted by coverage comparing current listings, a roughly equivalent four-port Ugreen Nexode 100W model sells for about USD 33 (approx. RM150), while similar Anker units typically reach USD 35 to USD 55 (approx. RM160–RM255). That means ASUS is undercutting established premium brands by about USD 10 to USD 30 (approx. RM45–RM140) for comparable wattage and port counts. For shoppers hunting an affordable USB-C charger, that difference is large enough to change buying decisions, not just nudge them. In practical terms, you get a 100W multi-port power adapter that covers daily travel needs for less than many single-port laptop chargers, helping democratize fast-charging tech that used to sit in a higher price bracket.
Design, Safety, and the Question of Global Availability
Beyond price and specs, the a-bean pays attention to design details. Foldable prongs keep the 211 g body pocket-friendly, while dual-tone colorways such as Cloud White with Graphite Gray or Cool Black with Fluorescent Green stand out from the usual plain black bricks. Inside, ASUS builds in protection against over-temperature, over-current, short circuits, and voltage fluctuations, aiming to avoid the safety problems that can plague no-name chargers. This matters if you plan to use one 100W fast charger as your main laptop and phone power source. The open question is where it will ship next. So far, the a-bean has only appeared on a Chinese storefront with no global rollout confirmed, and reports suggest it may not leave that market soon. For now, this GaN charger under 30 is a compelling sign of where pricing could go if it reaches wider shelves.
