Asus has launched a tiny 100W GaN charger that looks built for the modern backpack: one laptop, a phone, a pair of earbuds, and still a spare port for whatever else is draining power. The new adapter costs about 179 yuan, or around $25, and squeezes four outputs into a body that measures 75 x 61 x 29 mm.
That price is doing a lot of work here. A 100W multiport charger with a foldable plug and support for several fast-charging standards is already a strong spec sheet; under $25 makes it harder to ignore, especially since plenty of branded GaN chargers still hover well above that. Asus is clearly aiming at the everyday charger upgrade, not some niche accessory for spec nerds.
Asus 100W GaN charger has four ports in a pocket-size body
The charger uses a 3C+1A layout: three USB-C ports and one USB-A port. It weighs about 211 g and includes a foldable plug, which is exactly the kind of unglamorous detail that matters more than marketing copy once you start tossing it into a bag.
Asus is also offering multiple color options for the casing, though the bigger story is the layout itself. Many rival compact chargers at this power level stop at two ports; going to four makes the device more useful for travel, desk setups, and the sort of charging pileup that has become normal since laptops, phones, and wearable devices all arrived demanding their own cables.
Asus 100W GaN charger power split across phones and laptops
Used alone, the first two USB-C ports, C1 and C2, can each deliver up to 100W. The third USB-C port tops out at 20W, while USB-A can supply up to 22.5W with SCP or 18W with Quick Charge. The charger supports PD, PPS, QC, SCP, and other fast-charging protocols.
- 1 device: C1 or C2 at up to 100W
- 2 devices: 60W + 30W, or 60W + 20W/22.5W depending on the port mix
- 3 devices: 45W + 30W + 20W, or 45W + 30W + 22.5W
- 4 devices: 45W + 30W + 20W shared across the remaining ports
That makes the charger practical rather than just powerful on paper. Asus is betting that most buyers would rather carry one brick that can handle a laptop and a phone at the same time than juggle a drawer full of single-purpose chargers. The only question now is how quickly this model leaves the China-only price zone and turns into the sort of deal that gets copied, undercut, and quietly standardized across the rest of the market.
