19V 2.37A 45W OUTPUT WITH 4.0 × 1.35MM
SMALL TIP: Unlike generic universal chargers that force you to guess which tip fits, this adapter is engineered for ASUS laptops requiring 19V 2.37A (45W) input through the 4.0 × 1.35 mm small barrel connector. Universal input 100-240V, 50/60Hz works worldwide. Each unit is tested before shipment to confirm output matches OEM specifications, so your ASUS laptop charges reliably from first use.
IMPORTANT: This is the small-tip version NOT compatible with 5.5 mm big-tip ports. This is a 45W power supply, NOT for laptops requiring 65W or higher power. COMPATIBLE WITH ASUS ZENBOOK AND VIVOBOOK LINEUP: Engineered as a direct replacement for ASUS ZenBook UX305, UX305F, UX305U, UX330, UX330U, UX360, UX360C, UX303, UX303U series, and VivoBook X540, X540L, X540S, X541, X541U, S200, S200E models.
Note: For Q504UA, Q304UA and other 65W-original laptops, this charger ONLY works as a backup power source, NOT for heavy-duty daily use. Because voltage and amperage match ASUS OEM specifications exactly for 45W-rated models, your laptop charges without the flicker, slow-charge, or non-detection issues caused by mismatched adapters.
