⚙️ Fit Notes

• Confirm 19V DC output, 90W power, and the 5.5mm × 2.5mm connector before ordering.
• The 5.5mm measurement is the outside barrel diameter; 2.5mm is the inside opening.
• A 5.5mm × 2.1mm plug is a different connector and should not be treated as equivalent.
• This adapter does not use a center identification pin.
• A 65W or 75W adapter is not an equivalent replacement for a system requiring 90W.
• Do not use this adapter for a configuration requiring more than 90W.
• Match the barrel length and available clearance around the charging port as well as its diameter.
• The 100–240V input supports different mains voltages; the wall-plug style must match the outlet used.
