Replacement 45 W HP Adapter
This GCROWN 45 W AC adapter delivers 19.5 V at 2.31 A for compatible HP laptops. It accepts 100-240 V AC input at 50-60 Hz for worldwide use. The package includes the adapter unit and an AC power cable. A blue-tip 4.5 × 3.0 mm connector fits the listed models.
Upgrading From a Failed Original
The unit replaces a lost or faulty factory charger for supported HP Pavilion, EliteBook Folio, TouchSmart and Stream notebooks. It matches the original 45 W output specification so performance stays unchanged. The jump is worth it when the original adapter no longer powers the laptop or charges the battery. Buyers who need a higher-wattage supply for larger models cannot use this adapter.
Limits of the 4.5 mm Barrel Interface
The fixed 4.5 × 3.0 mm barrel connector only fits devices designed for that tip size and polarity. It cannot charge laptops that require USB-C Power Delivery or a different barrel diameter. The 45 W ceiling also means it will not run systems that draw more power under load. Buyers who want a universal multi-tip charger or a GaN form factor should look elsewhere.
