45W 19.5V Blue Tip AC Adapter

This JIONR SK90195231 adapter delivers 45 watts at 19.5 volts and 2.31 amps through a 4.5mm by 3.0mm blue centre pin barrel connector. It is built for HP laptops that require this exact output and tip size.

Input Range and Connector Limits

The unit accepts AC 100 to 240 volts at 1.2 amps, 50 or 60 hertz, so it works on mains supplies worldwide without a voltage switch. The fixed barrel tip fits only devices with a matching 4.5mm by 3.0mm blue pin jack; it cannot serve laptops that use USB-C, a different barrel diameter or a centre pin of another colour.

Protection Chips and Portability

Built-in multi-protection circuits guard against overvoltage, overcurrent, overheating and short circuits while maintaining a stable constant current. At 8.8 ounces the brick is light enough to carry daily, and the two-pin corded design plugs directly into a wall outlet or travel adapter without a separate cable.

Questions about this item

Should I pick the 45 W unit or a higher-wattage version?

Choose the 45 W model only if your laptop requires exactly 19.5 V at 2.31 A; a higher-wattage adapter will not charge faster and may not fit the 4.5×3.0 mm blue tip.

What does the 45 W rating mean when the adapter is plugged into my laptop?

It is the maximum continuous power the unit can deliver at 19.5 V and 2.31 A; your laptop will draw only what it needs up to that limit.

What connector standard does the 4.5×3.0 mm blue tip follow and what does it cap?

The barrel tip is a proprietary HP 4.5 mm × 3.0 mm centre-pin design that carries 19.5 V at up to 2.31 A, capping output at 45 W.
