TSKYBEAR 45W AC Adapter 4.5x3.0mm Blue Tip

The TSKYBEAR SK90A195231 is a new 45W AC adapter with a 4.5mm x 3.0mm blue tip connector. It delivers 19.5V at 2.31A for compatible HP laptops including Pavilion, EliteBook and Chromebook models. The unit includes short-circuit and over-voltage protection for safe operation.

Suits HP owners needing a 45W replacement

Buyers whose laptops require a different connector size, a higher wattage such as 65W or 90W, or a different output voltage should look at other adapters. This model is not for devices that use USB-C Power Delivery or barrel plugs other than 4.5mm x 3.0mm.

4.5mm x 3.0mm blue tip connector decides fit

The adapter only works when the laptop charging port matches this exact barrel size and centre-pin configuration. Verify the original charger tip dimensions and the required 19.5V 2.31A rating before ordering to ensure compatibility.

Questions about this item

Does my laptop need a 4.5x3.0mm blue-tip connector to use this 45W adapter?

Yes, the connector is 4.5mm by 3.0mm with a blue tip; it matches HP models that require that exact plug size.

Will the 100-240V input let me keep using my existing AC power cord when travelling abroad?

The adapter accepts 100-240V at 50-60Hz, so the same cord works worldwide; only a local plug adapter may be needed.

How can I confirm the charger is delivering 19.5V at 2.31A after I plug it in?

The unit is certified by CE and FCC and includes over-voltage, short-circuit and over-temperature protection that activate automatically when the adapter is operating correctly.
