Kenuco 65W 45W Smart Blue Tip AC Adapter 4.5x3.0mm

SKU CH-72N7-1RTEQ

Delivers up to 65W at 19.5V via a 4.5x3.0mm blue tip with multi-protection for compatible HP laptops

  • TypeAC Adapters
  • Delivers up to 65W for demanding workloads
  • Also powers 45W devices with the same adapter
  • Works worldwide on 110-240V input voltage
  • Blue tip connector sized 4.5 x 3.0 mm fits listed HP models
  • Multi-protection guards against over-voltage and short-circuit

Compatible HP Laptop Charger

This 65W AC adapter replaces the original power supply for a wide range of HP ProBook, Envy and Pavilion models. It delivers up to 19.5V at 3.33A and automatically supports 45W devices as well. The unit accepts 110-240V input for worldwide use.

Blue Tip 4.5x3.0mm Connector

The charger uses a blue smart-tip barrel plug measuring 4.5mm outer diameter by 3.0mm inner diameter. This specific tip size and signalling protocol determine whether the laptop will recognise and charge from the adapter.

Straightforward Replacement

Plug the barrel tip into the laptop’s power jack and connect the IEC mains lead to a wall socket; no drivers or configuration are required. The most common issue is selecting a charger with the wrong tip dimensions or wattage, which prevents the laptop from charging or triggers an incompatible-charger warning.

Questions about this item

What does the 65 W output actually deliver to a compatible HP laptop?

It supplies up to 19.5 V at 3.33 A, providing full 65 W charging and also covering models that only need 45 W.

How does the smart blue-tip connector limit what can be charged?

The 4.5 x 3.0 mm blue tip works only with HP laptops that use that specific smart-pin interface; other barrel sizes or brands will not connect.

What clearance does the 4.5 x 3.0 mm tip need around the laptop's charging port?

The plug requires a straight, unobstructed port opening that accepts a 4.5 mm outer diameter and 3.0 mm inner pin without adjacent plastic ribs blocking insertion.
