Chopmate 90W USB-C Laptop Charger for HP 20V 4.5A

What this charger replaces

The Chopmate 90W USB-C adapter is a new replacement power supply for a wide range of HP laptops including Spectre x360 15-inch models, EliteBook 745 G5 and G6, Envy x360, EliteBook 1040 G4 and ZBook x2 G4. It delivers up to 20V at 4.5A for 90W maximum output and also supports 20V 3.25A 65W and 20V 2.25A 45W profiles. The unit accepts 100-240V 50/60Hz input for worldwide use.

Check your laptop before ordering

Verify that your HP model appears in the supported list such as Spectre x360 15-bl075nr, 15-ch000 series or EliteBook 745 G5 and G6. Confirm the original charger uses a USB-C connector and requires 20V 4.5A 90W output. The adapter will not fit laptops with barrel connectors or different voltage requirements. Match the part numbers like L45440-001, 2VY99EA or 2PN61EA to be certain.

Thermals noise and power draw

The adapter operates from a 100-240V AC supply and converts it to 20V DC at up to 4.5A with UL safety testing. It runs silently with no moving parts and typical efficiency keeps the casing warm but not hot during normal charging. Power draw at the wall scales with the laptop load up to the 90W rated maximum.
