myVolts 7.4mm to 4.5mm DC Dongle Tip Adapter (2 Pack)

SKU CH-NR93-M5B5W

Converts a 7.4x5.0mm barrel plug to a 4.5x3.0mm tip for compatible HP laptops, two adapters included

  • Converts 7.4x5.0mm power plugs to 4.5x3.0mm laptop ports
  • Supports 18.5V, 19V and 19.5V charger voltages
  • Two adapters included for spare or multi-device use
  • Fits Pavilion, Spectre, Envy, EliteBook, ProBook and Stream models
  • Black DC dongle with centred pin for secure connection

What the adapter does

This adapter converts a 7.4x5.0mm female DC plug into a 4.5x3.0mm male tip with a centre pin. It lets an existing power supply with the larger connector charge laptops that require the smaller barrel size. The pack contains two black dongles for spare or multi-device use. Voltage compatibility covers 18.5V, 19V and 19.5V outputs.

Suits owners of listed HP models, not other brands

Builders with HP Pavilion, Stream, Spectre, Envy, EliteBook Folio 1040 G1, ProBook G3 or Split x2 notebooks that use a 4.5x3.0mm charging port can use these tips. Users whose laptops need a different barrel diameter, pin arrangement or voltage outside the 18.5V to 19.5V range should look elsewhere.

Connector size decides fit

The critical specification is the converter INPUT of 7.4x5.0mm female and OUTPUT of 4.5x3.0mm male with pin. Match these exact dimensions to your power supply plug and laptop charging port before purchasing.
