SKU CH-0A0A-HRBQA

  • TypeAC Adapters
  • UL-certified safety meets US gold-standard requirements
  • 65 W output powers 45 W and 65 W laptops alike
  • 100–240 V input works worldwide without a converter
  • Round 4.5 × 3.0 mm tip fits Inspiron and Vostro models
  • Included 7.4 × 5.0 mm converter cable expands compatibility

Purpose and compatibility

This 65 W AC adapter powers Dell Inspiron, Latitude and Vostro laptops that use a round barrel connector. It also supports 45 W models, so one unit covers both common power ratings. A 4.5 × 3.0 mm to 7.4 × 5.0 mm converter cable is included for the larger connector variant. The adapter accepts 100–240 V input for worldwide use.

Sustained output behaviour

The unit delivers up to 65 W continuously at 19.5 V and 3.34 A without throttling. When connected to a 45 W laptop it supplies only the current the device requests, so there is no risk of over-powering the system. UL certification confirms the design meets recognised safety limits for continuous operation.

Thermals noise and power draw

The adapter runs on universal 100–240 V mains and produces no audible fan noise because it has no moving parts. Heat is dissipated through the sealed enclosure during normal charging cycles. Power draw at the wall matches the laptop’s actual consumption plus typical conversion losses.

Questions about this item

How much heat or noise does the 65W 19.5V 3.34A adapter produce when powering a laptop continuously?

The adapter runs silently with no fan; normal warmth is expected during full-load operation but it stays within UL safety limits.

Which cables or converters must I already have to connect this 4.5 X 3.0 mm round tip to my laptop?

The box includes a 4.5 X 3.0 mm to 7.4 X 5.0 mm converter cable and a mains power cord, so no extra parts are required.

Will this 100-240V input charger safely run an older Dell Inspiron or Vostro that originally shipped with a 45W brick?

Yes — the 65W output covers 45W models and the round connector fits the listed Inspiron and Vostro series.
