Questions about this item

What input voltage range does the 100-240VAC 50/60Hz adapter accept?

The adapter accepts a worldwide input of 100-240VAC at 50/60Hz, allowing it to operate on mains supplies in most countries without a separate voltage selector.

What are the barrel plug dimensions and polarity for the 5.5mm x 2.5mm connector?

The output connector measures 5.5mm outer diameter by 2.5mm inner diameter and is wired centre positive, matching the polarity required by compatible laptops.

How is the 6.5 Ft power cord attached, and what is the common fitting mistake?

The 6.5 Ft cord is permanently fixed to the adapter body; the frequent error is forcing the barrel plug in upside down, which reverses polarity and prevents charging.
