240W AC Adapter for Dell Thunderbolt Docks

This 240W AC adapter supplies 19.5V at 12.3A through a 7.4*5.0mm connector. It is built for Dell Thunderbolt docks such as the TB18DC and WD15, plus Precision 7520, 7720, 7730 and Alienware 17 models. Buyers who need a replacement for the original 450-AEUO or 450-AHHE charger will find a direct fit.

Input range limits worldwide use

The unit accepts 100-240V at 50/60Hz, so it works on mains supplies in most countries when paired with the included US plug cord. It cannot operate outside that voltage or frequency window. Travellers heading to regions with different plug standards will need a separate passive adapter for the wall socket.

240W maximum output decides suitability

The adapter delivers up to 240W, matching the peak draw of the listed docks and laptops. Systems that require more than 240W will not run reliably from this unit. Buyers should confirm their device’s rated input power before purchase.
