85 W 20 V Blue-Tip Adapter

This DELL SK90195333 AC adapter delivers 85 W at 20 V with an 11.8 A output and a 4.5 x 3.0 mm blue tip. It supports fast charging and operates on 110 to 240 V input. The unit is ETL listed and ships new with a power cord included.

For HP Smart Blue Tip Laptops

It suits owners of compatible HP Pavilion x360, EliteBook, ProBook, Stream, Chromebook and ZBook models that require a 65 W or 45 W smart blue-tip charger. Buyers whose laptops use a different tip size, a higher wattage brick or a non-smart connector should look at something else.

Check Tip and Wattage First

Verify that your original charger uses a 4.5 x 3.0 mm blue tip and is rated for 65 W or 45 W at 19.5 V. Confirm the part number matches SK90195333 or the listed HP equivalents such as 710412-001 or L24008-001 before ordering.

Questions about this item

What laptop power port does the 4.5 x 3.0 mm blue tip fit?

The blue tip matches HP Smart Blue Tip sockets found on Pavilion x360, EliteBook 830, 840 G3 G4 G8, 850 G3 G4, ProBook 430 G8, 440 G8, 450 G3 G8, 640 G2 G3 G4, 650 G2 G3, Stream 11 Pro G3 G4 EE, Chromebook 11 EE G2 G3 G4, Notebook 15 and ZBook 14u 15u models.

Will this 85 W adapter safely charge a laptop that originally used a 45 W or 65 W charger?

Yes. The adapter delivers up to 85 W at 20 V 11.8 A and also supports the 19.5 V 3.33 A 65 W and 19.5 V 2.31 A 45 W profiles, so it will negotiate the lower power your older laptop requires.

How can I confirm the adapter is delivering power after I plug it in?

The laptop charging indicator should light up and the battery icon will show a charging state; the adapter accepts 110–240 V input so it works on any mains supply without a voltage switch.
