Direct laptop power

The Dell SK90A195231 is an 85 watt AC adapter that supplies 20 volts at 11.8 amps to compatible laptops. It replaces a lost or damaged original charger and restores full charging speed for supported Dell models.

Proprietary connector fit

A fixed 4.5 millimetre barrel tip mates with the laptop's DC jack without adapters or loose connections. The unit draws from a standard IEC C7 mains lead and delivers regulated output through a single captive cable.

Multi-shield protection active

Flame-retardant housing and built-in sensors guard against over-voltage and short circuits during extended sessions. Strain-relief joints are tested to ten thousand bends, and the adapter weighs 0.272 kilograms for easy transport.

Questions about this item

How much power can the 85W adapter deliver continuously before it hits its limit?

The adapter is rated for 85W output at 20V and 11.8A, so that is the maximum continuous power it can supply.

Does the 85W unit run hot or make noise when left on all day?

The adapter uses passive cooling with no fan, so it operates silently; heat will depend on load and ventilation but no acoustic noise is produced.

Which connector does the 4.5mm Smart Blue Tip fit on my laptop?

The 4.5mm Smart Blue Tip connector is designed for compatible HP Pavilion and Stream models that accept this proprietary tip.
