HP 90W Slim Adapter with USB

The HP BT796UT#ABA is a 90W Slim AC Adapter designed for HP Business Notebooks and USB devices. It delivers 1.6 A at 90 VAC and 0.85 A at 180 VAC input. Integrated surge protection guards connected hardware against power fluctuations. The single USB port allows convenient charging of a phone or accessory alongside the laptop.

Steady 90W delivery under load

The adapter maintains its full 90W output during continuous operation rather than only in short bursts. Smart Adapter technology communicates with the notebook to regulate power draw efficiently across multiple compatible families. Surge protection remains active throughout extended sessions to prevent damage from unstable mains supply. Energy-efficient design reduces waste heat during prolonged use.

Compact build with integrated cable management

The slim profile fits easily into a travel bag without adding bulk. A single barrel connector plugs into the notebook while the USB port stays accessible for peripheral charging. Integrated strain relief on the cables withstands daily connect and disconnect cycles. The unit is built to HP Smart Adapter standards for cross-family compatibility.

Questions about this item

How much heat or noise does this 90W slim adapter produce when running continuously?

It is a fanless external power supply, so it operates silently; warmth will be noticeable on the casing during prolonged use but stays within normal limits for a 90W unit.

What must I already own for the USB port on this adapter to charge a device?

You need a USB cable that matches your device’s connector and a notebook compatible with the adapter’s output so the USB port receives power.

Can I use this adapter with an older HP notebook that originally shipped with a different wattage charger?

Yes, provided the older notebook’s power jack and voltage requirements match the adapter’s output; the unit will deliver up to 90W and the notebook draws only what it needs.
