Power adapter inverter HP 397803-001, indoor laptop power supply, 135 W, 100–240 V, black

HP 397803-001 is a 135 W indoor laptop power adapter designed to provide reliable mains power for compatible HP notebooks. The compact black adapter accepts a wide input range of 100–240 V AC at 47–63 Hz and delivers 19.0 V DC output with a maximum power of 135 watts. Supplied as a single unit, this power adapter functions as a replacement or spare charger for desk and travel scenarios where an indoor mains outlet is available; a separate 3‑wire AC power cord with a C5 connector is required for connection to local mains sockets.

Advantages

The adapter supports universal mains voltage, simplifying use across regions without a dedicated voltage converter. Its 135 W rating provides adequate power for higher-performance notebooks and charging during use. The single black unit is compact enough for carrying in a laptop bag yet robust for frequent indoor use. Designed for direct DC output at 19.0 V, it delivers stable power for compatible laptop charging and operation.

Suitable for

• Replacing a lost or damaged indoor laptop power adapter
• Keeping a spare charger at the office or home
• Powering compatible HP notebooks that require 19.0 V DC and up to 135 W
• Travel where indoor mains power is available and a C5 power cord can be used

How to use

Connect a compatible 3‑wire AC power cord with a C5 connector to the adapter's AC inlet, then plug the cord into an indoor mains outlet within the 100–240 V range. Attach the adapter's DC output plug to the laptop power input port designed for 19.0 V. Ensure the connection is firm and observe the laptop's charging indicator to confirm power delivery. Unplug the AC cord from the mains before disconnecting the DC connector when not in use.

Usage recommendations

Use the adapter indoors only and avoid exposure to moisture or extreme temperatures. Verify that the target notebook accepts 19.0 V DC and that its power requirement does not exceed 135 W. Use an appropriate regional C5 AC power cord rated for local mains voltage and safety standards. If the laptop exhibits power issues, inspect connectors for damage and replace cords or the adapter as necessary.
