HP 32V/16V Dual-Output AC Power Adapter — Precision Energy Solution for Imaging Hardware ⚡🖨️

The HP Model: 0957-2178 is a specialized dual-voltage power supply engineered specifically for high-performance HP imaging and printing equipment. Unlike standard single-voltage adapters, this unit provides two distinct power rails—32V and 16V—to simultaneously power different internal mechanical and logic systems with precision.

Designed with a professional 3-pin (IEC C14) inlet, this adapter ensures a grounded, stable connection for sensitive office and technical hardware.

Key Performance Features

• Synchronized Dual-Voltage Output: Features a complex output of +32V at 940mA and +16V at 625mA, providing the exact power profile required by specialized HP internal components.

• Grounded IEC C14 Inlet: Equipped with a standard 3-pin computer-style socket, offering an earthed connection that enhances user safety and minimizes electrical noise.

• Proprietary HP 3-Pin Connector: Utilizes a specialized grey, keyed 3-pin output plug to ensure a secure, correct-polarity connection to your device.

• Universal Input Support: Engineered for global compatibility with an auto-switching AC input range of 100–240V, 50/60Hz.

• Comprehensive Safety Certification: Fully tested and compliant with international standards, including TÜV, GS, CE, and NOM, featuring advanced short-circuit protection.

• Energy Efficient Design: Optimized for efficient power conversion to reduce heat generation during long printing or scanning cycles.

Technical Specifications

• Input Voltage: 100–240V ~ 1A, 50/60Hz.

• Output 1: DC +32V === 940mA.

• Output 2: DC +16V === 625mA.

• Output Interface: Specialized HP 3-Pin Keyed Connector (Grey).

• Input Interface: 3-Pin IEC C14 (Standard Desktop style).

• Manufacturing: Produced by Bestec for HP.

Typical Applications

• HP Deskjet & Officejet Printers: The primary replacement power source for various Deskjet, Officejet, and Photosmart series printers.

• HP All-in-One Systems: Powers multifunction scanning and printing units requiring dual-voltage rails for motor and sensor operation.

• Legacy HP Imaging Gear: Compatible with a wide range of HP peripherals identified by part number 0957-2178.

Top 3 Customer Questions & Concerns 🙋‍♂️

⚡ Why does this adapter have two different voltages? HP printers often use 32V to drive mechanical components like paper-feed motors, while using 16V for the electronic logic boards and sensors. This adapter handles both requirements through a single cable.

📏 Will this fit any 3-pin device? No. The output plug is a specialized, keyed connector specifically shaped for HP printers. Always verify that your original adapter matches part number 0957-2178 before purchasing.

🔌 Does it include the wall power cord? This unit features an IEC C14 inlet. To connect it to a wall outlet, you will need a matching 3-pin "Kettle" style power cable (C13) that fits your local regional socket.
