HP AC Power Adapter Model 0957-2280 (not authenticated)

This is a rectangular black plastic AC power adapter block designed for electronic devices, held in a person's hand for scale. The physical construction consists of molded matte black thermoplastic housing with rounded corners and four circular corner indentations. The primary feature is a large printed white text and symbol label affixed to the top surface, displaying various regulatory compliance logos, safety warnings, and technical specifications. Key text visible on the label includes the HP logo, the model designation '0957-2280', an input rating of '100-240V~ 50/60Hz 650mA', an output rating of '+32V === 750mA', and a serial number barcode reading 'SN: 11460950008103WF0C'. Additional markings include UL listed symbols, CE mark, GS mark, and various international certification insignias. The item shows minor surface dust and handling wear consistent with standard usage, but no major structural cracks or deep gouges are visible on the plastic shell. The identification of the brand and model rests directly on the prominent printed text and logo on the manufacturer's label. The unit appears to date from the modern era of consumer electronics peripherals, though exact manufacturing dates are unverified. The quality of the casing and clarity of the printed label are consistent with mass-produced original equipment manufacturer accessories.

Based on what I can see in the photograph, this item presents as a black plastic AC power adapter bearing text and markings commonly associated with Hewlett-Packard, specifically displaying model number 0957-2280 and various regulatory symbols. Based on this visual evidence, an item of this type if the attribution is correct typically trades in the fifteen to thirty dollar range within the current secondary market for replacement electronics accessories. However, I can't verify internal electrical integrity, operational functionality, or manufacturing provenance from a photo alone, and would need physical inspection and electrical testing to confirm working condition. Furthermore, visible labeling can be replicated or affixed to third-party or generic adapters. If this piece proves to be a reproduction, generic equivalent, or non-functional replica rather than a standard OEM peripheral, the market value would drop to the nominal five to ten dollar range typical of generic power supplies. Demand for used power adapters is driven strictly by practical utility rather than collectible interest, meaning overall condition and safety compliance heavily dictate pricing. Physical inspection and expert evaluation of internal components would be necessary to establish a more precise assessment of value and usability.
