Apc 550 Appraisal

APC Back-UPS 550 Uninterruptible Power Supply (UPS)

This item is an APC Back-UPS 550, a compact uninterruptible power supply (UPS) system designed to provide battery backup and surge protection for electronic devices. The unit is predominantly black in color and appears to be constructed from durable plastic, featuring a textured finish on its casing. Its physical characteristics include a rectangular, somewhat rounded form factor, approximately 3-4 inches in height and 7-9 inches in width, though exact dimensions are not measurable from the image. The top surface of the unit features a series of six electrical outlets; the left three are labeled 'Battery Backup' and 'Surge Protection,' while the right three are indicated as 'Surge Protection' only. Prominently displayed on the front panel is the 'APC' logo in red text, alongside the model name 'Back-UPS 550'. To the far right of the front panel, there's a circular power button with an illuminated ring, and two small LED indicators labeled 'Power On' (green) and 'On Battery' (yellow/amber), suggesting operational status. A black power cable with a right-angled, grounded plug is shown coiled on top of the unit or nearby, suggesting its compact storage capability. The cable itself appears to be standard household gauge wiring. In terms of condition, the device appears well-maintained with no obvious signs of significant damage such as cracks, deep scratches, or discoloration. Minor dust or slight surface wear might be present but is not clearly discernible. There are no visible manufacturing marks beyond the APC branding and model number. Given its design and features, it likely belongs to a relatively modern era of consumer electronics, possibly late 2000s to early 2010s, though UPS systems often have a longer functional lifespan. The overall craftsmanship appears to be standard for mass-produced electronics, focusing on functionality and durability rather than intricate design, which is typical for utility devices of this nature. The coiling of the cable with a twist tie indicates it has been stored or handled neatly.
