Dell VJCHS PA-1131-28D1 LA130PM121 Power Supply Adapter

The Dell VJCHS PA‑1131‑28D1, also labeled LA130PM121 (and equivalent to DA130PE1‑00), is a genuine Dell 130 W slim AC power adapter. Designed for a vast array of Dell laptops—including Inspiron, Latitude, Precision, XPS, and select Alienware models—it delivers a stable 19.5 V at 6.7 A output via the proprietary 7.4 × 5.0 mm barrel Smart‑Tip connector with center pin. With universal input support (100–240 V AC, 50–60 Hz), it’s ideal for global travel. The adapter body measures approximately 154 × 77 × 26 mm, and weighs between 330–525 g, depending on variant and region. It provides built‑in safety features: over‑current, over‑voltage, short‑circuit, and thermal protection. Backed by Dell’s reputation, the adapter ensures reliable power delivery under demanding workloads and leverages an internal ID chip to ensure laptop‑side authentication and optimal performance. Its slim form factor and efficient thermal design make it more portable and better suited to mobile use than earlier bulky "brick" designs.
