Eaton PV100USB – 100W PowerVerter Compact Car Inverter

Overview :

The Eaton PV100USB is a compact DC‑to‑AC power inverter designed to convert 12 V vehicle battery power into standard 120 V AC mains power with auxiliary USB charging capability. It is deployed by field technicians, mobile engineers, and service crews who require portable AC power for low‑draw electronics and USB‑powered devices while working onsite, traveling in vehicles, or operating in mobile offices. Its ultra‑compact form factor plugs directly into a vehicle cigarette lighter (12 V) socket and provides a small AC outlet plus USB ports for simultaneous device power.

From a deployment perspective, the unit delivers 100 W continuous AC output with a peak surge capacity of 200 W, sufficient for laptops, small power tools, communication devices, lighting, and other low‑power equipment. It includes a NEMA 5‑15R AC outlet plus dual USB‑A charging ports (2.1 A and 1.0 A) for direct charging of mobile devices without external adapters.

The PV100USB fits mobile and field environments such as service vehicles, marine vessels, RVs, and remote workstations lacking fixed AC distribution. Its integrated 3 ft cord with cigarette lighter plug simplifies deployment without permanent vehicle wiring and minimizes installation complexity.

Integration into electrical ecosystems requires only a standard 12 V DC accessory socket. The inverter’s built‑in fan provides thermal management under load, and automatic shutdown protects the host vehicle battery from deep discharge by disabling output below ~10 V input. A front‑panel LED indicates DC input presence and operational status, aiding quick diagnostics in mobile deployments.

In a practical field deployment, a maintenance engineer can power a laptop and charge smartphones simultaneously while parked at a service site using a single inverter unit. The USB ports reduce reliance on multiple chargers, simplifying mobile kit configuration.

This device should not be used for high‑draw AC loads (e.g., power tools >100 W, heaters) or as a primary power source in fixed installations; it is specifically tailored for low‑power, short‑duration usage tied to vehicle DC systems. Additionally, it lacks true sine‑wave output, which may affect very sensitive electronics.
