US Plug Power Adapter

Pacoli Power’s US Plug Power Adapters deliver dependable DC power designed for the electrical system used across North America. We support all regional plug architectures, including Type A (two-prong) and Type B (three-prong grounded) formats. Our adapters integrate high-grade transformers and robust isolation for consistently safe operation.

We provide a vast range of models with varying output capacities to match any application requirement, from low-power devices to demanding industrial equipment. Built-in over-voltage, over-current, and short-circuit protections ensure safe operation. Certified under UL, ETL, FCC, and DOE Level VI efficiency standards, many models accept universal input (100–240 V) for international deployment. Pacoli Power specializes in OEM/ODM solutions that comply with NEMA standards. We fully customize all electrical parameters - including the output voltage and current, connector types, cable lengths, and housings - delivering power solutions ideal for powering everything from routers and POS terminals to medical peripherals and industrial devices.

FAQ

Frequently Asked Questions

What is the difference between Type A and Type B US plugs?

Type A plugs have two flat prongs and are not grounded, while Type B plugs add a round grounding pin for safety. Grounded Type B sockets accept both plug types. Grounding protects users from electric shocks if a fault occurs.

Do Pacoli US plug adapters work worldwide?

Many of our US plug adapters accept 100–240 V input at 50/60 Hz. For global travel, choose a dual‑voltage model and use a simple plug‑shape adapter to fit local sockets.

Are your US plug adapters UL‑listed and DOE compliant?

Yes. Our US models meet UL 62368‑1 or UL 60950 standards, DOE Level VI or Level VII efficiency requirements, and FCC Part 15 for electromagnetic compatibility. We also offer ETL‑listed versions.

Can I use a higher‑wattage adapter with a low‑power device?

Yes. As long as the adapter’s output voltage matches your device’s requirements, a supply with a higher current rating is safe. Never exceed the voltage listed on your device.

What devices can these US plug adapters power?

Our US plug adapters support routers, modems, CCTV cameras, LED lighting, smart home hubs, POS systems, medical peripherals (non‑life‑support), battery chargers, and small industrial controllers.

Do I need a voltage converter for US devices in Europe?

Check your device’s input label. If it says “100‑240 V, 50/60 Hz”, it is dual‑voltage and only requires a plug adapter. If it says “120 V, 60 Hz”, you need a voltage converter when using it in Europe to avoid damaging the device.
