## Description

Travellers who need to charge several devices from one wall outlet can use the One Beat OB4W4US to create a compact charging point for a cruise cabin, hotel room or other travel stop.

Its three-sided layout provides four AC outlets and four USB ports, including two USB-C ports. The 20W total USB output gives phones and other USB devices a shared place to charge.

The extender plugs directly into the wall, with no extension cord, and is also suited to a home office or dorm room. Its non-surge-protector design is a practical detail for cruise travel, ship policies can vary, and some Disney and Royal Caribbean ships may not allow it.

## Best use cases

Use the extender when one wall outlet needs to serve both plug-in equipment and USB-charged devices. In a hotel room, for example, its AC sockets can accommodate devices with compatible plugs while the USB ports provide charging access for cell phones. At a desk or in a dorm room, the three-sided arrangement spreads the outlets around the plug rather than placing every connection in one straight line.

For travel, the compact, cord-free format is easy to pack and avoids carrying a separate power bar with an extension cord. It is described as suitable for cruise ships, hotels, flights, home offices and beach holidays. Cruise rules differ by ship, so check the policy for your sailing, some Disney and Royal Caribbean ships may not permit this type of extender.

## What stands out

The main advantage is having AC and USB connections together in one wall-mounted unit. Rather than choosing between a basic multi-outlet adapter and a separate USB charger, this extender brings both functions into the same compact format. Four AC outlets serve plug-in devices, while four USB ports provide charging connections for phones and other USB electronics. The USB output is shared, with a total rating of 20W.

Its three-sided layout is designed to keep the outlet arrangement space-conscious and avoid blocking other wall outlets. The direct-plug design also means there is no cord to manage in a suitcase or around a bedside table. That makes it a useful fit for travellers packing light, as well as for everyday charging in a home office or dorm.

The product is identified as a non-surge-protector, cord-free extender for cruise travel. It is listed for use on major cruise lines, while some ships operated by Disney and Royal Caribbean may not allow it. The ETL and FCC certifications are also listed, offering useful product details when comparing travel charging adapters.

## Final verdict

The One Beat OB4W4US is built for people who want several charging connections in one compact wall adapter, especially when travelling with both plug-in and USB-powered devices. Its four AC outlets, four USB ports, two USB-C connections and 20W total USB output make it a practical charging hub for a hotel stay, cruise trip, dorm room or home office. Choose it when a direct-plug, cord-free format suits your setup and the outlet rules at your destination.
