Universal Plug Compatibility

This travel adapter covers 150-plus countries using interchangeable Type C, Type G, Type A and Type I pins. A single AC outlet accepts plugs from the US, EU, UK, AU and China so one unit replaces several region-specific adapters.

Six Devices At Once

Three USB-C ports rated at 3 A each and two USB-A ports rated at 2.4 A share a combined 5 V 6 A 30 W output for phones, cameras and power banks. Travellers needing more than six simultaneous connections or higher USB power should consider a dedicated multi-port charger.

Sustained Load Behaviour

The AC outlet handles up to 2500 W at 250 V for appliances such as dual-voltage hair dryers while the USB ports maintain their rated current during extended charging sessions. The adapter does not convert voltage so single-voltage devices must match the local supply.

Questions about this item

Which plug types must the destination country support for the JY-305B-C3 to work?

The adapter provides Type C, Type G, Type A and Type I pins, covering 150+ countries; it does not fit Type D (India) or Type M (South Africa) outlets.

Can I keep using my existing 5 V USB-A cables with the two USB-A ports?

Yes, the two USB-A ports each deliver up to 2.4 A at 5 V, so standard USB-A cables work normally alongside the three USB-C ports.

How do I confirm the unit is powered and the 30 W USB budget is active?

The built-in LED indicator lights when the AC outlet is live; the three USB-C ports share a 3 A (30 W) total and the two USB-A ports share 2.4 A each.
