Universal Travel Adapter

The Winstars JY-305B-C3 is a compact travel plug adapter that combines Type C, Type G, Type A and Type I pins in one unit. It provides a universal AC outlet rated for 250 volts and five USB ports with a total output of 5 volts at 6 amps (30 watts). The adapter is designed for travellers who need to connect devices from multiple regions through a single accessory.

For travellers with multiple USB devices

This adapter suits anyone who wants to charge up to six devices at once — three USB-C ports at 3 amps each, two USB-A ports at 2.4 amps each, plus the AC outlet. It works in 150 plus countries across Europe, the UK, North America, Japan, Australia and more. It does not convert voltage, so appliances rated only for 120 volts cannot be used in 240 volt regions. Buyers who need a voltage step-down converter or who travel to India or South Africa should look at something else.

30 watt combined USB output

The single specification that decides fit is the total USB power budget of 5 volts at 6 amps (30 watts). If your phone, tablet, power bank and other USB gear can share that 30 watt pool, the adapter will charge them all together. If you need more USB power for larger laptops or faster simultaneous charging, this unit will not meet that need.

Questions about this item

What does the package include and do I need extra cables?

The box contains the Winstars JY-305B-C3 adapter with Type C, G, A and I plugs plus a storage bag. No separate cables are included; you connect your own USB-C or USB-A leads directly to the three USB-C and two USB-A ports.

How do I decide which plug type to use?

Slide out the Type C plug for most of Europe, Type G for the UK and Ireland, Type A for the USA, Canada and Japan, or Type I for Australia and China. Only one plug is extended at a time to match the local socket.

What does the 30 W total USB output mean when I charge several devices?

All five USB ports share a 5 V 6 A (30 W) budget. If you plug in a phone, a power bank and a camera together, the adapter splits the current so the combined draw never exceeds 6 A.
