Which of your chargers need an adapter
Look at the plug first. A type A plug has two flat parallel pins; a type I plug has two flat pins in a V shape, with an earth pin. Both fit the Chinese hybrid socket according to the source. A plug with round pins, or a flat three-pin shape from another country, needs an adapter.
Then read the small print on the charger. A label such as “100-240 V” means the charger accepts 230 V. If it says “110 V” only, it is not made for China’s supply, and plugging it in is a risk to the charger.
A note for Australian and New Zealand travellers
The source says Chinese type I sockets put the earth contact at the top, while Australian and New Zealand sockets put it at the bottom. The plugs look alike, but do not assume your plug fits every Chinese outlet. Try it in the hotel before you rely on it, and carry an adapter.
A short packing list
- One universal adapter that lists China or type A and I.
- A power strip or a multi-port USB charger, so one adapter charges several devices.
- A short cable for the bedside socket.
