Plugs, Sockets and Voltage in China 2026: What to Pack2026 中国插头、插座与电压：该带什么

1 The short answer: what plugs and voltage does China use? 一句话结论：中国用哪种插头和电压？

China runs on 220 volts at 50 hertz, and the sockets take three plug shapes: the two-flat-pin Type A, the two-round-pin Type C, and the three-flat-pin angled Type I. If your home uses Type A (North America, Japan) or Type C (most of Europe), your pins already fit many Chinese sockets. If you come from the UK, Ireland, Singapore or Hong Kong with Type G, or from Australia with Type I, you will want a small adapter.中国使用 220 伏、50 赫兹的电力，插座接受三种插头形状：两扁脚 A 型、两圆脚 C 型，以及三扁脚斜排的 I 型。如果你家乡用 A 型（北美、日本）或 C 型（欧洲大部），你的插头已经能插进很多中国插座。如果你来自英国、爱尔兰、新加坡、香港（G 型），或来自澳洲（I 型），你会需要一个小型转换头。

The good news is that almost every modern phone, laptop and camera charger is dual-voltage, so it works on 220V without a converter, and you only need a plug adapter to match the socket. This guide covers the plug types, the voltage rule, which gear is fine as is, what to pack, and how to charge on the move.好消息是：几乎每一台现代的手机、笔记本、相机充电器都是宽电压的，所以它在 220V 上无需变压器就能工作，你只需要一个插头转换器去配插座。本指南会讲插头类型、电压规则、哪些设备原样可用、该带什么，以及怎么在路上充电。

Before you pack, check your own devices with our free plug and voltage checker插头与电压核对工具, which tells you exactly what each gadget needs for China.打包前，先用我们的免费「插头与电压核对工具」核对你自己的设备，它会精确告诉你每件小电器在中国需要什么。

2 The three plug types you will meet 你会遇到的三种插头

Type A is the flat two-pin plug common across North America and Japan, and you will find it fits many Chinese sockets directly. Type C is the round two-pin plug used across Europe, and it also drops into the mixed sockets found in hotels and newer buildings. Type I is the three-flat-pin plug used in Australia, New Zealand and parts of China itself, including Hong Kong and some mainland outlets.A 型是北美和日本常见的两扁脚插头，你会发现它能直接插进很多中国插座。C 型是欧洲通行的两圆脚插头，也能插进酒店和较新建筑里常见的「混合插座」。I 型是澳洲、新西兰以及中国部分地区（含香港和一部分内地插座）使用的三扁脚插头。

In practice, the easiest move is a small universal adapter that covers A, C and I, plus a couple of USB ports so you can charge several devices from one wall point. Newer Chinese hotels often have USB ports built into the wall or the desk, which means you may only need a cable, not an adapter, for phones.实际最省事的做法，是一个能覆盖 A、C、I 的小型万能转换头，外加几个 USB 口，这样你一个墙插就能给多台设备充电。较新的中国酒店常把 USB 口直接做在墙上面板或书桌里，意味着手机可能只需一根线、而非转换头。

• Type A.A 型。 Flat two-pin, fits many Chinese sockets directly.
• Type C.C 型。 Round two-pin, common in European gear.
• Type I.I 型。 Three flat pins, used in Australia and parts of China.

3 Voltage and frequency: 220V 50Hz, and what it means 电压与频率：220V 50Hz，意味着什么

China supplies 220 volts at 50 hertz, compared with 120V 60Hz in North America and 230V 50Hz across most of Europe. For your chargers this barely matters, because phones, laptops, tablets and camera batteries all charge through a brick that accepts a wide voltage range, usually printed as 100 to 240 volts. That brick happily runs on Chinese 220V with only a plug adapter.中国供电为 220 伏、50 赫兹，对比北美是 120 伏、60 赫兹，欧洲大部是 230 伏、50 赫兹。对你的充电器来说这几乎无所谓，因为手机、笔记本、平板和相机电池都通过一个「充电头」充电，而充电头接受很宽的电压范围，通常印着 100 到 240 伏。这种充电头只需一个插头转换器，就能愉快地跑在中国 220 伏上。

The device to watch is anything with a heating element or a motor built for one voltage, such as a hair dryer, straightener or electric kettle from a 120V country. Those are not safe on 220V with only an adapter, and they need a proper step-down converter or, simpler, a cheap local replacement bought in China.要留意的是任何带发热体或电机、且只为一档电压设计的设备，比如来自 120 伏国家的吹风机、直发夹、电热水壶。那些只靠转换头插在 220 伏上不安全，它们需要一个真正的降压变压器，或者更简单：在中国买个便宜的本地替代品。

Always read the tiny print on the charger before you plug in. If it says 100 to 240V, you are set with an adapter. If it says 120V only, do not use it on a Chinese socket without a converter.插电前，先看充电头上的小字。如果写着 100 到 240V，配个转换头就成了。如果只写 120V，没有变压器就别插进中国插座。

4 Which devices work, and which need a converter 哪些设备可用，哪些需要变压器

Safe with just an adapter: phones, laptops, tablets, e-readers, camera and drone batteries, electric toothbrushes and their chargers, and almost any wall brick marked 100 to 240V. These are dual-voltage by design and only need the pins to match the socket. Pack one adapter and you can charge the whole kit.只靠转换头就安全的：手机、笔记本、平板、电子书、相机和无人机电池、电动牙刷及其充电器，以及几乎所有标着 100 到 240V 的墙插充电头。这些天生宽电压，只需把插脚配上课插座就好。带一个转换头，你就能给整套装备充电。

Needs a converter or a local buy: single-voltage hair dryers, curling or straightening irons, and kettles brought from a 120V country. Rather than haul a heavy converter, most visitors just buy a hair dryer at a Chinese shop or use the one already in the hotel room. Hotel rooms in China almost always include a hair dryer in the bathroom.需要变压器或本地购买：只支持单一电压的吹风机、卷发棒或直发夹，以及从 120 伏国家带来的电热水壶。与其扛一个沉重的变压器，多数游客干脆在中国商店买个吹风机，或者直接用酒店房间里本来就有的那台。中国的酒店房间几乎总在浴室里备有吹风机。

• Adapter only.只要转换头。 Phones, laptops and camera kit are dual-voltage.
• Converter or buy.变压器或现买。 Single-voltage heaters from 120V countries.
• Use the room dryer.用房间里的。 Hotel bathrooms already have a hair dryer.

5 What to pack: adapters, and a quick check 该带什么：转换头，以及一次快速核对

Pack a small universal adapter that covers Type A, C and I, and bring two if you travel with a laptop and a phone that both need a wall point at once. Add a short multi-USB charger so a single adapter feeds several cables. Keep the adapter in your carry-on, not your checked bag, so you can charge at the airport or on a layover.带一个能覆盖 A、C、I 型的小型万能转换头；如果你同时需要给笔记本和手机占墙插，就带两个。再加一个多口 USB 充电头，这样一个转换头就能喂好几根线。把转换头放在随身包里、而非托运行李，这样你在机场或转机时也能充电。

Before you fly, run your devices through the free plug and voltage checker插头与电压核对工具 on this page. It lists each gadget's plug and voltage needs for China, so you know exactly what to pack and what to leave at home. A two minute check prevents a dead phone on day one.出发前，把你设备过一遍本页的免费「插头与电压核对工具」。它会列出每件小电器在中国需要的插头与电压，让你精确知道该带什么、什么可以留在家。两分钟的核对，能避免第一天手机就没电。

6 Buying adapters in China if you forget 忘了带，在中国怎么买转换头

If you arrive without an adapter, you are rarely stuck. Convenience stores in airports and big stations, electronics shops, and the small stalls in malls sell universal adapters, and so do the apps covered in our Taobao guide淘宝指南 for next-day delivery to your hotel. Prices are low and staff are used to travellers asking for a travel plug.如果你没带转换头就到了，也很少会卡住。机场和各大车站的便利店、电子用品店，以及商场里的小摊都卖万能转换头；我们的「淘宝指南」讲的那些 App 还能次日送到你酒店。价格很低，店员也习惯了旅客来问「旅行插头」。

For a same-day fix, ask the hotel front desk first. Many Chinese hotels keep a loaner adapter at the desk, or can point you to the nearest shop. Buying locally also means you get a plug that fits the exact socket in your room, which removes any guessing.要当天解决，先问酒店前台。很多中国酒店前台备有可借的转换头，或能指给你最近的店。本地买还意味着你拿到的是正好配你房间插座的插头，省去任何猜测。

For the payment side of a quick local buy, our how to pay guide中国支付指南 covers the scan-to-pay flow, and our card setup guide绑卡指南 gets your card ready before you land.关于临时本地购物的付款，我们的「中国支付指南」会讲扫码付款流程，我们的「绑卡指南」能让你落地前把卡准备好。

7 Charging on the move: power banks, trains and cafes 在路上充电：充电宝、火车与咖啡馆

A power bank is the simplest insurance against a dead phone while you are out all day. China is dense with places to top up: cafes, fast-food spots, trains and stations all have reachable sockets or USB ports, and your adapter from home covers the wall. Keep a bank in your day bag and you stop worrying about battery.充电宝是整天在外时、对抗手机没电最简单的保险。中国到处都能补电：咖啡馆、快餐店、火车和车站都有够得着的插座或 USB 口，你从家里带来的转换头就能插墙。在日用包里放一块充电宝，你就不用再操心电量。

On high-speed trains, every seat has a socket at the base, usually Type A or a mixed outlet, so laptops and phones charge en route. At airports, charging spots are common near gates. One reminder: power banks must go in your carry-on, never checked luggage, and under China's CAAC rules each bank must be 100Wh or less (about 27,000mAh) with a limit of two banks per passenger, so a standard 10,000 to 20,000 mAh bank is comfortably within the cap.高铁上，每个座位底部都有插座，通常是 A 型或混合口，所以笔记本和手机能在路上充电。机场里，登机口附近常见充电点。一个提醒：充电宝必须随身带、绝不托运；按中国民航局（CAAC）规定，每块不得超过 100 瓦时（约 27000 毫安时），且每位旅客最多带 2 块，所以标准的 10000 到 20000 毫安时完全在限额内。

• Carry a bank.带块充电宝。 Cheap insurance for a full day out.
• Trains have sockets.火车有插座。 Every seat base has a outlet on high-speed rail.
• Carry-on only.只能随身。 Power banks stay in hand luggage within the cap.
