Charging Your Phone on China High-Speed Trains

You can reliably charge your phone on almost all Chinese high-speed trains (G and D series). Power outlets are typically located under the seat, between the leg rests, or on the armrests depending on the class of travel, while newer Fuxing models also provide USB-A and sometimes USB-C ports. Keeping your device powered is essential for navigating China's digital-first landscape, from scanning QR codes for tickets to using see plans to stay connected during long journeys.

Understanding the Train Models

China's high-speed rail network primarily consists of two types of trains: the older Hexie (Harmony) models and the newer, state-of-the-art Fuxing (Rejuvenation) models. The availability of charging ports depends significantly on which one you board.

Fuxing Hao (CR400 Series)

These are the newest trains, often seen on the Beijing-Shanghai or Beijing-Guangzhou routes. They are a traveler’s dream for connectivity. In a Fuxing train, you will find power outlets for every single seat, regardless of the class. Most of these outlets are located on the front of the seat cushion (between your legs) or under the seat. Newer Fuxing models have added USB ports right next to the standard 220V plug, allowing you to charge your phone and a laptop simultaneously.

Hexie Hao (CRH Series)

The older Hexie trains are still very common. In Second Class, power outlets are more sparse. You might find one outlet for a row of three seats, usually located near the floor. In First and Business Class, outlets are guaranteed for every seat. If you are traveling between smaller cities, such as on a trip to see the Datong Guide: Hanging Temple and Yungang Grottoes, you may encounter these older models more frequently.

Charging Availability by Travel Class

Class of Travel	Power Outlet Location	USB Port Availability
Business Class	Side console or armrest; 1 per seat	High (Includes wireless charging on new models)
First Class	Armrest or under-seat; 1 per seat	Moderate (Common in Fuxing models)
Second Class	Under-seat or between leg rests; 1 per row or seat	Low to Moderate (Model dependent)

Second Class Strategy

In Second Class, the outlet is often shared. If you are in a row of three (seats A, B, C), the outlet is usually located under the middle seat (B). It is polite to ask your seatmates before plugging in, though most Chinese travelers are happy to share. If you find yourself on a very old CRH model without seat outlets, check the ends of the carriage near the sinks or the dining car, where public outlets are sometimes available.

Staying Connected on the Move

A full battery is only half the battle. As you speed through the countryside at 300 km/h, you need a data connection that works. Standard UK roaming from providers like EE, Vodafone, or O2 can be prohibitively expensive, often costing 6 to 8 per day for a tiny amount of data that is still subject to the Great Firewall. This means your Instagram, WhatsApp, and Google Maps won't work without a slow, battery-draining VPN.

ChinaRoam provides a superior alternative. By routing data outside the Great Firewall, a ChinaRoam eSIM allows you to use your favorite apps natively. Whether you are checking the opening hours for The Master of the Nets Garden in Suzhou Guide or navigating the Beijing subway, you get uncensored access on China Mobile, China Unicom, and China Telecom’s 5G networks.

Technical Requirements for Charging

China uses a standard voltage of 220V, 50Hz. This is compatible with UK and European devices, but travelers from North America (110V) must ensure their chargers are "dual voltage" (110V-240V).

Plug Types

Chinese outlets are usually "universal," meaning they accept:

• Type A: Two flat parallel pins (US style).
• Type C: Two round pins (Euro style).
• Type I: Three flat pins in a V-shape (Australian style).

British Type G (three square pins) plugs will not fit. You will need a simple travel adapter. Most Chinese high-speed train outlets are designed to take both the two-pin and three-pin (Type I) plugs simultaneously.

Network Coverage: Cities vs. Rural Rail

China has the world's most extensive 5G network. On major high-speed lines, you will enjoy consistent 5G or 4G+ coverage even in the middle of the countryside. ChinaRoam plans utilize all three major carriers—China Mobile, China Unicom, and China Telecom—to ensure you stay connected.

However, high-speed trains pass through many tunnels, especially in mountainous provinces like Fujian or Yunnan. During these segments, even the best signal will drop for a few seconds. If you are on a long-haul journey, it is wise to download your maps or entertainment beforehand.

Choosing the Right Data Plan

Before you board, see plans that fit your itinerary. ChinaRoam offers a variety of options:

• Fixed Plans: Range from 1GB for short 7-day trips to 50GB for long-term travelers (up to 180 days).
• Daily Passes: If you are a heavy user who streams video on the train, daily passes offering 1GB, 2GB, 3GB, 5GB, or even 10GB per day are available.

These are data-only plans, meaning they do not come with a local Chinese phone number. While this means you cannot receive traditional SMS, it is perfect for WhatsApp calls, FaceTime, and WeChat, which all function flawlessly on these networks.

How to Install Your eSIM

You should set up your eSIM before you reach the train station. First, check if your phone is compatible with eSIM technology. Most iPhones (XS and newer) and modern Android devices are ready.

Step-by-Step Installation

1. Purchase: Select your plan on ChinaRoam.
2. QR Code: You will receive a QR code via email.
3. iPhone: Go to Settings > Mobile Data > Add eSIM. Scan the code.
4. Android: Go to Settings > Network & Internet > SIMs > Add More > Download a SIM instead. Scan the code.
5. Activation: Follow the installation guide to set the ChinaRoam eSIM as your secondary data line. Ensure "Data Roaming" is turned ON for the eSIM.

Power Bank Regulations

While trains are lenient, if you are connecting from a flight, remember China's strict power bank rules. You are generally allowed to carry power banks with a capacity of up to 100Wh (about 27,000mAh). The capacity must be clearly printed on the device. If the label is worn off, security at both airports and some high-speed train stations may confiscate it.

The bottom line

Charging your phone on a China high-speed train is straightforward, especially on the newer Fuxing models where every seat has a dedicated outlet. To make the most of your journey, pair that full battery with a ChinaRoam eSIM. You'll avoid the high costs of UK roaming and bypass the Great Firewall, giving you the freedom to share your travel photos and navigate China with ease.
