Your Power Bank Will Be Rejected. Unless You Read This First.

She was twenty minutes from boarding when the security officer stopped her. The power bank — a well-known international brand, fully charged, bought from an official retailer at home — was placed on the inspection table, examined for thirty seconds, and removed from her bag. No negotiation. No exceptions. No refund. A device she had carried through airports on four continents was rejected at a Chinese airport because it was missing three letters: C, C, C.

This is happening commonly across all 200+ civil airports in mainland China. Since June 28, 2025, the Civil Aviation Administration of China (CAAC) has strictly enforced a regulation banning any power bank without a visible CCC mark — China's mandatory safety certification — from all domestic flights. The rule catches foreign travelers off guard in disproportionate numbers, because the power banks most of us carry were made for export markets and do not carry the Chinese certification, even when the device itself was manufactured in China.

⚠️ The key fact most travelers miss: "Made in China" does not mean "certified for China." Some power banks produced for international markets are not required to carry the 3C mark — and without it, Chinese airport security will confiscate the device regardless of brand, price, or country of purchase.

This guide explains what 3C certification is, how to check whether your power bank has it, what to expect at Chinese airports, and exactly where to buy a compliant replacement if you need one. Read it before you pack.

What Is 3C Certification — and Why Does China Require It?

CCC stands for China Compulsory Certification — in Chinese, 中国强制认证. It is the Chinese equivalent of the CE mark in Europe or the UL mark in the United States: a government-mandated safety standard that electronic products must meet before they can legally be sold in China. For power banks specifically, the certification was introduced in August 2023 and became mandatory for all products sold domestically from August 1, 2024.

The regulation was a direct response to a safety crisis. CAAC recorded seventeen thermal incidents involving lithium batteries on domestic flights in 2023 alone, including a case where smoke from a passenger's uncertified power bank forced a flight to return to its departure airport. The authorities determined that a significant proportion of these incidents involved devices that had not been independently tested for safety — products that might perform adequately under normal conditions but posed unacceptable risks at altitude, in pressurized cabins, with multiple devices charging simultaneously.

The 3C mark is an oval logo containing three overlapping capital letter "C"s. It must be physically printed or engraved on the power bank's casing — not just on the packaging, the manual, or a removable sticker. If the mark is faded, blurry, or absent from the device body itself, Chinese airport security is authorized to treat the device as non-compliant.

Think of it this way: the CE mark on your power bank means it passed European safety standards. The 3C mark means it passed China's — and in Chinese airports, only one of those marks counts.

Run These Three Checks on Your Power Bank

1. Find the 3C / CCC mark on the device body. Look for an oval logo with three overlapping "C"s, physically printed or engraved on the power bank casing — not on the box, not on a sticker that can be removed. Do not confuse it with the CE mark (European standard), which Chinese security will not accept as a substitute.

2. Confirm the capacity in Wh is clearly printed. Chinese regulations require the watt-hour (Wh) rating to be legibly displayed on the device. If your power bank only shows mAh (milliamp hours) without the Wh conversion, or if the label is blurred or damaged, security may flag it. The calculation: Wh = mAh ÷ 1000 × voltage (usually 3.7V). A 20,000mAh bank is typically around 74Wh — well within the 100Wh carry-on limit.

3. Check for recalls if you have a Chinese-market device. In mid-2025, several major brands — including certain Anker, Xiaomi, Baseus, and ROMOSS models — had their 3C certification suspended due to issues with battery cells from a specific supplier. If your power bank was purchased in China before August 2025, verify your model number against current recall lists on the brand's official website before flying.

Common mistake: Many travelers assume that buying a big-name brand guarantees compliance. It does not. Anker, Belkin, RAVPower, and other internationally recognised brands sell different product lines for different markets. The version sold in the UK, US, or Australia was manufactured for those markets and does not carry the 3C mark — even if the physical device is identical to a 3C-certified Chinese-market version.

What Happens at Chinese Airport Security — and What to Expect

At security checkpoints in Chinese airports, officers will ask you to remove your power bank from your bag and place it separately for inspection — the same procedure as for laptops. A dedicated inspection step has been added at most airports: the officer will physically examine the device for the 3C mark, check that the capacity labelling is clear, and assess the device's general condition. A blurred label, missing Wh rating, visible damage, or absent 3C mark will result in confiscation. The process takes seconds and there is no appeals procedure at the checkpoint.

In the vast majority of cases, confiscated devices are not returned. Some larger airports offer temporary storage services where you can leave an item and collect it on your return — but these services are rare, inconsistently available, and not offered at all airports. Treat confiscation as permanent.

✓ The rule applies only to flights. Outside of airports, there is no restriction on using uncertified power banks anywhere in China — hotels, restaurants, trains, tourist sites, and public spaces all remain completely unrestricted. If you are not taking domestic flights, your existing power bank poses no problem.

✓ International arrival flights are generally exempt. If you fly directly from overseas to a Chinese city and do not connect to a domestic flight, the rule does not technically apply to your inbound journey. The enforcement begins when you board a domestic Chinese flight — including connections.

Several travelers have also reported their power banks being checked on international departures from Chinese airports, particularly in Shanghai and Beijing. While the regulation officially covers domestic flights only, enforcement practice has been inconsistent, and it is safest to assume the rule applies to any flight departing mainland China.

Lost Your Power Bank — or Arriving Without One? Here's Exactly Where to Get a Certified Replacement

The good news: China is where power banks are made, and buying a certified one once you land is straightforward and inexpensive. You do not need to search hard or speak Mandarin. Certified devices from reputable brands are available in every major city at the following locations.

Xiaomi Most recommended

The most reliable choice for travelers. Xiaomi stores are found in every major city and most airports. Their standard 10,000mAh and 20,000mAh power banks are 3C certified, clearly labelled, and priced at ¥79–¥199. Fast charging models available.

Baseus Best value

A popular Chinese brand available at most electronics retailers and on JD.com. Mid-range pricing (¥99–¥249) with reliable 3C certification. The Bowie 20000mAh model is a traveler favourite with dual USB-C output.

UGREEN Premium option

Higher-end specifications including GaN fast charging. Widely available in electronics stores and on JD.com. Prices from ¥159–¥399. Excellent build quality and clearly printed certification marking.

Anker (CN) Check model number

Anker sells 3C-certified models in China under the Anker Zolo line. Verify the specific model number before purchasing — not all Anker products sold in China carry current certification. Available at JD.com and Anker's Tmall store.

Yoobao Budget pick

Entry-level certified option, widely available at convenience stores (7-Eleven, Lawson, FamilyMart) across major cities. Basic functionality at ¥49–¥99. Ideal if you need something immediately and plan to travel light.

Huawei / OPPO Flagship stores

Both brands sell proprietary power banks at their retail stores, all 3C certified. Premium prices (¥199–¥499) but top-tier quality. Available in every major city; flagship stores in shopping malls often have English-speaking staff.

One Small Check. One Less Problem. More Time to Enjoy China.

China's 3C certification rule is not designed to inconvenience tourists. It was introduced because uncertified lithium batteries represent a genuine and documented safety risk on aircraft, and because the Chinese market had been flooded with products that lacked basic quality controls. The travelers who get caught are almost always caught by surprise — not because they were careless, but because nobody told them this rule existed before they packed.

Now you know. The check takes thirty seconds: find the 3C mark on the device body, confirm the Wh rating is clearly printed, and verify your model isn't subject to a recall. If your power bank passes, pack it with confidence. If it doesn't, a certified replacement is available in every Chinese city for under ¥200 — often less than the taxi from the airport.

China's cities are among the most rewarding travel destinations on earth, and keeping your devices charged is non-negotiable when you're navigating with apps, translating menus, and documenting everything you find. The 3C rule is a five-minute problem with a straightforward solution. Don't let it be the thing you remember most about your trip.
