Travelers who rely on ultralight, compact power banks may want to pay close attention if China is on the itinerary. Nitecore is expected to begin rolling out power banks carrying China’s required China Compulsory Certificate (CCC) mark as early as next month, a move that could make life much easier for frequent flyers navigating strict airport battery rules.
A Singapore retailer focused on Nitecore gear reports that the first CCC-marked Nitecore power banks should arrive in June. The CCC symbol, sometimes called “3C” or “Triple C,” is easy to spot once you know what to look for: three letter Cs inside an oval. This small logo matters because power banks without it are not permitted on domestic flights within China. Some airlines have clearly stated that non-compliant units can be stopped at security and even confiscated before passengers reach the gate.
Battery checks are already more intense in many parts of East and Southeast Asia compared to what travelers might be used to in Europe. Security staff may look closely at battery labeling, including capacity, and airports and airlines often post guides showing how to convert confusing milliamp-hour (mAh) ratings into watt-hours (Wh). China adds another layer of scrutiny: if a power bank lacks the CCC mark, it can become a problem immediately at screening for domestic travel.
The situation is particularly notable because Nitecore is owned by Sysmax, a China-based company, yet many of its power banks have historically been sold without CCC certification. One likely reason is that certification can take time, and brands may choose to launch products in other markets first while approvals are still in progress. In practice, plenty of manufacturers either don’t sell CCC-marked models widely or don’t highlight the certification in retail listings, which makes it harder for shoppers to know what they’re getting.
For anyone planning a trip that includes domestic flights in China, the safest approach is to research power bank rules in advance and verify compliance before buying. If you’re shopping in-store, check the packaging and the product label carefully. If you’re purchasing online, be cautious with vague specifications and consider confirming how the CCC mark will be shown on the exact unit you’ll receive.
It will also be worth watching how Nitecore handles its upcoming CCC-marked batches of already announced power banks. Clear visual differences could be important, especially since retailers outside China may not be fully aware of how strict the CCC requirement is for travelers. A simple design tweak, a new label placement, or updated packaging could help buyers avoid accidentally picking up the wrong version.
The tightening focus on power banks comes amid broader airline safety concerns. Attention increased after an incident involving Air Busan Flight 391 in early 2025, when an aircraft caught fire on the ground in Busan. While the final report has not been released, the fire was believed to have started in overhead luggage compartments. Since then, many airlines—including some in Europe—have restricted the use of power banks during flights, and passengers are often instructed to keep them within easy reach rather than stored overhead.
Some countries have gone even further with additional precautions. In South Korea, for example, exposed battery terminals may need to be insulated (such as with electrical tape) before passing through security. Safety statistics from South Korea also suggest power banks are involved in in-flight incidents more often than smartphones, with low-quality products potentially playing a significant role. At the same time, it’s important to interpret those numbers carefully: nearly everyone carries a phone, while fewer travelers carry power banks, and usage patterns differ.
Bottom line: if you want a lightweight travel power bank that won’t trigger headaches at airport security—especially for China domestic flights—the arrival of CCC-marked Nitecore models could be a meaningful change. Until they’re widely available and clearly labeled, verifying the CCC mark before you fly remains one of the smartest travel gear checks you can make.
