A: Hi, thanks for reaching out about 10000mAh Power Bank w/ USB- C Cable - Black - heyday™ Black. Can this Power Bank be used in China? Yes, the power bank is compliant with international flight capacity rules, but you must be aware of Chinese aviation regulations, especially the new 3C certification rule. Capacity (The Good News) 10,000 mAh is well below the capacity limit for air travel. The international and Chinese limit for power banks without special airline approval is 100 Wh. Your device is safe under this limit. Air Travel Regulations in China (The Caution) When flying within or out of China, you must follow strict rules: Carry-On Only: Power banks are never allowed in checked luggage. They must be in your carry-on bag. Visible Labeling: The capacity (ideally in Wh, or mAh and Voltage) must be clearly printed on the device. If the label is worn or missing, security will likely confiscate it. The 3C Certification Rule (The Potential Problem): As of June 2025 (and enforced rigorously in some locations earlier), all power banks carried on domestic Chinese flights (and sometimes international flights departing China) must have the China Compulsory Certification (3C) mark. Since the heyday power bank is a US-market brand, it is very unlikely to have the Chinese 3C mark. Recommendation: If you plan on taking any domestic flights within China, you should be prepared to have this power bank confiscated, or consider buying a 3C-certified one after you arrive. For international flights into China, this rule is less likely to be enforced, but it can still happen. 2. Does this work with iPhones? Yes, this power bank will charge any iPhone. The power bank is advertised as having a USB-C port and a USB-A port, which are standard charging outputs. For newer iPhones (iPhone 15 series): You can use the included USB-C cable to connect directly to the iPhone's USB-C port for fast charging. For older iPhones (iPhone 14 series and older): You will need your own USB-A to Lightning cable or a USB-C to Lightning cable to connect your iPhone to the power bank.
