The Only Power Bank China Customs Won’t Take From You
I had a power bank confiscated at a Chinese airport. Not because it was too large — it was well under the 100Wh limit. They took it because it had no 3C certification mark. China’s airports now require this mark to be physically visible on the device. No mark, no board. The Baseus has it printed on both the unit and the box. It is the only power bank I travel to Asia with now.

⚠ What Happened to Me at Chinese Customs
I was travelling through China with a standard 20,000mAh power bank. It had the capacity clearly printed, it was within the 100Wh limit, I had used it on dozens of flights without issue. At the security checkpoint, the officer flagged it immediately. No 3C certification mark. Confiscated on the spot, no appeal, no receipt.
Since June 2025, China’s Civil Aviation Administration (CAAC) has made 3C certification mandatory for all power banks on Chinese flights. The mark must be physically visible on the device itself. Not just on the box. Not just in the manual. On the unit. Brands like Anker sold globally often skip this certification for their export versions. Chinese brands like Baseus target the domestic market and include it as standard.
Why You Need a Power Bank on Every Asia Trip
DMZ & Long Days Out
A full DMZ day — bus, tour, Dora Observatory — takes 8+ hours. Your phone camera and map navigation drain fast. 20,000mAh means you never miss the shot.
Navigation All Day
Google Maps running continuously in Korea, Hong Kong, or Japan eats a full battery by early afternoon. A power bank means you never navigate blind.
Airports & Long Flights
Asian airports are large and layovers are long. Incheon alone is a 2km walk between terminals. Plug access is scarce. This covers a full long-haul flight with charge to spare.
China Compliant
The only country where this matters at security. If China is on your itinerary — even as a transit — you need the 3C mark or you will lose the battery at the checkpoint.
Never Lose Your Battery to Customs Again
3C certified. Fast charge. Built-in cables. The one power bank that works everywhere — including China.
