Are these two things allowed on the train to Shanghai during the World Expo?
May I tell you what mode of transportation to choose? If it's a train, it's ok, and so is a car, but if it's an airplane, the inspection will be stricter and you can't bring a knife. The second one is normal and does not limit any traffic. Because you use a small computer UPS instead of a large lead-acid battery of a certain specification. Don't worry.
