Bought 12/2020 and have extensively traveled with it in Europe, Asia, Africa, South America. I use for charging I Phone, Nikon and GoPro camera batteries, mini light. Powerful enough to keep you going before you find a dedicated power source. The pass thru charge feature and USB A and C makes this a perfect travel power bank. At 10000mah and it is small and light enough that most airlines and countries should allow. Always and check with your carrier and country first. I highly recommend this and other Aukley products.
