It shouldn't just stop working :) **Q: Can I bring it on a plane? Is the product certified for it?** A: You can take this power bank on a plane. The cells within this power bank are lithium ion with a nominal voltage of 3.7V (5V is the output voltage at the USB port, not the voltage of the cells within the battery). Therefore the Wh rating for this power bank is 99.16Wh, below the limit. **Q: I have just received and am using the battery pack. I am wondering why output 3 is coloured orange, whilst output 2 is blue. Are they different?** A: Blue has higher power output **Q: Can you use all three input ports to recharge more quickly or must you only use one?** A: Hello my friend, even though this portable charger providing 3 different input ports to recharge itself, you can only choose one of them at one time. Thanks.
