All Voltaic solar panels, solar chargers, and battery packs are TSA approved for both domestic and international flights. For specific packing/traveling instructions, including how to properly fly with a lithium battery - read below.
Can I check my Voltaic battery?
No. Since Voltaic's lithium batteries are used to charge other electronics they are considered "spare batteries". TSA mandates that all spare batteries be stowed in your carry-on (hand) luggage. Spare batteries CANNOT be packed in checked luggage under any circumstance. Read the TSA's guidelines on power banks.
Is there a limit to how many batteries I can carry on?
For domestic flights there is no limit to the number of spare battery packs each passenger can carry on a plane if the individual battery is less than 100 Watt-hours. This applies to all Voltaic batteries.

Do I have to remove my battery from my carry on bag when I go through security (just like my laptop)?
No. Lithium batteries, like your smartphone, do not need to be removed from your bag during security scans.
What can I check?
Personal electronic devices that have an embedded battery (phone, tablet, camera, laptop, etc.) can all be packed in your checked or carry-on luggage. Individual solar panels and accessories may also be packed as part of your checked luggage.
Are regulations on international flights different than domestic USA flights?
Yes, each country has their own flight regulations and some are more strict than USA's policy. As a general rule of thumb when traveling internationally, pack a maximum of 2 spare batteries in your carry on bag per passenger. Under no circumstance should you pack any spare battery packs in your checked luggage.
Some international security checkpoints will confiscate or ask you to mail any additional batteries over the limit of 2 batteries per passenger. For more information, please consult the regulations of the country you are traveling to or from.
