We designed a suitcase that incorporate a high capacity (18,000 mAh) wireless charging power bank which is enough to recharge an average phone 8-10 times. In addition to wireless charging, users can use cords from the two traditional USB ports. It's super convenient to simply rest a phone on top of the suitcase to begin charging. No fumbling for cords or portable battery packs. No searching for vacant outlets or hovering near charging stations waiting for a turn. We started off by designing an incredibly well made suitcase without compromises. Some of the features include: Standard 22"h x 14"w x 9"d carry-on size. 100% polycarbonate shell. Polycarbonate is incredibly durable and much lighter weight than less expensive ABS plastic. We've Integrated TSA locks directly into the suitcase so there are no more locks to lose. Zippers are incredibly important so we spared no expense and are adding Waterproof smooth glide zippers. Aluminum trolly handles are very durable and lightweight and a perfect compliment to our overall design.Of course you want a suitcase that is easy to maneuver. We opted for quad spinner wheels made with polyurethane for silent rolling. Each corner has double wheels for added stability.
