DescriptionPut simply: Lifepack is the ultimate backpack. Packed with a solar-powered power bank, a Bluetooth speaker, an integrated lock, and many more features, Lifepack caters to the city-dwelling weekend warrior. This durable and weather-resistant backpack has multiple compartments for your laptop, smartphone, sunglasses, and many more personal items, but that's just the tip of the iceberg. It also has an interior USB power cable and an additional USB port so you can charge two devices simultaneously while enjoying your music from the integrated Bluetooth speaker — all while the bag itself recharges via the sun. Pretty incredible stuff.
