One of the most stressful parts of leaving home is wondering if your laptop and smartphone will die when you need them most. LAER, a Bluetooth-enabled laptop sleeve currently raising money on Indiegogo, thinks it's the solution to that problem. The premise of the product is pretty simple — it claims it can charge your laptop (PC or Mac), smartphone, and tablet all at the same time. This way, you don't have to bring all of your chargers with you and attempt to find a plug wherever you're at.
