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. And it simplifies the need for multiple portable chargers for those of us with a lot of devices.

The group behind the Indiegogo campaign, London-based ARROE, says it will also release an app to let you track how how much of LAER's battery is left and where the device itself is actually located.

LAER (pronounced "layer") will include DC charging for PC and Mac computers, USB-C charging, USB Quick Charge, and QI wireless charging.

If it works as advertised, the sleeve would let you charge at least three personal devices at the same time. You could keep adding more after that, but ARROE says the battery would drain more quickly.

The Quick Charge option would let you charge your device from 0 percent to 50 percent in just half an hour, ARROE claimed.

LAER would also let you swap out batteries, giving you the power to decide how much weight you want to carry around depending on how much power you'll be needing. You can choose either the 5,000 mAh battery or go all out with the 20,000 mAh battery for big work days. The batteries will be designed to last for about two years before needing a replacement.

The featured early bird deal will set interested buyers up with the LAER sleeve and a 5,000 mAh battery for $100. If everything goes according to plan, the product is expected to ship to backers by March of 2018.
