If it's not the most debated MacGuffin in cinematic history, it's certainly close.
Some say diamonds; others the Holy Grail; still others a small nuclear bomb, as an ode to classic noir Kiss Me Deadly.
But we were all wrong. It was definitely this:
The Kalisaya Portable Solar Generator, a portable, sun-powered generator that can store up to 11 hours of power for your assorted gadgets and e-things.
All it needs is sunlight to charge, and unlike other portable charging stations, the Kalisaya keeps all your handsomely items out of sight, so you can focus on the important things, like soaking up some rays yourself. The case and its standard lithium-ion battery and photovoltaic cell only weigh 14 pounds, and the rig packs enough punch to jump-start a car.
As long there's a cell signal, it will.
