The race is on now for tech companies to deliver charging options that give portable devices an even greater range. After all, it’s hard to find a handy outlet or USB charging station when you’re forging your way up to a mountaintop or camping out in the deep woods.

The Solar JOOS Orange claims to be one of the most powerful and adaptable solar chargers of its kind. It’s got a durable, waterproof design and can squeeze juice out of lighting conditions ranging from broad daylight to low light and light rain.

It will fill your USB-connected device up with power 3.5 times faster than competing devices at the same price ($150). There’s also an onboard battery that you can pre-charge using the included USB connection, to store an extra helping of energy before you set out on a trip.
