Solar power has been around for ages, but there’s still something very cool about harnessing the power of the sun to keep our various less-powerful gadgets and lamps and televisions in working order. It’s the sun! People used to think that thing was a god and now we use it to juice up our Nintendo DSes. You got played, sun.

In any case, solar power is here to stay, as are solar chargers, those on-the-go battery backs for your phone or tablet that garner energy from sunlight. Meaning you’ll never have to plug it in as long as our little blue planet revolves around the sun.

Here are five portable, sturdy solar chargers that’ll keep you powered up as long as there is a sun in the sky.

5. iSunshineTech 15W Foldable Solar Charger with Dual USB Port

A foldable, well-powered solar panel that can charge two devices at once! At less than $50, that’s a pretty great steal for something that could save your life in a 127 Hours-style situation (or just your standard phone-died-need-Google-Maps situation). [Amazon, 42.49]

4. Dizaul Solar Charger, 5000mAh

This thing can withstand just about any kind of indignity you could imagine inflicting on it: drops in puddles, being left out in the rain, being tossed around in your backpack for months on end. The Dizaul handles it all and will still give your phone a full charge when you’re on-the-go. [Amazon, 19.95]

3. PLOCHY Solar Charger 24000mAh Portable Charger

The Plochy has enough internal storage to charge your iPhone ten times over if that’s what you need. Perfect for camping trips or when you’re sleeping over at your significant other’s place that seems to have zero fucking outlets. [Amazon, 39.99]

2. Anker PowerPort 21W Dual USB Solar Charger

The solar PowerPort is a great way to deliver a fast, sustained charge to your devices without spending even a minute inside. It delivers a charge at the speed of the regular wall outlet in direct sunlight, which is pretty damn nuts if you ask me. [Amazon, 61.99]

1. Hiluckey 10000mAh Waterproof Solar Power Bank

People love the Hiluckey’s amazing battery capacity at its price point, not to mention is a combination of a rugged, compact design and the fold-out fan design that gives you the best of both worlds when choosing the solar charger right for you. [Amazon, $27.99]

Last week SpaceX pulled off yet another historic flight by launching and recovering one of its Falcon 9 rockets for a record-breaking third time. But the celebration was particularly short-lived: Days later, a subsequent mission went amiss after the first stage of another Falcon 9 splashed down in the Atlantic Ocean after missing the landing pad at the Kennedy Air Force Base in Florida.

On Monday, scientists revealed the first images of a human inside the world’s newest total body scanner, called EXPLORER. The name is fitting because this scanner really leaves absolutely nothing to the imagination, tracking the way drugs and disease progress through every nook and cranny in the body.

Designed by biomedical engineering professor Simon Cherry, Ph.D., and biophysicist Ramsey Badawi, Ph.D. at University of California, Davis, this scanner produces images that look like a hybrid between a PET scan (which is often used to find tumors) and an X-ray, all in ghostly black and white. But what’s interesting about EXPLORER, which will be officially unveiled at the Radiological Society of North America meeting on November 24th, isn’t that it produces detailed images of tissues or bones. Cherry tells Inverse that it can also create 3D movies showing where certain drugs may end up in the body.

We’ve all been there: you’re out and your battery is at 5%. You’re frantically looking for an outlet for your phone in a crowded restaurant or train station. Your phone is like an extension of you so being without it isn’t just annoying, it can be crippling.

The BentoStack Charge is maybe the best solution to the battery life problem. It’s a wireless charger with both an easy to carry lid that charges your phone, and it comes with a storage box to carry a USB charger and even your wireless earbuds.

The internet is the perfect built-in audience for people with time on their hands, the desire to push limits, and new technology to play with. Take the case of this Tesla Model 3 owner, who recently decided to test exactly how much of a charge his car gets out if Tesla’s regenerative braking feature, and he very fortunately caught the whole thing on tape.
