Solartab 5.5-watt solar charger

It’s a problem when you get caught away from home with a dead phone. And it’s a bigger problem when you find yourself stranded with a dead phone and a flatlined portable charger. But one company has come up with a solution to both of those problems.

Solartab is a power source with a massive capacity and a handy ability: It draws energy from the sun like Superman. It can hold an impressive 13,000 mAh, which is enough to recharge an iPad Air 2 twice or an iPhone more than five times, depending on your model. And the best part is that all of this power is basically free.

The worst part, though, is that the Solartab is massive.

Lust List: Ribbn car charger by Tylt

Simple, elegant and fun, the Ribbn car charger is no-muss, no-fuss.

Offering up 4.8 amps, Tylt’s little Lightning charger plugs into a standard cigarette lighter socket and adds a bit of bright-blue bling to your car’s interior.

LAS VEGAS — Companies are throwing sensors into everything this year. Toothbrushes, cookie jars, mouth guards … you name it, and someone is trying to cram some sort of sensor into it. Next up is your backpack.

AMPL Labs’ upcoming SmartBackpack promises to keep your tech items safe and charged for days by combining “smartsensors” with battery packs woven into the fabric. The end result is a supercharging backpack that can tackle anything from an iPhone to a MacBook, allowing wearers to charge multiple devices on the go.

“We found that 85 percent of consumers worry about their devices running out of power at least once a week,” said AMPL’s David Migdal. “So we developed our SmartBackpack to address all their power needs.”

Travel can be a chance to practice minimalism, or an opportunity to drive yourself nuts. What am I talking about? Luggage. You can pare down your essentials to fit in a carry-on – even if you’re away for a month – or you can throw in every item of clothing and every charger you have. The second approach will result in a broken back, and you’ll still find that you left something essential at home.

Over the years, I’ve perfected my packing technique so that I only take the bare minimum. And when I say “perfected,” I mean “struggled with.” But it works for me, and the principles can be applied even if you’re the kind of person who hires a boy to carry your trunks for you when you take a cruise on the Titanic.

So here’s the Cult of Mac Guide to Traveling Light, a roundup of strategies, product recommendations and other tips to make your next trip a breeze.

Remember when the coolest brag for a gadget was that it was “credit card size”? Those times are back. The Revi Charger is a credit card-size iPhone charger with a built-in backup battery, and could really be just the thing in an emergency.

Sick of waiting for your iPhone to finish charging? By 2017, your iPhone could completely charge from 0% to 100% in just 5 minutes, in a portable, consumer-friendly package that will make long charging times a thing of the past.

The little BOLT Charger Battery is as clever as it is good looking. The USB wall-charger packs a backup battery into its tiny body, as body that leads its maker to call it the “The World’s Smallest Wall Charger + Battery Backup.”

I’m not sure how true that it, but who cares? It fits in your pocket and it’ll juice your iPhone twice, even without a wall to shove it into.

Ever “hefted” the standard North American iPhone charging cube in your hand and thought, “Boy, this thing would be way better if the prongs would fold up, and maybe if the thing could juice an iPad as well as my iPhone. And hey, why not make it black so I can lose it more easily too?”

Well, you’re not alone, because somebody at Scosche thought the exact same thing, and the superCUBE flip was born.

Wireless charging is a beautiful concept that fails to live up to its promise in reality. That’s not to say it’s unusable – far from it. I’d put wireless charging pads in the same place as Wi-Fi was some years back – useful when it works, but frustrating to get working properly.

The little iQi panel goes some way to fixing up the main problem of wireless charging on the iPhone. Because it’s not built in, you usually need a bulky case to pair with the charger itself. The iQi is so tiny it can be used with any case.
