This Self-Warming Mug Doubles as a Wireless Phone Charger

Today in things you never knew you needed: There’s now a coffee mug that can fuel you and your phone. At its most basic function, the new KOPI Mug can brew coffee or tea directly into your cup and warm up your beverage after it's cooled off. What really sets it apart, though, is the fact that the coaster it rests on can also double as a portable, wireless phone charger.

This “self-warming brew system” is the brainchild of TWINZ Studio, a design company that has previously released other eco-friendly products, including titanium straws and chopsticks.

The KOPI Mug is designed to keep your beverage at an optimal temperature of 130°F for at least an hour and a half. A lid is also provided to help seal in the heat, making your coffee last as long as possible. The mug itself is made of porcelain ceramic, which heats up via electromagnetic energy when the metallic particles in the base of the mug come into contact with the charging coaster.

This same technology is what allows the coaster to double as a phone charger. “Since the unit does not actually heat up, [instead] providing an electric charge to heat the inlaid materials within the mug, it will remain cool to the touch, allowing your phone to be placed on top without risk of damage,” the company writes in its Kickstarter campaign.

It’s also ideal for those who only drink one or two cups of coffee in the morning. Instead of wasting a filter on a small amount of coffee, the company offers reusable coffee and tea filters that attach to the mug, letting your beverage of choice be brewed directly into your cup.

Get the KOPI Mug and wireless charger on Kickstarter for $60. Different combination packs with filters, a titanium stir stick, a glass measuring pitcher, and a coffee canister are also available.

This Portable Mini Movie Projector Aims to Bring HD Quality to Nearly Any Surface

Forget about streaming your favorite show or movie on a tiny smartphone or laptop screen, because this new mini projector from Formovie Technology Inc. looks to bring the at-home viewing experience on the go.

The Formovie Dice 1080p portable projector (available here) is able to display crisp and clear images in a variety of sizes and on surfaces beyond flat white screens. This makes it a great option for enjoying films out on the deck, on your living room wall, or projected onto the side of a tent during a camping trip. You can also adjust the image from your remote, so if you have to project the movie at an angle, you'll be able to straighten out the picture without having to manually move a lens. The projector will even sense the distance between itself and the surface and automatically focus the image depending on its location.

The Dice is fully immersed in Google's ecosystem and comes equipped with Android TV, Google Assistant, and a Chromecast built right into it, meaning it's all controllable from your smartphone or through voice commands. The projector also features HDMI and USB jacks, as well as Bluetooth capabilities, so you can still watch even if you're not near Wi-Fi.

The built-in battery lasts up to three hours on a single charge, and the company guarantees that the projector will last for 30,000 hours, which they say is equivalent to watching movies for eight hours a day for a decade.

With $43,221 raised on Indiegogo, Formovie already surpassed its original campaign goal of $1000. But you can still help bring the project to life starting at $499 (a 23 percent discount) by heading here.

Confuse Your Friends With an Upside Down Wine Glass

Sometimes the best pranks are the ones that take the least amount of work. And this one is as simple as drinking a glass of wine—upside down.

The Upside Down Wine Glass is available on Amazon for $15. And unlike traditional glasses, you pour your vino into the stem, creating the illusion that you're drinking from the bottom and about to spill the glass’s contents everywhere (the prank is probably best pulled when you're drinking red wine and sitting on a friend's new white couch).

Alongside looking cool, this 11-inch glass can hold up to 25 ounces of wine (a 750 ml bottle) at once. And while definitely a conversation starter, there's no word on how it affects the taste and general drinking experience.
