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 Automated Tea Machine Brews Tea Bags and Loose Leaves With the Convenience of a Keurig

BRÜ
BRÜ

The convenience of Keurigs has changed the way people get their morning coffee, but for tea drinkers, the options have been far more limited. Though companies have released their teas in K-cup pods, you’re usually beholden to a more limited selection in terms of flavor variety and leaf type. The BRÜ is looking to change that by giving tea drinkers an automated brewing machine that allows for full customization, like temperature control, cup size, and the option to actually choose from your favorite loose-leaf teas and bags. With more than $180,000 in pledges raised already, the BRÜ has shattered its $30,000 goal on Kickstarter. But you can still get your own machine for just $95 by heading here before the campaign ends on November 1.

The BRÜ looks just like a Keurig in many ways—there’s the water tank, the familiar spout, and the drip tray. But with this machine, you're in control of far more. If you want a small cup of strong, bagged green tea, it's just a few button presses away. If your friend then wants a weaker glass of loose-leaf white tea that's not too hot, it can be ready in minutes, all without the hassle of dealing with a traditional kettle. With its stretch goals already reached, the company is even working on a setting for cold tea, which will brew a small but concentrated cup of hot tea, then dispense chilled water on top of it.

If you act fast (like fast, fast) you can still score the $95 BRÜ package, along with a glass mug. The next tier starts at $115 and includes a similar haul, but this time it’s for the BRÜ+ machine, which the company says dispenses the water in a way that actually cleans the tea chamber after each cup.

The BRÜ won’t be available for the holidays, so if you’re looking to give it as a gift this Christmas, you’ll receive a gift card voucher. Orders are expected to start going out for delivery in April 2020. For more information, head to the BRÜ Kickstarter page, where you can become a backer until November 1.
