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.

Make Your Own Ship in a Bottle With This LEGO Set

Building a ship in a bottle doesn’t need to be a stodgy affair—especially when you’re doing it with LEGO bricks.

The 962-piece set ($70 on Amazon) is based on a design from Jake Sadovich, a longtime LEGO fan from Idaho. Sadovich spent three weeks designing his own version of a ship in a bottle using 1400 LEGO bricks before uploading images of the finished result to the LEGO Ideas site in November 2016. His project received the 10,000 supporters it needed to garner a review from the LEGO team in less than two months, and in August 2017, the company green-lit plans to build and sell an official set based on his design.

Placed inside a bottle made of transparent bricks, the miniature ship boasts plenty of detailed features for its 5-inch-long size, including sails, six cannons, a crow’s nest, a compass (sorry, it isn’t a working one), and a flag. There's even a wax-sealed cork built out of LEGO bricks, too, as well as small LEGO pieces designed to serve as the water beneath the ship.

Some of the other fan-submitted LEGO Ideas projects the company has brought to life include the NASA Apollo Saturn V ($200) and a replica of the Central Perk set from Friends ($60).

Sling TV’s 14-Day Free Trial Gives You Access to Countless Movies and Shows, No Credit Card Required

You’ve probably encountered more than one so-called free trial that required you to input a credit card to access it. And if you’re like many of us, you have probably forgotten to cancel the trial before the free period ended—more than once. But Sling TV is looking to offer users a free trial that’s, well, actually free. From now until April 5, new subscribers can access over 50,000 on-demand movies, 45 channels, and more during their free 14-day trial, no credit card required.

Fittingly dubbed the “Quarantine Special,” the free trial gives viewers access to a Sling Blue subscription, which offers channels like CNN, MSNBC, Bravo, A&E, Cartoon Network, Nick Jr., and more. The Blue subscription also allows you to stream on up to three devices simultaneously and record live shows on their cloud DVR.

Rather than having to sign up for a long-term contract like with traditional cable, Sling is a month-to-month service that allows you to stream content to your TV or computer/smartphone through web browsers, Roku, Amazon, iOS, and Android devices.

After the free trial, you have the option of signing up for the Sling Blue or Orange subscription, both of which are $20 for the first month and then $30 after that. There are a few key differences between the two. According to Tom’s Guide, with Orange, you won’t have access to NBC networks. And with Blue, you won’t be able to watch ESPN or the Disney Channel. Orange only lets you stream on one device at a time, whereas with Blue, you can stream on up to three simultaneously. However, you can swap between the two for no extra cost, or you could combine the subscriptions for $45 a month.

Much like Sling, Disney Plus also allows subscribers to enjoy seven days (with a credit card) for no cost, and you can get more details by heading here. And if you're looking for more ways to save money as a cord-cutter, check out our guide on the cheapest ways to do so.
