Xbox controller charging station

Fosmon Xbox controller charging station
Now that gaming has gone wireless, I've been playing a lot less. My controllers are always dead, not because the batteries don't last, but because I can't be bothered to charge the batteries. Don't be like me. Today, you can get this Fosmon Xbox One, One X, and One S charging station and two 1,000mAh rechargeable batteries for 56 percent off. Instead of having to replace AAs, you insert the rechargeable battery pack into the controller and place the entire controller on the Fosmon charging rack. When it's charged—it takes about 4-5 hours—two lights on the charger turn green. Get one today for less than $18.Amazon

Electric blade-sharpening tool

Professional-grade electric sharpening tool
Today you can grab this Chefs Choice 15 Trizor XV professional-grade electric sharpening tool for 33 percent off. The device sharpens in three steps: the first two use diamond to sharpen and the last uses a flexible abrasive system to polish. It takes less than a minute to sharpen a 15-degree (a measurement of sharpness) knife, and can even turn a 20-degree blade into a sharper 15-degree blade. The device weighs only 4.4 pounds, so it's easy to store. Right now, you can get one for $100.Amazon

Anker's car charger

Anker PowerDrive Speed+ Duo car charger
Use the code ANKERPC2 at checkout to save $7 on Anker's PowerDrive Speed+ Duo car charger. After being on the road for the past two weeks, using my phone for GPS and Spotify streaming for hours at a time, I quickly realized how important a steady power source is. We tried picking up a car charger from a rest stop, but it was bulky, slow, noisy and only had one USB port. This Anker car charging port is not only smaller and quieter, but also features two USB ports—one USB (for most devices) and one USB-C (for your new phone or laptop). $18.Amazon

Roborock E20 robot vacuum

Roborock E20 robot vacuum
Sometime a floor doesn't get clean with just a vacuum. This 7-pound Roborock E20 also mops. The device has a detachable small water tank on the front as well as a repository for sucked-up debris. It intelligently learns your floor plan—up to 1,600 square feet—boosts its suction when it roves onto carpets, and can be controlled via Amazon Alexa. When the battery is running low, it automatically returns to its charging station. The dustbin is large and the smartphone app lets you control most of its functions. Today, you can get the $330 vacuum for $260.Amazon
