Startup Made in Mind claims to have a slim charging solution for all devices, including laptops-- the Mu One, a USB-C charger able to support USB Power Delivery with maximum voltage reaching 20V.

The Mu one can be used with all devices, including USB-C laptops such as the latest Apple MacBooks. It is the brainchild of Min-Kyu Choi, the creator of a foldable USB-enabled UK plug, and comes with interchangeable plugs, a fully-foldable UK plug, a hinged European plug and a low-profile US plug. The result is a charger just 14mm thick when folded and weighing 80g.

Hong Kong-based startup Greenbulb takes to Kickstarter to launch a lower-cost alternative to the Apple Pencil-- the SonarPen, an iPad stylus users connect to the tablet via 3.5mm headphone jack.

Compatible with any iPad released after 2011, the SonarPen uses an interesting means to transmit pressure data to the iPad. It essentially turns pressure information into sound waves, which in turn are carried by the audio cable. The iPad then interprets the audio signals back into digital information.

Dell publishes a video showing off the DA300-- a puck-shaped 6-in-1 USB-C adapter offering video, data and LAN connections complete with a self-contained retractable USB-C cable.

Described by the company as an ideal accessory for connecting multiple devices, including displays, printers and ethernet, the DA300 offers HDMI, VGA, DisplayPort, USB-A, USB-C and RJ45 ports. In turn it connects with PCs or laptops via retractable USB-C cable, and users can extend the cable by simply rotating the puck.

Last year Corsair released the K68, a mechanical keyboard with an IP32 rating making it spill- and dust-proof. Now the PC accessory maker releases a version adding coloured LED lighting, the K68 RGB.

Like the previous model, each keycap on the K68 RGB has an individual silicone rubber shield to protect the internal hardware from any accident involving spilled drinks or snacks. Inside the keys is a choice of either Cherry MX Red or Blue switches and, new to this model, coloured LEDs for rainbow lighting effects.
