Charge your smartphone halfway in 4 minutes Infinix 180W Thunder

The growing company Infinix decided to compete with the giants of the market for ultra-fast charges and introduced the 180W Thunder Charge.

Charge your smartphone halfway in 4 minutes.  Infinix 180W Thunder Charge ultra-fast charging introduced

As the name suggests, this is 180W fast charging technology. Unlike Ultra Fast Charge 160W technology, which was just a concept, 180-watt charging will appear in the company’s smartphones, and already at the end of this year. It will debut in a flagship smartphone, but there are no details about it yet.

Infinix says this technology will allow a 4,500 mAh battery to be charged up to 50% in 4 minutes. How much will be needed for a full charge, the company does not say, but you should not multiply the indicated time by two.

Since we are talking about huge power for a mobile device, 180W Thunder Charge technology has received 111 software and hardware security mechanisms that monitor many different indicators, including temperature, voltage, electromagnetic interference, and so on.

It also implies the presence of 20 temperature sensors that will monitor the temperature of the battery, USB-C port, converters, and so on. The system will focus on keeping the temperature below 43 degrees.

Also Infinix will use special cables with identification chips. Only with such a cable will ultra-fast charging be activated. In the case of other cables, charging will still be fast: 60 or 100 watts.

The future is here a prototype of augmented reality contact

The company Mojo Vision recently spoke about its new development – contact lenses with augmented reality. They were tested by the head of the company, Drew Perkins. With the help of lenses, he was able to navigate in space, looked at images and even read text from a virtual teleprompter.

The current prototype is equipped with a MicroLED screen with a resolution of 250 by 250 pixels, its diameter is only 0.5 mm. The lenses receive a signal at a frequency of 5 GHz and work on the basis of a very small processor with Arm architecture. This allows them to overlay digital objects on top of the real world image.
