During the MWC 2025 event, there were a bunch of cool tech products that were unveiled. But among the various announcements, we also got solar powered tech that boasted an alternative charging method for popular mobile devices like smartphones, laptops, and others. So here are unique tech products that you might have missed out on.

Infinix SolarEnergy-Reserving Technology

Smartphone maker Infinix just unveiled a new method for power management for smartphones. The company debuted the SolarEnergy-Reserving Technology uses perovskite photovoltaic technology along with AI algorithms. This concept allows smartphones to capture and store light energy from indoor and outdoor sources. In other words, the tech can revolutionize mobile energy by using solar power integration.

Infinix employs this tech by pairing a device with a special phone case that seamlessly transfers energy through discreet contact points, ensuring continuous power availability. Thanks to Sunflower Wireless Charging technology, the brand also adjusts power transmission over a range of 3 meters. Furthermore, this system also has emergency power access for power access even during outages. The brand believes that future devices may support sustainable charging tech.

Lenovo Yoga Solar PC Concept

Lenovo’s MWC booth had some unique new products that employed solar energy. The best example of this is the Yoga Solar PC Proof of Concept. This prototype laptop model has the top lid covered with a large solar panel that can directly absorb sunlight. As per official claims, the Yoga Solar PC Concept can offer up to one hour of video playback from being under direct sunlight for just 20 minutes.

Solar powered gadgets aren’t new but these show a practical way of using them on popular mobile computing devices. Additionally, the notebook uses a Dynamic Solar Tracking system that can optimize energy absorption by adjusting the panel’s setting based on the sunlight’s intensity.

Lenovo Solar Power Kit

Another tech product from Lenovo that uses solar energy is the Lenovo Solar Power Kit. As the name suggests, it is a power kit that was designed specifically for outdoor use. This aims to offer portable and reliable power to keep devices charged even when you’re at work or out on an adventure.

Solar Powered Lenovo Keyboard

Lastly, we have a brand new Lenovo keyboard. The popular PC maker showcased a new keyboard that features a solar panel on the top. Similar to the other products that Lenovo debuted at MWC 2025, this gadget also powers through sunlight. This makes it perfect for outdoor use as well.

The post Every Cool Solar Powered Tech Showcased at MWC 2025: Solar Charging Laptops, Smartphones, & More appeared first on Gizmochina.

At MWC 2025, Lenovo showcased an innovative and eco-friendly concept: the Yoga Solar PC Proof of Concept. This groundbreaking laptop features an integrated solar panel, which allows users to charge their devices outdoors without having to rely completely on traditional chargers.

But how much power can it harness? Well, the solar panel can actually add some juice to your battery. According to the company, the solar panel absorbs enough direct sunlight in 20 minutes to power up to one hour of video playback.

This particular setup runs on Intel’s “Lunar Lake” Core Ultra 200 platform. So a future consumer PC with a Snapdragon SoC could potentially run even longer with a similar solar cell.

Alongside the laptop, Lenovo also introduced a Yoga Solar PC kit, a portable solar charging solution compatible with any USB-C device. The panel is remarkably thin at 15 mm, and the entire laptop weighs just 1.5 kg, making it portable and practical for outdoor use.

How it works

The Yoga Solar PC Proof of Concept features a solar panel that can charge the laptop both during use and when idle. The solar panel leverages Back Contact Cell technology, which moves mounting brackets and grid lines to the back of the solar cells, increasing efficiency to 24%—higher than the 19-20% efficiency of most commercially available solar cells. Additionally, the Dynamic Solar Tracking system optimizes energy absorption by adjusting the panel’s settings based on sunlight intensity.

While people generally do not work outdoors in direct sunlight or leave their PC in that situation, this proof of concept will at least allow you to stay connected when the power grid is not active or when you’re outside.

The prototype in the venue was in black, but the company seems to be experimenting with different colors too before commerical release.

Lenovo has not yet announced pricing or availability for the Yoga Solar PC Proof of Concept.
