Keep your laptop battery topped off without plugging it in.
We’ve said it before, and we’ll say it again – Lenovo’s Yoga Solar PC Concept is one of the coolest devices we’ve seen at Mobile World Congress 2025. If the name didn’t give it away, this is a laptop that can charge up its internal battery with nothing but sunlight. Lenovo incorporated a solar panel into the lid of the laptop so it can passively charge while you use it. Solar charging isn’t incredibly fast, but that isn’t the point.
The point is this is a laptop that you wouldn’t always need to have a charger for. You wouldn’t even need a power bank. All you need is a sunny day and for the light to hit that solar panel. Imagine taking your laptop with you to your favorite coffee shop. Oops! You forgot the charger, and the battery is lower than you thought. With this laptop you wouldn’t have to worry. You could just sit by the window and let the sun beat down on it.
That is a very cool feature, which is why we gave the Yoga Solar PC Concept an award during Mobile World Congress this week.
This laptop has a 24% solar conversion rate
This might not sound impressive if you aren’t really familiar with solar conversion rates. We weren’t, but after reading about what Lenovo did here, we’re convinced this is something special. According to the company, the Solar PC Concept and its 24% solar conversion rate is one of the highest in the industry. That’s impressive. It’s also exciting to think about how quickly the laptop would be able to charge up.
Now, this is just a concept device, so it might not ever be something you can buy. Having said that, the use case of something like this is completely practical. We could see it become something Lenovo pushes into production and eventually sells. It seems like a laptop that people would actually buy.
20 minutes of charging gives you about an hour of video playback
I can’t even begin to count on my ten fingers how many times I’ve been in a situation where I had low battery life on my laptop and forgot the charger. All the while, I just wanted to enjoy some free time watching videos on YouTube or somewhere else. If only I had something like this to allow the laptop to charge up with sunlight. In just 20 minutes, according to Lenovo, the laptop would provide an hour of video playback.
Think about how cool that would be. You’d never have to worry about forgetting your laptop charger again. Well, as long as there’s sunlight to keep the laptop juiced up. What’s also impressive is that Lenovo says this laptop weighs around 2.29 lbs., so it’s not heavy. That’s some extreme utility. A laptop that charges via sunlight and doesn’t weigh down your backpack.
