Solar-powered Logitech keyboard appears on Amazon Mexico — MX Keys S look-alike promises up to 10 years of power

According to an early Amazon México listing, Logitech is preparing to launch the Signature Slim Solar+, a wireless keyboard in every sense of the word. The Signature Slim Solar+ features a solar panel, providing owners with a battery lasting up to 10 years.

Less sophisticated wireless keyboards utilize AA batteries that can last for several months. Conversely, some of the more advanced models depend on a cable or a wireless charging pad to replenish their batteries. The latest innovation from keyboard manufacturers involves the integration of solar panels. Similar implementations have been observed in products from Lenovo, and Logitech has done this before, too, with the K750 Wireless Solar.

The Signature Slim Solar+ design will look very familiar if you're a Logitech aficionado. The upcoming wireless graphite-colored keyboard resembles an MX Keys S, but it features an additional solar panel above the top row of keys. The narrow solar panel absorbs daylight or artificial light, so you don't have to worry about rainy days. The battery is said to have a lifespan of up to 10 years, according to Logitech. Your mileage will obviously vary, depending on your usage conditions.

Logitech has branded the wireless charging technology as "Logi LightCharge", described (translated from Spanish) as "a charging innovation that combines a light-absorbing strip and a long-lasting, energy-efficient battery." It could just be marketing talk, or Logitech added something extra, but we won't know for sure until the product has launched.

The Signature Slim Solar+, made from 70% recycled plastic, is a full-sized keyboard with a footprint of 15.9 x 5.6 x 8 inches (430.8 x 142.9 x 20.2 mm) and weighs 1.5 pounds (700 g). It's slightly larger than the MX Keys S due to the solar panel, but the Signature Slim Solar+ is up to 14% lighter.

Like other Logitech keyboards, you can pair the Signature Slim Solar+ with up to three devices and easily switch between them with a single key. The keys on the Signature Slim Solar+ are customizable through the Logi Options+ App software. Smart Actions support is available, enabling you to automate tasks and bind them to a single "Action Key" on your keyboard. The Signature Slim Solar+ also features an "AI Launch Key," Logitech's term for the Copilot key that activates the Microsoft AI assistant on Windows or Gemini in ChromeOS. It's useless outside of the aforementioned operating systems, but you can always reprogram the key to perform a different task.

The Signature Slim Solar+ employs Bluetooth technology to establish connections with your devices. Alternatively, if you wish to use it with a USB receiver, the keyboard is supplied with a Logi Bolt USB-C receiver.

The pricing and availability for the Signature Slim Solar+ are unknown, as Amazon México did not provide this information. However, since it's already listed, an official announcement from Logitech could be right around the corner.

I wouldn't have designed a keyboard to have the solar panel inside a concave depression above the function row.

A depression of that specific shape in that specific location on a keyboard has traditionally had the purpose of being a pencil tray ... which is for ... you know: storing a pencil, pen or a stylus.
There are hundreds of keyboard models with pencil trays, or just a ledge for preventing a pen laid above the keys from rubbing against the row of keys.

And of course, the use of it as a pencil tray would defeat the effectiveness of the solar panel.

No thank you. I will take a keyboard with no definite obsolescence date which utilizes replaceable batteries over a proprietary battery which has a known limited lifetime.

I was a fan of the K750 way back when they were new or so. For the solar but also because it was completely flat design which is what I like in my keyboards. But the battery is going to die eventually. I don't think it lasted 10 years like they claim for this one. But then that's it. I did pull the battery and tried replacing it with a similar type which they try to prevent you from doing but it still didn't work. So now it's useless. Unlike some cheaper Logitech wireless keyboards like the K270 which uses normal batteries and so you can easily replace them as needed. I have some of those around and they still work to this day even if they are cheap keyboards. If they could combine a solar recharge with a standard rechargeable and replaceable battery, then you'd have something. Or at least have a USB port as a backup so when the battery does eventually dies, you can still use it as a wired keyboard. But other then maybe using a better battery than the K750, this still seems just as crap.
