Dreams of wireless power and charging have been around since the days of Nikola Tesla. But in the last few years, Qi charging has become common on phones and earbuds, smartwatches and even the occasional mouse. And now Lenovo is here to add wireless charging to your laptop, with the appropriately named Go Wireless Charging Kit.
As part of a new Lenovo Go line of accessories that also includes cork-adorned ergonomic keyboards and mice, the Go Wireless Kit is comprised of two main pieces. There's a moderately sized brushed nickel charging pad, and a wireless charging strip with two pogo pins on the bottom where the power gets transferred from the pad to your laptop. Lenovo says the charing happens with 93% efficiency, which hopefully means there will be very little heat generated in the process.
The charging strip plugs into an available USB-C charging port and sticks to the bottom of your laptop via an adhesive strip. While the charging strip is fairly thin (3.2mm), and could actually help your laptop keep cool by lifting the back end up a bit for better airflow, Lenovo also made it easily removable for those times when you'll be away from the charging pad and don't want the extra bulk. What actually gets stuck to the bottom of your laptop is a very slim plastic strip, which the charging section slides onto and off of fairly easily. So you don't need to keep it on your laptop all the time.
With the charging strip attached and plugged in to your USB-C port though, charging your laptop is as easy as placing it on the charging pad so that the two pogo pins on the strip make contact. The company says the kit should work with most 13-14-inch up to 65 watts with USB-C charging ports (Windows, Mac OS and Linux support is listed). Press materials for the kit say touchscreen laptops aren't supported. But a Lenovo press representative told us the primary reason for the absence of official support for touch laptops is that tapping and swiping on your laptop's display could move one of the pins off the pad and disrupt charging. So as long as you don't hulk out with your pointer finger while tapping and swiping, using this with a touch-enabled laptop will probably be fine.
Hopefully, if the Wireless Charging Kit catches on, Lenovo will eventually integrate the charging strip directly into future notebooks for a more streamlined look (also so you won't have to sacrifice a USB port). But for those who like the idea of wireless laptop charging who can't wait, Lenovo says the Go Wireless Charging Kit will start at $139.99 and should be available in October.

This article is highly misleading. Honestly, journalists need to do their due diligence these days and cut it out with the buzzwords. This has NOTHING to do with Tesla's concepts on induction. This is NOT wireless charging and absolutely NOT Qi for your laptop. It is not using induction but classic charging via metal pads. What the pad is actually doing is creating a circuit using a cheap trick. That's why there are metal prongs at the bottom. That's right: it is creating an electric circuit to charge your device. Repeat: It is NOT using air-transmitted electromagnetic induction. See here for yourself if you don't believe me:Reply
The story clearly says it uses pogo pins, multiple times, and shows them. I'm sorry if you feel the headline is misleading, but the point of a headline on some level is to boil down the main point/news in a way that a general audience can understand. And it is clearly like Qi in the sense that there's a pad that you put your laptop on and it charges, without having to plug a cable in.Reply
Perhaps a more accurate headline would have been "Lenovo's Go Wireless Kit Uses Pogo Pins to Charge Your Laptop," but 95% of readers (particularly those coming from Google and not from our homepage) would not know what that means and then not read the story. Clearly the technology is different, but the concept and use case is very similar between this and Qi. You place your device on a pad and it charges. That is why I noted the similarity in the headline. And note that I said it was "like" Qi, not that it "was" Qi.
Yes, i fully agreed with previous comments. This has nothing to with what telsa was trying to create. Its not inductive charging nor wireless power transfer (using radio waves or microwaves). Our phones are real wireless charging using EM induction. This is not.Reply
This is simply using pogo pins to make contact with a metallic pad and the internal circuitry determine which is + and -. Thats all.
The only thing "wireless" is that you do not have a wire going directly from the power adapter to your notebook.
