330W 20V 16.5A Gaming Laptop Charger – Multi-Port Power Adapter Power Supply

I am thoroughly impressed with the product, significantly surpassing the default charger provided with my gaming laptop. Its compact size and weight make it more convenient to carry and use, while effectively keeping the laptop charged and ready. Although I encountered an issue after some time, the manufacturer’s communication was excellent, and my overall experience has been very positive. I am highly satisfied with both the product and the support provided. Well recommended if you want a slim and weightless power brick for your gaming experience!

I have been using this for ~9 months, since September 2024, and this thing is fantastic. I have a Lenovo Legion Pro 7i Gen 8 RTX 4080 laptop. It's a power hog, especially when running the graphics card at full, and has only limited functionality without a 330W brick attached. The OEM 330W that the laptop comes with is large and heavy. Not a problem when it's stationary and at a home dock, but a huge pain to move with anywhere, even just around the house, which is exactly why I ordered this SlimQ version. This thing is tiny compared to the OEM. It has been an absolute joy to be able to travel with it, use it around the house, bring it to coffee shops, etc. I have tested and verified it pulls ~330W when needed (actual number varies constantly according to laptop draw) and functions equivalently to the OEM brick for me. I am able to run games, ML training, videos, browsing, etc., with no power issues. I've noticed no differences in temperature under load from the OEM brick and have experienced no heat issues. The two 100W USB-C ports are icing on the cake and have actually made this the sole transformer I bring when traveling (aside from the laptop, everything else I travel with is USB-C). In the end, this gives me a full-power laptop charger and two 100W USB chargers, all with significantly reduced weight and volume. It's fantastic! It's such a simple thing, but honestly one of my favorite toys, so much so that I am excitedly purchasing the 150W variant for my wife's less power-hungry laptop. I've had a great experience and would highly recommend the SlimQ GaN chargers to all. I've noticed the manufacturer being quite active with support on Reddit and elsewhere. If you have questions or issues, give them a ping before or after purchasing and it seems likely that they'll be eager to help.

Awesome charger its super small charges everything I have super quickly, only complaint is the ports on the charger are super lose like the slightest pull and the cables fall out but besides that it's great. UPDATE After around 2 months my charger port has melted I've contacted support to and they offered me a new cable which is great but the cable wasn't the problem it was the whole thing and instead of just offering to replace it they're trying to make me jump through hoops of testing it on video as if I would want to plug it back into my laptop after it melted, when it worked it was just alright they also told me to fix the loose charger port to stick a pen into the prongs of the charger (with it unplugged of course) just seemed a bit silly it did work for like a day then just went to being lose

After ordering a replacement for my Gigabyte gaming laptop from overseas, I got impatient and decided to give this a whirl. I love the compact size of the charger and the carrying case that comes with it. It works great for my laptop and provides ample power for the mobile 4090 workhorse!

It works well and small for what it is but on the flip side, it's dense. It's also expensive (but expected for something this powerful). The two USB-C ports at 100w are nice. The dual usage to power both my Lenovo Thinkpad P15 Gen 2 and my 2024 MacBook Pro 14" is nice as not having to carry two chargers while traveling is worth the price.

I, like most people looking at this, was looking for a smaller power supply for my gaming laptop. The one that came with my MSI Raider GE68X is huge and frankly make the laptop less portable. The SlimQ one is indeed smaller and comes with a nice case. It also has additional USB-C ports for charging other electronics. With the case though, the entire package is comparable to just carrying the original brick, but the case means my bag is more organized, so I usually opt to bring it. Performance wise, I have not noticed any issues with the SlimQ. I ran several benchmarks and also have played several games without any discernible impact to GPU or CPU wattage.

Replaced the charger for my 2023 Asus G14 4090, 2025 Asus G16 5090, 2025 Asus G14 5080. It even works well with higher wattage VBIOS mods on these laptops (175w full fat 5090 vbios). 2025 g16 and g14 use the same adapter end (sold separately from SlimQ). It's considerably smaller, but slightly thicker than the stock 280w Asus charge bricks. The usb-c charging ports are a huge bonus.

After about four months of using, the smaller cord that extends from the brick to my laptop no longer stays plugged in. It slides out with the tiniest of movements. It started off tight, but has not become virtually unusable. not only that, but even wiggling the plug around causes my laptop to stop charging... It also still gets very hot. it seems like whatever internal component has separated from the plastic case around it. I have kept it in its nice carrying case whenever not using it, I've never spilled anything on it, its never been banged around etc... For how incredibly expensive this thing is, I wouldve expected it to last for at least a couple years, not just a few months...

Good travel charger for my Legion 7i 7 laptop i have taken the OEM charger but its very heavy when travelling this unit works well and has two USB outlets as well. I have been using this as the main charger at home to test out and no issues so far it works very well. You do however need to purchase the correct connectors separately as i did they work well as well but its an added cost.

It arrived as advertised , and it works great! I really love the high quality feel of the cables, makes me believe they will be durable when packed away. Also I didn’t realize it came with a nice case to transport, very nice touch. I reached out to the supplier before buying, they were very responsive. They actually recommended I do not get this product because based on specs it wouldn’t work with my ASUS rog strip scar 18. But I took the risk and got the converter and it works on performance mode. I don’t want to use it on turbo because I don’t want to put too much pressure on the system. That being said, if you are running a laptop that has a base 380+ watt charger, this system works with the adapter. Highly recommend, very pleased.

Looks great but does not infact work with ASUS laptop so pretty useless.

Works really great and the small bag it came it is perfect to carry and the texture of the cable is of amazing quality. Great for my laptop that needs 280 watts. really awesome quality and the cable holding that is attached to the cable is a really cool design , perfect to keep the cables attached

This is a very premium charger. It comes with a fancy case, and both cables connecting to it are made of a very nice, flexible material that I haven't seen anywhere else. Unfortunately, the GAN advantage of weight savings is very minimal in this product, so it's still quite heavy, though compact.
