INVZI GaNHub 100W GaN USB-C Charger 4-Port 3C1A (GaNHub 100W)

Got to replace MacBook and Surface Studio Laptop chargers when travelling and still have sufficient ports to charge all family devices. Has been fast and reliable after two months of weekly use. At 7oz, it's heavier than the 65W unit it replaced. Like most travel adapters, the fold-out prongs can be a bit temperamental staying in with some power outlets due to weight.

Charges like a Banshee, super fast charging and has the USB A port for the oldies. Was only a little warm while pumping out 65W.
Powers & charges my Thinkpad X1 Yoga laptop.
I've had smaller GAN chargers this one is a little bigger with 3 USB C and an USB A port definitely worth the slightly larger size.

This charger is fast charging and has room for four connections at a time. It can fully charge my Samsung computer in about 1.5 hours from a completely dead battery

The size is amazing, and well suited as a universal travel charger, particularly for those of us who have gone all-USB-C. It feels heavy for its small size, but still lighter than any other laptop power bricks.

It should be noted, the 100W delivery is *only* at 20V; I didnt realize that this charger will only delivers 3A @ 15V (only delivering 45W, while the standard Surface Pro adapter is 60W). It doesnt seem to affect the charging and operation of the tablet though (using a USB-C cable through the proprietary Surface connector, not through the USB-C port on the tablet), and somehow seems to out-perform the MS 60W adapter when heavily loaded. Ive been able to run Zoom calls on the Surface, with an Amazon Fire tablet plugged in as a second monitor, phone plugged into the 20W outlet, and the charger manages to keep up with the load and charge the battery of all devices as well.

After a few hours of high-load use, it is slightly warm to the touch, but cooler than the standard Surface adapter (which routinely exceeds 105 degree surface temperature).

Only been using it a few weeks, but hope it lasts forever!

Have not used for long so can't judge longevity but as of now is full 100W charging and plenty of USB-C ports in a small package. Much smaller than 1-port Apple charger or even my first GaN charger.

My purpose in buying this was to find a USB charger that was small enough to fit into my existing travel case while giving me the power to charge high power devices simultaneously. This USB charger fulfills all of those rolls perfectly! The first thing that I noticed taking it out of the box was the weight. It is a little heavier than expected however this makes sense seeing as it is a 100 W charger. If you see some of the images that I attached you can see how the weight compares against the standard Apple laptop USB C charger and some of their smaller iPad and iPhone chargers. I've put it on my USB tester to verify the output of the various ports and everything seems to match up with what is listed on the charger. Obviously the maximum output fluctuates based on the device you're charging and how many devices you are trying to charge at the same time however, having this is better than having to worry about multiple chargers when you travel. I know one of the questions that everyone always has is because it is not from a brand-name company is it up to par with any other brands and so far I can say that it is. If that changes I will for sure come back and update this review.

Overall if you are looking for a portable USB charger that has all of the power you need to charge all of your devices on the go I can highly recommend this USB charger!

Pretty solid and appearance of the design sense, the size is also just suitable for outing use.

You must have one

Great Charger and its fast!

The best GaN charger I ever had by far. Highly recommended.
