Anyone invested in the Apple ecosystem will have had to confront the need for multiple USB-C ports when they're home and away, with iPhones, iPads, and Macs all vying for the connectivity these days. But in many cases, there's still a lingering need for USB-A to charge older devices, and that's where Ugreen's 4-in-1 100W GaN X Fast Charger comes in handy.

The charger packs three USB-C ports along with a single USB-A port, but despite that throwback it offers the latest Gallium Nitride technology, which is popular with modern power adapters because it allows for better power efficiency that results in smaller product designs more suited for travel.

I had the opportunity to test Ugreen's multi-port charger in both its UK and US variants, and the first thing to note is that the US version is the more portable design. It's a slender square brick that fits in the palm of your hand – it's a little smaller than Apple's 67W UK charger that comes with the 14-inch MacBook Pro, and benefits from the two-pin A plug's ability to fold away inside the body.

By contrast, the UK model has more of a bulky cuboid shape with rounded corners, and the three-pin D plug isn't foldaway or retractable, making it harder to slip it neatly into a travel bag without snagging on something.

Other than that, both models are functionally identical and feature a built-in "Power-X" power delivery system that can intelligently adjust the power output to protect a device's battery. Essentially, the power distribution system allows the charger to adjust the power provided to each port based on what's plugged in. The top two ports are capable of delivering a maximum of 100W, while the third is capable of up to 22.5W, and the bottom USB-A port offers 22.5W.

Ugreen claims that this means it can charge an iPhone 13 to 60% in 30 minutes or fully charge a 16-inch MacBook Pro in 1.5 hours, and thanks to the latest GaN chipset, it's three times faster than Apple's standard iPhone charger. Those claims stood up to scrutiny in my tests, although the big caveat here of course is that they only apply when one device is plugged into the charger and in the relevant port for its power requirements.

Ugreen includes a graphic (shown above) that explains the variable wattage of the different ports based on what's plugged in. For example, if you have two devices connected to the first two (100W) ports, the top port outputs 65W and the second port delivers just 30W. As you'd expect, the charger's power output gets divvied up further the more devices you connect. For instance, when all four ports are occupied, the first (100W) port tops out at 45W, so you have to consider what you're plugging in if you want to prioritize a particular device for fast charging at maximum wattage.

Unfortunately neither the US nor the UK model has the max wattage marked on the individual ports, so I wasn't always sure which port was the right one to use to get, say, the full 100W to power my MacBook Pro, but it didn't take too long for me to memorize them so I didn't have to keep referring back to the included manual. Remembering all the variable combinations however is a little more tricky – it's better off simply accepting that the more devices you're charging, the longer they'll all take to reach full battery capacity.

The chargers also feature an "Over Temperature Protection" system that takes five temperature readings every second for extra security, which is the kind of feature that's not obvious but is nevertheless good to know exists.

Final thoughts

Ugreen could have designed this 4-in-1 charger to be larger unit with a fixed power output to several USB-C devices, but instead it has opted for a more compact brick with variable power distribution. This shouldn't be a problem if you intend to use it to charge a number of devices overnight, but if you're looking to fast charge a single power-hungry device like a MacBook Pro then you're better off treating this as a solo charger or opting for a more bulky alternative.

The addition of a USB-A port is a welcome nod to the number of older devices still in circulation, and adds to the charger's flexibility, even if that does mean sacrificing a fourth USB-C port. All in all, this makes the Ugreen 100W Charger an accommodating, travel-friendly unit (especially the US variant) that's certainly worth having on hand when you're away.

Bought one of these a while back and had issues with it. The charging disconnects when one rechargeable device is 100% for all devices and always struggled to get it working with MagSafe and watch charging. It also started to cause issues with my ipad screen with the display of apps being larger than the screen so it cut off the edges. Not sure how it caused this but didn’t happen when connected to other chargers. In the end I returned it. Waiting to get my hands on a Satechi one instead.
 
I'd love to know why it can't do 45 / 45 for the first two ports.

Also does this suffer from the common GaN issue where the charger lowers the output to the 1st port if a cable is plugged into a 2nd/3rd/4th port (with no device connected to the other end)?

I am a fan of the RavPower RP-PC136. Also a small design, 2x USB-C + 2x USB-A, 65w PD and most importantly (for me) it has a figure of 8 power inlet (like most apple units) so I can just change the cable when travelling for one that matches the local power outlets.
 
Great feedback from users on this forum, sounds like it is not 100% reliable.

Looking for something like this for travels/trips where one charger would charge me everything overnight

Nintendo Switch / MacBook / iPhone / AirPods / Kindle or something.

I usually charge my Watch during shower as I use it In the evening for sleep track
 
from the experience, Baseus does better job at Gan Charger than ugreen.

Ugreen seems to be malfunction after few months of usage somehow, in my case
I have the Baseus version of this exact charger (3xC 1xA). I think the Baseus power values are a little better distributed, but basically the same. It's been perfect so far and picked it up for less than 40 bucks during Cyber Monday last year.

I disagree. The design is inherently travel-unfriendly, if you happen to travel internationally.

When I travel, I tend to have three problems with chargers:
  1. I need at least three different plugs (US, UK, EU, sometimes others). This needs an awkward and flimsy dongle.
  2. There will be situations where wall warts just do not fit into sockets (due to neighbouring devices, furniture, etc.)
  3. The sockets are often close to the floor (under a bed, behind a sofa, etc.), and plugging in the devices to be powered is difficult and requires long charging cables.
All three problems can be solved very conveniently by having a charger with a separate power chord with standard connector ("figure eight"). If I travel in the US, I take the US power chord with me. If I travel in the UK, I have a UK power chord. And if I forget my power chord, I'll use the one in the hotel room's TV set or buy a new one locally.
 
I'd buy one. the specs look good. but kinda a lot of money at $80.
You can get it for under 50 at AliExpress at their official store.

I've been using this charger daily for the last 4 months now with no issues at all. Use it for my work PC, while charging my iPhone and other accessories.
Question. Do chargers with high W output do any harm on devices battery with a low W input?
No, the device only draw the amount of wattage it needs.

I disagree with you again, but my travels are probably different than yours. :) I only travel within EU power socket outlets and I want something that is as small as possible to fit in my small carry-on. For that use having a cable from the socket to the charger is cumbersome. Yes, I do need one long USB-C for my PC, but that type of cable is smaller and more easy to handle than a regular power cable. When what you want is the smallest possible 100W, this is the way to go.
 
I have recently picked up the Ugreen from Amazon. It is a touch different in that it doesn't have the test print by the ports. I am talking about the photo here that shows two and the one on the left is about the same in shape/size. I gather Ugreen did some deal with Amazon and it ran 69.xx at the time (weeks ago).

I have not tested it with anything beyond an iPad Pro and also iPhone. It seems to work fine but as others mention, when items are fully charged or disconnected, often Gan chargers will try to adjust their wattage per device which may cause a disconnect and perhaps not return with renegotiated wattage. I have only used one at a time.

For the iPhone, I have used both the USB C and USB A with the following setup
USB C higher wattage with 5a cable (lightning)
USB C lower wattage with Apple's cable
USB A lower wattage with Apple's cable

They all do charge well but I do believe the higher wattage USB C actually is a touch faster. I know that some say that the iPhones of today work fastest with the Apple 20 watt charger but I was getting at least 20 watts with the higher watt USB C port.

My items to charge - iPhone 13 Pro. Max, iPad Pro 12.x 2020, (2x) airpods2, and a 200 watt battery pack.
 
I have the 65w version of this with the same ports. I use it to charge an iPad Air, iPhone 12 mini, and Apple Watch. This shouldn't be too much power draw, yet for some reason one of the devices connected will just not charge. It will start charging, then at some point stop. This is very frustrating when I leave my devices to charge overnight and in the morning one of them is not.
I like the amount of ports, and the USB-A for legacy devices, but the unreliability has been frustrating and I wouldn't buy from them again.
 
I’ve looked at a lot of multiport chargers, and anything that does more than 20W across more than 2 ports just gets too complicated to figure out which port does what. Charging phones, iPads and accessories may be fine for 4 port chargers, but I’ve given up on anything that would also charge a USB-C laptop at the same time. Better to just have one high wattage charger and leave the multiport chargers for accessories
 
Is there anyone who uses Belkin 4-Port GaN Charger 108W?
Looks great, listed on Apple's official homepage. I'd like to have your opinions before I buy it.

No. Usually the charger and device talk about how much power to use, and IIRC if that's not possible the charger defaults to something low like 5W. I've charged iPads with 96W MacBook Pro chargers and nothing bad happened.

I have the UK version and I love it, but the non-foldable prongs are definitely a design choice. Let's remember that the Apple Charger has foldable prongs:

I like to think that Jony designed that charger himself as a love letter to us Brits. It's a wonderful design.
