If the reply is sure, then you definately’ll have an interest to listen to that on a current household vacation, I introduced alongside only a single multisocket quick charger — the Ugreen 100W GaN charger — to cost all of our gadgets whereas on the journey.

I’ll clarify on this overview why a easy Amazon for $62 solves all of the woes associated to charging, particularly if you end up touring.

In at this time’s technology-dependent world, we’re consistently juggling good gadgets. Holding all of them juiced up with enough battery is as very important as staying updated on social media. However whereas we love to reinforce each side of our lives with these gadgets, charging them stays to be essentially the most painful facet of proudly owning and counting on them. Some smartphone and laptop computer manufacturers similar to OnePlus and Xiaomi have tried to deal with this ordeal by launching superfast proprietary charging applied sciences. In distinction, others like Apple and Samsung make the most of non-proprietary requirements like USB-PD (Energy Supply) and PPS (Programmable Energy Provide) to dispense quicker charging on their gadgets.

In addition to the problem of how shortly we are able to cost our gadgets, we face the constraints of what number of can we cost directly. The Ugreen 100W GaN charger addresses each of those constraints by permitting 4 gadgets to be fast-charged concurrently. However earlier than delving into the specifics of this succesful gadget, allow us to discover what a GaN charger is and the way it impacts charging.

What’s a GaN charger?

Silicon is a semiconductor that’s broadly utilized in circuitry for digital elements. Silicon has been used as a semiconductor for over 60 years, and scientists consider they might quickly be approaching the theoretical restrict of silicon-based chips.

GaN, or gallium nitride, is a extra environment friendly semiconductor used as a substitute for silicon. The vitality hole between the valence and the conducting bands on GaN is almost triple in comparison with silicon, and this offers it a lot electrical and thermal stability at excessive voltage and temperatures.

Subsequently, for functions with greater voltages and lengthy length, whereas silicon tends to offset a number of warmth — resulting in wasted vitality, GaN is a perfect substitute. GaN can also be a greater conductor of electrical energy than silicon at excessive voltage, which implies electrical present passes quicker by it. These properties make GaN extra fascinating for chargers.

GaN-based semiconductors require a lot smaller house to ship the identical energy as silicon. This is the reason a normal silicon chip might be changed with a GaN chip that’s a lot smaller in measurement. In consequence, GaN chargers are comparatively smaller than normal chargers whereas being extra environment friendly and delivering extra energy.

Typical GaN chargers can ship an influence output upwards of 100W, whereas some firms similar to Oppo and Xiaomi have even achieved speeds greater than 200W. At MWC 2022, Oppo demonstrated its 240W GaN charger that may cost a 4,500mAh battery to 100% in underneath 10 minutes.

However regardless of all its advantages, GaN has one main tradeoff: The manufacturing value tied to the advanced course of required to rectify its crystal defects. Subsequently, the functions of GaN are restricted to equipment similar to chargers and haven’t been utilized to the manufacturing of smartphones and PCs.

Construct high quality

Now that we now have a good understanding of a GaN charger’s benefits, allow us to give attention to the 100W GaN charger from Ugreen. The Ugreen charger has a stable development. Though the outer shell is fabricated from plastic, it feels exceptionally sturdy.

The Ugreen 100W GaN charger I acquired has a flat 3-pin plug generally used within the UK. However the firm additionally sells the identical 100W charger with plugs used within the U.S. and Europe. In comparison with the fashions designed for the U.S. and Europe, the U.Okay. model has rounder edges, however is thicker and marginally heavier. The U.S. variant weighs roughly 235 grams, whereas the U.Okay. variant weighs 245 grams. The burden feels corresponding to the Apple 61W charger for my MacBook Professional 2020, and contemplating it replaces 4 charging bricks, it ought to solely be a bonus if you end up lugging it round in a backpack.

The Ugreen 100W GaN charger seems to be premium and feels stable.

Given its use of GaN, the Ugreen charger within reason compact and suits simply within the palm. Its heft does make it vulnerable to slipping out of the ability outlet, particularly if you’re utilizing all 4 ports. That is far much less problematic for the U.Okay. variant because the earthing pin does present extra stability within the socket.

The exterior shell is available in a darkish grey colour and feels just like a brushed aluminum floor by way of really feel. This provides the charger a premium look, and it might even achieve fooling you that it’s fabricated from steel and never plastic. General, the charger feels strong, and whereas I’d not suggest doing so consciously, it ought to be capable of stand up to some reasonable falls.

Supported charging requirements

The highest two out of the three USB Sort-C ports on the charger help charging at 100W — when used individually — whereas the third one is proscribed to charging at solely 22.5W. The underside-most port, i.e., the USB Sort-A port, can also be restricted to 22.5W. Though Ugreen endorses a 100W output from the charger, you have to keep in mind this solely applies in the event you use the charger to cost only one gadget at a time.

Charging speeds on every port

The 100W energy is split among the many ports while you join two gadgets. The ability output of the topmost port is decreased to 65W, whereas the second port is proscribed to 30W. The ability output of the remaining two ports stays unchanged. In the meantime, while you interact all three USB Sort-C ports, the utmost output of the topmost port is additional restricted to solely 45W. Lastly, when all 4 ports are getting used, the ability output of all of the ports from high to backside is 45W, 30W, 10.5W, and 10.5W, respectively.

Thus, even while you interact all 4 ports, you’ll be able to fast-charge at the very least two gadgets utilizing this charger. As well as, the 45W output is enough to drive a laptop computer that helps charging by way of USB — though to not cost it in a short time.

Charging protocols supported by every port

The Ugreen charger helps USB-PD 3.0 and Qualcomm’s Fast Cost 4+ by all three USB Sort-C ports. Alongside USB-PD, the charger additionally helps PPS — a more recent normal that enables the charger to control output present and voltage in micro-step, thereby leading to extra environment friendly use of vitality and decreased waste within the type of warmth. Help for PPS additionally signifies that the Ugreen charger can pump cost into flagship Samsung telephones, together with the Galaxy S22 Extremely, utilizing any of the three USB Sort-C ports.

The USB Sort-A port on the backside helps Qualcomm’s Fast Cost 3, amongst different extra widespread charging requirements.

The huge gamut of supported charging requirements means in addition to your laptops, smartphones, and tablets, you may also cost your smartwatches, headphones, earbuds, wi-fi keyboards and mice, or handheld gaming consoles such because the Nintendo Swap.

Charging instances for various merchandise

Whereas Ugreen’s case seems compelling on the specs desk, real-life efficiency is what issues. To check the precise caliber of the charger, I attempted 5 totally different gadgets with it and famous the cost taken by every gadget in half-hour to ascertain a stage enjoying area. These gadgets had been left untouched through the charging interval to forestall various workloads from affecting the outcomes.

Listed below are my observations on the charging efficiency of the Ugreen:

  • My 13-inch MacBook Professional 2020 went from 1% to 48% in half-hour utilizing the Ugreen charger. That is barely greater than what I obtained utilizing the usual 61W charger equipped with the MacBook. Notably, the 13-inch MacBook Professional can solely obtain a cost at a most price of 61W (yow will discover out your MacBook’s most supported energy enter on the underside case close to the show hinge). Subsequently, the Ugreen charger’s full functionality couldn’t be utilized.
  • The Galaxy S22 Extremely went from 18% to 60% in half-hour and took almost 70 minutes to finish charging. Regardless that the Galaxy S22 Extremely helps quick charging at 45W, the charging pace doesn’t seem dazzling, particularly after we have a look at manufacturers similar to OnePlus and Xiaomi that already promote telephones with a lot quicker charging.
    However Samsung is the possible perpetrator right here, as Andy Boxall, senior cellular author at Digital Tendencies, famous in his overview of the Galaxy S22 Extremely. As seen throughout his overview, the distinction between a 25W Samsung charger and one rated for 45W is just marginal. In my testing, charging with the Ugreen charger shows “tremendous quick charging” on the cellphone, whereas utilizing every other charger exhibits solely “quick charging.”
  • To check how a lot quicker I can cost a smartphone, I used the Xiaomi 11i HyperCharge — a cellphone that takes solely 20 minutes to cost absolutely and comes with a 120W charger in its field. Whereas it makes use of Xiaomi’s proprietary charging expertise to refill the battery in lower than 20 minutes, it additionally helps non-proprietary chargers with USB-PD at a most charging price of 68W.
    Throughout my testing, the Xiaomi 11i HyperCharge went from 10% to 100% in simply 24 minutes when hooked to the GaN charger. This result’s nothing however spectacular.
  • Along with these fast-charging gadgets, I additionally examined a few slow-charging gadgets. First, the iPhone 11 went from 57% to 84% in half-hour of charging with the Ugreen GaN charger. For the reason that iPhone 11 can solely cost at as much as 22W, all three USB Sort-C ports would ship the identical efficiency. Not a lot has modified by way of the iPhone’s charging speeds, and the newer iPhone 13 can also be caught on the identical charging pace.
  • Fnally, the Galaxy Z Flip 3 was the slowest of the lot. Whereas it’s formally restricted to 25W charging, it went from 42% to 66% in half-hour, indicating a lot slower charging. The foldable additionally obtained significantly scorching, which can have led to slower charging.

This swift and versatile is the proper charger on your MacBook, Dell XPS, or Galaxy S22 Extremely.

My findings for the charging assessments are summed up within the desk beneath:

System Max supported charging price Change in battery % after half-hour
Apple MacBook Professional 2020 (13-inch, Intel) 61W 47%
Samsung Galaxy S22 Extremely 45W (PPS),
25W (USB-PD)
Xiaomi 11i HyperCharge 120W(proprietary tech),
68W (USB-PD)
Charging accomplished in 24 minutes
iPhone 11 22W 27%
Samsung Galaxy Z Flip 3 25W 24%

Are there any downsides?

I’ve a number of minor gripes with the Ugreen GaN charger. First, as I discussed above, its weight makes it vulnerable to falling out of the ability socket, particularly when utilizing the U.S. plug variant.

Secondly, while you plug in a brand new gadget, the already plugged-in gadgets will cease charging for a second. That is most likely as a result of the charging speeds readjust when a number of ports are engaged. I reckon this would possibly sound like nitpicking and will not trouble nearly all of the customers, but when it weren’t for this, I’d most likely give this charger an ideal rating of 5 stars.

Lastly, you can not quick cost telephones from manufacturers like OnePlus or Oppo that provide superfast however proprietary charging.


The Ugreen 100W GaN charger is offered on Amazon for $62 (together with a $6 coupon). You may also purchase the U.Okay. plug for 60 British kilos on Amazon UK (together with a 20-pound coupon). Lastly, if you’re on the lookout for EU-type plug, yow will discover it on Amazon Germany for 75 euros (together with a 5-euro coupon).

Folks in Asia can even purchase it on AliExpress.

Our take

The Ugreen 100W GaN charger is a compact and charming gadget that may simply substitute 4 of your charging bricks. In addition to being a improbable workplace or bedside gadget, the Ugreen GaN charger is the definitive resolution for journey and can ease your burden of carrying totally different chargers for various gadgets. In addition to being the proper charging resolution that will help you preserve your work desk organized, the Ugreen 100W GaN charger can also be splendid in the event you personal a cellphone or laptop computer that helps non-proprietary quick charging requirements similar to USB-PD PPS. This is the reason it is usually a wonderful charger on your new and glossy Samsung Galaxy S22 Extremely that doesn’t include a charger inside the field.

Is there a greater different?

In case you are on the lookout for barely extra energy output whereas additionally having the ability to cost 4 gadgets directly, you’ll be able to take into account the Spigen 120W GaN charger on Amazon for $100. Nevertheless, you’ll solely get two USB Sort-C ports alongside two USB Sort-A ports and also will need to shell almost $35 extra for the additional energy.

There are a number of different manufacturers promoting superfast GaN chargers rated at 100W or greater on Amazon, and people are comparatively extra inexpensive than the Ugreen charger. However we can not suggest them with out testing them ourselves.

How lengthy with it final?

Ugreen tells me that the 100W GaN charger might be plugged in 10,000 instances and even contends that that is greater than the trade normal. That many charging cycles means you’ll be able to simply use it for a decade, and by then, there can be a greater expertise that may substitute it.
