UGreen 300W GaN Charger review: Fast-charging with lots of high-power USB-C

in General Discussion edited September 16

The UGreen 300W GaN Charger is a heavy-duty USB-C desktop charger to ensure your entire setup is always charged.

Gallium Nitride (GaN) semiconductor technology seems to be becoming more popular, and new chargers and batteries are making the most of this change. Greater charging efficiency and power density over silicon semiconductors grant consumers more powerful chargers at smaller sizes.

The Ugreen 300W GaN charger is an example of this, as it splits its massive wattage to charge several high-power devices simultaneously. Ugreen has been making consumer electronics since 2012, specializing in chargers and power stations, and this is their most powerful charger yet.

This charger is not for day-to-day portability, weighing almost two pounds and coming with a separate power cord. Five different outlets make it great for office spaces, desks, or on a coffee table for charging devices in gathering spaces.

The matte grey color helps it not stand out too much, and rubber feet on the bottom help it hold in place on a table. The charger also comes with a 1.5m USB-C charging cable.

UGreen 300W GaN Charger - Ports & charging

With five ports and 300W, there are many ways for power to be split amongst your devices. Full details are available on Ugreen's website, but there's a simplified breakdown for the maximum power of each port.

  • USB-C 1: 140W

  • USB-C 2: 100W

  • USB-C 3: 60W

  • USB-C 4: 45W

  • USB-A 1: 22.5W

The wattage varies depending on the combination, but you could plug in three laptops or tablets into the top three ports and still get fast charging by using all 300W. We've used the Ugreen GaN charger over a few weeks and found that it was particularly good at getting devices back up to charge quickly, which has great applications for mobile workers and students.

When charging an iPhone 14, iPad, MacBook Pro, and AppleWatch simultaneously, the iPhone and MacBook went from 0% to 25% in around 10 minutes.

The iPhone reached 80% at around 50 minutes, and the iPad charged from 44% to 80% in 40 minutes. All devices were at 95% or above at 100 minutes.

All the while, the charger didn't warm up too much, which is proof of Ugreen's claim that the charger is always on temperature protection. We also noticed that when connected devices were at 100%, more power would be given to other ports to charge the remaining items.

A charger to last you years

The UGreen 300W GaN charger is a great way to bring fast charging to all your devices on your desktops, bedside tables, or offices. Wire mess is avoided, space is saved by using one charging block instead of five, and charging stays consistent and adapts to the situation.

Although the price is high, it's a good deal compared to buying several fast-charging blocks for the same effect. This charger is a long-term investment for those who want to avoid worrying about their devices running low on charge.

UGreen 300W GaN Charger Pros

  • Can charge several high-power devices simultaneously

  • Consolidates multiple charging blocks into one

  • Long-term investment for reliable charging

UGreen 300W GaN Charger Cons

  • Not for on-the-go use

  • High cost

Rating: 4 out of 5

    This company makes many products that are not UL certified. Nor do they contain any other lesser-known OSHA approved safety certifications. Is this one of those products? It’s hard to tell from the marketing photos, so I would hold off on these until more user review photos are posted. Unless things like that aren’t important to you, of course. 

    Caveat emptor.

    I'd want either a UL or Canadian Standards Association certification.  Probably some other certification agencies outside of North America...  

    Fast charging shortens the life of batteries, so it should only be used where REALLY needed (not for overnight charging).  I have a fast charger for use from a battery powered UPS (to charge cell phone during prolonged power outages of more than a day).  Probably should buy one to fit the cigarette lighter outlet in the car as well.  

    Should be able to hold off buying any new Apple products until 2027.  Good chance solid state batteries will be available before then.  Solid state batteries should be half the price, half the weight, half the size, and much less flammable.  VW plans to have them on their EV cars by 2026.
