The most recent semiconductor revolution introduced us GaN know-how, which began out timidly, providing 10-20W in a barely extra compact casing than conventional chargers, however shortly gained momentum and the producer turned a lot bolder.
That is how we ended up with transportable chargers able to outputting 140W (and extra) from a single USB port, whereas protecting warmth loss to a minimal, so it isn’t tough to drive a number of laptops on the identical time. I have to put extra emphasis on the transportable facet as a result of a few of these chargers may be carried in a pocket (a much bigger one, however the level nonetheless stands).
I attempted the UGreen 100W just a few months in the past and plainly the producer determined to launch a 140W GaN charger as nicely, which might put it in direct competitors with Apple’s 140W charger, in addition to the opposite producers, similar to Kovol (with their Dash charger). of 140W).
Apple tried to shut the hole on third-party producers when it mainly left the charger out of the field for its iPhones, however its 140W GaN charger solely has one out there USB port, whereas the 140W UGreen Nexode charger has three out there. . , together with a USB-A port.
And there’s one other accent that UGreen has added within the package deal that has pleasantly stunned me and that may be a USB-C cable! Lastly somebody added a wire and it is twisted; it additionally measures roughly 5 ft (1.5 meters), which is lengthy sufficient for many functions.
The UGreen Nexode 140W charger is extra compact than the Kovol Dash 140W (which was surprisingly small by itself), measuring 3.0 x 3.0 x 1.4 inches (7.6 x 7.6 x 3.5 cm). . It is not the smallest charger on the market, however for 140W output, it is very compact, plus the retractable plug ensures it will simply slip right into a bag (and even pocket).
Non-US variations haven’t got this luxurious, as a result of the plug will probably be fastened and mentioning (clearly). The case is fabricated from plastic with three fused elements that create a pleasant visible impact, however the charger feels a bit unusual within the hand. Similar to plastic it may bend, even when it does not. Just like the 100W charger, the UGreen Nexode 140W doesn’t have an influence LED to let you already know the gadget is linked to an influence supply.
But it surely has three USB ports. The highest one is a USB-A port that may go as much as 22.5W, so it is appropriate for non-demanding units, however what’s attention-grabbing is the primary USB-C port as a result of it may go as much as 140W by itself. How is that attainable?
Evidently UGreen has paid a variety of consideration to the Energy Supply 3.1 know-how that turned out there not too way back. What PD 3.1 does is increase the fastened voltage to 28V, permitting energy ranges of 140W. You’ll be able to go additional because the voltage may also be 36V and 48V, permitting 180W and 240W energy output respectively.
In our case, the UGreen Nexode 140W is what may be known as an entry-level mannequin, so it nonetheless stored the scale compact. The secondary USB-C port can go as much as 100W when it is the one port in use. Should you add one other gadget to USB-C, the output of each drops to 65W every.
Additionally, utilizing both of the 2 USB-C ports at the side of the USB-A port will restrict the output to 100W (so no change for the secondary USB-C port). Should you use all three ports on the identical time, solely the 2 USB-C ports are affected, the primary taking place to 65W, whereas the second USB-C is restricted to 45W.
As for the marketed output for the primary USB-C port, it’s 5V/3A, 9V/3A, 12V/3A, 15V/3A, 20V/5A, and 28V/5A. For the secondary USB-C, it’s 5V/3A, 9V/3A, 12V/3A, 15V/3A, and 20V/5A, whereas for the USB-A port, it’s 5V/3A, 4.5V/5A, 5V /3A, 9V/2A and 12V/1.5A.
As with each different charger I’ve tried, I plugged the 140W UGreen Nexode right into a 13-inch MacBook Professional and whereas it could not attain the marketed 140W when plugged into the primary USB-C port, I noticed 56W, which it is extremely near the efficiency of Kovol 140W.
The voltage was 19.97V and the amperage ranged from 2.7 to 2.8A. There was no distinction in output between USB-C 1 and a pair of as I did not have a tool highly effective sufficient to exceed 100 W. However nonetheless I did some attention-grabbing checks.
I linked an iPhone 12 to the secondary USB-C whereas charging the MacBook Professional and it was ready to attract a mean of 21W, with voltage secure at 9.09V (amperage ranged from 2.13 to 2.17A). However I do want to say that plugging and unplugging a secondary cable into both USB-C port will trigger the opposite to energy off for a quick second and recalculate the ability output.
It is a downside while you join units that require a continuing move of energy. USB-A is just not affected and has no impression on USB-C ports, so it has a special driver. That is confirmed by the thermal photograph which exhibits that the UGreen Nexode will get a bit hotter nearer to the USB-A port and cooler subsequent to the extra highly effective USB-C ports.
There may be another factor I ought to point out and it is not likely the secondary gadget that causes charging to pause on the USB-C ports, it is the easy act of connecting a cable. For instance, I linked all three USB ports to some units, which restricted the ability output of the secondary USB-C port to 45W.
In my take a look at, it confirmed 43W, which is shut sufficient (some overload), however after unplugging the gadget from the first USB-C, whereas protecting the cable linked, there was no change within the output of the second USB-C. Because of this you shouldn’t go away cables linked to the charger as they’ll impression the output (though it sounds a bit ridiculous).
One other factor I needed to examine was whether or not the UGreen Nexode 140W charger attracts a considerable quantity of energy whereas in idle mode. I noticed that it wants round 0.05W, so nothing substantial. Lastly, I checked the ability output of the USB-A port and it averaged 9W when linked to an AGM Glory Professional. The voltage was 5.21V and the amperage ranged from 1.77 to 1.8A.
