You should have checked the transformers, and how well the windings are electrically separated. My primary concern for anything I plug into wall sockets is that it doesn't burn down my house.
Oof. Peak temperature of ~80C on the case; probably at least 10 degrees hotter inside. That's pushing uncomfortably close to the temperature rating of those capacitors. I hope it has a temperature sensor to limit power if it overheats on a hot day.
I got a couple 511 last year after getting an iPhone 15 and needing more USB-C gear. Been very happy with them. I don't think I've ever been even remotely disappointed with Anker kit.
please compare Anker Prime 100W GaN 3-port compact fast PPS Charger vs UGREEN Nexode Pro 100W 3-Port GaN Compact Fast PPS Charger - it's the latest ones and much more useful than the 30w baby ones you've done here - outstanding analysis and work by you.
I'd also like to see a disassembly of the Nexode Pro 65W, specifically the "Ultra-Slim" version. I have one and it definitely gets toasty under full load, although for me it's not as much of a concern since I mainly keep it in my backpack as a spare so size and form factor is paramount. I'd be hesitant to use it behind a desk or in an area that isn't well ventilated, though. It would actually be good to see some effort put into building chargers *specifically* designed for enclosed/hot conditions, using the most efficient technology but combining it with intentionally overkill cooling.
there is a TH-cam channel called allthingsoneplace that does complete technical testing of usb c chargers he tests these two chargers & they are virtually the same chargers except for the price, the ugreen are lower priced.
Great teardown, I'm disappointed at the choice of electrolytic capacitors by both brands chengx and capxon. Capxon has generally had a bad reputation back when I was designing PCBs in particular with power supplies where they would fail within a couple of years.
I feel the same. Although Chengx and Capxon both offer special OEM batches, Capxon capacitors tend not to perform in a steady way. Leakage at high temp is a nightmare. I may go with Anker for the component durability.
@@tenminutesafterdrawing there was a company we bought PSUs from that switched out Rubicon caps for capxon and all of a sudden our kit started failing. After analysis we realised when it was warm in the summer the capxon caps started failing 'bulging' like they were going to vent.
Thank you Otaku. I've recommended your channel to our office manager. My offices have both, about 50 in total. And I could never tell the differences. Now, my four-year old question finally got an answer. If you have a chance, could you do a similar comparison of Thunderbolt 3 or Thunderbolt 4 cables? For example, the two manufacturers in your video are also making those cables. Both seem very reputable, also, with big differences in price. We have a lot of accessories around, can mail you some for sure! And please keep them whether you decide to test them or not. Please accept them as our gratitude. (I must say that your video voiceover is one of the best! It's so hard to do, especially with perfect timing.) ありがとう ございます😃😃
I wonder whether the smaller, hotter charger will stop working sooner, or perhaps it will last long enough for the owner to lose it before that is an issue. Personally, I usually keep my chargers at home so a small difference in size is not worth paying extra, and especially not worth a decrease in longevity.
i have the ugreen 45watt version has dual ports. i love it. fantastic charger. was a little pricy i think i paid $40 usd if i remember. i recommend it to anyone. never had any issue. i will test it further to see what i can post here. i do see the output info. 5v,3A - 9v,3A - 12v,3A - 15v,3A - 20V,2.25A and 3.3-11V @4.05A 45WATT max. hope this helps. model CD284. awesome video by the way. thank you sooo much for this detail video.
Did you measure the frequency of the chargers under load? I would expect a significantly higher switching frequency, from 1 to 2 MHz. I believe you were seeing the frequency in the chargers pulse skipping mode that they enter under very low load
A given current results in lower dissipation traveling a shorter distance for an equivalent trace width and thickness. Bottom line, circuit board size and current capacity, measured alone, have no relationship. 100A could safely flow in a 22AWG wire if it’s short enough.
Heat is the enemy of reliability. I prefer Anker as a brand but would choose Ugreen specifically for the lower operating temperature if I were in the market for this product. 80C is high enough I would expect to be able to smell it, and that measurement is in free air. Not good.
If you want one that isn't going to break after a few months get the anker. Cheap Chinese shit might meet the same specs. But will break almost immediately. That's one hundred percent of the time. Will not fail.
Thank you to the translator also; literacy in two very different languages is an achievement.

Not 10 I expect the die to be at 130

My 100w caught “fire”, it was smoldering at the usb port and also over heated the other end, almost killed my beats headphones

厳密な分析をありがとうございます。より低い温度で動作するため、より大きなデバイスの方が好ましいです。
Thanks for the video, for me the significantly lower temperature alone, makes the Ugreen an easy choice, even if it is slightly larger.

I picked up the Anker nano 3 on sale from Amazon. Their website lists it as
GaN. Great charger I use it for travel.
Thank you Otaku.

It's hard to find videos like this, TH-cam sucks

This is an excellent review and break down! My question: Is it quiet enough to power a preamp for an audio system? Thank you.
Your videos are like greatscott❤
OMG I'm obsessed with phone cameras 😮
Seeing the actual sensor is wild.
I wonder gow it is in comparison with aps-c camera sensors 🤔
A little disappointed you do not disassemble the transformer, but I assume they're both high quality.
It was informative, but you should mention ripples of output voltage.
Did you measure the frequency of the chargers under load? I would expect a significantly higher switching frequency, from 1 to 2 MHz. I believe you were seeing the frequency in the chargers pulse skipping mode that they enter under very low load
I think Anker the best and number one
Very interesting, thank you very much!
Thanks. I don't understand Japanese so English dub video helps a lot
I can't wait to see what the 100W+ chargers look like inside. That's an awful lot of amps to run through a tiny circuit board.
A given current results in lower dissipation traveling a shorter distance for an equivalent trace width and thickness. Bottom line, circuit board size and current capacity, measured alone, have no relationship. 100A could safely flow in a 22AWG wire if it’s short enough.
My 100w anker was smoldering at the usb c port… killed it
Tx.Bro.
Good
Luck
The capacitors on the secondary of both of those chargers look like SOLID POLYMER to me, not electrolytics
thank you
This video is translated, and auto dubbed. Interesting

Nice
In my opinion, ugreen seems safer
My anker usb c fried itselft, it was smoldering at the port…
.👍👍👍

Transformer autopsy and insulation quality review is missong.
Don't buy Xiaomi
Sizs and weight is complete irrelevanr
If your not japanese, please let me know so i could unsub.
