And the world’s fastest wireless charging

OPPO宣布125瓦充電技術，可在20分鐘內將手機充滿
另外OPPO還發(fā)布了世界上最快的無線充電技術。

Oppo has long been a leader in engineering fast-charging solutions — it developed the tech behind the Dash Charge system used in OnePlus phones, for example, and has achieved even faster results in many of its own devices. Today, the company is taking a further step forward with the announcement of a 125W system that it claims is the most advanced in the industry.

長期以來，OPPO一直是快速充電解決方案的領導者，例如，一加手機中使用的Dash快充系統(tǒng)背后的技術就是由OPPO開發(fā)的，并在許多自家設備上取得了更快的充電效果。今天，該公司又向前邁進了一步，發(fā)布了一種125W的快充系統(tǒng)，OPPO聲稱這項技術是業(yè)界最先進的。

The headline figures of the system are that it can charge a 4,000mAh phone battery in 20 minutes and up to 41 percent in 5 minutes. If accurate, this would beat Oppo’s own record for fast-charging a battery of that size by around 10 minutes.

該系統(tǒng)的主要數(shù)據(jù)為：它可以在20分鐘內為一部電池容量4000mAh的手機充電，5分鐘內充進的電量高達41%。如果這種說法準確的話，這將打破OPPO自己的電池快速充電記錄，即10分鐘左右充滿41%的電量。

This isn’t simply a matter of building a big power adapter and plugging it into a regular phone — the charger, cable, and battery itself need to be designed together for safety and efficiency. Oppo says the phone, which isn’t yet a commercial product, uses double-6C cells with “breakthrough battery ratio,” while the charger benefits from improved power density properties so as not to grow too large. It uses USB-C at both ends of the cable, unlike Oppo’s previous USB-A VOOC chargers.

這并非是簡單的制作一個更大功率的適配器、并將適配器插入一部普通手機能做到的。充電器，線纜和電池本身都需要一起被重新設計，以確保安全高效。OPPO稱，該款尚未上市的手機采用的是雙6-C電芯（譯注：雙6C表示電池可以支持6倍于其容量的充放電速度），這一比例是一種突破性增長。而得益于功率密度特性的改進，充電器的體積也并沒有增加太多。OPPO在充電線兩端都使用了TYPE-C接口，與OPPO之前的手機不同，后者的VOOC充電器使用的是USB-A接口。

Oppo hasn’t announced a phone that will ship with this technology yet, but it often announces features like this before commercial products. The current fastest-charging phone in the world is the Oppo Reno Ace, which has a 4,000mAh battery that in my testing I could fully charge in 31 minutes with its 65W charger. Vivo, which shares ownership and technology with Oppo, announced 120W tech last year that can supposedly charge a 4,000mAh battery in 13 minutes, but it’s yet to ship on any phone.

OPPO尚未發(fā)布一款搭載該項技術的手機，但OPPO通常會在商業(yè)產(chǎn)品發(fā)布之前公布這樣的功能。目前世界上充電速度最快的手機是OPPO的RENO Ace，該款手機搭載了4000mAh的電池，在我的測試中，我可以用OPPO家的65W充電器、在31分鐘之內將電池充滿。VIVO公司也共享了這項技術的所有權和技術，其去年宣布推出120瓦充電技術，可以在13分鐘之內將4000mAh電池充滿，但目前還沒有任何一款支持這一技術的手機上市。

Oppo has designed a 65W AirVOOC charger, but there’s no word on when it’ll be available or when phones will support it. The lack of wireless charging was really my only major complaint with this year’s otherwise-excellent Find X2 Pro flagship, so hopefully Oppo will take the feature seriously.

OPPO已經(jīng)設計了一款65瓦功率的Airvoc充電器，但目前還沒有消息透露它什么時候上市，或者什么時候會有手機支持這項技術。無線充電的缺席、是我對今年Find X2 Pro旗艦手機的唯一抱怨之處，所以我希望OPPO能認真對待這一功能。

I always thought that such things were pointless but recently I got an OnePlus phone with a 30W charger and it’s completely changed how I plan my day wrt its battery usage. I no longer need to bring a bulky powerbank with me, and instead just pop the phone on the wall charger during short bursts whenever I sit down anywhere with a wall outlet. Still using a cheap charger at home where charging speed is not needed, and it helps battery longevity this way too.

我之前總認為快充這玩意是沒有意義的，但最近我得到了一部帶有30W快充的一加手機，它徹底改變了我每天對電池的使用計劃，我不再需要隨身攜帶一個笨重的充電寶了，不管什么時候，只要墻上有插座，我就可以坐下來、把手機插在墻插上、很短時間就充滿了。在家里不需要快速充電，我仍然使用一款便宜的充電器，這樣也有助于電池的壽命。

Why do you need to charge your phone that often? Looks like that tech is seriously degrading your battery, or the phone is laughably inefficient in the first place. I for one charge mine every 1.5 days. And i use it all day.

為什么你需要經(jīng)常給手機充電呢？貌似這項技術會嚴重降低了你的電池性能，或者說你手機的效率本身就很低。我每1.5天才給我的手機充電一次，而且我一整天都在用。

I travel a lot for work so there are often long stretches of the day where I’m just sitting somewhere doing nothing but working/playing on my phone, and having a fast charger to plug on the train/plane’s power outlet is a godsend.

“為什么你需要經(jīng)常給手機充電呢？”---
由于工作我要經(jīng)常出差，所以一天中有很長時間我只能坐在某個地方，除了工作或玩手機，我什么也不做。擁有一個快充、插在火車或飛機的電源插座上，這真是雪中送炭。

Charging phone multiple times a day sounds like a pain, I guess if you’re a super heavy user can’t escape it, but to me I want a long lasting battery so that I don’t even need to think about charging, just plug it overnight (or even better use wireless charging) every night and forget about it.

一天中多次給手機充電聽起來很是痛苦，但我想，如果你是一個超級重度的手機用戶，你是無法逃避這個問題的。不過對于我來說，我想要的是一塊持久的電池，這樣我甚至不需要考慮充電的問題，只需每天晚上插上充電器（用無線充電就更好了），然后就啥都不用管了。

sounded like a step backwards for me too, and I absolutely hate to look around for outlets, even if it’s quick, having my stuff laying around like that is a no go to me
OTOH I really like the idea for my powerbank, I don’t mind degradation on it and being able to top it off in an emergency sound useful

對于我來說，這聽起來也像是一種倒退，我絕對不喜歡四處尋找電源插座，即使它充電很快，讓我四處亂放東西、對我來說是不可能的。
另一方面，我真的很喜歡我的充電寶，我不介意攜帶充電寶，它能在緊急情況下把手機充滿，聽起來很有用。

I wonder if a small fan would stop the heating issue. Not suggesting consumers should buy one, but that they should be integrated into the charging mechanisms.

我不知道一個小風扇是否能解決發(fā)熱的問題，我不是建議消費者去買一個小風扇，但他們應該把風扇集成到充電器里才行。

As least with OnePlus phones, all the voltage modulation happens in the charger, not in the phone. So the phone never gets unusually hot.

至少在一加手機上，所有的電壓調制都是在充電器內部實現(xiàn)的，所以手機不會變得異常的熱。

That’s strange, because I have the same setup and I have done multiple long road trips with my phone sitting on the wireless charger with no issues.

奇了怪了，因為我也有跟你一樣的設備，而且我也進行過多次長途旅行，手機就放在無線充電器上，并沒有啥問題呀。

4000mAH x 3.7v = 14.8WH
14.8WH x 0.41 = ~6WH
6WH ÷ 5/60 = ~75W
It’s 50% efficient. You’re burning as much power as waste heat as you’re actually putting into the phone.
4000mAH x 3.7v = 14.8WH
14.8WH x 0.41 = ~6WH
6WH ÷ 5/60 = ~75W

這效率才50%，當你插上手機充電時，發(fā)熱和你消耗的能量一樣多。

vaguely_human
Also I’m betting quite a lot of that is getting dumped right into the phone, because 50% efficiency on the power supply itself would be downright embarrassing.

另外，我敢打賭，相當多的熱量會直接進入手機，因為電源本身50%的效率會讓人很尷尬的。

vaguely_human
lol that’s not 50%. but I stand by that efficiency being shitty and unjustifiably wasteful.

哈哈哈，算錯了效率不是50%，但我堅持認為，這種效率是低下的，這就是毫無意義的浪費。

4000mAh x 3.7v = 14.8Wh
125W * 20/60h = 41.667Wh

14.8Wh/41.667Wh = 35.52% 的效率
（譯者注：這倆根本沒有常識，首先電池充電過程中平均電壓不能以3.7V來計算，另外125W說的是最大功率，充電過程中并不一定要吃滿功率，而是電池容量越大，分配的功率越多。比如電池容量是1000mAh，如果以125W來充電，則充電功率高達125/(4.0*1)=31.25C，那么電池早爆炸了，沒有任何一款電池能撐得住如此高的倍率（就算OPPO也只說了6C而已）。）

Yeah i really don’t see a point in having a charger that can literally charge a laptop like okay it can charge your phone fast but the majority of people who don’t think about battery degradation due to charging will leave it overnight charging.
I might pick one up for my XPS since it uses a 130w barrel charger but ive been looking for something more compact.

是的，我真的不認為這樣一個充電器有啥意義，這玩意都可以充一臺筆記本電腦了。沒錯，它充手機是很快，但大多數(shù)人不會考慮充電過程導致的電池退化，他們都會充一夜的電。
我可能會為我的XPS筆記本電腦挑選一個這樣的充電器，因為它使用的是一個很大的130瓦適配器，但我一直在尋找更加緊湊的充電器。

I’m certainly concerned about this as well, but it is worth mentioning that battery tech doesn’t just sit around. Batteries have gotten better over time. Are they this good now? I really doubt it, but we will see…

當然了，我也很關心這個問題，但值得一提的是，電池技術也不是坐以待斃的。隨著時間的推移，電池變得更好了。
但現(xiàn)在的電池已經(jīng)這么厲害了嗎？我真的很懷疑，但我們拭目以待吧…

This will wreck battery longevity. Instead of all this garbage how about giving me a phone 4mm thicker that actually has a decent sized battery so I don’t have to charge it all the time.

這會破壞電池壽命的。與其推出這樣的垃圾功能，不如給我來一臺加厚4mm的手機，這樣手機電池容量就相當大了，這樣我也不用一直給它充電了。

I’m sure these companies are investing millions of dollars in R&D to produce "all this garbage" and entire teams of engineers didn’t think once about "wrecking battery longevity".
Mr. Icebox in the comments section has it all figured out, would no one listen to him? Give him a brick, fire all the engineers and shut down all r&d.. we’re done with innovation and progress, Mr. Icebox had found the answer to the universe.

我確信這些公司在研發(fā)上投入了數(shù)百萬美元、用來生產(chǎn)所有這些所謂的“垃圾”，而整個工程師團隊都沒有考慮過它會“破壞電池壽命”？
評論區(qū)的那位Icebox先生已經(jīng)指出了，難道沒有人聽他的嗎？給他一臺磚頭手機，解雇所有的工程師，關閉所有的研發(fā)。。。我們已經(jīng)完成了創(chuàng)新和進步，Icebox先生已經(jīng)找到了宇宙的奧秘了。

No way will this phone last any meaningful amount of time. 125W for ~16Wh battery? Ridiculous.

I think there is a reason nobody else does this. It’s not rocket science either. Either these guys have broken physics or they’re making sacrifices. My money is on the latter. There is no way you’re pushing 125W to small batteries without something (longevity, efficiency…) giving in between.
So they may not be kids, but I’m not banking any money on them either.

我想，別的廠家沒有這樣做是有原因的。這也不是火箭科學，要么這些人打破了物理原理，要么他們會付出代價，我打賭是后者。你不可能在沒有妥協(xié)的情況下（如電池壽命、效率……）、將125W用在小型電池上。
他們可能不是小孩子，但我也不會把錢花在他們身上。

I really want that, on my powerbank, I don’t mind its degradation and it usually takes much longer to charge because of the amount of power
