And the world’s fastest wireless charging

OPPO宣布125瓦充电技术，可在20分钟内将手机充满

另外OPPO还发布了世界上最快的无线充电技术。

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.

长期以来，OPPO一直是快速充电解决方案的领导者，例如，一加手机中使用的Dash快充系统背后的技术就是由OPPO开发的，并在许多自家设备上取得了更快的充电效果。今天，该公司又向前迈进了一步，发布了一种125W的快充系统，OPPO声称这项技术是业界最先进的。

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.

该系统的主要数据为：它可以在20分钟内为一部电池容量4000mAh的手机充电，5分钟内充进的电量高达41%。如果这种说法准确的话，这将打破OPPO自己的电池快速充电记录，即10分钟左右充满41%的电量。

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.

这并非是简单的制作一个更大功率的适配器、并将适配器插入一部普通手机能做到的。充电器，线缆和电池本身都需要一起被重新设计，以确保安全高效。OPPO称，该款尚未上市的手机采用的是双6-C电芯（译注：双6C表示电池可以支持6倍于其容量的充放电速度），这一比例是一种突破性增长。而得益于功率密度特性的改进，充电器的体积也并没有增加太多。OPPO在充电线两端都使用了TYPE-C接口，与OPPO之前的手机不同，后者的VOOC充电器使用的是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尚未发布一款搭载该项技术的手机，但OPPO通常会在商业产品发布之前公布这样的功能。目前世界上充电速度最快的手机是OPPO的RENO Ace，该款手机搭载了4000mAh的电池，在我的测试中，我可以用OPPO家的65W充电器、在31分钟之内将电池充满。VIVO公司也共享了这项技术的所有权和技术，其去年宣布推出120瓦充电技术，可以在13分钟之内将4000mAh电池充满，但目前还没有任何一款支持这一技术的手机上市。

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已经设计了一款65瓦功率的Airvoc充电器，但目前还没有消息透露它什么时候上市，或者什么时候会有手机支持这项技术。无线充电的缺席、是我对今年Find X2 Pro旗舰手机的唯一抱怨之处，所以我希望OPPO能认真对待这一功能。

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.

我之前总认为快充这玩意是没有意义的，但最近我得到了一部带有30W快充的一加手机，它彻底改变了我每天对电池的使用计划，我不再需要随身携带一个笨重的充电宝了，不管什么时候，只要墙上有插座，我就可以坐下来、把手机插在墙插上、很短时间就充满了。在家里不需要快速充电，我仍然使用一款便宜的充电器，这样也有助于电池的寿命。

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.

为什么你需要经常给手机充电呢？貌似这项技术会严重降低了你的电池性能，或者说你手机的效率本身就很低。我每1.5天才给我的手机充电一次，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.

“为什么你需要经常给手机充电呢？”---

由于工作我要经常出差，所以一天中有很长时间我只能坐在某个地方，除了工作或玩手机，我什么也不做。拥有一个快充、插在火车或飞机的电源插座上，这真是雪中送炭。

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.

一天中多次给手机充电听起来很是痛苦，但我想，如果你是一个超级重度的手机用户，你是无法逃避这个问题的。不过对于我来说，我想要的是一块持久的电池，这样我甚至不需要考虑充电的问题，只需每天晚上插上充电器（用无线充电就更好了），然后就啥都不用管了。

moromi_ken

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

对于我来说，这听起来也像是一种倒退，我绝对不喜欢四处寻找电源插座，即使它充电很快，让我四处乱放东西、对我来说是不可能的。

另一方面，我真的很喜欢我的充电宝，我不介意携带充电宝，它能在紧急情况下把手机充满，听起来很有用。

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.

我不知道一个小风扇是否能解决发热的问题，我不是建议消费者去买一个小风扇，但他们应该把风扇集成到充电器里才行。

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

至少在一加手机上，所有的电压调制都是在充电器内部实现的，所以手机不会变得异常的热。

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，因为我也有跟你一样的设备，而且我也进行过多次长途旅行，手机就放在无线充电器上，并没有啥问题呀。

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

这效率才50%，当你插上手机充电时，发热和你消耗的能量一样多。

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，我敢打赌，相当多的热量会直接进入手机，因为电源本身50%的效率会让人很尴尬的。

vaguely_human

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

哈哈哈，算错了效率不是50%，但我坚持认为，这种效率是低下的，这就是毫无意义的浪费。

Heat is one of the main things that destroys battery capacity over time.

随着时间的推移，发热是破坏电池容量的主要因素之一。

4000mAh x 3.7v = 14.8Wh

125W * 20/60h = 41.667Wh

14.8Wh/41.667Wh = 35.52% 的效率

（译者注：这俩根本没有常识，首先电池充电过程中平均电压不能以3.7V来计算，另外125W说的是最大功率，充电过程中并不一定要吃满功率，而是电池容量越大，分配的功率越多。比如电池容量是1000mAh，如果以125W来充电，则充电功率高达125/(4.0*1)=31.25C，那么电池早爆炸了，没有任何一款电池能撑得住如此高的倍率（就算OPPO也只说了6C而已）。）

You mean like the dust these batteries are turning into after using this for extended periods of time? That dust?

你的意思是说，长时间使用这种快充、电池会变成灰烬么？

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，我真的不认为这样一个充电器有啥意义，这玩意都可以充一台笔记本电脑了。没错，它充手机是很快，但大多数人不会考虑充电过程导致的电池退化，他们都会充一夜的电。

我可能会为我的XPS笔记本电脑挑选一个这样的充电器，因为它使用的是一个很大的130瓦适配器，但我一直在寻找更加紧凑的充电器。

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…

当然了，我也很关心这个问题，但值得一提的是，电池技术也不是坐以待毙的。随着时间的推移，电池变得更好了。

但现在的电池已经这么厉害了吗？我真的很怀疑，但我们拭目以待吧…

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.

这会破坏电池寿命的。与其推出这样的垃圾功能，不如给我来一台加厚4mm的手机，这样手机电池容量就相当大了，这样我也不用一直给它充电了。

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.

我确信这些公司在研发上投入了数百万美元、用来生产所有这些所谓的“垃圾”，而整个工程师团队都没有考虑过它会“破坏电池寿命”？

评论区的那位Icebox先生已经指出了，难道没有人听他的吗？给他一台砖头手机，解雇所有的工程师，关闭所有的研发。。。我们已经完成了创新和进步，Icebox先生已经找到了宇宙的奥秘了。

I am interested in ultra fast charging as a phenomenon, but would not buy a phone just for that feature. I wonder if they will grenade better than that other brand ?!

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

这部手机不可能持续太长时间，用125瓦来给16Wh的手机充电？这太荒谬了。

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，别的厂家没有这样做是有原因的。这也不是火箭科学，要么这些人打破了物理原理，要么他们会付出代价，我打赌是后者。你不可能在没有妥协的情况下（如电池寿命、效率……）、将125W用在小型电池上。

他们可能不是小孩子，但我也不会把钱花在他们身上。
