Being able to quickly charge your phone or tablet can mean the difference between hours of care-free use or scrambling to find the nearest coffee shop for a power outlet. Fast charging is an increasingly popular feature that allows you to power up your device in just a fraction of the time it takes to do it the old-fashioned way. But not all products use the same type of fast charging-and not all chargers support the various standards. Here’s what you need to know to make sure you’re getting the fastest charge possible.

能够为手机或平板电脑快速充电可能意味着免时间使用小时或争先恐后地寻找最近的咖啡店作为电源插座之间的区别。 快速充电是一种越来越流行的功能，它使您能够以老式方式为设备加电的一小部分。 但是，并非所有产品都使用相同类型的快速充电-并非所有充电器都支持各种标准。 这是您需要知道的，以确保您获得最快的充电速度。

了解快速充电 (Understanding Fast Charging)

The output of a charge is measured in amperage and voltage. Amperage (or current) is the amount of electricity flowing from the battery to the connected device, while voltage is the strength of the electric current. Multiplying volts by amps gives you wattage, the measure of total power.

电荷的输出以安培数和电压为单位。 安培(或电流)是从电池流向所连接设备的电量，电压是电流的强度。 伏特乘以安培可得到瓦特数，即总功率的度量。

To make a device charge faster, most manufacturers either boost the amperage or vary the voltage in order to increase the amount of potential energy. The majority of fast charging standards typically vary the voltage rather than boost the amperage.

为了使设备充电更快，大多数制造商要么提高安培数，要么改变电压以增加势能。 大多数快速充电标准通常会改变电压而不是提高安培数。

Standard USB 3.0 ports output at a level of 5V/1A for smaller devices like wearables. Most phones and other devices are capable of handling 5V/2.4A. For fast charging, you’re looking at something that bumps the voltage up 5V, 9V, 12V, and beyond, or increases amperage to 3A and above.

标准USB 3.0端口以5V / 1A的电平输出，用于可穿戴设备等较小的设备。 大多数电话和其他设备都能够处理5V / 2.4A。 对于快速充电，您正在寻找使电压升高5V，9V，12V及更高电压，或将安培数提高至3A及更高电压的产品。

Keep in mind, your device will only take in as much power as its charging circuit is designed for. For fast charging to work, you need a phone or other device with a charging circuit capable of using one of the fast charging standards, and an adapter and cable enabled for that same standard.

请记住，您的设备仅会吸收其充电电路所设计的电量。 为了使快速充电正常工作，您需要一部电话或其他设备，其手机具有能够使用快速充电标准之一的充电电路，并为该标准启用了适配器和电缆。

快速充电类型 (Type of Fast Charging)

苹果快速充电 (Apple Fast Charging)

Starting with the iPhone 8, all of Apple’s phones support fast charging. Unless you own an iPhone 11 Pro or 11 Pro Max, however, you’re probably using one of Apple’s slow 5W adapters to charge your phone.

从iPhone 8开始 ，所有苹果手机都支持快速充电 。 但是，除非您拥有iPhone 11 Pro或11 Pro Max ，否则您可能正在使用Apple的5W慢速适配器之一为手机充电。

Apple uses USB Power Delivery for fast charging, and claims you’ll see a 50 percent increase in battery life in just 30 minutes. In order to get these speeds, however, you need to use at least an 18W adapter with a USB-C-to-Lightning cable. A more powerful adapter won’t harm your phone, but it’s unlikely to help. We reached out to Apple to determine the most powerful adapter its iPhone lineup will support, but a representative for the company said it doesn’t disclose maximum charging specifications.

苹果使用USB Power Delivery进行快速充电，并声称您将在30分钟内将电池寿命增加50％。 但是，为了获得这些速度，您至少需要使用18W适配器和USB-C至Lightning电缆。 功能更强大的适配器不会损坏您的手机，但不太可能有所帮助。 我们与苹果公司联系，以确定其iPhone产品线将支持的最强大的适配器，但该公司的一位代表表示，它没有透露最大充电规格。

联发科技Pump Express (MediaTek Pump Express)

Certain MediaTek-powered phones use the company’s Pump Express standard, which comes in different versions on different devices.

某些由MediaTek支持的电话使用公司的Pump Express标准，该标准在不同设备上具有不同版本。

Pump Express 2.0+ is primarily for MediaTek’s low-end chipsets, and works with micro USB and USB-C charging ports. Charging maxes out at 15W by using 5V to 20V variable voltage in conjunction with 3A or 4.5A of current.

Pump Express 2.0+主要用于联发科的低端芯片组，并与micro USB和USB-C充电端口配合使用。 通过使用5V至20V可变电压以及3A或4.5A电流，充电可在15W时达到最大。

Pump Express 3.0 and Pump Express 4.0 are largely the same. Both rely on 5A of current and use USB Power Delivery 3.0. The difference is that Pump Express 4.0 also supports its own proprietary wireless charging technology, as well at Qi wireless charging at 5W.

Pump Express 3.0和Pump Express 4.0基本相同。 两者都依靠5A电流并使用USB Power Delivery 3.0。 不同之处在于Pump Express 4.0还支持其自己的专有无线充电技术，以及5W的Qi无线充电功能。

MediaTek claims Pump Express 2.0+ should charge a depleted battery to 70 percent within 30 minutes, while Pump Express 3.0 and 4.0 should cut that time in half. While these are indeed fast estimates, we didn’t quite see these results bear our when testing Pump Express 3.0. On average, we saw closer to a 55 percent charge over 15 minutes, which is still nothing to sneeze at.

联发科声称Pump Express 2.0+应该在30分钟内将电量耗尽的电池充电到70％，而Pump Express 3.0和4.0应该将时间缩短一半。 尽管这些确实是快速的估计，但在测试Pump Express 3.0时，我们并没有看到这些结果能满足我们的要求。 平均而言，我们发现15分钟内的充电率接近55％，这仍然是不容小的。

OnePlus Dash费用和Warp费用 (OnePlus Dash Charge and Warp Charge)

Dash Charge and Warp Charge are licensed from Oppo, and work the same as Vooc, bumping up amperage to 5V/4A to achieve an output of 20W. On a phone like the OnePlus 5T, you can charge up to 60 percent in 30 minutes.

Dash Charge和Warp Charge是由Oppo许可的，其工作原理与Vooc相同，将安培数提高到5V / 4A，以实现20W的输出。 在像OnePlus 5T这样的手机上，您可以在30分钟内为多达60％的手机充电。

Newer models like the OnePlus 8 Pro support 30W wired and wireless charging thanks to Warp Charge. Wired charging is delivered via a 5V/6A adapter and proprietary USB-C cable. Delivering 30W wireless charging speeds is more of a challenge, as it would create an extraordinary amount of heat using the standard 5V/6A formula. Instead, OnePlus delivers 20V at just 1.5A, since voltage creates far less heat.

由于Warp Charge，像OnePlus 8 Pro这样的较新型号支持30W有线和无线充电。 有线充电通过5V / 6A适配器和专有的USB-C电缆进行。 提供30W无线充电速度更具挑战性，因为使用标准5V / 6A公式会产生大量热量。 相反，OnePlus仅以1.5A的电流提供20V电压，因为电压产生的热量少得多。

OnePlus also uses charge pumps in an innovative way to make charging safer and more efficient. If you really want to dig into the nuts and bolts of OnePlus’ 30W wireless charging, check out Android Central’s explainer.

OnePlus还以创新的方式使用电荷泵，以使充电更安全，更高效。 如果您真的想深入研究OnePlus 30W无线充电的细节，请查看Android Central的解释器 。

Oppo SuperVooc闪光灯充电 (Oppo SuperVooc Flash Charge)

Vooc is Oppo’s proprietary fast charging standard. The company has long been a leader in fast charging technology, and it currently holds the record for fastest charging speed with its 65W adapter that can fully charge the Reno Ace in just 31 minutes. In addition, Oppo is the only major manufacturer to use gallium nitride (GaN) batteries in its phones for better performance and reliability.

Vooc是Oppo专有的快速充电标准。 该公司长期以来一直是快速充电技术的领导者，目前其65W适配器保持了最快充电速度的记录 ，该适配器可在短短31分钟内为Reno Ace充满电。 此外，Oppo是唯一在手机中使用氮化镓(GaN)电池以提高性能和可靠性的主要制造商。

Oppo’s SuperVooc comes in several different flavors. The fastest is SuperVooc 2.0, which uses 10V and 6.5A to charge its phones at 65W. SuperVooc comes in at an impressive 50W maximum charge by combining 10V of electrical force and 5A of power. Vooc is the slowest of the bunch, with a maximum charging speed of 25W at 5V/5A.

Oppo的SuperVooc有几种不同的口味。 最快的是SuperVooc 2.0 ，它使用10V和6.5A为65W的手机充电。 通过将10V的电力和5A的功率相结合，SuperVooc能够以令人印象深刻的50W最大电荷充电。 Vooc是最慢的，在5V / 5A时最大充电速度为25W。

In order to achieve such high speeds, Oppo phones require both a special USB-C cable and adapter.

为了达到如此高的速度，Oppo手机需要专用的USB-C电缆和适配器。

高通快速充电 (Qualcomm Quick Charge)

The most common fast charging standard is Qualcomm’s Quick Charge because of the widespread nature of the company’s chipsets. That said, many of the phones that support newer Quick Charge standards aren’t sold in the US.

由于公司芯片组的广泛性，最常见的快速充电标准是高通公司的快速充电 。 也就是说，许多支持较新的Quick Charge标准的手机在美国并未销售。

Quick Charge 3.0 is one of the most common fast charging protocols used in older flagships, and Quick Charge 3+ brings similar speeds to midrange phones with some Qualcomm Snapdragon 700-series chipsets. Quick Charge 4+ is the global gold standard for flagships that don’t use proprietary fast charging technologies. Each standard is backward compatible with the previous one, so older cables and adapters will still work.

Quick Charge 3.0是较早的旗舰产品中使用的最常见的快速充电协议之一，而Quick Charge 3+为具有某些Qualcomm Snapdragon 700系列芯片组的中端手机带来了相似的速度。 快速充电4+是不使用专有快速充电技术的旗舰店的全球黄金标准。 每个标准都与先前的标准向后兼容，因此较旧的电缆和适配器仍然可以使用。

Quick Charge 3.0 dynamically boosts voltage from 3.2V to 20V, though peak power for both standards is 18W. That means, theoretically, phones with a 3,500mAh to 4,500mAh capacity can gain about 80 percent charge in just 35 minutes when the battery is depleted. Quick Charge 3+ brings similar charging speeds to less-expensive chipsets.

尽管两种标准的峰值功率均为18W，但Quick Charge 3.0仍可将电压从3.2V动态提升至20V。 从理论上讲，这意味着电量为3,500mAh至4,500mAh的手机在电池耗尽后仅需35分钟即可获得约80％的电量。 Quick Charge 3+为便宜的芯片组带来了类似的充电速度。

Quick Charge 4+ narrows the voltage range while pumping up the amperage. It offers 5V at between 4.7A to 5.6A, or 9V at 3A. Quick Charge 4+ devices use USB-C ports and are compliant with USB Power Delivery. They also have a second power management chip, allowing up to 28W of power without overheating. The LG V60 ThinQ 5G is one of a handful of US phones that support Quick Charge 4+, and in testing, we were able to get a 50 percent charge on a depleted battery in about 18 minutes.

快速充电4+可在增加电流时缩小电压范围。 它在4.7A至5.6A之间提供5V电压，在3A时提供9V电压。 Quick Charge 4+设备使用USB-C端口并符合USB Power Delivery。 它们还具有第二个电源管理芯片，可提供高达28W的功率而不会过热。 LG V60 ThinQ 5G是少数支持Quick Charge 4+的美国手机之一，在测试中，我们能够在大约18分钟的时间内用完耗尽的电池获得50％的电量。

三星自适应快速充电 (Samsung Adaptive Fast Charging)

Samsung’s Adaptive Fast Charging works in a similar manner to Qualcomm’s Quick Charge by bumping up voltage and/or amperage. Samsung doesn’t release all the specifications for its Adaptive Fast Charging protocol, nor does it make any claims about charging times, but it provided us with some speed and support information in the charts below.

三星的自适应快速充电通过提高电压和/或安培数而与高通的快速充电类似。 三星并未发布其自适应快速充电协议的所有规范，也未对充电时间做出任何声明，但三星在下表中向我们提供了一些速度和支持信息。

With Samsung’s optional 10V/4.5W adapter, the Galaxy S20 Ultra and the Note 10+ can theoretically charge at 45W. Most of Samsung’s current-generation flagships support Adaptive Fast Charging up to 25W with the adapter in the box. It’s important to note that while some Samsung phones support older versions of Qualcomm Quick Charge, you’ll see much faster speeds using the adapter that comes with the phone or a Samsung-certified adapter.

使用三星可选的10V / 4.5W适配器， Galaxy S20 Ultra和Note 10+理论上可以以45W充电。 三星当前的大多数旗舰产品都通过包装盒中的适配器支持高达25W的自适应快速充电。 重要的是要注意，尽管某些三星手机支持旧版的Qualcomm Quick Charge，但使用手机随附的适配器或三星认证的适配器，您会看到更快的速度。

什么是无线快速充电？ (What Is Wireless Fast Charging?)

Wireless charging is convenient, but it can be slow. Most wireless chargers that lack fans or cooling systems are limited to charging speeds of just 5V/1A. But various companies now offer fast wireless charging pads that come with built-in fans to dissipate heat, allowing you to charge at speeds nearly on par with a cable.

无线充电很方便，但速度可能很慢。 大多数缺少风扇或冷却系统的无线充电器的充电速度仅限于5V / 1A。 但是，现在许多公司都提供了带有内置风扇的快速无线充电板来散热，使您可以以几乎与电缆相当的速度进行充电。

Voltage and amperage depend on the charging pad in question. Once again, you’ll want to make sure that your phone and your wireless charging pad support the same fast charging standard. Also keep in mind you’ll need a wall adapter plugged into the pad that supports fast charging as well.

电压和安培数取决于所讨论的充电垫。 再次，您需要确保手机和无线充电板支持相同的快速充电标准。 另外请记住，您需要将墙上适配器插入垫中，以支持快速充电。

There are lots of variables to think about when buying a wireless charger, so we’ve done the homework for you by creating a list of the best wireless charging pads based on your phone and budget.

购买无线充电器时，需要考虑很多变量，因此我们根据您的手机和预算创建了一个最佳无线充电板列表，为您完成了作业。

手机以外的快速充电 (Fast Charging Beyond Your Phone)

For laptops, the fast charging situation is a bit different. USB Power Delivery (PD) isn’t so much fast charging as it is a standard that determines if an adapter or portable power bank is capable of charging a laptop or other high-powered device. With USB-C input/output ports now pretty much standard, it’s possible for adapters and power banks to charge devices that require an output of 18W or more. The Power Delivery spec allows a device to be charged at a maximum current of 5A or 100W.

对于笔记本电脑，快速充电情况有所不同。 USB Power Delivery (PD)并不是快速充电，而是一种标准，它确定适配器或便携式移动电源是否能够为笔记本电脑或其他大功率设备充电。 如今，USB-C输入/输出端口已经成为标准配置，适配器和移动电源可以为需要输出18W或更高功率的设备充电。 Power Delivery规范允许设备以5A或100W的最大电流充电。

Power Delivery 3.0 is quickly becoming the standard for power banks and adapters. It supports outputs at 7.5W, 15W, 27W, and 45W, each with its own voltage and amperage configurations. This means PD adapters with multiple USB-C ports can intelligently dole out power to multiple devices, so a 45W adapter may supply 18W to charge your phone, 5W to a wearable, and the remaining 22W to a tablet.

Power Delivery 3.0Swift成为移动电源和适配器的标准。 它支持7.5W，15W，27W和45W的输出，每个输出都有自己的电压和安培数配置。 这意味着具有多个USB-C端口的PD适配器可以智能地为多个设备分配电源，因此45W适配器可以提供18W的功率为您的手机充电，为5W的功率为可穿戴设备充电，其余的22W的功率为平板电脑。

快速充电需要什么 (What You Need for Fast Charging)

Depending on the device you have, the fast charging standard you’re able to use will vary. Check what your phone supports, then look at your wall adapter to see if it supports the same standard (they’re usually labeled). Then make sure your cable is compatible (you’re best off using one the one that come with your phone or adapter). If you need to buy a new wall adapter, cable, or wireless charging pad, take note of what standard it supports.

根据您使用的设备，您可以使用的快速充电标准会有所不同。 检查您的手机支持什么，然后查看壁式适配器以查看其是否支持相同的标准(通常标有标签)。 然后确保电缆兼容(最好使用电话或适配器随附的电缆)。 如果您需要购买新的墙上适配器，电缆或无线充电板，请注意其支持的标准。
