USB Power Delivery: The fastest way to charge your iPhone and Android device

Published

With the introduction of the iPhone 8 and now the iPhone XS/Max and soon to be delivered XR, with their much faster processors and vivid high-resolution displays and always-on connectivity, demands on battery performance are now higher than ever before.

As a recent owner of one of these devices, you may have noticed that while you are on the road, you’re running out of juice quickly. So you’re probably going to need to invest in a portable battery and a faster wall charger.

But not all portable batteries are the same, despite the fact that they might use similar Lithium Polymer (LiPo) and Lithium Ion (Lion) cells for capacity and look very much alike.

Modern smartphone hardware from Apple and various Android manufacturers support much faster charging rates than what was previously supported.

But if you use the charger that comes in the box with the current generation iPhone hardware, or if you just simply buy just any portable battery pack on the market, you’re going to be disappointed.

Ideally, you want to match your charger, battery and even the charging cable to the optimal charging speeds that your device supports.

There are three different high-speed USB charging standards currently on the market, and while all of them will work with your device using a common legacy charge mode, you will ideally want to match up the correct technology in order to optimize the speed in which you can top off your phone, tablet, or even your laptop.

Let’s start by explaining the differences between them.

Legacy USB-A 2.0 and 3.0 charging

If your Android device has the USB Micro B connector (the dreaded fragile trapezoid that’s impossible to connect in the dark) you can fast charge it using an inexpensive USB-A to USB Micro B cable.

If the device and the charge port both support the USB 2.0 standard (pretty much the least common denominator these days for entry-level Android smartphones) you can charge it at 1.5A/5V.

Some consumer electronics, such as higher-end vape batteries that use the Evolv DNA chipset can charge at 2A.

A USB 3.0/3.1 charge port on one of these batteries can supply 3.0A/5V if the device supports it.

If you are charging an accessory, such as an inexpensive pair of wireless earbuds or another Bluetooth device, and it doesn’t support either of the USB-A fast charging specs, it will slow charge at either 500mA or 900mA which is about the same you can expect from directly connecting it to most PCs.

Mode Voltage Max Current Connector
USB PD Variable up to 20V 5A USB-C
USB Type-C 3A 5V 3.0A USB-C
USB Type-C 1.5A 5V 1.5A USB-C
QC 4.0 (USB-PD Compatible) Variable up to 20V 4.6A USB-C
QC 3.0 Variable up to 20V 4.6A USB-A/USB-C
QC 2.0 5V, 9V, 12V, 20V 2A USB-A
USB BC 1.2 5V 1.5A USB-A
USB 3.1 5V 900mA USB-A
USB 2.0 5V 500mA USB-A

Many of the portable batteries on the market have both USB-C and multiple USB-A ports. Some of them have USB-A ports which can deliver the same voltage, while others feature one fast (2.4A) and one slow (1A).

So you will want to make sure you plug the device into the battery port which can charge it at the fastest rate if you want to top off the device as quickly as possible.

USB Power Delivery

USB Power Delivery (USB PD) is a relatively new fast charge standard which was introduced by the USB Implementers Forum, the creators of the USB standard.

It is an industry-standard open specification that provides high-speed charging with variable voltage up to 20V using intelligent device negotiation up to 5A at 100W.

It scales all the way up from smartphones to notebook computers provided they use a USB-C connector and a USB-C power controller on the client and host.

Batteries and wall chargers which employ USB PD have the ability to charge devices up to 100W output using a USB-C connector — however, most output at 30W because that is on the upper range of what most smartphones and tablets can handle, whereas laptops require adapters and batteries that can output at a higher wattage.

Apple introduced USB PD charging with iOS devices with the launch of the 2015 iPad Pro 12.9″ and with OS X laptops in the MacBook Pro as of 2016. The iPhone 8, the iPhone X and XS/Max can rapid charge with USB PD using any USB PD charging accessory — you don’t have to use Apple’s OEM USB-C 29W or its 61W power adapters — but it requires that you use Apple’s OEM MKQ42AM/A (1m ) or MD818ZM/A (2m) USB-C to Lightning cables which unfortunately are a tad expensive at around $19-$35 from various online retailers.

Personally, I buy mine from Amazon but your mileage may vary.

apple-usbc-to-lightning.jpgapple-usbc-to-lightning.jpg

Apple OEM USB-C to Lightning Cable. The only fast charge cable for iPhones that currently works.

There are cheaper 3rd-party USB-C to Lightning cables, but none of the ones we have tested on the market will charge current generation iOS devices at full speed — they can’t do better than 2.4A because Apple uses a special integrated circuit in their cables for power negotiation.

We are expecting to see 3rd-party MFI-certified USB-C to Lightning cables — hopefully less expensive than Apple’s OEM cable — by the end of Q4 of 2018, so watch this space.

We would also like to mention Belkin because although they do not have a USB PD battery solution or MFI-certified USB-C cables yet, they do have some excellent USB PD wall charging and 12V car charger solutions which are much more cost-competitive than the OEM Apple 29W USB-C charger.

Qualcomm Quick Charge

Qualcomm, whose Snapdragon SoCs are used in a number of popular smartphones and tablets, has its own fast-charging standard, Quick Charge, which has been through multiple iterations.

The current implementation is Quick Charge 4.0 which is backward-compatible with older Quick Charge accessories and devices. Unlike USB PD, Quick Charge 2.0 and 3.0 can be delivered using the USB-A connector. Quick Charge 4.0 is exclusive to USB-C.

Quick Charge 4.0 is only present in phones which use the Qualcomm Snapdragon 835/845 which can be found in the US version of the Samsung Galaxy S9 and Galaxy Note 9, OnePlus 6, HTC U11, LG V30, Moto Z2 Force, the Google Pixel 2 XL and upcoming Pixel 3 XL.

The Xiaomi Mi 6, Xiaomi Mix 2, ZTE Nubia Z17, and the Sony Xperia XZ Premium also use QC 4.0, but they aren’t sold in the US market currently. Huawei’s phones utilize their own Kirin 970/980 chips which use their own Supercharge standard but they are backward compatible with the 18W USB PD standard.

Like USB PD, QC 3.0 and QC 4.0 are variable voltage technologies and will intelligently ramp up your device for optimal charging speeds and safety. However, Quick Charge 3.0 and 4.0 differ from USB PD in that it has some additional features for thermal management and voltage stepping with the Snapdragon 820/821/835/845 in order to optimize for reduced heat footprint while charging.

It also uses a different variable voltage selection and negotiation protocol than USB PD which Qualcomm advertises as better/safer for its own SoCs.

And for devices which use Qualcomm’s current chipsets, Quick Charge 4.0 is about 25 percent faster than Quick Charge 3.0. The company advertises five hours of usage time on the device for five minutes of charge time.

However, while it is present in (some of ) the wall chargers that ship with the devices themselves, and a few 3rd-party solutions, Quick Charge 4 is not in any battery products yet. The reason for this is that it is not just competing with USB Power Delivery, is also compatible with USB Power Delivery.

Qualcomm’s technology and ICs have to be licensed at considerable additional expense to the OEMs, whereas USB PD is an open standard.

If you compound this with the fact that Google itself is recommending OEMs conform to USB-PD over Quick Charge for Android-based products, it sounds like USB PD is the way to go, right?

Well, sort of. If you have a Quick Charge 3.0 device, definitely get a Quick Charge 3.0 battery. But if you have a Quick Charge 4.0 device or an iOS device, get at USB PD battery, for now.

Which Battery?

Now that you understand the fundamental charging technologies, which battery to buy?

Vendor Model Tech Capacity
/mAh
Port 1 Port 2 Port 3 Port 4 MSRP
RavPower RP-PB058 USB PD 26800 USB-A USB-A USB-C (30W) USB-Micro-B (Input) $79.99
Anker PowerCore+ 26800 PD* USB PD 26800 USB-A USB-A USB-C (30W) * $119.99
RavPower RP-PB043 QC 3.0 20100 USB-A USB-A (QC 3.0) USB-C (18W) USB-Micro-B (Input) $49.99
RavPower RP-PB059 USB PD 20100 USB-A USB-A USB-C (30W) USB-Micro-B (Input) $69.99
Anker PowerCore Speed 20000 PD* USB PD 20100 USB-A USB-C (30W) * * $99.00
Anker PowerCore II 20000 QC 3.0 20000 USB-A (18W) USB-A (18W) * * $49.99
Mophie Powerstation USB-C XXL USB PD 19500 USB-A USB-C (30W) * * $149.95
Mophie Powerstation Plus XL USB PD 12000 USB-A (15W) USB-C (18W) * * $99

* Two Anker models — PowerCore+ 26800 PD and PowerCore Speed 20000 PD — are the only two models to include a wall charger.

We’ve tested a bunch of these and we’ve essentially narrowed it down to two: The RAVPower RP-PB058 for USB PD (newest iPhones and newest Androids) and the Anker PowerCore+ 26800 for Quick Charge 3.0 (Previous generation Androids). Both are 26800mAh batteries with huge charge capacity.

Anker’s product is more expensive but it comes with a USB-C QC 3.0 wall charger that can be used with the battery or direct charge a QC 3.0 compatible device, whereas the RAVPower we have seen on the street as low as $60 with wide market availability and with Amazon Prime promotions, so be sure to shop around because that is a great value at that price.

Anker also has a USB PD version of the PowerCore+ 26800 bundle but it is not as easy to find. We suspect the company is working on a new product revision compatible with USB PD and QC 4.0 and it will be out after the holidays — but if you see the current model on sale, jump on it. We particularly like the metal case design and the large illuminated power stud button that is easy to feel even in the dark.

ZMI 20000 USB PD


ZDNet

Both of these companies sell equivalent USB PD and QC 3.0 products including compatible wall chargers (see Anker and RavPower). As with Apple’s own OEM accessories, it isn’t necessary to match brands when pairing a wall charger with a USB PD or QC 3.0 battery.

However, because of licensing, the QC 3.0 ones appear to be priced more expensively — so unless you have a QC 3.0 compatible device, we suggest you stay with USB PD charging accessories for now.

A product that we did not mention in earlier drafts of this article is the ZMI 20000 mAh USB PD Backup Battery which along with its USB PD wall charger is currently on promotion at Amazon.

If you buy both of these products together, Amazon will apply a promotional discount, which makes the combined price $89.90 which is less than what Anker and RavPower offer their equivalent battery/charger bundles for.

This particular product has the distinction of having both USB PD and QC 3.0 capabilities, has a 45W USB PD output for charging everything up to laptops, and can also act as a daisy-chained USB 2.0 hub, so it is a particularly good buy. ZMI makes OEM products for Xiaomi, a huge Chinese smartphone manufacturer which like Huawei, has yet to find US carrier distribution yet.

Two other products we would like to mention are the Mophie Powerstation USB-C XXL and the Mophie Powerstation AC.

The USB-C XXL is a very nice looking battery as it integrates a fabric wrap over the polycarbonate casing so it’s pleasant to the touch — and it fully supports USB PD at 30W.

Its big brother is the Powerstation AC, which in addition to a USB-C PD and USB-A port, also has a 110VAC/100W port to supply power to virtually anything that uses standard 110V plugs, including legacy laptops and other electronic devices.

Twitter rolls out the ability for creators to host Super Follows-only Spaces – TechCrunch

Published

on

Twitter has announced that it’s rolling out Super Follows-only Spaces. Creators who offer Super Follows subscriptions can now host Spaces exclusively for their subscribers. The social media giant says this new option will give creators a way to “offer an extra layer of conversation to their biggest supporters.”

Subscribers globally on iOS and Android will be able to join and request to speak in Super Follows-only Spaces, whereas subscribers on Twitter’s web platform can join and listen, but won’t have the option to request to speak. Creators can start a Super Follows-only Space by selecting the “Only Super Followers can join” button when starting a new Space. Users who aren’t Super Following a creator will still see the Space, but won’t be able to access it unless they subscribe.  

It’s worth noting that the new Super Follow-only option for Spaces isn’t the only way for creators to hold exclusive Spaces. For example, Twitter launched its Ticketed Spaces feature last year to allow creators to set a price for users to listen in on a Space. Creators can set their ticket price anywhere between $1 and $999 and can also limit how many tickets are sold.

Super Follows, which was first revealed in February 2021, allows users to subscribe to accounts they like for a monthly subscription fee in exchange for exclusive content. Super Follows is currently in testing with select creators in the United States on iOS. Eligible accounts can set the price for Super Follow subscriptions, with the option of charging $2.99, $4.99 or $9.99 per month.

The launch of Super Follows-only Spaces adds another layer of exclusivity to Super Follows subscriptions. Twitter says it plans to launch more Super Follows features to allow creators to grow their audiences and get closer to their most engaged followers.

Twitter says its research shows that hosting consistent Spaces leads to more follower growth and also gives creators more ways to engage with their followers. The company found that consistently hosting Spaces, around two times per week, leads to a 17% follower growth over a quarter. In addition, the company says creators who host consistent Spaces for a month see a 6-7% growth in followers, and creators who do so for two months see a 10% growth in followers.

TikTok launches its first creator crediting tool to help video creators cite their inspiration – TechCrunch

Published

on

After years of stolen memes and uncredited dance trends, TikTok today is introducing a new feature that it says will be the first iteration of its creator crediting tools that allow creators to directly tag and credit others using a new button during the publishing process. This button lets creators credit all sorts of inspiration for their content, including dances, jokes, viral sounds, and more — and will help TikTok viewers discover the original creators behind the latest trend by tapping on the credit from the video’s caption.

Larger creators lifting ideas from smaller ones is an issue that’s not limited to TikTok. But as one of the largest social apps on the market, particularly among a younger Gen Z to Millennial demographic, how it approaches the issue of creator recognition matters.

To that end, TikTok says it’s now rolling out a new feature that will allow users to add a credit as part of the publishing process on the app.

Image Credits: TikTok

To access the feature, users will tap on a new “video” icon on the posting page after creating or editing their own video. Once on the video page, users will be able to select a video they have liked, favorited, posted, or that had used the same sound.

After this video is selected, the video tag will be added as a mention in the caption.

Those whose videos were tagged by another creator will then be alerted to this via an alert in their TikTok app Inbox.

The feature’s launch follows years of controversy over creator credits and attribution on TikTok.

In particular, TikTok had struggled with some of its top stars sourcing new choreography to perform in their dance videos from creators on other, smaller platforms — like the rival short-form video app Dubsmash, later acquired by Reddit. Many of these unknown creators had helped kick off TikTok’s biggest dance trends in years past, like the Renegade, Backpack Kid, or Shiggy. And many were creators of color, who saw their dances go viral after more famous TikTokers would perform their moves without tagging them as the inspiration. This issue came to a head when The New York Times in 2020 reported on the original creator of the Renegade, then a 14-year-old Atlanta teen, Jalaiah Harmon, who hadn’t received credit for her work after TikTok’s largest creator, Charli D’Amelio, performed her dance for her millions of fans, helping her to further grow her already outsized celebrity status.

The following year, a similar controversy made headlines after TikTok star Addison Rae went on “The Tonight Show” where she taught host Jimmy Fallon a number of popular TikTok dances. Meanwhile, the dances’ original creators, many of whom are Black, remained uncredited in the segment. Later, a number of Black creators went on strike as part of a viral campaign to call attention to the issue of creator credits by refusing to choreograph a dance to Megan Thee Stallion’s latest single.

D’Amelio and some other creators have since begun to handwrite dance credits in their video descriptions, often using the shorthand “dc” for dance credit followed by a tag pointing to the username of the creator. A famous Hollywood choreographer, JaQuel Knight, who made history as the first to copyright his work, has also begun helping other dancers on TikTok get credit for their work too, Vice reported in December.

But dances aren’t the only things being stolen on TikTok. Creators have fielded accusations of stealing everything from cheerleading routines to comedy bits to challenge ideas to music or sounds and much more.

 

A TikTok spokesperson acknowledged the problem with credits on the platform, noting that the culture of credit was “critical” for the community and for  TikTok’s future. “Equitable creator amplification is important for creators, especially the BIPOC creator community,” they added.

Image Credits: TikTok

In an announcement, Director of the Creator Community at TikTok, Kudzi Chikumbu introduced the feature and highlighted other efforts the company has made to help better highlight original creator work on its platform.

Chikumbu pointed to TikTok’s Originators series, launched last October, which showcases trend originators through the app’s Discover List feature. TikTok also recently debuted a TikTok Originators monthly social series highlighting Originators on the platform. In addition, the TikTok Creator Portal includes a “Crediting Creators” section that highlights the importance of attributing trend originators for their work. Here, the company lays out best practices for crediting originators and explains how to find the originators if you aren’t sure who had started a trend.

The use of the new crediting tag could help make it easier for creators to cite their inspiration. However, it still relies on user adoption to work. If a creator wants to lift ideas without credit, they could simply not use the feature.

“It’s important to see a culture of credit take shape across the digital landscape and to support underrepresented creators in being properly credited and celebrated for their work,” said Chikumbu. “We’re eager to see how these new creator crediting tools inspire more creativity and encourage trend attribution across the global TikTok community.”

TikTok’s new ad product gives creators a chance to partner with marketers on branded content – TechCrunch

Published

on

TikTok announced today that it’s launching a new ad product called “Branded Mission” that will allow creators to connect with brands and possibly receive rewards for videos. With the new ad product, advertisers can crowdsource content from creators and turn top-performing videos into ads. Advertisers can launch branded campaigns and encourage creators to take part in them. Brands can develop a brief and release it to the creator community encouraging them to participate in Branded Missions.

Creators can then decide what Branded Missions they want to participate in. All creators who are at least 18 years old and have at least 1,000 followers are eligible to participate in a Branded Mission. TikTok says eligible creators whose videos are selected by brands will “benefit from a cash payment and boosted traffic.” On each Branded Mission page, creators will be able to view how much money they have the potential to earn if their video is selected.

Branded Mission is now in beta testing and available to brands in more than a dozen markets. TikTok says the new ad product will be available in additional markets later this year.

The company says this new form of two-way engagement between brands and creators allows the TikTok community to have a creative hand in the ads that are part of a brand campaign. TikTok notes that it’s always looking for creative ways to support creators and help brands reach users on its platforms with relevant content.

“Creators are at the center of creativity, culture and entertainment on TikTok,” the company said in a blog post. “With Branded Mission, we’re excited to bring even more creators into the branded content ecosystem and explore ways to reward emerging and established creators.”

TikTok and brands already leverage creators for ads on the platform, but the new Branded Mission ad product will give creators, especially newer ones, a new way to partner with brands and grow their audiences.

Today’s announcement comes as TikTok recently introduced a new way to lure advertisers to its platform by giving them the ability to showcase their brands’ content next to the best videos on TikTok. TikTok launched TikTok Pulse, which is a new contextual advertising solution that ensures brands’ ads are placed next to the top 4% of all videos on TikTok. Notably, the solution is also the first ad product that involves a revenue share with creators. Creators and publishers with at least 100,000 followers on TikTok will be eligible for the revenue share program during the initial stage of the TikTok Pulse program.

TikTok has also been looking for ways to help brands better reach users on its platform. Last month, the company launched a new Creative Agency Partnerships (CAP) University program that is designed to help creative agencies become “TikTok experts.” The five-week program teaches enrollees what they need to know about getting started on TikTok and how to use the platform to up their marketing game.
