At the 2017 Snapdragon Technology Summit, Qualcomm unveiled Quick Charge 4+ wall and car chargers. The chargers though made by a third-party company are the first to be certified by Qualcomm. Below is an unboxing and quick review of the wall charger.

The charger comes in a blue and white box and is made by Ever Win (Dongguan Yi. Electronics) International Corp. The charger itself has a matte black flame retardant shell with an American plug. There is a USB-C output port on top and a Quick Charge logo below it.

On one side of the charger, the various charging outputs are listed. There is 5V/3A, 9V/3A, 11V/2.4A, and 12V/2.25. However, a test using a ChargerLAB POWER-Z USB voltmeter revealed that the charger also supports Quick Charge 2.0, Quick Charge 3.0, and USB Power Delivery 3.0.

Below is a table of various phones, supported charging technology and the amount of watts drawn when using the QC4+ charger.

The Huawei Mate 9 is able to charge at up to 17.69W. It is followed closely by the iPhone 8 Plus which charges at 9.09V/1.90A (16.27W), and the Meizu PRO5 at 9.10A/1.78A (16.20W). All the above mentioned devices support USB Power Delivery. However, the New MacBook Pro didn’t charge fast even though it also supports USB PD.

The charger also doesn’t supports Apple’s 2.4A fast charging protocol, so using this charger with your iPad Air 2 or iPhone 7 won’t give you the fastest possible charging speed.

For Quick Charge 3.0, the charger was able to charge the Sony Xperia XZ premium and the Xiaomi Mi 5.

Its interesting to know that the charger supports multiple charging protocols even though not all devices are able to take advantage of it.

LeEco isn’t holding back when it comes to drumming up hype for their upcoming phone, the LeEco Pro 3. The company released a poster yesterday teasing the small capacity batteries in the new iPhones. Today, they’ve released another image taking aim at the lack of fast charging in Apple’s new release.

The LeEco Le Max 2 supports Qualcomm’s Quick Charge 2.0 and uses a 24W high power charger for it’s 3100mAh battery. Both versions of the Le Pro 3 will feature batteries with higher capacities than that of the Le Max 2 (4070mAh and 5000mAh). So it’s a no-brainer that they should support fast charge (most likely Quick Charge 3.0) as well.

The  LeEco Le Pro 3 will launch on the 21st of September and is already shaping up to be one of the best devices of the year. Users will be able to choose either a 6GB+64GB version with a 16MP rear camera and an 8MP front facing camera or the industry’s first 8GB RAM phone which has 256GB of storage, dual 13 megapixel cameras on the rear, and a 16MP camera in front.  Both units will sport Qualcomm’s newest SD 821 chip and will be priced between $314 and $449.

If you feel you don’t need all those specs, the LeEco Le Max 2 is one of the best value for money flagships right now. It has a 2K display, uses a snapdragon 820 chip, has a 21MP rear camera with OIS and PDAF, NFC, and a fingerprint scanner. The icing on the cake is that it sells for less than $270 for the 4GB RAM version with 32GB of built-in storage.

A couple of the big names into mobile device manufacturing have their own fast charge technology that is specially designed for their phones. Although, they might work with other brands, they are usually more efficient with their own products. An example is Motorola’s TurboPower fast charge technology (gives 8 hours of battery life in 15 minutes of charging) which will also work with Quick Charge 2.0 compatible devices.

Huawei seems to have come up with their own fast charge technology called Supercharge and they have applied for a trademark for it in the European Union. A prototype of the Supercharge technology was demoed last year at a battery symposium in Japan when a 3000 mAh Li-ion battery was charged to nearly 50% in 5 minutes and a 600 mAh battery charged to 68% in 2 minutes. That is really really fast if you ask me. While there were opinions raised about it damaging the battery, we want to believe the batteries were specially made to withstand that voltage and current, and even if there is a risk, the issue must have been solved already for them to want to trademark the name. Do not forget that applying for a trademark means that you intend to use something commercially.

People have speculated that the charging technology might start showing up in future Huawei devices, with the Huawei Mate 9 being the first device to feature the charging technology. When Supercharge does launch,it will go up against Qualcomm’s Quick Charge 3.0, OnePlus’s Dash Charge (or OPPO’s VOOC) and other fast charging technologies.

ZUK announced its first smartphone, ZUK Z1 last month with flagship features such as a 5.5-inch 1080p FHD display and Snapdragon 801 chip. The highlight of the device was its support for latest USB 3.0 standard on the USB type-C port. This made ZUK Z1 the first smartphone with such configuration. Since the phone came with a massive 4100mAh battery, it was necessary for the device to feature a tech like fast charge. Also, we know all Qualcomm 800 series processors supported Quick Charge 2.0, and hence we expected even the ZUK Z1 to come with this tech. But according to a charging analysis of the international version of the ZUK Z1 flagship by the smart charger manufacturer Tronsmart, the device does not support QC 2.0. This could be due to hardware or software limitations.

Before we move on to see the analysis by Tronsmart, lets take a look at the specifications supported by QC 2.0.

Now coming to the actual analysis done by Tronsmart, they tested the international version of the ZUK Z1. This version comes with CyanogenOS and supports charging at 5V 2A. On the other hand, the Chinese variant with ZUI comes with support for 5.3V 2.5A.

Using the original 5V/2A adapter provided in the packaging, the ZUK Z1 charged up to 15% in about 20 minutes. According to their test, the phone was charging at full 2A limit when the screen was off. The total charging time from 0% to 100% of its 4100mAh battery took about 2.5 hours, which is pretty impressive.

However, we had to see whether the phone supported QC 2.0, which can take more than 2A of current. To test this, the guys over at Tronsmart swapped the original charger with their own QC 2.0 supported fast charger at 2.5A. However, even with this charger, the result was more or less the same.

As a result, it looks like the international version of the ZUK Z1 limits current to 2A, which means it does not support fast charging at QC 2.0 standard. On the other hand, the Chinese variant with EUI will charge at a slightly faster rate since its supports charging at 2.5A.

But to be honest, even without QC 2.0, ZUK Z1 manages to impresses us by charging up to 100% within 2.5 hours. So, I am sure, many won’t mind the lack of Quick Charge 2.0 support on the device.

But we would like to know if you are disappointed to hear this news? Or are you fine with the charging time of 2.5 hours?

Let us know in the comments section below.
