Google warns: USB Type-C are not all the same

Cheap cables can lead to problems, here’s what to check before you buy


We are all happy with the USB type-C, the new front door that is more comfortable, powerful and versatile than the previous, but there is a problem: not all cables are the same and even the loaders could create some problem. To say it, Benson Leung, Google Engineer, entered the market of the new USB with the latest Nexus 5x and Nexus 6p.


The USB-C is designed to work up to 3 amperes but many cables on the market do not arrive at that quota or do not identify the device properly to recharge and, in short, do not do their job. Better then check that the purchased cable is certified 3a.


The flaws are not finished, because on the other side of the cable is the transformer: the models on the market can be from 1, 5a or 2, 1a, which means that you have to use a cable that can reduce the power and avoid problems. The other considerations of Leung can be read here, but the substance is only one: do not buy cheap cables or they will be trouble.

iphone 8: All models with Lightning connector and USB-C fast Charging

It is just two days since the Wall Street Journal has reported that Apple will put on the iphone 8 on USB-C instead of lightning. We were skeptical and now there is the resolution that Apple is likely to tread with the iphone 8 as well as the iphone 7S and iphone 7S Plus.


All 2017 iphone models with Lightning and USB-C fast Charging


There is a lot of evidence that Apple will be putting on three new iphone models this year. In addition to the new iphone 8 we reckon with the iphone 7S as well as iphone 7S Plus. In part, the models are based on the same technologies and are fundamentally different from each other.


One feature that will be identical is the Lightning port with USB fast charging technology. After the WSJ put a USB-C port on the iphone 8 into play, the usually well-informed analyst Ming Chi Kuo is now speaking. This one should give an open ear.


New 2H17 models may all support fast charging. We believe all three new iphones launching in 2H17 will support fast charging by the adoption of type-C power delivery technology (while still retaining the Lightning port). A key technical challenge lies with ensuring product safety and stable data transmission during a fast charge. In order to achieve that goal, we think Apple will adopt TI’s power management and Cypress’s power delivery chip solutions for the new iphone models. We note the OLED version may have a faster charging speed thanks to a 2-cell L shaped battery pack design.


According to Kuo, Apple will be installing a lightning connection on all new 2017 iphone models. At the same time, Apple will rely on new internal components that enable the benefits of USB-C fast charging. The physical plug will therefore not change. Among other things, Apple will use the appropriate chips for power management at Texas Instruments and Cypress.


According to the analyst, there are two reasons why Apple will remain loyal to the Lightning connection. On the one, there would be the large offer of MFI accessories and the associated royalties and the form factor of lightning. Lightning is less than USB-C in its construction.


In general, Apple is expected to present the iphone 8 in the autumn of this year. Among other things, Apple is to put this device on a 5.8 inch display, an improved camera system, a more powerful processor, and wireless charging.

What’s that USB type-c on the MacBook?


What’s that USB type-c on the MacBook?


On March 10, Apple published a new MacBook at the Grass Art Center in San Francisco, USA, and its lightness has left a deep impression on countless consumers. Once again, the pursuit of the acme of Apple on the various interfaces on the MacBook waved the butcher’s knife, in the case of cutting off all the original interface, we introduced a kind of lightning interface as thin and small new USB interface: USB type-c.


So the question is, where is the USB type-c, and why does Apple choose USB instead of pushing Thunderbolt for years?

On March 10, Apple published a new MacBook at the Grass Art Center in San Francisco, USA, and its lightness has left a deep impression on countless consumers. Once again, the pursuit of the acme of Apple on the various interfaces on the MacBook waved the butcher’s knife, in the case of cutting off all the original interface, we introduced a kind of lightning interface as thin and small new USB interface: USB type-c.


So the question is, where is the USB type-c, and why does Apple choose USB instead of pushing Thunderbolt for years?


What is USB type-c?


USB type-c was not long ago and was finalized in the USB 3.1 standard published in August 2014. It is a specification of a new USB cable and connector that defines a whole new set of USB physical specifications, including connectors, ports, containers, and cables.


Brand new interface size and slightly cool name, very easy to let the first time to hear this noun consumers think this is a brand new USB standard, but actually not. USB type-c is only part of the USB 3.1 standard, not a new standard. Also, as with common USB 2.0, USB 3.1 standards still have type-a (common to computer hosts) and Micro-b (common to Android handsets), and type-c is not the only option for consumers to enjoy USB 3.1 high-speed data transmission.


So why does a USB organization need to introduce a new physical interface specification?


With more and more new equipment for lightweight, miniaturization of the pursuit of traditional USB interface “large” size has been difficult to meet the needs of equipment manufacturers and consumers. At the same time, the traditional USB interface needs to be repeatedly unplugged, looking for the “correct” direction of the problem has been widely criticized by consumers, the user desperately needs a similar lighting interface as the opposite side can be plugged into the interface, especially in the mobile phone, such as a large number of connected to the data line equipment The experience of inserting a wrong interface one or two times a day is never good.


Based on these problems, the USB standard makers have introduced the TYPE-C physical interface specification, introducing several major features in the specification:


Thin: Unlike traditional type-a interfaces in life, the new type-c interface is extremely thin in size, and is only 3×2.5mm is more suitable for use in increasingly miniaturized computing devices.
No directionality: Similar to the Apple Lightning Interface, the Type-c interface has no directional requirements, and positive and negative inserts can be paired, which improves the usability of the USB interface.


Thunderbolt interface


Back to the Thunderbolt interface of Apple. Thunderbolt is a technology that Apple has developed in depth collaboration with Intel, combining traditional PCIe data transmission technologies with DisplayPort display technologies. The Thunderbolt interface was applied by Apple in 2011 to the MacBook Pro pen.


Its main advantages are: The bandwidth is large, the transmission speed is fast. After the revamped new Thunderbolt 2 interface, can realize the bidirectional 20Gbps theory transmission speed, is far higher than the USB 3.1 10Gbps theory transmission speed.


Prior to this announcement, Thunderbolt has been considered an interface specification that Apple and Intel value and will vigorously promote. So why would Apple eventually choose to use a USB Type-3 in the new MacBook?


By comparing the information about the two interface specifications, we are careful to guess the following reasons:


Interface size: The Thunderbolt interface does not have any advantage over the size of the USB Type-c’s slim (5mm).
Cost control: Under Intel’s strong control, the price of Thunderbolt interface chip has been high for many years, which brings great pressure on manufacturing cost and retail price of various related equipments, while the price of USB TYPE-C chip is relatively low, which can greatly explain the cost of Apple controlling hardware.
Power supply: The Thunderbolt interface provides only the maximum 10W of power output, while the USB 3.1 Type-c interface provides up to 100W of power output, that is, the Typc-c interface can be used directly for another laptop or smartphone without any transformers.
Amplification Capacity: USB 3.1 has a wide range of extended space, including 4K image DisplayPort output can also be easily implemented via USB 3.1.
In fact, Apple is not the only device manufacturer to choose USB type-c, not even the first one. The Nokia N1 tablet computer, which was just published in China this January, also chose USB Type-c as its only data interface. Based on its excellent data transmission performance, fiber-thin interface size and low price, coupled with Apple equipment and other star products, USB Type-c should be able to quickly spread over the next few years, in the new era of action to shine.


USB interface type other than USB type-c


The Chinese full name of the USB interface is a universal serial bus, a standard set by a non-profit organization of 7 technology companies, including Microsoft, Intel and IBM, in 1994. The initial purpose is to illustrate that external devices are better connected to the computer and exchanged for data. After more than 20 years of development, the USB standard has gone from 1. x, 2.0, 3.0 to 3.1 versions of the development, data transmission rate has made considerable progress.


In addition to the eye-catching type-c, USB actually has a very rich range of other types of connectors (including a lot of USB-certified but standardized connectors), the above figure shows the common 3 kinds of 5 kinds of interfaces: standard interface, Mini interface and Micro interface.


TYPE-A: Standard Version USB interface
USB C HUB is the most common type of USB interface in our daily life, which is usually connected to the computer on the end of the online type-a. But it has some more notable problems: first of all, it has a certain directional requirements, the user must from a certain direction to plug the connector (the mouth) into the interface (the mother), but because the two sides of the USB Port profile is very close, this insert process often error; In addition, the size of the type-a is really too big, TYPE-A interfaces are almost impossible to pursue on portable devices. Because of this, Micro and Mini interfaces came into being and were developed in portable devices.


The interesting thing is that, traditionally, the USB line works in a model where the endpoint is a type-a type (for connecting to a computer), and the other endpoint is the Type-b type (used to connect the device), so there is little to see at both ends of the type-a cable; USB type-c is a type of interface that can be applied both to the master device (host) and from the device.


Micro-b: USB Standard for mobile devices
It is worth mentioning that the current majority of Android phones are Micro USB interface (that is, USB Micro-b), the interface in 2007 by the Nokia, Samsung, Motorola and other companies, including the Open Action Terminal Platform organization launched and gradually spread, So far it has been widely used in various mobile portable devices.

IPhone 8, Caricatore da 10 W with USB Type-C

New rumors arrive on the IPhone 8, the smartphone of Apple bitten on which is speculating a lot because of the conceptual revolution that it should offer. According to KGI Securities Ming-Chi Kuo, usually reliable source, the IPhone 8 should have a charger compatible with the standard “USB Type-C Power delivery”. This element should be the clue that Apple’s next Melafonino may have quick recharge support. Actually, today’s iPhone charging times are not short ceros, especially with the competition offering fast charging solutions on all new models.


Although, however, the charger will be compatible with the standard “USB type-C Power delivery”, the charging port will always be of the Lightning type. Next to these rumors arrive those of Barclays always on the same subject. According to the analyst, the charger will have a maximum power of 10w. This is a very high value, twice the power of the current IPhone chargers and just below the power of those for the IPad.


It seems, therefore, quite clear that the next IPhone will have a quick recharge support that can shorten the recharge time considerably. According to the past rumors, the IPhone 8 should also have wireless charging.


In any case, it is always of indiscretions that as such must be taken. You will know more over the next few weeks as you approach the presentation of the IPhone 8 scheduled at the beginning of autumn.


What you need to know about USB type C

USB type C


Here are the new generation USB connectors called “USB type C”, so announced the USB-IF (USB implementers Forum).


We all know the USB connector and as it has been maintained in time for 3 generations, despite its size and only be able to be connected in a single direction. And while the manufacturers have already created the Mini-USB and the Micro-USB is with the “type C” when you expect a change that will assume a before and after in the USB connectors.


Apart from many other novelties I think the best thing is to enjoy the “type C” in all types of devices both because of its conception itself and its size that is very similar to the micro-USB that we met in the USB 2.0 (micro-B). In addition we can not fail to mention that this new connector will replace all the USB connectors in a small and reversible that will be connected in two senses.


This little giant will save us the multitude of cables that we use when we have several devices, because being simply a connector can be used in alternative modes, being used as digital video output and audio (HDMI), DisplayPort output, analog video output (VGA), etc.


In fact the Apple has put on sale a hub along with its new Macbook with this connector and in order to eliminate the mess generated in recent years, is what has unleashed the rumors and benefits of USB type C.


Why did you lift so much dust this “C” type and use it on the Macbook? The answer is pretty straightforward. So far our smartphones, phablets, cameras etc have a USB 2.0 port whose maximum power is 2.5 W, 0.5 A to 5 volts, but regret this port is only for small-capacity batteries, it would be impossible to load devices as a “laptop”. However the new Macbook, among other models of Apple, is loaded with a USB port type C which according to its specifications establishes a transfer limit of 100w. It is also reversible so not only you can load the laptop but you could also load your Smartphone by connecting to your laptop, and you will also do at that rate of 100w much higher than the current 2.5 W.


But eye should not confuse the type C with the 3.1. USB 3.1 is a standard announced at the beginning of 2013 and developed by the USB-IF with the intention of updating the standard USB 3.0 at a speed of 10Gbits/s, while USB type. C is a type of connector.


It is clear that we will not take long to start to see this new connector circulate in the devices but we can not ignore that the Micro-USB is already the mobile standard for many Governments and organizations which will be a stumbling block.
