Does Kwik Charger Actually Allow Me To Charge My iPhone 2X Faster?

This is the most important question you should be concerned about -- and the answer is a resounding YES for charging your iPhone 6, 6S, 6 Plus, or 6S Plus.

To put it in simple terms, the newer models of iPhones come with a built-in but unadvertised capability to request a higher charge from the charger.  iPhones 5S and older can only request the standard 1A, 5 Watts from the charger.

To illustrate this concept in action, we've put together a quick video showing an iPhone 6S being charged with the charger you get when you buy your iPhone, and then afterwards with one of our Kwik Chargers.  We stand 100% behind our claim that our product WORKS.

OK I believe you. But won't charging it faster damage the battery?

This is a very fair question, and we are going to try to explain it both in very plain terms and also later on with a more technical analysis.  We know that most of you are not electrical engineers, so the simple answer is: NO.  

A simple way to think about the relationship between any charger and the device it's charging is like this: The phone will communicate with the charger and tell it how much power/energy to give it.  The charger then gives it exactly how much it needs.  Since Apple designed the iPhone, they know exactly how much power is safe to request from the charger.  This is one of the same reasons why you can use your charger in foreign countries where their electricity sockets and voltage are different.

The reason why the regular charger that comes with your iPhone cannot charge it as fast as a Kwik Charger, is that the maximum capacity on it is 5 Watts & 1 Amp.  The Kwik Charger can charge at 12 Watts & 2.1 Amps.  In short, the iPhone can request for more power from the regular charger, but the regular charger simply doesn't have the capability to provide the iPhone with any more.  It's already giving your phone all it's got!

The important thing to remember at the end of the day is that the Kwik Charger WORKS and it charges your phone 2X faster WITHOUT any danger to your battery or battery life.

Can you explain in more detail why fast charging won't damage my battery?

Sure we'd love to!  Just a FYI the rest of this article may be a bit technical for anyone who is not into electronics or how they work...

Ivan Cowie, the chief engineer at MaxVision and author of an EE Times series, “All About Batteries,” notes that the iPhones have actually been charging at a lower speed than they are designed to charge at. Simply increasing the current from .5 amps (USB charging cable) or 1 amp (the bundled iPhone charger) to 2.1 amps (the Kwik Charger) boosts the charging speed.

What effect does this have on your device? Most people incorrectly conclude in a blanket statement that more amperage equals more heat, and more heat equals more wear and tear on the battery. For this reason, it’s common for people to conclude that using our Kwik Charger is a bad idea. But in this case, knowing just a bit more about how batteries work may ease your mind.

Isidor Buchmann, founder and CEO of Cadex Electronics and author of “Batteries in a Portable World,” explains a key measurement that determines how much charge a phone can safely receive is the C-rate, or the rate at which a battery charges or discharges. To determine a C-rate, simply take the ratio between the charging rate and the capacity of the battery as measured in mAh or milliampere-hours. For an iPhone 6 that is being charged with the Kwik Charger, the C-rate is 2100mA/1810mAh or 1.16C. For an iPhone 6 Plus, the C-rate is 2100mA/2915mAh or 0.72C.

Most portable batteries are rated at 1C.  This puts the C-rate that we calculated for the iPhone 6 and 6 Plus in the safety zone.  ”A battery manufacturer would recommend a rate below 1C,” Buchmann said. "But a rate that is just barely above 1C is nothing to be concerned about", he added.

Another thing to keep in mind is how charging your phone faster actually works. This is how George Paparrizos, a director of product management who works on Qualcomm’s Quick Charge 2 technology explained it:  "A bit of code on your device, often located in a chip known as the Power Management IC, communicates with the charger you are using and requests that it send power at a higher voltage. The Power Management IC, also known as the PMIC, receives this voltage and converts it into a voltage and current that is suitable for a particular battery."

This step exists to protect the battery of an iOS device because Apple would still determine the voltage and current provided to its batteries, regardless of your choice of charger.  It's also worth noting that all newer iPhones ALL USE the same exact PMIC's from George's company, Qualcomm!
