All iPhone 6 models come with a regular 5W 1A wall charger, but it turns out that you can charge your iPhone 6 faster than a 5W charger, thanks to Apple’s support for 10W 2.1A iPad chargers.
In the past, you could technically charge your iPhone 5s or iPhone 5 using larger iPad chargers, under the misconception that more output from the larger charger would lead to faster charging. However, the iPhone is designed to draw only enough water to sufficiently charge it; that means a larger iPad charger isn’t really worth it in the long run.
However people iLounge to approve The iPhone 6’s ability to draw 2.1A smoothly means users can use larger 10W iPad chargers and charge their iPhone 6s faster than a regular 5W iPhone charger.
When using a 2.1A iPad charger to charge an iPhone 6, it takes about two hours to charge to around 90%, while with a 5W charger it takes quite a while.
2.1A charging support applies to both 4.7-inch iPhone 6 and 5.5-inch iPhone 6 Plus.
In earlier iPhones, it was recommended to charge these with the included 5W charger, mostly because using any type of larger charger wouldn’t really help much for the reasons mentioned above, and some experts even claimed that charging your phone was okay. A larger charger can damage your phone’s battery over time. However, it seems that the iPhone 6 can use iPad chargers without any problems.
So why does the iPhone 6 only come with a 5W charger by default?
Most likely due to production costs. These smaller 5W chargers are cheaper to manufacture than the larger 10W iPad chargers. As such, it’s Apple’s way of saving money and giving users smaller chargers to make a little more profit from iPhone 6 sales.
The iPhone 6 will charge just fine using a 5W charger, but it looks like users will finally get real benefits from using a larger 10W iPad charger.
Using a Non-iPhone Charger
Every smartphone comes with its own charger because every phone has different amount of amps, watts etc when it comes to charging. requires. However, there are cases where you can use a non-iPhone charger with your iPhone 6.
In short, most USB wall chargers will work with most smartphones, but there are a few things you’ll want to be aware of.
Ideally, you should use the charger that came with your iPhone to charge it, but in certain scenarios it won’t hurt to use a different charger as long as the amperage matches. It supports 2.1A with the iPhone 6, which means you can effectively use an iPad charger, but for older iPhones, 1A chargers are the first choice, and most smartphone chargers are between 1.0 and 1.5 amps.
For example, the Nexus 5 charger is set to 1.2A. So you might be asking yourself, since the Nexus 5 charger has more amps, wouldn’t it charge an iPhone 5 faster than a regular iPhone charger? Not exactly, while the Nexus 5 charger can technically provide more power than the iPhone needs, the devices only draw as much power as they can handle. Therefore, an iPhone will still only draw 1A from a 1.2A charger.
Regarding voltage and wattage, the only time you really need to worry about voltage when charging your iPhone is when you’re traveling to a different country. The US uses a completely different system than Europe, so you will need to get a voltage converter if you want to use your American appliances in the pond.
Otherwise, all USB devices are based on the 5V standard, so all USB chargers for all smartphones use 5V. Therefore, this is something you really don’t have to worry about.
The same goes for watts, but Apple markets various chargers by labeling them with their respective watt ratings. iPhone charger uses 5W while iPad charger uses 10W or 12W. A watt is nothing more than a measurement of volts multiplied by amps, and since all USB devices use 5V you really only need to look at the amperage rating to get an idea of how much power it can supply.
