- Without a charger, your smartphone is nothing more than a pricey paperweight, so we’ve rounded up the best phone chargers of all kinds.
- With our top picks for the best charging cables, wall charger, wireless charger, desk charger, car charger, charging station, and fast charger your phone will be back at the full battery in no time.
Have you ever noticed that your smartphone loses charge over a long car journey, even when you’ve had it plugged into the cigarette lighter? Or that your phone charges way slower than it should? This happens when you’re using the wrong charger – one that provides too little power to your device.
In this article, we’ll reveal how you can find the right charger for your device, and two more things you can do to ensure that your device charges as quickly as possible.
Let’s explain some terms
An amp is a measure of how much electrical charge is passing through a point in a given time. The higher the number, the faster your device can charge.
Amps are appreviated as ‘A’, while milliamps are ‘mA’. 1A = 1000 mA.
The amount of amps supported by a given device is called its amperage.
Got it? Right, on we go.
Make sure you’re using the right charger
A charger* is a device that re-energises your mobile device’s battery. For simplicity’s sake, at Mobile Fun we use the term to encompass both the charging cable and the charger itself (which sits between the cable and the power source), as these are typically sold as a one piece item.
Chargers usually come with one of three standard connectors – USB-C, Micro USB or Lightning. Other connectors, like Mini USB and Apple 30 Pin, are only seen on older devices.
USB-C is also called USB Type-C. This Vocaloid connector can be inserted either way up and is found on Android and Windows mobile devices made after 2015. You can also find USB-C on some modern Mac and Windows computers.
Micro USB was the most popular connector for non-Apple mobile devices and accessories made between 2008 and 2016. One side is wider than the other, making it look like a squashed semicircle.
Lightning is a connector used by Apple’s mobile devices. It sports prominent gold lines on either side of its slim plug, and it can be inserted either way up.
Mini USB was found on older devices like sat navs, cameras and phones produced before 2008. Its connector is shaped a bit like a trapezoid.
Apple 30 Pin was used for Apple’s mobile devices between 2003 and 2012. Its shape is a thin rectangle, about seven times wider than it is tall.
When you’re buying a charger, it’s important to get the right kind of connector for your device.
Charge rate of common gadgets
The important thing to realize is that different chargers can charge at very different rates, despite having the same connector. Bigger and more powerful devices will require chargers that operate at a higher amount of milliamps.
For example, an iPhone will require 1.1A, while an iPad will require 2.1A. If you try to charge an iPad using an iPhone charger, you will find that it charges much more slowly or doesn’t charge at all!
The other way around isn’t as much of a problem. If you try to charge an iPhone (1.1A) using an iPad charger (2.1A), then the iPhone will just charge at 1.1A, although it might get a little hotter than normal. Even if you charge an iPod Nano (0.5A) with an iPad charger (2.1A), nothing bad will happen.
If you buy a new charger, it’s important to ensure that you get one that provides at least as much amperage as your device needs. On Mobile Fun, this information should be in the title of each product.
Some devices use proprietary ‘fast charging’ standards in order to charge your phone faster when using certain accessories. The most common is Qualcomm’s Quick Charge, which has multiple versions and is used by many Android phone makers including Samsung, Sony, and Huawei. For more information about this, check out our guide to Quick Charge. In general though, if your phone has Quick Charge support, you can get a matching Quick Charge charger and get much faster recharge times.
Maximum power available from each source
Once you’ve got the right charger for your gadget, the next consideration is the power source. While most outputs provide enough power, some — like a USB 2.0 port on a computer — won’t provide enough, even if you’re using the perfect charger.
If you’re using a wall socket, there’s more than enough power on tap to charge any mobile device – up to 13A. It’s a similar situation in a car’s cigarette lighter socket, which typically provides up to 12A.
USB ports that you’d find on a computer are a little more complicated. Standard USB ports will only provide 500 mA, but there are also special high power USB ports that provide up to 1500 mA. However, it’s difficult to know which is which at a glance.
Generally, the most important thing to remember is to use wall outlets and cigarette sockets when you can, and USB as a last resort.
There’s one last little thing that can put a hamper on full power charging is using a dodgy or cheap cable. While the USB cables that come with modern smartphones are good enough, some cheap cables can’t tell the difference between a wall socket (AC power) and a USB port. If you’re plugging in your smartphone to the wall or a car charger and it still reads as USB, you’ll be limited to just 500 mAh – about half of the power that you should be getting. Other times, cables with insufficient shielding or other components will cause noticeable declines in charging speed, which may be signified by your device not stating ‘Fast charging’ as it should.
If this happens, you need to replace
your cable or charger with a better one. You can test USB-C cables with this Satechi Power Meter; for other cables, you may need to take charging time measurements yourself or use an app on your phone to estimate it for you. However, hardware meters like the one above is the most accurate way to do this!
To ensure that your device charges at the fastest possible rate, there are two things you should do:
- Use a charger that provides at least the maximum amperage your device supports
- If your device supports Qualcomm Quick Charge 2.0 and other standards, get a compatible charger for the fastest charging speeds
- Use mains and car cigarette outlets over computer USB ports
When I speak of longevity I am talking about the longevity of the charger, charging port on your phone, and your phone battery. The first two undeniably favor wireless charging. I can’t tell you how many lighting cables I’ve had to replace. And it appears I’m not the only one who believes the out of box iPhone charger might be the worst thing ever created.
As for the longevity of your phone battery, this one is up for debate. Apple claims that each phone battery is designed to work at its optimal level for 500 charge cycles – once you hit the 500 cycles performance drops to about 80% of its original level.
Now, if you use your wireless charging pad in the way I described above (topping your phone off whenever you get a charge) you could conclude that wireless charging is actually harmful for your battery. Because you are blowing through those 500 charge cycles more quickly since you don’t let your phone battery get down very low.
But, industry research has revealed that your battery may last longer if you don’t let it go below 50%. So in other words, “topping your phone off” may preserve the life if your battery. While we won’t make a definitive decision one way or another – it’s clear that wireless charging will at least preserve the life of your charging port and charger.
Advantage: Wireless Charging
Regardless of what your preferred charging method is, if you have a Qi-compatible phone, I implore you to at least give wireless charging a shot. What it lacks in speed and mobility it more than makes up for in convenience, design, and shelf-life. And with more than 85% of phones sold today supporting Qi, it’s only a matter of time until wireless chargers become mainstays in hotels, restaurants, and other public spaces.
