Here is a detailed post about How To Identify Fast Charging Cable. So, if you have been searching for how to identify fast charging cable iphone, how to identify fast charging adapter or other keywords online, then this article is dedicated to you. It contains how to recognize fast charging cable. Read on to enjoy all these and more.

Because we use our smartphones a lot these days, it is quite important that they have huge battery capacity and more important that they charge faster. Thanks to Quick Charge technology and all other forms of proprietary fast charging technologies from several OEMs, few minutes of charge can provide enough battery juice sufficient for hours of smartphone usage. If you are looking to buy a new smartphone in this age and time, fast charging is definitely one of the features to look out for.

While fast charging technology may be built into your device by default, the accessories you use to charge your devices also go a long way in determining how fast (or slow) your device charges. Cables vary in terms of how fast they charge, durability, length, price, and other factors.

How To Identify Fast Charging Cable

Fast charging cables vs. Regular cables

There are different types of USB cables even though they are not exactly easy to tell apart, physically. And yes, USB cables can also impact how quickly your device’s battery would get to 100%. Typically, to enjoy the fast charging speed of a device with quick charging technology, you must ensure that you’re also using a fast charging power brick and a fast charging cable.

But what differentiates a regular cable from a fast charging cable? The amount of power sent to your device’s battery at a given time. Compared to regular cables, fast charging cables are able to send more current to fill up your battery’s capacity quicker than a regular cable.

Regular USB cables send about 2.5 watts of power to your smartphone’s battery while fast charging cables (depending on the manufacturer and your model of your smartphone) can send as high as 120W or power to your battery. Xiaomi’s Super Charge Turbo charger, for example, comes with a fast cable that can supply as high as 100W to a battery. Vivo’s FlashCharge, which is capable of charging 4,000mAh battery in 13 minutes, comes with a fast charging cable that can send up to 120W of power to a battery.

If you use a regular USB cable to charge and a fast charging power brick/adapter to charge a smartphone, you will definitely not get fast charging speed. This is because the regular cable is limited in the amount of power it can send to a device.

As mentioned earlier, how fast a cable charges depends on the amount of power yhe built to carry. This is equally dependent on the size of the wire inside the cable; it’s simple physics.

A wire is limited in the amount of current it can transfer therefore a larger wire can carry more current.

The wires you’d find inside a regular USB cable are usually standard-sized 28 guage wires while fast charging cables have bigger/thicker 24 guage wires which allows for more current to be supplied to a battery of the same size. See the image below for better pictorial representation of the size difference between a 28 guage wire and a 24 guage wire.

The standard wires in a regular USB cables can supply about carry about 0.5A of current while fast charging cables are capable of carrying larger currents (2A or more).

Identifying Fast Charging cables

Because all cables have no easily identifiable features that distinguishes them into standard and regular cables, it is always difficult to tell a regular cable from a fast charging cable. Same way it is to differentiate data cables from charge-only cables. Nonetheless, there are still some easy ways to identify a fast charging cable should you need to buy one for your smartphone.

1. Check the label/description

Fast charging cables

Some cable manufacturers really make it easy for users to tell the type of cable they are about to spend money on. When picking up a cable, you can check the cable branding, label, or description for anything that points to the cable supporting fast charging. Some cables are properly labor as fast charging/quick charging so (potential) buyers know what they are signing up for.

2. Check for cable amperage

Another thing to look out for on a cable to determine of it is a fast charging cable is the amperage. As earlier mentioned, fast charging cables are capable of carrying larger currents of 2A or more. That said, if you need to buy a fast charging cable, be sure to pick out one labelled to support 2A of current or the specific current that enables your smartphone charge rapidly.

3. Thicker cables

Because fast charging cables have thick wires inside of them, it is commonly believed that thicker cables charge faster than their slim cable. This is sometimes true but it is not exactly an effective way of identifying a fast charging cable. However, for obvious reasons, you should shy away from purchasing ridiculously thin cables.

4. Buy from official/certified stores

To save you the hassle of identifying and differentiating a regular cable from a fast charging cable, buy cables from certified stores. More preferably, the store of your smartphone manufacturer. This is because some OEMs have their fast charging standard and specific cable requirements. If you purchase accessories from your smartphone maker, you are sure to be given a genuine fast-charging cable. Amazon is obviously a trusted online store and you can get Anker double-braided Nylong fast charging cables at just $12.99.

In a nutshell, if you have a smartphone that charges rapidly, having a fast charging cable is just as important as having a fast charging power adapter. They go hand in hand. It can get pretty confusing understanding why a cable charges faster than another but I hope it’s pretty clear now.

What You Should Know Before Buying A USB Charger

USB battery charging technology has greatly evolved over the years to enable the fastest possible charging solutions to portable devices like mobile phones, tablet computers, laptops, game consoles, bluetooth speakers, bluetooth headsets, portable projectors, cameras and virtually any other portable device that relies on a backup battery.

Back in the days when mobile phones first became mainstream in Nigeria, we typically had most phones with chargers rated at 0.5A and 5V output meaning the maximum power they were capable of producing to charge your device was 2.5W

Amperage x Voltage = Wattage

Today what we usually have with most USB chargers in the Nigerian market is a rating of 1A and 5V output meaning you get a maximum of 5W. If you are lucky, your phone, tablet or other mobile device will ship with a charger rated 2A and 5V output meaning you get a maximum of 10W to charge the device

Fast Charging Simplified

Most fast charging technologies termed as Quick Charge 2.0/3.0, quick charging, fast charging, adaptive fast charging, turbo charging and other similar terms usually fall around the same rating and are able to negotiate around 15-18W output depending on the maximum wattage your device is able to handle.

Some really high end phones currently support up to 30W and higher for charging but usually 30W and above mostly apply to tablets and modern laptops that charge with USB C or Type C charging ports like recent models of Macbooks, Dell XPS 13, Huawei Matebook X, HP EliteBook X360, Lenovo Thinkpad X1, Google Pixelbook, Xiaomi Air, LG Gram, ASUS Chromebook Flip and so many others.

The advent of USB C or Type C has given way for the introduction of Power Delivery (Usually termed as PD) charging protocol which is able to output a maximum of 100W to supporting devices.

The Reasons For Slow Charging

If you are having a frustrating experience charging your device and you want to take advantage of faster charging speeds, we have the solutions you need.

Slow charging is usually as a result of a low rated charger or a compromised charging cable. We will talk about chargers first and later go into cables.

You can start off by auditing the present USB charger(s) in your possession. All properly engineered USB chargers (wall chargers, car chargers, desktop chargers or multiport chargers) always have their specifications and ratings laser printed or inscribed on them in fine print. If your charger does not have it printed on, please throw the charger away and save yourself from possible harm or loss. Chargers that don’t have specifications laser printed or inscribed on them are inferior (or what we popularly call fake in Nigeria) and can pose a serious fire hazard or damage your devices. Same goes for chargers with specifications printed with ink that easily wipes off.

On your charger, you should look closely at the fineprint and check for the Output rating usually specified in Voltage and Amperage e.g. 5V 2A or 5V 1.5A and so on. Multiply the Voltage and Amperage to get the maximum capable output your charger can give you in Wattage. 

For most phones, 7.5W is pretty decent enough but if you want faster charging speeds you should go for 10W and higher depending on what your device can handle. 

Slow Charging Solutions

All Anker wall chargerscar chargers and power banks are capable of delivering 12W per USB port so essentially they are faster than most chargers currently in the Nigerian market. 

High end phones designed to handle fast charging speeds can take 18W upwards for blazing charging speeds.

Anker also has chargers that can deliver as much as 50W and powerbanks that can deliver as much as 45W to supported devices. 

Unlike most chargers, which are only optimized for one device, Anker chargers are designed to deliver the fastest possible charging speed to any device according to available charging protocols.

Anker chargers and powerbanks are very safe to use with MultiProtect 11 protection features built into them and come with 18 months warranty.

This is also a good time to point out that most devices are designed with a specific maximum Wattage they can receive from any charger. So in simple terms, if your phone is designed to handle a maximum of 10W to charge, a 30W charger will only deliver 10W to the phone and nothing more; but on the other hand, if you use a 5W charger, you will be experiencing only half the charging speed of what the phone is capable of. 

By the way, it is perfectly safe to use a well designed charger with a rating higher than your phone’s rating and that is why iPhones can charge with Macbook chargers without issues.

Your Cable May Be The Problem

Now let’s address the issue of compromised charging cables.

A charging cable can be compromised by design (poor and inferior design) or by wear and tear (after extended usage). A compromised charging cable impedes the flow of current through the cable and limits the amount of power that can be delivered to charge your phone efficiently (much like the effect of low current on your home appliances). 

Anker understands such limitations and developed the VoltageBoost™ technology to take care of such. VoltageBoost™ is an Anker-exclusive technology that compensates for cable resistance by smoothing voltage output. 

A compromised cable also limits your data transfer speed or makes it impossible to transfer any data over the cable. This is usually the reason your mobile device is not recognised by some computers when connected via the USB port of the computer.

In the event of a faulty cable that is not allowing a charge or data transfer at all, the cable will need to be replaced.

You should consider replacing your cable with our high quality Anker Powerline cables that are engineered to outlast every other cable and provide the fastest charging and data transfer speeds possible.
