Things to consider when buying a portable charger
Lots of people think that they will get the actual number of charges by dividing the battery’s mAh (milliampere-hour) rating by their smartphone’s mAh rating. However, it is completely wrong.
The reason being is, the usable mAh power of any portable charger is always less than what is described on the package. Another reason is that different smartphones charge at different voltage levels and current levels. So to know the actual number of charges of any smartphone, you need to calculate the watt-hour rating of both smartphone and power bank. Then and only then you can know for sure how many recharges any specific power bank will provide to your device.
That being said, you need to consider some factors before you choose any portable charger for your Samsung smartphone. We have put together a list of those factors so you can make a better buying decision.
1. Capacity
This is one of the most important factors when it comes to choosing any portable charger. The capacity of the portable charger is measured in mAh (milli-Ampere hour) or sometimes in Wh (watt-hour). The higher mAh battery contains more cells so it can store more energy, and as a result, you will be able to charge your Samsung smartphone multiple times.
2. Weight
The weight of the external battery bank depends on the number of cells it contains. So the portable charger with higher mAh rating is likely to have more number of cells that will increase the overall weight of the power bank. However, there are some higher mAh power banks out there, which are lightweight.
3. Number of output ports
When you want to charge two or three devices simultaneously, then having a power bank with at least three-output ports is a must-have feature. These days, almost all the portable chargers come with two output ports and the high storage capacity power banks, such as 26800mAh power banks come with three output ports. Also, not all the ports support the Quick Charge output, so look out for that.
4. Fast charging and recharging capability
If you don’t like to waste your time when charging your smartphone through the external battery pack, then having a Quick Charge compatible portable charger will give you an advantage. Any QC power bank will charge your Samsung smartphone from 0 to 60% in 30 minutes. But keep in mind that your Samsung smartphone should also be QUALCOMM Quick Charge compatible in order to fast charge your phone.
Similarly, if your power bank supports Qualcomm’s Quick Charge charging protocol as input, then the power bank will get recharged very quickly. So having QC as input and output in your battery pack gives you a big advantage.
5. Compatibility
When choosing any portable charger, you need to make sure it is compatible with your smartphone/device. For example, Qualcomm’s Quick Charge technology is not supported by Apple, so the QC power bank is useless for iPhones. Also, if you are buying the portable charger to charge a laptop or MacBook, then make sure it delivers enough wattage.
6. Recharge time of power bank
This is another great feature you need to look into the portable charger. Suppose you have a power bank that charges your phone at blazing fast speed, but what if it takes so much time to recharge the power bank itself. And this is important, especially when you are travelling and want to recharge your battery pack quickly.
Samsung’s Adaptive Fast Charging vs. Quick Charge 3.0/2.0 vs. USB-C PD vs. 2.4/3-amp Rapid Charging
All the smartphone manufacturers, including Apple, Samsung, Oneplus, and Redmi, use their respective fast charging technology. However, when it comes to power banks, there are few fast charging protocols are available, and they are compatible with most of the smartphones. Here we have explained some of the most known fast charging technologies/protocol that most power bank uses.
Qualcomm® Quick Charge 3.0/2.0 is a widely used charging protocol in most of the power banks as well as smartphones too. Brands like Samsung, Xiaomi and LG have adopted Qualcomm’s Quick Charge technology, and it is very fast (0 to 60% charge in 30 minutes). However, manufacturers need Qualcomm’s certification to use this fast charging technology in their device, which has limited the QC smartphone in the market.
USB-C PD (Power Delivery) fast charging technology was developed by the USB Implementers Forum (USB-IF), and Apple has implemented it in their iPhones as well as MacBooks and iPads. Any device compatible with USB-C PD can be charged from 0 to 50% in less than 30 minutes.
2.4/3-amp Rapid charging is used by iPhone 7 and lower models and other smartphones as well. Almost all the power banks today come with at least 2.4-amp charging/recharging speed, and it is way better than the old 1-amp chargers.
How fast charging really works
As I said earlier, all the different manufacturers use their respective fast-charging technologies to charge phones quickly.
The charging speed is measured by wattage, which is the product of voltage and current. So the higher wattage battery can be charged at faster speeds. Any battery that charges at a speed of at least 2A at 5V (10W) is counted as fast charging, whereas the basic USB specification can deliver the power of 2.5 watts (0.5 amps at 5 volts), which is very slow.
Now let’s understand what actually happens in the battery when charging at high speed.
Every battery has two electrodes in it, namely a positive terminal and a negative terminal. Due to the potential difference between two electrodes, the electrons flow from positive to the negative terminal and then to the smartphone. A chip called “charge controller” regulates the flow of electricity (current) going into and out of the battery. Generally, lithium-ion based controllers are used that controls the current by measuring the battery’s cell current and voltage. The higher current and voltage will result in faster charging of the battery.
What is Qualcomm’s Quick Charge?
This fast charging protocol is developed by Qualcomm, and currently, there are four versions of QC released. To take advantage of QC fast charging, you need QC compatible device as well as a USB cable.
Quick Charge technology charges the phone in two stages. In the first stage, it charges the battery at the higher current rate to decrease the charging time, but in the second stage, the charge controller decreases the current output (up to 2 amperes) to extend the battery’s life as well as to reduce the battery’s internal temperature.
All QC technologies, be it 1.0/2.0/3.0 or 4.0, are backwards compatible with one another. Many of Samsung’s smartphones are fitted with Qualcomm’s Snapdragon processors, but it doesn’t mean that it is Quick Charge compatible because it is an optional feature.
Recently released Quick Charge 4.0+ can also quickly charge the USB-C PD device; thus, it is compatible with QC as well as USB-C PD devices. QC 4.0+ can deliver a maximum of 18-watts of power in QC mode and 27-watts of power in USB-PD mode.
What is Samsung’s Adaptive Fast Charging?
Samsung’s Adaptive Fast Charging uses Qualcomm’s Quick Charge 2.0 technology. It’s just that Samsung has given it a fancy name just like other manufacturers.
This charging protocol allows the smartphone to switch the voltage output of the adapter to 5V, 9V, 12V, or 20V at current up to 3-amps using the USB D+/D- pins. So it will change the voltage output and current according to the charge level and battery’s condition.
All Samsung’s Smartphones, including Galaxy S10, S10+, S10e, S9, S9+, S8, S7, S6 and Note 10+, 10, 9, 8 and Galaxy A10, A20, A30, A50, A90 are QC 2.0 compatible whereas the Samsung Galaxy A70 & A80 come with QC 4.0 chip inside it for maximum charging speed.
What do I need to fast charge my Samsung smartphone?
First of all, you need to make sure that your Samsung smartphone supports QC 2.0 technology. Here are the list of Samsung smartphones that support the QC 2.0 or higher technology.
Now, to quickly charge Samsung smartphones that are QC 2.0 compatible, you need a QC compatible power bank and QC compatible charging cable. You can use the original cable of the phone, or you can use the MFi certified cable too.
As for the Samsung smartphones that do not support Qualcomm’s Quick Charge, you can use the 2.4/3-amp rapid charging power banks. Anker’s PowerIQ and RAVPower’s iSmart power banks are good choices for you.
