The Guideline on How to Choose Portable Mobile Charger

September 11,2021

Happiness is a fully charged battery, a short break in a 3 seater sofa, and a cup of coffee filtered by delonghi ec702 portafilter. If you often travel in a car equipped with a auto sensor switch and a VW oxygen sensor, you will know how fast your mobile phones, tablets, mobile hotspots and other devices are running out, and you will also know the importance of compartment shoe beach bag and compression socks to you. A 4000mAh mobile charger deserves buying.


This is why I think it is essential to carry a portable charger, which allows you to extend the operating time without having to look for an AC power outlet (or put extra stress on your laptop by drawing power from the USB port).


There are many chargers on the market. If you don't know how to choose, this blog will give you some reference. Let's start with two basic concepts!

What is milliampere?


The battery capacity is measured in milliampere-hours (mAh), which is the "capacity required to allow 1 milliampere of current to flow for one hour." The larger the mAh, the more power the battery pack needs to charge your mobile device.


For example, if your phone has a 2,000mAh battery, you should buy at least one of 4,000mAh (twice the amperage) in order to be able to charge it several times.


Ampere output


Another important concept to know is the output amperage. Here are some facts:


  • Output 1A: The maximum output of this charger is 1000mAh/hour


  • Output 2A: The maximum output of this charger is 2000mAh/hour


  • Output 2.4A: The maximum output of this charger is 2400mAh/hour


Now, let's begin how to choose a suitable charger.


What factors need to be considered when buying a charger?




This seems obvious, but you can’t buy a portable charger without first knowing how many milliamps your device has. For example, if your phone has a 2,000mAh battery, you should buy at least one of 4,000mAh (twice the amperage) in order to be able to charge it several times.


Quality: Cheap eventually becomes expensive


If you have a cell phone made abroad that can remove the battery, would you buy a Chinese battery for $5? If the answer may be no, consider buying an extremely cheap portable charger may not be a good idea. Our company provides a lot of high-quality chargers, you can come and have a look at any time.


Batteries are very important to mobile phones. The higher the load quality, the more cycles it lasts. In our opinion, saving a few dollars and ultimately damaging the battery is not worth it.


New charging technology


With the arrival of the USB Type-C port and Quick Charge for fast charging of smartphones, the charger has entered a new stage. It is recommended to find a power bank with these technologies to charge your device faster. If even your smartphone supports the Type-C interface, then you should seriously consider using this option, even if the price of the relative portable charger is higher.


Know the charging status


Many portable chargers do not have an LED screen to display the remaining power. For high-capacity portable chargers, it’s important to know how much power is left while charging and to notify us that your battery is low. If you know how much power is left in the charger through the LED screen when you are traveling, you can plan ahead.


Weight and dimensions


Don't forget that you are choosing a portable charger, so we want it to be easy to carry and not put unnecessary weight on the shoulders when placed in a bag. Ideally, it is light and compact.


Avoid inferior power banks


This does not mean that low-priced products are of poor quality. Sometimes we make mistakes to save some money. It is recommended to choose a professional brand portable charger. If low-cost power banks fail the relevant safety inspections, they may explode and damage your mobile phone, or iPad, etc.


Know the number of devices that need a charger


It is unwise to only use portable chargers for smart phones. Choose a device that can charge three or more different devices, such as mobile phones, tablets, smart watches. When purchasing a portable charger, please pay attention to the number of USB output ports that can charge various devices together.


Search, compare and buy


When buying any products, it is necessary to follow the above steps. Comparison is the best way to choose the best product and the product that is most suitable for us to use. The same is true for choosing mobile power. Moreover, you will gain a lot of unexpected knowledge.


Hope the above content will help you to buy a charger.
