How to choose a mobile battery

In order to choose the ideal mobile battery, it is important to know in advance what size and weight the product is and what features it has. First, let's take a look at some points to keep in mind when choosing a mobile battery.

Choose by size and weight (compactness)

A mobile battery that is often carried and used when going out. The compact size makes it convenient to carry. That's why, let's choose according to the usage scene based on the size and weight. The compact model is recommended for going out to the neighborhood, and the large capacity type is recommended for scenes that require a large capacity battery such as overseas travel and business trips.

For example, in the case of "Anker Astro E1 5200", which is said to be an ultra-compact size, you can see its compactness by comparing it with the size and weight of iPhone X.

Anker Astro E1 5200 iPhoneX
height 96mm 143.6 mm
width 43mm 70.9 mm
thickness 22mm 7.7 mm
weight 125g 174 g

Also, assuming that you will carry it around, it is important to check "is it a size that fits in your pocket" and "is it good to fit in your bag's pocket?" Assuming that you will use your smartphone while charging, you can choose a more ideal mobile battery by checking whether it can be stacked according to the size of your hand.

merit

・ It will not be heavy or get in the way in the bag.

・ You can choose the type that suits you better by considering the usage scenes such as daily use, travel and business trips.

Demerit

・ If you give priority only to compactness, you may feel capacity shortage.

Choose by capacity

The unit that expresses the capacity of a mobile battery is "mAh (milli amp-hour)". First, I will describe the capacity and the number of times a general smartphone is charged.

capacity Number of smartphone charges (approximate)
5,000mAh 1-2 times
10,000mAh 2-3 times
15,000mAh-20,000mAh 5-6 times

However, the above table is just a guide. In reality, the chargeable capacity may be small due to voltage conversion loss. When choosing a mobile battery based on capacity and the number of times the smartphone is charged, it is a good idea to choose a capacity with plenty of room.

In addition, typical smartphone models and battery capacities are as follows.

Model nameBattery capacity
iPhone XR 2,942mAh
iPhone Xs 2,658mAh
Xperia XZ3 3,200mAh
Galaxy S9 3,000mAh
AQUOS R2 3,130mAh

merit

・ The larger the capacity, the more times the battery will be charged.

Demerit

・ The larger the capacity, the heavier and larger the mobile battery.

Select by the number of ports

The "number of ports" of a mobile battery is the number of devices that can be charged at the same time. For models with low capacity, 1 to 2 ports are common, and for large capacity, 2 to 4 ports are common.

【2021年版】モバイルバッテリーおすすめ7選!

merit

・ By writing down the number of precision devices that you usually carry in your bag, you can determine the number of ports you need and make an appropriate purchase (notebook PCs, tablets, wireless earphones, heat-not-burn tobacco, handy fans, game consoles). Such)

Demerit

・ For low-priced models, charging multiple devices at the same time may slow down the charging speed.

・ It is important to check the maximum output value per port and the total output value of all mobile battery ports.

Other useful features

Quick charge function

The quick charge function is also convenient when you want to finish charging in a hurry. The quick charging standards for mobile batteries include:

・ Quick Charge ・ Super Charge ・ USB PD (Power Delivery)

Among them, "Quick charge" is recommended for Android users. The latest version of "Quick Charge 3.0" can now charge your smartphone about four times faster than conventional products. In addition, the "USB PD", which is currently attracting attention, is an excellent one with 20 times the power supply power compared to a standard mobile battery.

However, at present, smartphones and laptops do not need so much power, so it is not necessary to exert full power.

In addition, the following three points are the conditions for demonstrating the performance of USB PD, and all of them must be compatible with USB PD.

・ Mobile battery used for charging ・ Digital devices to be charged (smartphones, laptops, etc.) ・ Cables connecting digital devices and mobile batteries

Especially if you want to use it on a laptop computer, check the required wattage as well.

Solar charging function, advanced waterproof function

Recently, in addition to mobile batteries that can be used outdoors such as outdoors and camping, mobile batteries as a disaster countermeasure are attracting attention. In the event of a disaster, your smartphone may not always be able to be charged as you normally would.

Many solar type models are large capacity type (20,000mAh) and are ideal for disaster countermeasures. However, it is heavy and not always suitable for carrying. Therefore, it is a good idea to keep it in your backpack for disasters.

If you are conscious of carrying it around all the time, you can choose a lightweight and thin type of about 5,000mAh. Some of the latest backpacks have a USB port, you can insert a mobile battery, and you can connect the cable to your smartphone from the outside, so why not check that as well?

A mobile battery equipped with a flashlight-type LED light, such as ELECOM DE-M20L-3350BK, is useful for both outdoor activities and disaster countermeasures. In addition, the Anker PowerCore Solar 10000 with a solar panel released on September 3, 2020 is also attracting attention. Since it converts sunlight into electricity, it takes longer than charging from an outlet, but it is attractive that it can be used outdoors when electricity cannot be used or during a power outage.

If you place importance on outdoor use, it is essential to have a high level of waterproofing. However, the type with large capacity + solar panel + waterproof function is sturdy and heavy, so please select it according to your physical strength and usage scene.

Integrated cable (built-in cable) / with outlet / wireless charging compatible

It is a mobile battery that not only eliminates the hassle of carrying cables, but also has the advantage of being less likely to break. It's a pretty convenient type for those who charge frequently on the go. However, there are not many lineups with outlets.

In addition, in order to charge wirelessly, it is essential that the model is compatible with the "Qi standard". In the case of iPhone, all Qi standards are supported if it is 8 or later.

Type-C compatible

In 2014, "USB Type-C" was born as a USB standard that can transfer a large amount of data at high speed. The shape of the connector is flat and oval. In order to maximize the performance of USB PD, it is essential to use USB Type-C. However, not all USB Type-C supports USB PD. If you're considering using it with a USB PD that is expected to deliver up to 100W, use a cable that says it supports high-speed communication, such as the Anker USB-C & USB-C Thunderbolt 3 cable. Please purchase.
