Have you ever encountered one of these situations while traveling? Your smartphone battery is almost dead before you get home, or when you try to use it, it's already in low battery mode, or when you try to contact someone, it shuts down due to a dead battery. These situations are extremely frustrating, but it's precisely for these situations that this power bank was born.
What is a power bank? This is probably the first question that comes to mind for those who are unfamiliar with power banks. Today, we will explain what a power bank is from three aspects: definition, types, and how to choose the right one.
Power Bank Definition
What is a power bank ?
A power bank is a portable power source. It acts like a portable battery, powering mobile devices like cell phones, Bluetooth devices, and watches. In this high-tech age, a power bank not only charges your devices, but also acts as a safety net when you're on the go, allowing you to travel with peace of mind wherever you go.
Common uses for power banks
For example, when you're traveling or on a business trip, it's inconvenient to carry a charger with you, but a power bank can still serve as a backup battery. When you're commuting and can't find an outlet, a power bank plays an important role in keeping your smartphone connected. In other words, a power bank is your first choice for power when you're out and about, and it also ensures the safety of your smartphone's battery.
What types of power banks are there ?
There are many types of power banks, and different classification criteria will lead to different results. Here we will mainly distinguish them based on the three most common classifications.
By power bank capacity
As a backup power source, the capacity of a mobile battery is naturally the most important factor, so the most common way to classify them is by capacity. Based on capacity, they are divided into three main categories:
- Small Capacity ( ≤ 5000mAh ): Small capacity power banks are small and lightweight, and are primarily suited for everyday travel or emergency situations during commuting. They are highly portable and easy to carry. However, due to their low capacity, their battery life is relatively short, only enough to charge a mobile phone 0.5 to 1 time.
- Medium Capacity ( 5000-20000mAh ) : Medium capacity power banks are the most common type on the market. They are slightly larger and heavier than small capacity power banks, but naturally have a correspondingly larger capacity. They are practical and portable, making them suitable for travel and business trips, and can charge your phone approximately 2-3 times .
- High-capacity power banks ( 20,000mAh or higher): High-capacity power banks offer the longest battery life. However, they also come with a significant increase in size and weight. They are ideal for long-distance travel and outdoor activities like camping. They can charge a cell phone approximately 3 to 5 times. However, when using high-capacity power banks, be aware of restrictions on carry-on luggage. Power banks with a capacity exceeding a certain limit are prohibited from being carried on airplanes.
Classified according to power bank wattage and charging protocol
Based on power and charging protocol, they are divided into two categories :
- Standard power banks: Standard power banks have an output of 5W to 10W and only support the most basic charging functions, resulting in relatively slow charging speeds. However, due to their long history of development, the technology behind these types of power banks is relatively mature.
- Fast-charging power banks: Fast-charging power banks come in two power levels: medium -power fast charging and high-power fast charging. Medium-power fast charging is 18W to 22.5W , while high-power fast charging is 30W to 65W or higher. This type of fast-charging power bank is gradually becoming mainstream in the market because it significantly reduces charging time and is compatible with more devices and charging protocols. Of course, fast-charging power banks also have high requirements for safety and heat dissipation.
Classification of power banks by interface
Power banks are also categorized by their charging interfaces. The most common are USB-A , USB-C , and Lightning . Currently, power banks rarely feature all three interfaces individually; they are often used in combination. Some power banks have built-in charging cables, allowing multiple users and devices to be charged simultaneously. Of course, there are also power banks that can charge devices directly via Qi or MagSafe , eliminating the need for cables , making them more portable. For example, the newly released aulumu M10 features wireless charging pads on both the front and back, with a maximum output of 15W .
How to Choose the Right Mobile Battery
When choosing a power bank, let's go back to the original question: "What is a power bank?" By definition, a power bank is a portable power source that you use when you're out and about and don't have a power outlet. Therefore, when choosing a power bank, you need to consider the following points:
Use Cases and Capacity
When choosing the capacity of a mobile battery, it is important to first clarify your purpose. The capacity of a mobile battery will be greatly influenced by your frequency of use and needs. For daily commuting or travel, a small-capacity mobile battery is sufficient. For business trips or short trips, a medium-capacity mobile battery with a good balance of capacity and size will be suitable for any situation. If you need to use a mobile battery on the go, such as for long-distance travel or camping, a large-capacity mobile battery will give you peace of mind.
charging speed
In addition to capacity, charging speed is also an important factor when choosing a power bank for everyday use. Different charging speeds affect charging time. Typical 5W to 10W power banks take longer to charge, but their low output is stable and they don't overheat. Fast-charging power banks offer outputs above 10W (such as 15W and 18W ), as well as faster outputs like 30W and 65W . While fast charging significantly reduces charging time, charging too quickly can cause the power bank's temperature to continue to rise. Therefore, a proper cooling system is essential for fast-charging power banks.
Portability and detail
Portability is an essential feature for a power bank. For a power bank, portability is not only reflected in the availability of various charging interfaces, but also in the power bank's structure and performance. For example, there are wired and wireless power banks. Wired power banks do not require the use of a separate data cable, while wireless power banks require a separate cable.
Some power banks also support wireless charging, further eliminating the need for data cables, but compatibility with your smartphone must be considered. In addition to portability, the overall design quality of the power bank is also important, including whether or not it has a battery level indicator so you can instantly check the current battery level of the power bank.
safety
The most important thing to consider when purchasing a mobile battery is its safety. Certification standards vary from country to country. While some standards are not mandatory, they are industry standards. Therefore, before purchasing a mobile battery, you should check whether it meets the safety certification standards set by that country.
Aulumu M10 : The perfect portable power source for everyday use
Considering the above factors, the right power bank for most users should be one with a capacity of 10,000-20,000mAh, fast charging support, and a USB - C port. If you're still having trouble choosing a power bank, why not consider aulumu 's latest power bank, the M10 ?
The M10 has a total capacity of 10,000mAh , uses a USB-C interface, and has a maximum output of 35W . It weighs just 248g , roughly the same weight as a 250ml can of cola. In addition to the included USB-C cable, the M10 is equipped with two wireless charging slots, the front one of which is specifically designed for the watch.
In addition to its high performance standards, the M10 is packed with meticulous attention to detail. Both the front and back panels are equipped with ventilation holes to ensure safe charging and safety. The M10 also features two rows of power indicator lights, allowing you to quickly check the power bank's status. If you're still unsure which power bank to buy, try the aulumu M10 .
