The era of modern technology is impossible without the active use of mobile devices, and batteries often do not keep up with our needs. External batteries, or power banks as they are also called, have become an integral companion for those who value mobility and working autonomy.

For example, a portable charger for phones is called a power bank, which is especially convenient for keeping mobile devices charged on the go. When choosing them, you should be guided by a number of criteria: capacity, size, charging speed and additional functions. This will not only provide additional operating time for your gadget, but also avoid unnecessary costs for an unsuitable device.

Types of external batteries

By battery type:

  1. Lithium-ion (Li-ion) batteries are the most widely used due to their optimal combination of price and efficiency. They are distinguished by high energy density and relatively light weight, but they can suffer from the “memory effect”.

  2. Lithium-polymer (Li-pol) batteries are becoming more and more popular. They are lighter and thinner than lithium-ion ones, and the absence of liquid electrolyte in their composition makes them safer. But the cost of such batteries is also higher.

By form factor:

  1. Compact batteries, what is the name of the phone charger that you can carry with you for android, usually called portable chargers. They are suitable for emergency charging during short trips and are convenient to use due to their small size.

  2. High capacity batteries are heavier and take up more space, but they are able to charge your device several times from 0% to 100%, which is a solution to the problem of charging in conditions where there is no access to the mains.

What influences the choice of battery

Battery Capacity

Battery capacity is measured in milliamp-hours (mAh) and determines how long it can keep your phone running. It is important to consider not only the capacity declared by the manufacturer but also how much charge your mobile device requires for one full cycle.

Power output and fast charging

A modern portable phone charger – how to choose? Pay attention to the current output, which affects the speed at which the battery can charge your device. Modern power banks are often equipped with fast charging technology, but for it to work, it is necessary that the phone also supports a similar function.

Number of ports and inputs

To charge several devices at the same time or use different types of cables for charging, choose a battery with multiple USB ports. Some models boast additional ports, including USB-C or even built-in cables, making it much easier to connect various gadgets without having to carry additional cables.

Additional features:

Protection levelIncreased security and device durabilityRarely
Charge indicatorsEase of use and charge level controlOften
Built-in cables and lightingElimination of the need for additional accessories and visibility in the darkSometimes

Finally, don’t neglect the opportunity to purchase a battery that can be used without access to an outlet, which is useful when traveling and on business trips. What is the name of a phone charger for a phone without an outlet to charge? The answer is simple – this is a high-quality external battery that will provide you with freedom from electrical networks and confidence in the future.

Choosing an external battery will become easier if you pay attention to these characteristics. This will help you find the optimal balance between size, capacity, and additional amenities.

Rating of popular models

Descriptions of models

  1. Model A has high capacity and support for fast charging technology, making it ideal for long trips.

  2. Model B is notable for its ultra-light and thin design, making it very comfortable for everyday wear.

  3. The Model C offers multiple USB ports and even wireless charging, giving it functional flexibility.

Advantages and disadvantages

  1. One of the advantages of Model A is its rugged design and overload protection, but its weight may be burdensome for some users.

  2. Model B, for all its advantages, may have a slower charging speed compared to its larger counterparts.

  3. Model C may be more expensive than other models, but additional features may well justify its cost.

To sum it up

When choosing the perfect power bank, you need to consider your lifestyle, charging needs, and budget. Let’s summarize the key points to help you make the right choice:

  1. Weigh the need for capacity versus portability. Higher-capacity devices will provide longer battery life, but will be heavier and larger.
  2. Look for support for fast charging technology if your phone allows it, to save time.
  3. Use reviews and model ratings as a guide, but always check them in terms of your own needs.

By choosing the right external battery, you will not only gain an additional source of energy for your gadgets but also peace of mind that they will always work.

Frequently asked questions

Question: What capacity of an external battery is right for me?
The choice of capacity depends on how often you use the device and how long the trips are expected to be. For daily use, compact models from 5,000 to 10,000 mAh are suitable; for long trips – from 20,000 mAh and above.
Question: Do I need a device that supports fast charging?
If your smartphone supports fast charging technology, then an external battery with this function will significantly reduce the charging time of the device.
Question: Is it worth buying an external battery with multiple ports?
Yes, if you plan to charge several devices at once. This will be convenient, for example, when traveling when you need to charge your phone and tablet at the same time.
Question: Can I take an external battery on a plane?
Yes, but make sure that the capacity of your battery does not exceed the permissible limits for transportation on an airplane. Typically, this is no more than 100 Wh, which is equivalent to approximately 27,000 mAh.
Question: How do I know if the external battery is suitable for my phone?
Check whether the battery supports the output voltage and current required by your device. Also, make sure you have the appropriate cable to connect your phone to the battery.
