At a time when power outages have become commonplace and a dead phone can leave us without communication with our families and the world, power banks have turned from a fashion accessory to a necessity.
But how do you buy one that won’t let you down at a crucial moment and will be really useful?
After all, the market offers a lot of options, and it’s easy to get confused by all those milliampere hours, watts, and other technical specifications.
Let’s figure out together how to choose the perfect power bank that will become your reliable source of energy in any situation.
- Capacity of the power bank
One of the most important parameters of a power bank is its capacity, which is measured in milliampere hours (mAh).
The capacity of a power bank determines how many times it can charge a device.
For example, if you have a smartphone with a 3000 mAh battery, then a 10000 mAh power bank will be able to charge it about three times.
- Selecting a container
In principle, we can say that the capacity of a power bank is a key factor to consider when buying.
Here are some examples below: 5000-10000 mAh: These power banks are ideal for everyday use.
They are lightweight, compact, and can fully charge your smartphone 1-2 times. 10000-20000 mAh: These models are suitable for traveling and long-term use.
They can charge your smartphone several times and can also charge tablets. 20000 mAh and more: These are powerful power banks that can charge not only smartphones and tablets, but also laptops.
Obviously, they will be heavier and larger, but they provide maximum autonomy.
- 3. Size and weight
When choosing a power bank, it is equally important to consider its size and weight.
As we mentioned above, more powerful power banks are usually larger and heavier.
If you need a power bank for daily use, it is better to choose a compact model that is easy to carry around, but for traveling, you can choose a larger model with a larger capacity.
- Types of outputs and their number
Modern power banks have different types of outputs so that different devices can be charged.
Standard USB ports are suitable for most devices, but it’s also important to look for USB-C ports, which provide faster charging and can charge the latest devices.
Some power banks have multiple outputs, which allows you to charge more than one device at a time.
- Charging speed
The charging speed depends on the output current.
Standard power banks have an output current of 1A to 2.4A.
If your smartphone supports fast charging, choose a power bank with an output current of 2A or more.
Fast charging technologies such as Qualcomm Quick Charge or Power Delivery will make charging even faster.
- Quality and safety
The quality of the power bank and its safety are very important.
Give preference to models with safety certification and protection against overload, overheating, and short circuits.
Reliable brands, for example: Anker, Xiaomi, Baseus, RAVPower, Aukey, produce high-quality power banks, and they all last a very long time.
- Useful additional features
Flashlight. Power banks with a built-in flashlight can be useful in the dark or when hiking. Solar charging. Models with solar panels allow you to charge the power bank from sunlight, which is especially convenient when traveling. Integrated cable. Some power banks have built-in charging cables, which is equally convenient and allows you to avoid carrying a separate cable.
- 8. Feedback and recommendations
And finally, we recommend that you read the reviews of other users before buying a power bank.
Reviews will help you understand how reliable and efficient a particular power bank is.
When choosing a power bank, remember that it is not just another gadget, but your personal island of stability in a world where energy can disappear at any time.
A properly selected power bank will give you peace of mind and confidence, enabling you to stay in touch, work and have fun despite any unforeseen situations.
