How does a Power Bank work and which Power Bank should I buy?
Many people have one, or have heard the word "power bank" often enough. But what is it really? And how does a power bank work? It is also not entirely unimportant that you buy the right power bank. Below you will find all information about the power bank.
What is a power bank?
A power bank is a mobile (external) charger, which can be charged in advance. After the powerbank is charged, you can charge your smartphone, tablet or laptop. It is a handy product that allows you to charge your electrical appliances without an electrical outlet nearby. You can use it for example when traveling by train, bus or plane. But it is also a very useful application during a (multi-day) festival, on holiday or other occasions.
How do you charge a power bank?
You can charge a power bank using the supplied cable. This is in most cases a micro USB to USB Type-A cable. By connecting this cable to your home charger and plugging it into the socket, the power bank charges. There are also versions which need to be charged by means of the supplied power adapter. This is a power bank that is suitable for charging laptops. In addition to via USB or via a power adapter, you can also charge a single power bank with solar panels. Many power banks are equipped with a Li-Ion battery. However, there are now many power banks with a Lithium-Polymer (LiPo) battery. It is lighter in weight, more compact and is generally preferred over the Li-Ion battery.
Can a power bank be charged quickly?
In general, it takes quite a long time before a power bank is fully charged. This is because a power bank has a high battery capacity. How quickly a power bank is charged is at the output of an adapter. Most phone adapters have an output of about 1A. The adapters of tablets between 2A and 2.4A. With the tablet adapter and a corresponding charging cable that supports at least 2A, you can therefore charge your power bank faster than with a 1A adapter. You can best avoid USB ports from your laptop or computer. These often only deliver 0.5A to 0.9A, which makes charging the power bank extremely slow.
Different types of power banks
There are many different power banks available. For example, they vary in size, mAh values, design, whether or not a Quick Charge, whether or not an LED indicator and other extras. Which power bank you need depends on what kind of device you want to charge. Everyone also has a personal preference for a color, size, or no LED indicator and other extras.
Which power bank do I need?
The mAh values of power banks can be very different from each other. So you can already purchase one with a capacity of 1000mAh, but there are now also variants which have a capacity of up to 50,000mAh! To know how much mAh you need, it's good to know how much mAh your phone's battery has and how often you want to charge your device. If you know how much mAh your phone battery is, you can use a simple calculation to calculate how often you can charge your phone with the relevant power bank. You share the number of mAh of the power bank by the number of mAh of your phone.
Example:
The iPhone 7 has a battery with a capacity of 1960mAh. If you buy a 10,000mAh power bank, you can recharge 10,000: 1960 = 5.1, so 5 times your iPhone 7. Do you have a Samsung Galaxy S7 with a battery capacity of 3000mAh and a powerbank with 20.000mAh? Then you can charge 20,000: 3000 = 6.6 times your phone with the relevant power bank. So first see how your battery capacity is, how often you want to charge your phone and then see which power bank with which capacity you need. 
What can you charge with a power bank?
There are different devices to charge with various power banks. Above you have read how you find out which power bank you need when charging your phone. With a powerbank with a capacity up to 10,000mAh you can charge phones, a TomTom, Nintendo or PlayStation Portable.
