PowerBanks / Mobile batteries

The powerbank - your mobile energy source for on the road.

With a powerbank, you'll always be connected to the grid. You are often on the road and your smartphone or tablet gives up the ghost at the most inopportune moments? Then we have the solution - powerful powerbanks.

What is a powerbank?

A powerbank is a mobile power storage device that ensures you never run out of battery again. With various connections and a handy design, it offers you a reliable power supply when and where you need it.

You can use the portable power bank to charge electronic devices such as smartphones, tablets, and sometimes even laptops when a power outlet is not available. It usually consists of one or more lithium-ion or lithium-polymer cells in a rugged case that also includes ports for charging your devices and charging the powerbank itself.

How a powerbank works

A powerbank is basically a portable battery that can store and deliver electrical energy to other devices. The way a powerbank works can be broken down into three basic steps:

First, the powerbank is connected to a power outlet via a power adapter and a USB cable to be charged. During the charging process, electric current flows into the lithium-ion or lithium-polymer cells of the powerbank. This charging process causes the ions to move from the negative electrode to the positive electrode in the powerbank cell, storing energy.

The stored energy remains in the powerbank until it is needed. The performance and storage time of a powerbank depend on the quality of the built-in cells and electronics.

Charging times and battery capacity

The charging time of a powerbank depends on its capacity, charging speed and power supply. The larger the battery capacity, the longer the energy storage lasts - but the longer it also takes to charge the powerbank itself.

The golden rule of powerbanks: choose twice the capacity of your device!

Let's make this rule a little easier to understand: It is often recommended that your powerbank should have at least twice the battery capacity of your phone or tablet. Why is that? Well, Android smartphones usually have batteries with a capacity of 3,000 to 5,000 mAh, while iPhones tend to use batteries with 2,000 to 3,000 mAh. So by choosing a power bank with twice the capacity of your device battery, you can ensure that your device can be fully charged at least twice. This provides extra security and longer life for your phone or tablet when you're on the move.

Understand the power of your powerbank: What do 20000mAh and 50000mAh mean?

Have you ever wondered what those numbers like "20000mAh" or "50000mAh" on your powerbank mean? They are super important to understand how powerful your powerbank is!

"mAh" stands for "milliamp-hours". This is a unit that tells us how much energy your powerbank can store. Think of it as the "tank size" of your powerbank.

So if your powerbank is labelled "20000mAh", it can store 20,000 milliamp-hours of energy. That means, theoretically, it could supply a current of 20 amps for a whole hour.

But what does that mean for you now? Let's say you have a smartphone whose battery is 2000mAh. Theoretically, your 20000mAh powerbank could fully charge that phone ten times (20000mAh divided by 2000mAh equals 10).

The same goes for a 50000mAh powerbank. It could supply a current of 50 amps for one hour. And for your smartphone with the 2000mAh battery, this means that this powerbank could theoretically charge it 25 times (50000mAh divided by 2000mAh equals 25).

In practice, it will be less because there is always a bit of energy lost during the charging process due to heat and other factors. And of course, if you want to charge a bigger device like a tablet, that will need more energy.

So, these numbers are really just a guide and the actual number of charges can vary depending on the powerbank, device and how you use it. But now you know what these numbers mean and can better assess which powerbank is right for your needs!

Powerbanks: Universal energy source for a variety of devices

A powerbank is not just a handy companion for your smartphone. In fact, it is a universal energy storage device that can power a wide range of devices. Here are some examples:

Smartphones and tablets: these are the most common devices that are charged with a powerbank. Whether it is an iPhone, Android, iPad or Android tablet, a powerbank can charge these devices.

Laptops: Some powerful powerbanks can even charge laptops. This usually requires a high capacity powerbank with special connectors that support the higher power consumption of laptops.

Digital cameras and action cams: Many of these devices can be charged via a USB port, making them perfect candidates for charging with a powerbank.

Bluetooth speakers and headphones: These devices usually have smaller batteries and can therefore often be charged several times with a powerbank.

E-readers: devices like the Amazon Kindle tend to have a long battery life, but if you're going on a long trip, a powerbank can be useful to ensure you can keep reading.

Drones: Some portable drones can also be charged with powerbanks.

Wearable technologies: Whether they are smartwatches, fitness trackers or other wearable devices, a powerbank can charge them and prolong their operation.

Portable gaming consoles: Devices such as the Nintendo Switch can also benefit from a powerbank.

Please note that not all powerbanks are suitable for all devices. So when buying a powerbank, make sure it has the right power output and connections for your devices.

Powerbank or solar powerbank - Which is the right one for you?

There are two types of powerbank: the classic version, which is charged at the socket, and the solar powerbank for use on the go. Solar powerbanks use solar energy to charge the battery and thus provide an independent source of energy even if there is no power socket nearby.

Solar power banks are the ideal gadget for outdoor activities and keep your smartphone or tablet running even when there's not a power outlet in sight.

How a solar power bank works

The solar cells in the powerbank convert sunlight into electricity. The so-called photovoltaic effect plays a central role in this process. Electrons are released from their bonds by the sunlight and thus generate a direct current, which is then converted into alternating current to charge your devices.
