Which power bank should I choose?

If you’re thinking about buying your first power bank, or if you’ve had one previously and are now wondering which the best power bank is, then you should know that there are a lot of things to consider before making your decision. What differentiates the different power banks can come down to their functionalities, how much charge they hold, and their size - and we have therefore put together a brief yet comprehensive guide that will help you make a decision, and keep you informed as a customer. Our goal is to help you navigate all the options and technical terms so that you can truly find exactly what you are looking for. Check out our collection of power banks. What is a power bank? Let’s start with a basic - which is what a power bank actually is. If you want to put it as simply as possible then it is a battery. If you want to go into a little more detail then a power bank is a portable battery device that allows you to charge your devices (such as your smartphone, smartwatch, tablet, headphones, or e-reader) when you don’t have access to a wall outlet. It therefore works like a backup electrical source that you can bring with you, storing energy that can be transferred to your devices via USB cable. They come in different sizes and capacities, ranging from small pocket-sized chargers that can recharge your phone once to larger models that can charge multiple devices at the same time, and several times over. 3 important things to consider when choosing a power bank As we stated previously, there are several things to consider when you are buying a power bank, and they all come down to what you are looking to get out of your purchase. For instance, maybe you just need something small and easy that you can keep in your bag for an emergency, or you need something more substantial to charge all of your devices when traveling or camping. Based on our experience, however, it mostly boils down to three main considerations: Battery capacity: When buying a power bank, battery capacity is a crucial factor to consider. The capacity, measured in milliampere-hours (abbreviated to mAh), determines how much charge the power bank can store. We always advise our customers to choose a power bank with a capacity higher than the battery capacity of the device its meant to charge. So, as an example: if your smartphone has a 3,000mAh battery, then that means a 20,000mAh power bank can charge it approximately 6 times. Amount of ports: Consider the number of devices you need to charge simultaneously. Power banks with multiple USB ports allow charging several devices at once, such as a smartphone and a tablet or multiple smartphones, providing convenient and flexible charging options. Functionality: When considering functionality in a power bank, decide between wired or wireless charging based on your needs. Wired power banks are faster and more efficient, while wireless models offer convenience by eliminating cables but charge slower. Additionally, consider the physical size—smaller power banks are lighter and more portable, while larger ones provide higher capacity but may be bulkier to carry. Different kinds of power banks at Lux-Case In our selection, you’ll find a wide range of different power banks - but what does that mean, and what sets them apart? The answer to that is that it comes down to a lot of different things, such as the amount of power it holds, what special functions it provides as well as its physical size and dimensions. To make it as easy as possible, we have divided it into three separate categories, based on what we know our customers consider important. Power banks with wireless charging Wireless power banks offer convenient, cable-free charging for compatible devices. They work through electromagnetic induction, using coils to generate a magnetic field that transfers energy to the device. The main benefits include portability, reduced wear on the device ports, and compatibility across multiple Qi and MagSafe-enabled devices. We would be remiss to not highlight the fact that compatibility with wireless charging is key, and if your device does not support the wireless charging Qi standard then the power bank will not work. Take a closer look at our most popular wireless power bank. Power banks with wired charging Wired power banks store electrical energy in an internal battery and transfer it to devices via USB cables, exactly in the same way as when you plug it into the wall at home. They offer several key benefits: faster charging speeds compared to wireless alternatives, efficient power distribution, and broad device compatibility. Most wired power banks feature multiple charging ports, allowing simultaneous charging of several devices. Additionally, they typically have higher battery capacities ranging from 10,000mAh to 30,000mAh, making them ideal for extended use. Additionally, wired power banks are generally more affordable and provide a direct, stable power connection that ensures quick and reliable charging for smartphones, tablets, and other electronic devices Our most powerful power bank with wired charging. Pocket-friendly power banks For a lot of people, the power bank must be as portable as the device it is intended to charge. This of course makes sense, since you might not want to have to bring a bag or have the bag you’re already bringing be weighed down, just for the convenience of being able to charge your smartphone or smartwatch while on the go. This is where a smaller, more pocket-sized power bank comes into the picture. The con of these products is that the smaller size means that they can only carry a reduced charge, but for many the convenience of being able to keep it in your pocket outweighs the cons. A small but incredibly useful smaller power bank. FAQ What devices can I use a power bank for? Power banks can charge a wide range of electronic devices, including smartphones, tablets, portable game consoles, wireless earbuds, smartwatches, and other USB-powered gadgets. They're versatile portable chargers that provide emergency power when you're away from electrical outlets, ensuring your devices stay charged during travel, work, or leisure activities. Can I bring a power bank on a plane? Yes, you can bring a power bank on a plane, but it must be in your carry-on baggage. Most airlines allow power banks up to 100 watt-hours, equivalent to approximately 27,000mAh. However, to be sure, we recommend that you always check your airline's specific regulations to ensure compliance and safety. How many times can a power bank charge my device? This is a good question and comes down to how much charge the power bank itself holds. As a rule of thumb, which might seem obvious, the higher mAh the power bank has, the more charges it also holds. However, this is also highly dependent on the size of the battery in your device, which can vary heavily from model to model. When it comes to the options in our selection, then you can consult the following to get an overview of what each mAh means: 5000mAh: A power bank with 5000mAh allows you to charge your phone 1 - 2 times, your smartwatch 10 - 15 times and will take most tablets up to a 50% charge. 10000mAh: A power bank with 10000mAh allows you to charge your phone 2 - 4 times, your smartwatch 20 - 40 times and your tablet once. 20000mAh: A power bank with 20000mAh means being able to charge your phone 4 - 7 times, your smartwatch 40 - 60 times, and your tablet roughly twice.
