Always have power on hand with a power bank
A power bank, also known as a portable charger, is a portable, rechargeable battery that lets you charge mobile devices without needing a wall socket. You charge the power bank in advance using a cable, at home or at the office, and then you use the stored energy on the go to power your smartphone, tablet or other devices. You connect your device with a USB-C cable or another connector, and the power bank automatically delivers the power it needs.
The lifespan of a power bank depends on how often you charge it and how well you take care of it. Most quality power banks last between 300 and 500 charge cycles before their battery capacity noticeably decreases. With normal daily use, that means an average of two to four years. A sturdy design, overcharge protection and overheating protection all contribute to a longer lifespan. Store your power bank at room temperature and don't drain it completely when it isn't necessary; that way you'll keep it in good condition for as long as possible.

What kind of power bank should I choose?
When choosing a power bank, there are a few things to keep in mind. The capacity in mAh determines how much energy the power bank can store and how often you can charge your device. The power in watts determines how fast that charging goes. It's also handy to look at the number of ports: if you want to connect multiple devices at once, go for a model with several connections.
Also pay attention to the size and weight. A small power bank might be nicer, especially if you take the power bank with you every day. If you also want to charge a laptop, check whether the power bank supports USB-C with Power Delivery. Finally, the compatibility with your devices, whether it's an iPhone or Android, is always something to check.
What capacity power bank do I need?
The capacity of a power bank is expressed in milliampere-hours, or mAh. The higher this number, the more energy the power bank can store and the more often you can charge your device. Keep in mind that a power bank never converts its full capacity into usable energy; due to efficiency loss during charging, the effective capacity is slightly lower in practice. The table below gives an overview of which capacity suits which use.
For most people, a 10,000 mAh power bank is the best choice: enough capacity for daily use, without having to carry a heavy or large power bank. If you travel more often or want to be able to charge multiple devices, then 20,000 mAh or more is the sensible choice.
How much power should my power bank have?
Besides capacity, the power of a power bank, expressed in watts, is an important factor. The power determines how fast your device charges. A lower wattage is sufficient for smartphones and earbuds, but for tablets and certainly laptops you need a higher wattage. Fast charging via Power Delivery or Quick Charge also requires a minimum wattage. The table below helps you determine which power suits your devices.
For daily use of your smartphone, a power bank with 18 to 20W is sufficient. If you also want to be able to charge your tablet or laptop quickly, go for a model with at least 30W and Power Delivery support. That way you're helped quickly and efficiently in every situation.
Powerful power banks for every device
Power banks come in many shapes and sizes, tailored to a wide range of devices and use cases. The most common variant is the smartphone power bank: compact, lightweight and suitable for daily use by students or travelers. But there are also powerful models that can fully charge a laptop, thanks to a high capacity and USB-C with Power Delivery. For the outdoor user or camper, there are rugged, weather-resistant power banks that work reliably even in rougher conditions.
In addition, there are power banks with wireless charging, which let you charge your compatible smartphone or earbuds without a cable. Models with an LED indicator show how much energy is still available, so you're never caught by surprise. And for those who want to power multiple devices at once, there are power banks with multiple ports, including both USB-C and classic USB connections.
