Keep your devices charged on the go with a power bank. Here you'll find power banks with different capacities and fast-charging features.
Power Banks: Portable Power for Your Devices
Power banks are ideal when you need to charge devices on the go, such as smartphones, headphones, laptops or gaming handhelds. Here you'll find models with different capacities, charging outputs and convenient fast-charging features such as Power Delivery.
Which Power Bank Do I Need for My Device?
| Device |
Recommended Capacity |
Typical Charging Power |
| Smartphone |
5,000 to 10,000 mAh |
Approx. 20 to 30 W |
| Tablet |
10,000 to 20,000 mAh |
Approx. 20 to 45 W |
| Gaming Handheld |
20,000 mAh or more |
Often 45 to 65 W |
| Laptop |
20,000 mAh or more |
Approx. 45 to 100 W or more, depending on the model |
The capacity and charging power you actually need depend on your device. For gaming handhelds and laptops in particular, make sure the power bank provides sufficient USB-C output power for your device.
Wireless Charging with Qi2
Qi2 enables wireless charging with magnetic alignment. A compatible magnetic power bank attaches securely to the back of your smartphone, keeping the charging coils properly aligned. The available charging power depends on the power bank and the smartphone you're using.
USB-C, Multiple Ports and Built-In Cables
USB-C is particularly important for modern power banks, as it can support high charging outputs via USB Power Delivery, depending on the model. Multiple ports are convenient if you want to charge your smartphone, headphones or other devices simultaneously. Some power banks also feature a built-in USB-C cable, so you don't need to carry a separate charging cable when you're out and about.
FAQ – Power Banks
How Many Times Can I Charge My Smartphone with a Power Bank?
That depends on the capacity of the power bank and your smartphone's battery. Due to energy conversion losses, the full rated capacity is never available for charging. A 10,000 mAh power bank can therefore usually fully charge a typical smartphone more than once.
Can I Charge a Laptop with a Power Bank?
Yes, provided the power bank delivers enough power and your laptop supports charging via USB-C. For many laptops, 45 to 100 W or more is recommended. The specific requirements of your device are what matter most.
What Does USB-C Power Delivery Mean on a Power Bank?
USB Power Delivery, or USB-PD for short, is a fast-charging standard for USB-C. If both the power bank and the connected device support the standard, compatible smartphones, tablets, gaming handhelds and laptops can be charged at higher power levels.
Can I Charge Multiple Devices Simultaneously with a Power Bank?
This is often possible with power banks that have multiple ports. Depending on the model, the total available power is distributed across the ports in use, which means individual devices may charge at a lower wattage.
How Long Does a Power Bank Last?
The lifespan of a power bank depends on battery quality, usage and charging cycles. As with other lithium batteries, the maximum usable capacity decreases over time. Extreme heat, cold and regularly draining the battery completely can also accelerate wear.
