Power Banks 15 000 mAh and more

Battery capacity plays a very important role in a power bank. It determines how many times you can use it to charge your mobile phone, tablet or smartwatch. As with external batteries, capacity is stated in mAh (milliampere hour) units. The higher the capacity, the higher the number of times you can charge your device from the power bank. However, this will also make the power bank more expensive and larger in size.

Power banks with a capacity of over 15,000 mAh can charge a laptop or MacBook in addition to a mobile phone, smartwatch, headphones, tablet or music player. Our flagship in this category is the Swissten Black Core powerbank with a capacity of 30,000 mAh. You don't need such a high capacity, but compact size is important to you? Then the Swissten Black Core power bank with a capacity of 20,000 mAh in a slim design is the ideal solution for you.

You can comfortably charge several devices at the same time from a high-capacity power bank. However, you have to take into account the larger dimensions of the power bank and the higher price. We try to keep the price as low as possible, which is why our best quality Swissten powerbanks can be afforded by practically everyone.

In the package you will usually find a power bank and a charging cable. An additional cable for charging the device needs to be purchased depending on the connector you need.
