In a time when the battery capacity of our devices is constantly under pressure, a power bank has become an essential accessory. While smaller models are enough to save your phone for a day, there are situations (long trips, a weekend in nature) when you need a really decent supply of energy. And it is for these moments that the Swissten Power Line II comes into play with a huge capacity of 30 mAh. This is not a pocket power bank, but a robust energy station designed to keep all your electronics running for several days.
Design, construction and workmanship
At first glance, it is clear that Power Line II puts function first, not miniature dimensions. The body of the power bank is made of a durable combination of fire-resistant ABS plastic and polycarbonate. With dimensions of 14,6 × 6,8 × 4,1 cm and a weight of 603 grams, it is a device that you will definitely feel in your backpack. However, the weight is a logical tax for the extreme capacity. The design is simple and purposeful. The front side is dominated by a clear LED display that shows the remaining battery capacity in percent. This is a huge advantage compared to less accurate diode indicators. You always know exactly how much energy you have left. All ports are concentrated on one of the shorter sides, which makes it easier to handle cables.

Capacity and charging performance in practice
The main attraction is undoubtedly the 30 mAh capacity. In the real world, this means that modern smartphonesone With a battery with a capacity of 4 to 000 mAh, you can fully charge it about 5 to 000 times. This will give you confidence for several days, even if you use your phone, headphones, and other devices intensively.
The power bank offers solid charging performance. There are three output ports available:
- 2× USB-A ports: Each of these ports can deliver up to 22,5W of power, supporting fast charging for a wide range of Android devices and other electronics.
- 1 × USB-C port: This port serves as an output with poweronem up to 20 W (which is in accordance with the Power Delivery standard for fast charging of iPhones and other devices) and at the same time as an input for charging the power bank itself (with outputonem up to 18 W).
Thanks to these parameters, you can charge your devices significantly faster than with standard 5W chargers. The power bank itself can be charged in a reasonable time with the corresponding 18W adapter, although it should be noted that it takes some time to replenish such a huge capacity.

Port versatility and simultaneous charging
With three output ports, the Swissten Power Line II is ideal for users with multiple devices. You can charge your phone, headphones, and smartwatch at the same time, for example. However, it is important to know that when connecting multiple devices, the total power is divided between all ports (typically 15W), so charging individual devices will be a little slower. However, it is a great feature for situations where you need to keep multiple devices alive at once.
Final assessment
The Swissten Power Line II 30 mAh power bank is not for everyone. Its heavier weight and larger dimensions make it suitable for specific uses. However, if you are a demanding user, traveler, photographer, or simply want to be sure that you will not run out of power even during a power outage of several days, this model is an excellent choice. It offers a huge energy reserve, solid charging speed and flexibility thanks to three ports. The clear LED display is just a pleasant icing on the cake. It is a reliable and powerful workhorse that will not let you down when you need it most. The price is 000 CZK.

With one port you charge your phone, then macbook and then maybe an iPad and then you find yourself standing next to the power bank like a troll because it's only for one device.”
Today, a normal person changes everything at home to a C port and gets rid of a pile of cables for traveling. Not here to promote a shop that is essentially a ho..nu
