If you often travel or work in places without access to the power grid, you know how frustrating it is to watch the battery percentage of your devices drop rapidly. The good news is that the Swissten Power Line 50000 mAh with 100 W power is now available on Alza for 1 559 Kč with code ALZADNY20, which is the best price on the Czech internet. This power bank offers sufficient capacity and power for charging not only phones and tablets but also more powerful laptops.

Power and Capacity for a Full Workday and Weekend Trip

The main advantage of this power bank is the combination of a large capacity of 50000 mAh (185 Wh) and high power of 100 W. Thanks to Power Delivery 3.0 support, the Swissten Power Line can power even more energy-intensive devices like laptops.

Price: 1 559 Kč

According to customer reviews on Alza, the capacity is truly sufficient. User Ema from Bratislava states in her review that “the fully charged power bank charged my laptop 3 times fully from about 10% that the laptop had”. Another customer, Mária, confirms the endurance on trips: “10 days on the road, it charged phones one after another… and we returned with it still having 40% capacity”.

Another reviewer, Lukáš from Hostinné, shares more specific data: “The power bank powered 80 W for about 2 hours, so 160 Wh (stated 185).” Even though the real capacity is slightly lower than stated, it is still an above-average value that is more than sufficient for a multi-day trip.

Four Outputs for Charging Multiple Devices Simultaneously

The Swissten Power Line is equipped with four outputs: three USB-A and one USB-C. This allows you to charge up to four devices simultaneously, which is especially useful when traveling with family or in a work team. However, it should be noted that according to user experience, Power Delivery (100 W) only works when charging a single device – if you connect more devices, the power is divided.

Price: 1 559 Kč

To charge the power bank itself, you can use either the USB-C or Micro USB port. The charging speed depends on the adapter used, but with a powerful source, even this high-capacity power bank will charge in a reasonable time. As Jaroslav from Děčín notes: “Charging time (with a strong source, of course)” is among the product’s advantages.

The power bank supports several fast charging standards including USB Power Delivery 3.0, Qualcomm Quick Charge 3.0, and Huawei Fast Charger Protocol, so it can optimize charging for a wide range of devices from various manufacturers.

Practical LED Display and Other Features

Unlike standard power banks that only show battery status with a few LED diodes, the Swissten Power Line features a clear LED display that shows the exact charge level in percentage. Several reviewers appreciate this feature, including Adam from Mezouň and Petr from Prague, who confirms the “correct % indicator”.

An interesting feature discovered by Petr from Prague is the sleep mode: “5× press power button = sleep mode on/off. It’s not written anywhere, I just tried it.” This mode can be useful for saving energy when you are not using the power bank for an extended period.

The power bank has dimensions of 67 × 70 × 154 mm and a weight of 1200 g. These parameters place it among larger and heavier power banks, which is the price for high capacity. Adam from Mezouň points out the “weight – extremely noticeable, definitely consider purchasing from this perspective”. However, if you need a power source for several days on the go, it is a reasonable compromise.

User Experience: Pros and Cons

When browsing reviews on Alza, several recurring themes appear. The main advantages of the Swissten Power Line power bank include:

  • High Capacity – “Powers a 5V/1.5A device for 55 hours.” (Petr, Prague)
  • Fast Charging – “Charging speed from USB-C” (Lukáš, Hostinné)
  • Quality Display – “LED display” (Adam, Mezouň)
  • Laptop Compatibility – “Compatible even with a powerful laptop” (Adam, Mezouň)
  • Included USB-C Cable – “Included USB-C to USB-C cable” (Adam, Mezouň)

Among the disadvantages that users point out are:

  • High Weight – “Weight – extremely noticeable” (Adam, Mezouň)
  • Inability to Charge Power Bank and Laptop Simultaneously – “Cannot charge itself and a laptop at the same time” (Anonymous customer)
  • Limitations when Charging Multiple Devices – “Connecting multiple devices only works in slow charging mode” (Anonymous customer)
  • Outdated Micro USB Port – “(Micro USB, objectively outdated)” (Adam, Mezouň)

Tips for Maximizing Power Bank Usage

If you decide to purchase the Swissten Power Line, here are some tips on how to get the most out of it:

  • Use a quality charger with high power for faster power bank charging – ideally a 60W or 100W adapter
  • For the fastest laptop charging, use only the USB-C port and do not connect other devices simultaneously
  • Activate sleep mode (5× press of the power button) if you are not using the power bank for an extended period
  • Use quality and short cables – long and low-quality cables can reduce charging performance
  • Before traveling by plane, check the airline’s rules – power banks with a capacity over 100 Wh are generally subject to restrictions

Final Summary

The Swissten Power Line 50000 mAh 100W Power Delivery represents a powerful solution for anyone who needs a reliable power source on the go. With the current price of 1 559 Kč (with code ALZADNY20), it is an affordable option in the category of high-capacity power banks with fast charging support.
