The Intenso HE25000 25,000 mAh power bank, PD 3.1, fast charging, 3x USB (gray/black) is a powerful portable battery designed to reliably charge laptops and other electronic devices on the go. With a capacity of 25,000 mAh, it allows multiple charging of smartphones, tablets, laptops and other equipment without dependence on sockets, which is useful when traveling, longer trips or for everyday tasks.

The wired connection and support for the Power Delivery 3.1 fast charging standard enable fast and efficient charging even for devices with higher power requirements. The maximum output power of 140 W allows the product to be used even for laptops that require more power, which expands its usability compared to classic power banks for phones.

Key product features

⚖️ Compare features with other products of your choice

The large battery capacity means that users can charge more demanding devices, such as laptops or tablets, multiple times without worrying about running out of power. This makes the product particularly suitable for students, business users or those who travel a lot and need a reliable power source for extended periods without access to an electrical outlet.

With three available ports, it allows you to charge up to three different devices simultaneously – two ports are USB-C and one is USB-A. This provides flexibility in use, as you can charge, for example, a laptop, phone and headphones at the same time. Support for fast charging and the latest Power Delivery standard allow you to charge compatible devices in a shorter time, which is important in more intense daily rhythms or when time is limited.

The built-in LED display ensures that information about the remaining energy is always available, so the user knows exactly how much charge is left. The included USB-C cable allows for immediate use without the need for additional purchases.

The compact and modern design in gray-black complements the functionality, as the device remains convenient to carry in a backpack or bag. The power bank is therefore intended for anyone who wants to charge their electronic devices anywhere, faster and more reliably.

It is important to know

Before purchasing a power bank with such a high capacity, it makes sense to consider which devices you will charge most often, as this will affect the user experience. There are important trade-offs between size, portability, and capacity that are not directly reflected in the numbers in the specifications. Also, pay attention to whether your products support the benefits of high output power and fast charging.

• The large power range (140W output) allows you to charge more demanding devices, such as laptops - but compared to basic models, the power bank is slightly larger and heavier in your bag.
• When charging multiple devices simultaneously, the total power is divided, so the maximum charging speed is not always guaranteed for each device.
• Due to its considerable capacity, the model is very suitable for longer trips, but somewhat less so for everyday carrying in your pocket.
• The power bank does not support wireless or magnetic charging (MagSafe), so charging is always only possible via cable.

In practice

🟢 Backup phone charging on the go

The power bank allows multiple charging of modern phones with a wired connection, and due to its high output and capacity, it is well suited for travel or extended periods of absence from electricity.

🟢 Charging a laptop or other powerful devices

With 140W output power and fast charging technology support, you can reliably charge many laptops, tablets, and even most modern high-power devices.

🟡 Charging multiple small devices at the same time

It is possible to connect three devices simultaneously, but the total output power is shared; if more energy-intensive devices are connected, charging is not equally fast for all.

🔴 Wireless or MagSafe charging

The product does not support wireless or MagSafe charging, so this method of use is not feasible with this model.

Answers to frequently asked questions

How many times can I charge an average smartphone from a completely empty power bank?

The actual number of charges depends on the capacity of the phone's battery, but most models will be able to charge the phone multiple times, usually at least 5-7 charges per power bank charge.

Can I charge a laptop and two phones at the same time?

Yes, the power bank allows you to charge up to three devices simultaneously via USB outputs, but the total available power is distributed appropriately between all connected devices.

Is this model suitable for fast charging newer devices?

Yes, it supports fast output (PD 3.1 and 140W), but you should also check if your chosen device supports compatible fast charging standards.

What type of cable is required to use all the connectors?

Depending on the type of connectors on the power bank and your device, choose the appropriate USB cable (e.g. USB-C, USB-A), as it is recommended to use supporting or included cables for optimal performance.
