The Sandberg Travel Powerbank 20000 PD65W (manufacturer number 420-95) is a mobile power source for use on the go, based on lithium-ion technology. The device features a high battery capacity of 20000 mAh (77 Wh) and enables the charging of up to two devices simultaneously. The power bank is black and has a rectangular design with dimensions 100 mm (height) × 63 mm (width) × 31.7 mm (depth). It weighs 339 g and is therefore compact enough for transport in a pocket or backpack. An integrated display shows the charge level, keeping the user informed at all times about the remaining battery status.

Applications
The power bank is suitable for mobile power supply of smartphones, tablets, cameras, and other USB-powered devices. Particularly notable is the support for Power Delivery (PD) via the USB-C port, which enables a maximum output power of 65 W. This makes the device suitable for charging notebooks that have a USB-C charging port. The USB-A port offers a maximum power of 22.5 W, sufficient to quickly charge smaller devices. The combination of both ports can deliver up to 65 W total power, with the load balanced between the ports.

Functions and Equipment in Detail
The device features a USB-C input supporting voltages from 5 V to 20 V with corresponding currents (3 A to 3.25 A), enabling flexible and fast recharging. The output power of the USB-C port is also up to 65 W, with adjustable voltage and current values (5 V/3 A, 9 V/2 A, 12 V/3 A, 15 V/3 A, 20 V/3.25 A). The USB-A port supports voltages of 5 V, 9 V, and 12 V with a maximum current of 4.5 A (at 5 V). The power bank supports fast charging via Power Delivery, enabling efficient energy transfer. The automatic shutdown ensures the device turns off when inactive, saving energy.

Technology Explained Simply
The lithium-ion battery offers high energy density and long service life. The Power Delivery technology enables intelligent power transfer, where the device automatically adjusts voltage and current to minimize charging time. The USB-C interface is bidirectional and can be used as both input and output. The USB-A interface is compatible with a wide range of devices featuring a standard USB port. The maximum output power of 65 W via USB-C is particularly suitable for devices with high power demands, such as modern laptops.

Compatibility and Accessories
The power bank is compatible with a wide range of devices featuring USB-C or USB-A ports. Support for Power Delivery allows use with devices that support this fast charging technology, including most notebooks. The included USB-C to USB-C cable (50 cm) enables direct connection to the device. The power bank is not designed for simultaneous charging and use (power-through), meaning it cannot be charged while simultaneously powering another device.

Mounting and Installation
The power bank requires no mounting or installation. It is simply connected to a charger or power source to recharge. Connection to a device is made via the included USB-C cable or via the USB-A port with an appropriate cable. The operating instructions are included in the delivery and provide guidance for safe use.

Operational Advantages
The high capacity of 20000 mAh enables multiple charge cycles for smartphones and tablets. Support for Power Delivery and the high output power of 65 W via USB-C provide fast and efficient charging. The integrated display informs the user of the charge level. The compact design and low weight make the power bank a practical companion for travel, business trips, or daily use. Compliance with standards FCC, UKCA, CE, and RoHS ensures safe and environmentally friendly use.

The device is delivered with a USB-C to USB-C cable (50 cm), operating instructions, and a GPSR safety guide. The warranty is 5 years.
