Sandberg Laptop Powerbank 20000 PD100W

The Sandberg Laptop Powerbank 20000 PD100W is a compact external battery designed to charge laptops and other devices on the move. It provides a usable capacity of 20000 mAh (74 Wh) and supports high-power USB-C PD output as well as adjustable DC output, a built-in UPS function for 12V devices and the option to accept DC solar input. The unit is flight-approved thanks to its sub-100 Wh rating and comes in a black finish with a built-in display showing charge status.

Advantages

This powerbank delivers up to 100W via USB-C Power Delivery for fast laptop charging and offers an adjustable DC output ranging from 3.3V to 24V for specialty equipment. It includes a 12V UPS function to keep connected devices powered during brief mains interruptions, supports multiple charging sources including DC car socket and solar panels, and allows simultaneous charging of the powerbank and connected devices. A built-in display provides clear status information.

Suitable for

• Charging laptops and USB-C devices that accept up to 100W
• Field equipment and specialized electronics requiring adjustable DC voltage (3.3V–24V)
• Travel, remote work, and outdoor use where solar or car charging is useful
• Situations requiring a compact UPS for 12V devices

When it may not be suitable

The powerbank is not intended for devices that require more than 100W from a single USB-C port or for equipment needing sustained high current above the specified output limits. It is also not suitable for uses that demand very long runtimes beyond the energy stored in a 74 Wh battery.

• Battery capacity: 20000 mAh (74 Wh)
• Battery nominal voltage: 3.7 V
• USB-C output: Up to 100W (Power Delivery)
• USB-A output ports: 1
• USB-C ports quantity: 1
• Output current: Up to 5 A (combined/output-dependent)
• Adjustable DC output range: 3.3 V–24 V
• Built-in 12V UPS function
• Charging sources supported: USB, DC (cigar lighter), solar
• Colour: Black

How to use

Charge the powerbank before use via USB-C, a DC car adapter or a compatible solar panel input. Connect a laptop or other device to the USB-C port to draw up to 100W via Power Delivery, or use the adjustable DC output for devices that require a specific voltage between 3.3V and 24V. The built-in display indicates remaining charge and output status. Enable the UPS function when the powerbank is connected to a 12V device that must stay powered during mains outages. Follow device-specific charging guidelines to avoid exceeding recommended voltages or currents.

What to consider before purchase

• Ensure your laptop or device supports USB-C Power Delivery and the required wattage (up to 100W)
• Confirm any device that will use the adjustable DC output accepts the selectable voltage range (3.3V–24V)
• Verify the 74 Wh energy capacity meets your expected runtime needs and is acceptable for air travel
• Check connector compatibility for solar or DC car charging accessories you plan to use

Usage recommendations

Use the USB-C PD output for fast charging compatible laptops and tablets, and reserve the adjustable DC output for devices that require a specific voltage. To maximize battery lifespan, avoid deep discharges and store the powerbank partially charged if not used for extended periods. When using solar charging, connect a solar panel with appropriate voltage/current ratings and monitor the built-in display to ensure proper charging.
