Sandberg All-in-1 Laptop Powerbank 24000 mAh 420-57

The Sandberg 420-57 is a universal high-capacity 24,000 mAh (88.8 Wh) portable power station designed to charge a wide range of mobile devices, including laptops, MacBooks, tablets, and smartphones. This all-in-one power solution features a versatile array of outputs, including a dedicated DC port for laptops, two USB-C Power Delivery ports, a USB-A Quick Charge port, and an integrated wireless charging pad. Housed in a compact square-shaped chassis with a built-in LED display, it serves as a complete backup power bank for remote work, travel, and professional field use.

Universal Laptop Charging and DC Output

The main feature of the 420-57 is its powerful DC output port, which supports adjustable voltages (12V, 16.5V, 20V, and 24V) to meet the requirements of different laptop brands. The package includes a set of 12 different DC adapter tips, ensuring compatibility with most major laptop models. The DC output can provide up to 84 W of power, allowing users to operate and charge their laptops simultaneously when away from a wall outlet.

Multiport Architecture and Fast Charging

The power bank is equipped with four distinct charging zones to serve multiple devices at once:

* USB-C PD 1 (Input/Output): Supports up to 60W Power Delivery, ideal for modern laptops and fast recharging of the power bank itself.

* USB-C PD 2 (Output): Provides up to 27W, optimized for tablets and fast-charging smartphones.

* USB-A (Output): Features Quick Charge technology delivering up to 22.5 W for traditional mobile devices.

* Wireless Charging: A 10W Qi-compatible pad is integrated into the top surface for cable-free charging.

Smart Management and Digital Interface

An integrated LED digital display provides real-time information on the remaining battery percentage and the status of the active output. The power bank uses intelligent circuit management to prioritize power distribution; for example, the DC output has the highest priority and can automatically adjust the secondary port's power under heavy load. It also supports pass-through charging, allowing the unit to be recharged via the included AC wall adapter while powering connected USB devices.

Build Quality and Safety Features

Constructed from durable, heat-resistant plastic, the 420-57 is designed to be portable without sacrificing capacity. It includes a comprehensive suite of protections against short circuits, overheating, deep discharge, and overcharging. The kit comes with an AC wall charger, a DC-to-DC charging cable, and a USB-C to USB-C cable, providing a ready-to-use power ecosystem right out of the box.
