Sandberg All-in1 Laptop Powerbank 25000

Sandberg All-in1 Laptop Powerbank 25000 is a portable power source with a 25,000 mAh lithium-ion battery designed to charge smartphones, tablets and laptops. It provides multiple smartphone charges or several additional hours of laptop use. The powerbank supports fast wired charging via USB-C and DC-in, offers USB-C, USB-A and adjustable DC output (12–24 V) for compatibility with many laptops, and includes a 15 W wireless charger on top. The unit is compact, weighs about 500 g and is intended as a backup power solution for travel, office use or when you are away from mains power.

Advantages

The powerbank combines a high 25,000 mAh capacity with multiple output options — USB-C, USB-A, adjustable DC and 15 W wireless — allowing simultaneous charging of several devices. Fast charging via USB-C or DC-in reduces recharge time for the powerbank itself. The adjustable DC output increases compatibility with laptops that accept DC input, while the built-in display provides status information during use. Its compact design and moderate weight make it easy to carry.

Suitable for

• Charging smartphones and tablets on the go
• Extending laptop runtime for remote work or travel
• Powering devices that accept 12–24 V DC input via adapters
• Charging multiple devices simultaneously (up to four connected at once)

When it may not be suitable

The powerbank may not be suitable for laptops that require proprietary high-wattage chargers beyond the adjustable DC output range or specific charging protocols not supported by the unit. It is not a permanent replacement for mains power for high-consumption devices and total runtimes will vary depending on device power draw and conversion losses.

How to use

Charge the powerbank via the USB-C or DC-in port before use. Connect devices to the appropriate output: place compatible smartphones on the wireless pad for 15 W wireless charging, plug USB-C or USB-A cables into the corresponding ports for wired charging, or use the adjustable DC output with a suitable adapter to power laptops that accept 12–24 V DC. Monitor the built-in display for remaining capacity and output status. Observe device charging indicators and disconnect when charging is complete.

What to consider before purchase

• Confirm your laptop’s required input voltage and connector type to ensure compatibility with the adjustable 12–24 V DC output and available adapters
• Check whether your laptop requires specific charging protocols or higher wattage than the powerbank can deliver
• Consider airline and transport restrictions for carrying batteries rated around 91 Wh
• Assess the number of devices you typically need to charge simultaneously and the expected runtimes

Usage recommendations

For best results, fully charge the powerbank before travel, use the USB-C input for faster recharging, and match the DC adapter polarity and voltage exactly to your laptop’s requirements. Avoid exposing the unit to extreme temperatures and follow manufacturer guidance for safe battery use.
