Powerbank Voltcraft VC-GP40 144000 mAh LiFePO4 USB PD 3.0 (100W), black, LED flashlight, status indicator

The Voltcraft VC-GP40 is a high-capacity powerbank with a 144000 mAh LiFePO4 battery designed to provide extended portable power for laptops, tablets, smartphones and other USB‑PD devices. It supports USB Power Delivery 3.0 with output capability up to 100W, includes an integrated LED flashlight and a multi‑segment status indicator to show remaining charge. The unit is finished in black and is intended for travel, field work and emergency backup applications where high energy reserve and stable output are required.

Advantages

This powerbank uses LiFePO4 chemistry, offering greater cycle life and thermal stability compared with some other lithium cells. With a large 144000 mAh capacity and USB PD 3.0 support up to 100W, it can charge a wide range of devices including many laptops and fast‑charge capable phones. The integrated LED flashlight adds practical illumination for outdoor or emergency use, while the status indicator provides a clear, at‑a‑glance view of available charge. Multiple protection features inherent to modern powerbanks help protect connected devices from overcurrent and short circuits.

Suitable for

• Charging laptops and USB‑PD compatible notebooks while travelling or working remotely
• Powering tablets, smartphones and cameras during extended outings or field assignments
• Emergency backup power for home devices during short outages
• Outdoor activities where an integrated flashlight and long runtime are useful

When it may not be suitable

Because of its very large capacity and LiFePO4 cell chemistry, this powerbank is comparatively heavy and may be less convenient for minimal‑weight backpacking or situations demanding the smallest possible size. Some airlines restrict or limit carriage of high‑capacity powerbanks in checked luggage; check carrier rules before travel. It is not a replacement for dedicated mains UPS systems for long‑term home power outages.

How to use

Charge the powerbank using a compatible USB‑PD charger connected to its input port until the status indicator shows a full charge. Connect devices using the appropriate USB cable to the USB‑PD output port(s); the powerbank will negotiate output voltage and current up to 100 W with compliant devices. Use the built‑in flashlight by switching it on with the designated button. Monitor the status indicator to plan recharging and avoid deep discharge. Follow the manufacturer’s instructions regarding charging times and recommended chargers to maintain battery health.

What to consider before purchase

• Verify that your laptop or device supports USB Power Delivery and check its maximum input power to ensure compatibility with 100 W output.
• Consider the physical size and weight relative to the intended use—high capacity typically means heavier and larger form factor.
• Check airline regulations if you plan to carry the powerbank on flights; carriers may limit capacity carried in cabin or checked baggage.
• Ensure you have appropriate USB‑C or other cables to connect your specific devices.

Usage recommendations

For prolonged device longevity, avoid keeping the powerbank at full charge or fully depleted for extended periods. Store in a cool, dry place and use a compatible USB‑PD charger for recharging. When travelling by air, place the powerbank in carry‑on baggage if allowed by the carrier, and allow time to recharge between multi‑day trips to preserve battery health.
