Stuffcool Giga Pro Max 20000mAh Power Bank Launched in India With 100W Fast Charging
tuffcool has launched the Giga Pro Max, a new 20,000mAh power bank designed for users who need fast charging for laptops, smartphones, tablets and other electronic devices while travelling or working away from a power outlet. The new accessory supports up to 100W power delivery and features a built-in retractable USB-C cable, eliminating the need to carry a separate charging cable for compatible devices.
Priced at Rs. 5,499, the Stuffcool Giga Pro Max combines high-capacity battery storage, multiple charging ports and a digital battery display in a portable design. It also supports simultaneous charging of multiple devices, making it useful for people who regularly carry a laptop and smartphone together.

The launch follows the company’s earlier Giga Max 25,000mAh power bank, which also focused on high-power charging. With the Giga Pro Max, Stuffcool is targeting users looking for a more convenient charging solution that can handle several devices without requiring multiple adapters and cables.
Stuffcool Giga Pro Max Price in India and Availability
The Stuffcool Giga Pro Max 20,000mAh power bank is priced at Rs. 5,499 in India. It is available through the official Stuffcool website and Amazon India.
The accessory is positioned as a premium power bank, particularly for users who want laptop-level charging performance rather than a product limited to smartphones and smaller devices.
Its combination of a built-in retractable cable, 100W maximum output and multiple ports distinguishes it from conventional power banks in the same capacity category.
Buyers should note that the maximum charging speed depends on the connected device, its supported charging protocol and the power bank’s output configuration.
Built-In Retractable USB-C Cable
One of the biggest highlights of the Stuffcool Giga Pro Max is its integrated retractable USB-C cable. Instead of carrying a separate cable, users can pull the built-in connector out when needed and retract it into the power bank after charging.
The integrated cable supports up to 100W output and includes an E-marker chip designed to support high-power USB-C charging. This makes it suitable for compatible laptops, tablets and smartphones.
The retractable mechanism also helps keep bags and desks organised by reducing loose cables. For frequent travellers, students and professionals who work remotely, this could be a particularly useful addition.
The power bank also features a digital display that shows the remaining battery percentage, allowing users to check the available charge before connecting their devices.
Stuffcool has included pass-through charging as well, enabling connected devices to charge while the power bank itself is connected to a suitable power source. Actual performance may depend on the connected charger and device combination.
100W Fast Charging and Multiple Device Support
The Stuffcool Giga Pro Max supports up to 100W output through its USB-C charging system. This allows it to charge compatible laptops and other high-power devices, provided they support the necessary USB Power Delivery standards.
The power bank includes three charging options: the built-in USB-C cable, an additional USB-C port and a USB-A port.

When charging two devices simultaneously, the integrated cable can deliver up to 65W while the secondary USB-C port supplies up to 35W. This provides a combined output of up to 100W.
Users can also charge a laptop through the built-in cable while connecting another device to the USB-A port. In this configuration, the cable can provide up to 65W and the USB-A port up to 18W.
For three connected devices, the integrated cable can deliver up to 65W, while the remaining 15W is shared between the additional USB-C and USB-A ports.
These power figures represent supported maximum output configurations, not guaranteed speeds for every connected device. When multiple devices are connected, the available power is distributed according to the selected ports and charging requirements.
The power bank supports Programmable Power Supply (PPS) and Samsung Super Fast Charging 2.0, helping it work with a range of compatible devices.
20,000mAh Battery Capacity and Charging Input
The Stuffcool Giga Pro Max packs a 20,000mAh battery rated at 3.85V, equivalent to 77Wh. This capacity is designed to provide additional power for smartphones, tablets and compatible laptops when access to a wall socket is limited.
For recharging the power bank itself, the built-in USB-C cable supports input power of up to 65W. The supported input profiles include 5V/3A, 9V/3A, 12V/3A, 15V/3A and 20V/3.25A.
Using a compatible high-power charger can help reduce the time needed to recharge the power bank compared with lower-wattage adapters.
However, charging time depends on the input power available, the charger’s capabilities, cable conditions and the battery’s current charge level.
The 77Wh rating is also relevant for air travel. The power bank’s stated energy capacity is below the commonly used 100Wh threshold for lithium-ion batteries carried in passenger aircraft cabins. Travellers should still check their airline’s current rules, since restrictions can vary.
Compact Design and Portability
Despite its high output and large battery, the Stuffcool Giga Pro Max is designed to remain portable.
The official product specifications list dimensions of approximately 14.3 x 7.2 x 3.25cm and a weight of around 407 grams.
Its compact rectangular body houses the battery, charging ports, digital display and retractable cable mechanism in one unit. The integrated cable reduces the number of accessories users need to carry separately.
At approximately 407 grams, however, the power bank is heavier than many smaller smartphone-focused models. Users looking for the lightest possible travel accessory may prefer a lower-capacity option, while those who need laptop charging may find the added capacity and output worthwhile.

Should You Buy the Stuffcool Giga Pro Max?
The Stuffcool Giga Pro Max is designed for users who want one power bank capable of charging several types of devices. Its 20,000mAh battery, 100W maximum output and integrated retractable cable make it particularly appealing to laptop users, remote workers and frequent travellers.
The ability to charge multiple devices simultaneously is another advantage, especially for people carrying a laptop, smartphone and accessories throughout the day.
