Stuffcool has introduced the Giga Pro Max, a 20,000mAh portable power bank designed to charge high-draw devices such as laptops alongside smartphones and smaller accessories. This comes after the Giga Max 25000mAh 100W power bank that was launched last year.
The unit addresses common mobile charging bottlenecks by integrating a built-in retractable charging cable and supporting multi-device power distribution up to 100W.
Design and Integrated Cable Architecture
A central hardware feature of the Stuffcool Giga Pro Max is its built-in retractable USB-C cable, intended to eliminate the need for carrying loose cords. The cable incorporates an E-marker chip, enabling safe high-wattage power delivery up to 100W for compatible laptops, tablets, and smartphones. When not in use, the cable recoils flush into the power bank’s body.
The device measures 14.3 × 7.2 × 4.0 cm and weighs approximately 407 grams. It also features an integrated digital display showing the remaining battery percentage in real time, alongside support for pass-through charging, which allows connected hardware to charge while the power bank itself is plugged into a wall adapter.
Power Delivery and Output Configuration
The Stuffcool Giga Pro Max is equipped with a 77Wh (3.85V, 20,000mAh) battery cell, making it compliant with standard commercial airline carry-on regulations. It supports modern fast-charging protocols, including Programmable Power Supply (PPS) and Samsung Super Fast Charging 2.0.
The unit manages simultaneous multi-device output across its integrated cable, an auxiliary USB-C port, and a standard USB-A port using the following configurations:
- Dual Device (Laptop + Smartphone): Up to 65W via the built-in USB-C cable and up to 35W through the secondary USB-C port.
- Dual Device (Laptop + Accessory): Up to 65W via the built-in cable and up to 18W through the USB-A port.
- Triple Device Charging: Delivers up to 65W through the integrated cable, with a shared 15W distributed between the auxiliary USB-C and USB-A ports.
For recharging the power bank itself, the integrated USB-C cable supports input profiles up to 65W (20V⎓3.25A).
