300W in a Soda Can: Shargeek 300 Brings Dual 140W Charging to Kickstarter
Packing 300W of total output into a chassis barely larger than a standard soda can is an exercise in thermal audacity. After first appearing as a concept at CES 2025, Sharge’s most ambitious power bank yet, the Shargeek 300, has finally moved into its crowdfunding phase on Kickstarter. While the market is flooded with generic plastic bricks, Sharge continues to corner the niche for high-spec "cyberpunk" hardware that prioritizes both raw wattage and industrial transparency.
Can You Really Power Two MacBooks at Once?
Beyond the primary USB-C ports, the unit includes:
-
USB-A Port: A 20W legacy port for phones or low-power peripherals.
-
Adjustable DC Port: A versatile barrel-style connection ranging from 25W to 140W.
-
Rapid Recharge: The bank itself supports 140W input, allowing a 0-to-100% top-up in 75 minutes.
For field users managing demanding mobile setups, this level of density means leaving several bulky wall adapters behind, provided the 24,000 mAh capacity covers your session length.
Cyberpunk Aesthetics and the Thermal Challenge
Sharge’s signature look—transparent shells and exposed circuitry—is on full display here. The Shargeek 300 utilizes a lightweight aluminum alloy frame that doubles as a massive heat sink. This is a necessity rather than a design flourish; dissipating the heat generated by a 300W draw is the primary hurdle for a device this size. Two transparent windows provide a clear view of the battery cells and internal boards, leaning into the DIY-industrial aesthetic the brand is known for.
The interface is equally high-contrast. A 1.9-inch integrated screen displays real-time wattage and battery health, while customizable RGB lighting provides a visual status indicator. It’s a flashy, "tech-as-art" approach that makes a standard battery pack look prehistoric by comparison.
Pricing and the May 2026 Shipping Hurdle
The Shargeek 300 is currently seeking backers via Kickstarter, with early-bird pricing set at $149. Once the campaign concludes and moves toward a traditional retail launch, the price is expected to climb to $199.
However, potential buyers should weigh the specs against the timeline. Sharge is targeting May 2026 for the first wave of shipments. Given that we are already in February 2026, a multi-month wait for a power bank—even one this capable—requires a level of patience that might give some users pause. For those who need a centralized, high-speed solution for dual-laptop workflows and don't mind the wait, the Shargeek 300 is a powerhouse in a very small, very loud package.
