Team behind the Kickstarter-funded Shargeek 100 power bank (originally Storm²) launched back in 2021, is back with its upgraded version. The all-new Shargeek 300 is developed over 40 months of continuous engineering and refinement, which gives a boost in terms of power, capacity and aesthetics as well. The power bank comes with a huge 24,000mAh/86.4Wh battery featuring a 300W maximum output across its four available ports. This can be a helpful gear for professional creators and tech enthusiasts who need high-wattage power, especially when a wall outlet is not nearby.
The size of a handheld coffee maker, the Shargeek 300 features Full-Tab Battery Cell technology, similar to Tesla vehicles for improved heat dissipation and efficiency. It is powerful enough to handle high-demand devices like gaming laptops. The maker claims, “You can fuel two 16″ MacBook Pros at 2×140W simultaneously, while still fast-charging up your smartphone at max 20W.” The battery bank includes two USB-C ports (PD 3.1) capable of 140W each, and one USB-A port providing up to 20W. There is also a dedicated DC barrel port that can be tuned between 25W and 140W for connecting with monitors, routers, and studio equipment.
The power bank supports up to 140W input, which allows you to charge it 50 percent in approximately 20 minutes or a full recharge in 75 minutes. It also comes with a low-current mode that delivers optimized charging for low-power gadgets. The maker says it can hold over 90-percent charge even after 15 days.

Shargeek 300 features a full aluminum alloy frame, an outer aluminum shell, and thermal silicone pads to whisk away heat efficiently. Each casing is made from 180-grit sandblasted, anodized aluminum for a premium look and a smooth grip. The transparent design adds a unique charm to the design by showcasing the beauty of internal components. There are also onboard dual RGB light bars that can be adjusted for color, brightness, and effects directly through the on-device menu.
The onboard 1.9-inch IPS display is not limited to just charging/recharging speed details. It can provide real-time data on input/output wattage, battery temperature, remaining capacity, and charging curves. You can also monitor charging cycles and battery temperature, set up the recharging battery level, adjust the DC output voltage, personalize the power-on welcome message and customize RGB to match your vibe.
Measuring 6.25 x 2.44 x 2.08 inches, the Shargeek 300 power bank weighs about 750 grams (about 1.65 lbs). Each unit comes with a charging cable and storage pouch that allows you to carry it safely in a backpack. If wishing to buy, it can be pre-ordered from Kickstarter for $149 right now, with delivery expected in May 2026.
