Power banks have invested years being boring on function. Black rectangular shapes, white rectangles, the periodic textured surface. The category settled into a kind of practical invisibility, as if the market jointly chose that anything carrying electrons must appear like a bar of soap. SHARGE never got that memo. The Shargeek 300 looks like a prop from a near-future thriller, with transparent panels revealing glowing circuitry beneath, RGB light bars running along its flanks, and a CNC aluminum body that captures light the method costly things tend to. It belongs on a desk you ‘d in fact wish to reveal individuals.
Founded in 2020, SHARGE developed its identity around the conviction that charging hardware is worthy of the very same style attention as the devices it powers. The original Shargeek 100, released in 2021, was the proof of principle: a transparent, display-equipped power bank with DC charging that discovered a devoted audience practically immediately. The Shargeek 300 is what four years of that bet looks like totally moneyed in. It presses 300 watts of total output, enough to charge two 16-inch MacBook Pros all at once while still fast-charging a mobile phone on a third port. The 24,000 mAh battery lands at 86.4 Wh, sitting simply under the 100Wh limit airlines implement for carry-on batteries. Recharge time from flat to full is 75 minutes with a 140W input. The entire system is approximately the size of a 330ml can of cola. SHARGE invested 40 months getting here, and the result makes most rivals in the category appearance underprepared.

That meticulous attention to information is most obvious in the physical building and construction. The main body is a matte silver CNC aluminum frame, which is then provided a 180-grit sandblasted, anodized surface for a smooth, superior feel. The business’s head of production is even quoted as personally comparing the feel of every unit to an iPhone to guarantee they are similarly premium. The signature transparent casing is not simply a window, however a piece of security equipment, made from V0 flame-retardant, UL94-certified polycarbonate that resists both scratches and heat. The double RGB light bars are totally adjustable, permitting users to change brightness, modification colors, and cycle through results via the onboard display, turning a functional things into a piece of tailored desk art.

The Shargeek 300 is the first power bank to use the very same Full-Tab Battery Cell innovation originated by Tesla. This style considerably decreases internal resistance compared to traditional cells, a modification that opens quicker charging speeds, higher continual output, and remarkable heat dissipation. This internal efficiency is the crucial to how a device this compact can securely manage a 300W total output without overheating or deteriorating rapidly. The innovative battery structure results in a longer-lasting, more steady power source that can deal with the demanding, constant power draws needed by high-performance laptops and other professional equipment, putting really next-generation power in your hands.

The stars of the show are the two USB-C ports, both of which support the Power Shipment 3.1 requirement to deliver a huge 140W of power each. This is what permits the Shargeek 300 to at the same time fast-charge two 16-inch MacBook Pros at their maximum charging speed. A 3rd USB-A port supplies as much as 20W for tradition gadgets and mobile phones. The 4th and most unique port is the adjustable DC barrel port, a function carried over from the Shargeek 100. It now supports as much as 140W and its voltage can be by hand set between 5V and 28V, opening compatibility with a world of gear that USB-C can not serve, from expert video camera equipment to high-performance drones. The 24,000 mAh capability supplies enough energy for around one complete charge of a modern-day MacBook Pro, six charges for an iPhone 16 Pro, or two charges for an iPad Pro.

It offers a level of control that is unprecedented in this classification. Beyond revealing real-time input and output wattage, the display screen enables you to keep track of battery health, track charging cycles, and inspect internal temperature levels. You can utilize it to specifically change the DC output voltage, set a custom-made welcome message, and set up the RGB lighting. This clever screen transforms the power bank from a basic battery into an intelligent power center. This intelligence extends to its handling of fragile electronics. A devoted Low-current Mode guarantees that devices like earbuds, smartwatches, and fitness trackers receive a safe, optimized charge, avoiding the overcharging that can harm the little batteries in those devices.
This mix of raw power and smart control is backed by a detailed suite of safety features, consisting of overvoltage, undervoltage, short-circuit, and real-time temperature level security. This dedication to safety extends to its travel-readiness. Most importantly, the power bank’s 24,000 mAh capability is crafted to a score of 86.4 Wh, keeping it conveniently under the 100Wh limitation imposed by airlines for carry-on baggage. This makes it among the most effective charging services that can be lawfully carried onto an aircraft, a crucial detail for mobile professionals. The low standby power intake is another useful advantage, permitting the Shargeek 300 to keep over 90% of its charge after 15 days of inactivity. For anybody who has actually pulled a power bank from a bag after weeks only to find it suddenly dead, this is a genuinely important function.
The Shargeek 300 begins at $199 but is offered at an affordable $159 price for earlybird backers. Cobble together $209 and you can get the power bank along with its buddy Pixel 140W PD 3.1 wall charger from Sharge with its charming pixel-matrix display. The Shargeek 300 features a 12-month service warranty, and ships globally as early as May 2026.
