The Shargeek 300 is a Cyberpunk-style Power Bank that can charge two MacBook Pros

Power banks have spent years being boring on purpose. Black rectangles, white rectangles, the occasional textured finish. The category settled into a kind of utilitarian invisibility, as if the industry collectively decided that anything carrying electrons should look 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 catches light the way expensive things tend to. It belongs on a desk you’d actually want to show people.

Founded in 2020, SHARGE built its identity around the conviction that charging hardware deserves the same design attention as the devices it powers. The original Shargeek 100, launched in 2021, was the proof of concept: a transparent, display-equipped power bank with DC charging that found a devoted audience almost immediately. The Shargeek 300 is what four years of that bet looks like fully cashed in. It pushes 300 watts of total output, enough to charge two 16-inch MacBook Pros simultaneously while still fast-charging a smartphone on a third port. The 24,000mAh battery lands at 86.4Wh, sitting just under the 100Wh threshold airlines enforce for carry-on batteries. Recharge time from flat to full is 75 minutes with a 140W input. The whole unit is roughly the size of a 330ml can of cola. SHARGE spent 40 months getting here, and the result makes most rivals in the category look underprepared.

That meticulous attention to detail is most obvious in the physical construction. The main body is a matte silver CNC aluminum frame, which is then given a 180-grit sandblasted, anodized finish for a smooth, premium feel. The company’s head of production is even quoted as personally comparing the feel of every unit to an iPhone to ensure they are equally premium. The signature transparent casing is not just a window, but a piece of safety equipment, made from V0 flame-retardant, UL94-certified polycarbonate that resists both scratches and heat. The dual RGB light bars are fully customizable, allowing users to adjust brightness, change colors, and cycle through effects via the onboard display, turning a functional object into a piece of personalized desk art.

Inside that striking shell is technology that sets a new benchmark for portable power. The Shargeek 300 is the first power bank to use the same Full-Tab Battery Cell technology pioneered by Tesla. This design significantly lowers internal resistance compared to conventional cells, a change that unlocks faster charging speeds, higher sustained output, and superior heat dissipation. This internal efficiency is the key to how a device this compact can safely manage a 300W total output without overheating or degrading quickly. The advanced battery structure results in a longer-lasting, more stable power source that can handle the demanding, continuous power draws required by high-performance laptops and other professional equipment, putting truly next-generation power in your hands.

This power is routed through a versatile array of four output ports designed to handle nearly any device. The stars of the show are the two USB-C ports, both of which support the Power Delivery 3.1 standard to deliver a massive 140W of power each. This is what allows the Shargeek 300 to simultaneously fast-charge two 16-inch MacBook Pros at their maximum charging speed. A third USB-A port provides up to 20W for legacy devices and smartphones. The fourth and most unique port is the adjustable DC barrel port, a feature carried over from the Shargeek 100. It now supports up to 140W and its voltage can be manually set between 5V and 28V, unlocking compatibility with a world of gear that USB-C cannot serve, from professional camera equipment to high-performance drones. The 24,000mAh capacity provides enough energy for approximately one full charge of a modern MacBook Pro, six charges for an iPhone 16 Pro, or two charges for an iPad Pro.

The user experience is managed through a 1.9-inch IPS display, which is 60% larger than the screen on the previous model. It provides a level of control that is unheard of in this category. Beyond showing real-time input and output wattage, the display allows you to monitor battery health, track charging cycles, and check internal temperatures. You can use it to precisely adjust the DC output voltage, set a custom welcome message, and configure the RGB lighting. This smart display transforms the power bank from a simple battery into an intelligent power hub. This intelligence extends to its handling of delicate electronics. A dedicated Low-current Mode ensures that devices like earbuds, smartwatches, and fitness trackers receive a safe, optimized charge, preventing the overcharging that can damage the small batteries in those devices.

This combination of raw power and intelligent control is backed by a comprehensive suite of safety features, including overvoltage, undervoltage, short-circuit, and real-time temperature protection. This commitment to safety extends to its travel-readiness. Crucially, the power bank’s 24,000mAh capacity is engineered to a rating of 86.4Wh, keeping it comfortably under the 100Wh limit imposed by airlines for carry-on luggage. This makes it one of the most powerful charging solutions that can be legally carried onto a plane, a critical detail for mobile professionals. The low standby power consumption is another practical benefit, allowing the Shargeek 300 to retain over 90% of its charge after 15 days of inactivity. For anyone who has pulled a power bank from a bag after weeks only to find it unexpectedly dead, this is a genuinely valuable feature.

The Shargeek 300 starts at $199 but is available at a discounted $159 price for earlybird backers. Cobble together $209 and you can get the power bank along with its companion Pixel 140W PD 3.1 wall charger from Sharge with its adorable pixel-matrix display. The Shargeek 300 comes with a 12-month warranty, and ships globally as early as May 2026.

Sharge Forged Carbon Fiber Series Hands-On at IFA 2024: Power Banks with an Aerospace-grade Touch

At IFA 2024, where the latest and greatest in tech innovation often compete for attention, Sharge made its mark by introducing the Forged Carbon Fiber Series. Known for creating high-performance portable power solutions, Sharge’s new lineup captured the spotlight not only for its charging capabilities but also for its striking design. This collection, featuring the CarbonMag 10K MagSafe Power Bank, and the CarbonMag 5K MagSafe Power Bank, merges utility with premium materials, offering a standout option for those who demand both function and form from their tech accessories.

Forged Carbon Fiber: A Distinctive Edge

The use of forged carbon fiber in Sharge’s latest series is a significant design decision. Forged carbon fiber is a material associated with luxury and high-performance industries, such as motorsports and aerospace. It is strong, lightweight, and gives the devices a unique, patterned aesthetic. Unlike traditional woven carbon fiber, forged carbon is formed through a random compression process, resulting in each power bank featuring its own distinct, marble-like texture.

This design choice isn’t purely cosmetic. The forged carbon fiber exterior provides durability and resistance to everyday wear and tear. Whether you’re commuting daily or traveling, the rugged construction ensures that the power bank can handle a few bumps along the way without compromising its sleek appearance.

CarbonMag 10K: Lightweight Powerhouse

The CarbonMag 10K is the heavy hitter of the series, boasting a 10,000mAh capacity wrapped in a carbon fiber shell that offers both durability and portability. Its use of carbon fiber not only enhances its structural integrity but also keeps the device extremely light—perfect for users constantly on the move.

SHARGE Icemag Hands-On at CES 2024: A Cool-looking MagSafe Power Bank that Cools your Phone

Touted as the world’s first power-bank with its own turbo-cooling feature, the Icemag power bank keeps itself (and your phone) breezy while charging. An ultra-silent fan moves at speeds of 8000 RPM, actively cooling the battery pack inside while the Icemag wirelessly charges your phone, preventing anything from heating up during the charging process.

Sharge has pretty much solidified its reputation for building some of the most incredible-looking charging equipment of our time. Whether it’s the transparent 170W power bank with its own LED display, or the tiny yet indomitable Flow Mini power bank that’s small enough to blend right into your phone’s design, becoming its dedicated second battery, Sharge’s built a rather wonderful ecosystem of charging gear that’s both powerful and unmistakably eye-catching. The Icemag joins that ecosystem as a first for both Sharge and the world – the 10,000mAh MagSafe battery pack comes with its own active cooling system that pushes hot air out from around the lithium-ion battery, increasing its life and overall efficiency as it charges your phone. It also comes as a rather opportune time, as Apple silently killed its own MagSafe power bank, leaving a void in the marketplace.

The Icemag has the same proportions as Apple’s MagSafe power bank, albeit with that aforementioned cooling system and a whopping 10,000mAh battery that charges your entire phone twice over with enough extra juice left to spare for a third charge. It sports Sharge’s unmistakable aesthetic, with a transparent panel on the front that lets you peer into the electronics inside – namely the lithium ion battery, the PCB, and that active cooling system.

The active cooling system kicks in the second the Icemag is connected to a device (whether through MagSafe or via USB-C cable). The tiny fan outputs an impressive 8000 RPM, helping circulate air within the Icemag to keep the battery actively cooled (rather than relying on a metal heat-sink like other charging apparatus). The fan operates at a deadly silent <25dB, and it was practically inaudible in the buzz and chatter of the CES floor. What was noticeable, however, was the RGB lighting around the fan that changed colors as the Icemag juiced your device. It served as a nice visual indicator of the Icemag’s activity, especially given Sharge’s tech-geek and gamer-centric audience.

The compact power bank snaps satisfyingly onto the back of your MagSafe phone, beginning the charging process instantly. An indicator on the side shows exactly how much power the Icemag’s battery still has, while a USB-C port on the base supports both power in as well as out. This means the USB-C port can be used to charge the Icemag itself or can be used to connect the Icemag to another phone to charge it conventionally (without using the MagSafe wireless charging feature). The Icemag supports pass-through charging too, letting you charge it while it wirelessly juices your smartphone, and as far as charging speeds go, the Icemag’s wireless charging coil outputs a maximum 7.5W. If you want to tap into higher speeds, connecting your phone/device via USB-C gives you an output of 20W, charging your gadgets significantly faster for when you’re in a bind.

The Icemag balances its responsibilities of being handy, eye-catching, and functional rather well. It’s compact for its capacity and weighs just 223 grams (7.9 ounces), allowing it to securely attach to the back of your phone without any problems. The 10,000mAh battery is absolutely perfect for people who blow through their phones during the day, giving you an extra battery that can support your phone multiple times. The transparent aesthetic and active cooling system, however, steal the limelight for the gorgeous nerdy-cool aesthetic they give the Icemag. The term nerdy-cool probably gets used literally in this sense because of the Icemag’s ability to keep itself at manageable temperatures as it charges your phone. I dare you to find a MagSafe power bank that’s as gorgeously functional as this one…

SHARGE Flow Mini Hands-On at CES 2024: A Tiny yet Mighty ‘Power Backpack’ for your Smartphone

Power banks have a reputation for being bulky. Nobody really likes carrying them in their pockets given how large and heavy they can be, which often means most power banks spend all their time inside backpacks and purses. The Flow Mini, from Sharge (formerly Shargeek) has a different story to tell. It’s extremely handy, with a compact design that fits into pockets and even around your belt loop (should you choose) and a 5000mAh battery that’s enough to charge your phone. It also boasts a nifty transparent outer design that makes it the kind of power bank you wouldn’t mind flaunting to people around you. Measuring just about as wide as your smartphone, the Flow Mini practically ‘piggybacks’ onto your smartphone’s form factor, blending right into its design in ways that most power banks don’t.

Over the years, Sharge has pretty much nailed its core design DNA, focusing on functionality combined with a unique design that uses transparency to help create curiosity and a feeling of being able to see products for what they are. Sharge’s products aren’t for mere masses, they’re more aimed at people with a distinct penchant for design and power-use, as seen with their Shargeek 170, a whopping prism-shaped 170W charger with a transparent design and an LCD screen that lets you accurately measure the power output delivered to each port (along with things like battery percentage and other data-points). The Flow Mini, albeit too small to have its own display, comes with a transparent outer housing and a cylindrical base that’s reminiscent of pencil batteries or a roll of camera film (if you’re from that generation).

Designed to plug right into the base of your phone, it comes with an integrated port that lets the power bank itself attach to your device. This makes things a lot easier because you don’t need to hunt for a charging cable to connect your phone and power bank. However, the Flow Mini DOES have a cable that doubles as a lanyard or loop-grip when not actively in use.

The Sharge Flow Mini comes equipped with a tiny yet mighty 5000mAh battery that’s more than enough to take your dead smartphone from 0 to 100, or to juice your battery multiple times in the day for that extra boost.

The tiny design blends right into your phone’s overall form factor, allowing you to hold/ use your phone even with the Flow Mini attached. Perfect for people who prefer not carrying around a 10,000mAh brick along with them everywhere.

Given the fact that the world is still divided by USB-C and Lightning users (and will be for at least the next 4-5 years), the Flow Mini offers the option to alternate between USB-C and Lightning variants. The battery unit stays the same between both designs, with the only change being the primary port on the front. However, Sharge lets you detach the primary port and swap between USB-C or Lightning variants. Meanwhile, a lanyard/loop cable sits on the side, letting you charge another device simultaneously, or charge the Flow Mini itself by directly plugging it into a power outlet.

Th Flow Mini is Sharge’s smallest charger, but its size shouldn’t be taken for granted. While Sharge does make larger, powerful, and more feature-rich charging banks for the tech-nerd and power-user, the Flow Mini is perfect for on-the-go battery. In fact, the folks at Sharge call it your phone’s second battery, because plug it in place and it sits flush against your device, adding power to it without adding all that extra bulk and weight!
