300W Max Total Output丨140W Max Input丨DIY RGB丨Premium Transparent & Alu Body丨Airline-safe 24,000mAh/86.4Wh丨Upgraded Smart Display
Check on Kickstarter
Back in 2021, SHARGE didn’t just launch a power bank – we sparked a movement with Shargeek 100 (originally Storm²), fusing bold transparency, smart displays, and DC charging into a 3421 backers and $520,000 sensation on Kickstarter in just 30 days, and a new chapter of power innovation was born.
Now, meet its heir after 4 years – Shargeek 300. Not just an upgrade, but a masterpiece. Sculpted over 40 months of relentless engineering and obsessive refinement, it’s the next-gen ultimate blend of raw power and premium elegance.
Welcome to the era of the 300W Power. Shargeek 300 rewrites what portable energy can be, while yesterday’s power banks stumble and clunky power stations hold you back.
Scroll down and see how Shargeek 300 raises the bar.
Just look at Shargeek 300. Matte Silver CNC aluminum body, accented by flowing curves, and crowned with our signature transparent design that dares to reveal the beauty within. A statement piece of functional art with elegance and sophistication.
Wherever you place it, it doesn’t just sit – it elevates.
We are talking about max 300W total output this time.
Results? You can fuel two 16″ MacBook Pros at 2×140W simultaneously, while still fast-charging up your smartphone at max 20W. All from just one Shargeek 300.
The story doesn’t stop at dual USB-C ports and one USB-A ports. True to the legacy of the Shargeek 100, Shargeek 300 retains the adjustable DC port and upgrades to max 140W charging, unlocking a world of compatibility beyond the ordinary: from high-performance drones to projectors and other specialized gear.
Shargeek 300 does what others can – and what they can’t.
Max 140W input. Get recharged from 0% to 100% in only 75 minutes.
Pair Shargeek 300 with our SHARGE Pixel 140W PD 3.1 Charger for a lightning-fast recharge — 0% to full in just 75 minutes — while powering up to 5 devices simultaneously with pass-through charging.
Stop risking your small gadgets on other chargers or batteries that weren’t built for them. Most power banks mishandle low-power devices such as earbuds, smartwatches, and fitness bands because they fail to meet the minimum current threshold, causing overcharging that may stress or even fry the batteries and circuits.
Shargeek300 masters both the highs and lows. With Low-current Mode, it delivers safe, optimized charging for your low-power gadgets to full capacity.
The massive 24,000mAh/86.4Wh capacity keeps devices on at any time, anywhere. So long, battery anxiety.
The Shargeek 300 is roughly the same size as a 330ml can of cola. For those on the go, it’s simply a matter of carrying a can of cola with you.
Oh, and no sweat at the airport: Shargeek 300 is totally airline-approved.
“Let there be light.”
Audi R8 dazzles with its iconic headlights, and Shargeek 300 shines with RGB. The dual RGB light bars are designed to sync with your style, mood, and personal space. Adjust brightness, change colors, switch RGB effects – Yes we are still talking about a power bank, not a gaming keyboard.
“That’s a bit gimmicky.” But hey, why not power your devices with more fun and style? Never settle for boredom.
Shargeek 100 made history as the first power bank with a full-color interactive display. Now, Shargeek 300 takes a step forward, coming with the most advanced smart display on a power bank.
The 1.9″ IPS display – 60% larger than Shargeek 100’s – provides clear, concise, and joyful interation of charging. It’s no longer just charging/recharging speed readouts, but here’s more:
- Monitor charging cycles and battery temperature.
- Set up the recharging battery level.
- Adjust the DC output voltage.
- Personalize the power-on welcome message.
- And, of course, customize RGB to match your vibe.

Details matter. Shargeek 300 is built with the finest components, materials, and finishes, delivering sophistication, safety, and enduring performance.
To harness the beast-like power of the SHARGEEK 300, only the most advanced, next-generation cell technology will do. As the world’s first power bank featuring the same revolutionary Full-Tab Battery Cell technology pioneered by Tesla, the Shargeek 300 fundamentally redefines performance.
Featuring a Full-Tab Battery Cell design that achieves significantly lower internal resistance compared to conventional battery cells, the Shargeek 300 unlocks unprecedented fast charging, higher output power, superior heat dissipation, and greater long-term reliability—putting truly next-generation power in your hands.
Inside, a compact, ultra-low-power PCB combines unique Shargeek aesthetics with serious practicality. With standby consumption under 500μA, Shargeek 300 holds over 90% charge even after 15 days — always ready when you are.
High-power charging generates heat. That’s why Shargeek 300 integrates a full aluminum alloy frame, an outer aluminum shell, and thermal silicone pads to whisk away heat efficiently. The result? Safer, more stable, and longer-lasting performance, even under demanding use.
Each 180-grit sandblasted, anodized aluminum casing is crafted for a premium look and a silky-smooth grip. “Every Shargeek 300 aluminum casing is first pressed to my left cheek, and an iPhone on my right cheek – to ensure they feel equally premium,” says Kailen, Head of Production at SHARGE.
The signature transparent casing isn’t just for show —it’s about safety. Made from V0 flame-retardant, UL94-certified PC, Shargeek 300 resists scratches and heat, ensuring both beauty and protection in every scenario.

Comprehensive protection system ensures Shargeek 140 connected with devices safe and sound.
You may view the all test video in Shargeek 300 Testing.
Using POWER-Z a third-party charging testing tool and , we verified Shargeek 300’s screen readings – nearly identical to lab instruments.
Note: Actual power may vary based on device protocols and cable loss.
With a 140W charger and PD load tester, Shargeek 300’s screen shows a max input of 138.2W, factoring in cable loss.
The transparent casing is crafted from Bayer’s V0-rated flame-retardant acrylic, passing UL 94 ‘s toughest standards:
Burning Time Requirements:
Single-flame application: Combustion must extinguish within 10 seconds.
Total flaming time for two flame applications: Must not exceed 50 seconds across five test samples.
No Flaming Drips:
The material must not produce flaming droplets that ignite cotton placed beneath the test specimen.
No Sustained Smoke Combustion:
The material must not generate continuous smoke during combustion.
Vertical Burning Restriction:
When vertically oriented, the burned area must not extend beyond 127mm (5 inches) from the base of the sample.
