Shargeek 300 Previewed as World-First Up-to-300W DIY RGB Power Bank


In an era where portable power is more crucial than ever, the Shargeek 300 has emerged as a groundbreaking innovation—boasting the title of the world’s first DIY RGB power bank with up to 300W output. Designed for tech enthusiasts, gamers, and professionals who demand high-capacity, customizable charging solutions, this device is set to redefine power banks as we know them.

Unmatched Power and Customization

The Shargeek 300 isn’t just another power bank—it’s a portable powerhouse. With a staggering 300W max output, it can charge multiple high-wattage devices simultaneously, from gaming laptops to high-end drones. But what truly sets it apart is its DIY-friendly design, allowing users to swap modules, tweak performance settings, and even customize RGB lighting to match their style.

Key features include:

  • 300W total output (supports 140W USB-C PD 3.1, 100W USB-C, and 60W USB-A)
  • Modular battery system for easy capacity upgrades
  • Transparent design with RGB lighting (fully programmable via app)
  • Smart display showing real-time power usage, temperature, and remaining battery
  • Supports fast charging for laptops, phones, tablets, and more

A Power Bank Built for Enthusiasts

Unlike traditional power banks, the Shargeek 300 is designed with tinkerers in mind. Users can open it up to replace batteries, adjust cooling, or even add custom components—a rarity in the portable power market. The RGB lighting isn’t just for show; it can be synced with other devices or set to indicate battery status at a glance.

For those interested in backing this futuristic power bank, Shargeek has launched a Kickstarter campaign with early bird discounts. Check it out here:

How Does It Compare to the Competition?

While other brands like Anker have been pushing boundaries with high-capacity power banks (such as the recently upgraded Anker Prime 20000mAh), the Shargeek 300 stands out with its unprecedented wattage and customization options. Where most power banks focus on compactness, Shargeek embraces a hackable, feature-rich approach—appealing to power users who want more control over their gear.

Early Impressions and Availability

Early testers praise the Shargeek 300’s versatility and futuristic design, though some note that its size and weight make it better suited for travel bags rather than pockets. The Kickstarter campaign is already gaining traction, with shipments expected by early 2026.

Will this be the ultimate power bank for tech enthusiasts? Only time will tell, but one thing’s certain: Shargeek is pushing the limits of what portable power can do.
