It’s 2026, and carrying around bulky chargers still makes no sense. We got this. Available with US, UK, or EU plugs.
We all know the struggle of packing for a trip and realizing your laptop's power brick takes up as much space as a pair of shoes. As our devices get sleeker, the chargers that power them have stubbornly remained bulky eyesores....until now. Rolling Square is back on Kickstarter with the Supertiny 100W, a GaN (Gallium Nitride) charger that completely redefines portable power. Weighing just 100 grams and roughly the size of an AirPods case, this pocket-sized powerhouse proves that you don't need a heavy brick to keep your high-energy laptops, smartphones, and even e-bikes fully charged on the go.
PROJECT OVERVIEW
Name and Creator: The Supertiny - 100W power, world's smallest size. by Rolling Square.
What It Is: The Supertiny 100W is an ultra-compact USB-C wall charger utilizing advanced Gallium Nitride (GaN) technology. Designed as an everyday and travel companion, it claims the title of the smallest 100W charger ever made, easily replacing massive laptop bricks with a unit that slips seamlessly into your pocket.
KEY FEATURES
Extreme Portability: Weighing only 100 grams and taking up barely any more room than a wireless earbud case, it drastically cuts down on the weight and bulk of your everyday carry.
100W GaN Technology: By using Gallium Nitride instead of traditional silicon, the charger is highly energy-efficient, runs cooler, and delivers enough power to fast-charge demanding devices like MacBook Pros and Windows ultrabooks.
Universal Compatibility: It supports major charging protocols like USB-C Power Delivery (PD) and PPS, ensuring it can safely and quickly charge anything from a low-power smartwatch or earbuds to a high-end laptop or compatible e-bike.
Fixed Regional Plugs: To maximize stability and keep the footprint as tiny as possible, the charger comes in three specific variations rather than using bulky interchangeable adapters. You can choose a US version (which features foldable prongs for maximum compactness), an EU version, or a UK version.
Premium Cable Included: The charger comes bundled with Rolling Square's highly durable inCharge Life braided USB-C cable, which features premium metal connectors and an integrated silicone strap for neat storage.
REWARDS
Kickstarter Pricing: Backers can grab the Supertiny 100W along with the braided cable for an Early Bird price of approximately $46 (or €40), representing a solid discount off the planned $60 retail launch price.
Options: Users can select the specific plug type required for their region (US, UK, or EU) when pledging.
Delivery: The campaign has quickly smashed its funding goals, raising hundreds of thousands of dollars within days, with global fulfillment to follow the end of the campaign.
CONCEPT
The core concept is Uncompromised Minimalist Power. Rolling Square believes that carrying around bulky chargers in 2026 makes absolutely no sense. By cramming massive wattage into a minimal footprint, they aim to give digital nomads and daily commuters a single, near-invisible power solution that handles every device they own without weighing down their bags.
INSPIRATION
The Supertiny 100W is the direct evolution of Rolling Square's highly successful 65W charger. After seeing how much users loved the ultra-compact 65W version, the engineering team wanted to push the boundaries of thermal management and GaN circuitry even further. They were inspired to crack the 100W threshold—the sweet spot for modern high-performance laptops—without sacrificing the incredibly tiny form factor that made their previous charger so popular.
