It’s 2026, and carrying around bulky chargers still makes no sense. We got this. Available with US, UK, or EU plugs.
Tired of lugging around a laptop charger that feels like an actual brick in your bag? As our gadgets get slimmer and smarter, it's wild that the power adapters keeping them alive have remained so bulky. Rolling Square is here to fix that with the Supertiny 100W, an ultra-compact GaN charger that packs a massive punch in a ridiculously small footprint. Weighing just 100 grams and roughly the size of your wireless earbud case, this little powerhouse proves that you don't need to sacrifice space in your everyday carry to keep your high-performance laptop, phone, or tablet 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 an AirPods 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 to a high-end laptop.
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 dollars, representing a solid discount off the planned 60 dollar 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, with global fulfillment to backers scheduled 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.
