They say, “Good things come in small packages.” Fact substantiated again by Rolling Square, a Switzerland-based accessories maker that rocked the world with the smallest 65W GaN charger last year. Now for 2026, it has launched a new 100W charger, which the company says is the smallest ever made.
It’s called the Supertiny 100W GaN charger and is currently enjoying a successful crowdfunding run on Kickstarter. Rolling Square is disrupting design and functionality with great quality and exceptionally small size of this charger, which can power smaller devices like laptops, smartphones, and earbuds, and larger, high-energy guzzlers like e-bikes with similar ease.
“This is the smallest 100W charger ever made, offering powerful performance in an ultra-compact design,” making it an ideal “every day and travel companion.” Made in the size of a regular pair of your earbuds, the Supertiny is reckoned to be 65% smaller than Apple’s adaptor, making it the smallest in size for the level of power it generates.
The charger is powered by GaN chipset and features custom architecture, which helps reduce the size and keep the weight of the 100W charger in check. The size is drastically reduced by optimizing the voltage transformer and integrating heat conduction silicon and thermal sheets to help the charger maintain its temperature and dissipate heat evenly while performing at its peak.
The high-efficiency Supertiny 100W GaN charger weighs only 100g and features a clever ribbed design on the sides to ensure the charger feels cool on the outside when you are unplugging it after charging high-powered devices such as an e-bike or computer.
It has been engineered to meet all international safety standards and operates on 100–240V input. No matter where you are in the world, this 100W charger is easily usable thanks to its compatibility with EU, US, and UK foldable pins connectors. You can use an inCharge Life 2in1 USB-C nylon braided cable (available as an add-on) with the charger to power two devices simultaneously with 100W output “intelligently shared between devices for safe and efficient charging.”
If you’re willing to spend a little more, you can also get a compact pouch designed to keep the charger and an inCharge Life cable organized inside a backpack or purse. The Supertiny 100W GaN charger is available for preorder through Kickstarter at $47. A 100W charger and an inCharge Life 2in1 cable can be availed for $68 now. These are special discounted deals that won’t last long, so hurry while the early bird discounts last.
