The Supertiny 100W charger on Kickstarter by Rolling Square is exactly what it claims to be: the smallest 100W GaN charger ever made. At 100 grams and roughly the same footprint as a pair of earbuds, it delivers laptop-grade charging power in a size that disappears into any pocket, bag, or carry-on. No bulk. No compromise on output.
The Supertiny 100W charger Kickstarter campaign has raised $379,112 from 3,902 backers against a $23,087 goal, with 35 days remaining. Rolling Square is a repeat Kickstarter creator with 10 campaigns completed, 15+ successful crowdfunding campaigns across platforms, and 2.2 million products sold worldwide. This is not a first attempt — it is a precision-engineered product from a Swiss team that has been doing this for years.

Is the Supertiny 100W Charger Worth Backing?
If you travel with a laptop and want to cut charger weight and bulk to near zero, yes. The Supertiny delivers laptop-grade power at earbuds-grade size. Rolling Square has the track record. At ~$47 Early Bird, this is the best price you will see for the world's smallest 100W GaN charger.
What Is the Supertiny 100W Charger?
The Supertiny is a single-port 100W GaN USB-C charger engineered by Rolling Square — a Swiss tech company known for their inCharge cables and AirCard products. It uses Gallium Nitride (GaN) technology to deliver 100W of output power in a physical footprint smaller than anything else in its class.
The US version weighs 100g and measures 52.1mm when closed (68.5mm with the foldable plug extended). The EU version is 105g and the UK version is 115g — all significantly lighter than competing 100W chargers on the market.
Rolling Square describes their community as "lifehackers" — people who want technology that solves real problems without adding friction. The Supertiny is the physical embodiment of that philosophy: maximum power, minimum presence.
What Problem Does the Supertiny 100W Charger Solve?
Laptop chargers are the last bulky item that most people carry every day. Phones got smaller. Earbuds got smaller. Cables got shorter. But the power brick sitting in your bag has stayed roughly the same size for a decade.
The Supertiny eliminates that friction. At 100g and the footprint of an earbud case, it charges a MacBook Pro, an iPhone, a Samsung Galaxy, or most USB-C laptops at full speed — without the bulk that makes carrying a charger feel like a compromise.
Supertiny 100W Charger on Kickstarter: Key Features and Design
World's Smallest 100W GaN Charger
The core claim is verifiable: the Supertiny is 65% smaller than Apple's 96W charger and lighter than any comparable 100W charger currently available. The engineering required to achieve this at 100W output is non-trivial — GaN technology alone does not make a charger this small. Rolling Square has redesigned the internal component layout and transformer alignment to extract every millimeter of space.
The result: a charger that fits in the same pocket as your AirPods case.
GaN Technology and Heat Management
GaN (Gallium Nitride) technology replaces traditional silicon in the power conversion stage. It produces less heat per watt of output, which is what enables the compact form factor. But Rolling Square goes further — the ribbed side design of the Supertiny prevents full contact with your fingertips, reducing the felt temperature by an average of 10°C compared to a flat-surface charger.
The internal redesign includes optimized heat conduction silicon and thermal sheets that manage heat dissipation even during sustained high-wattage charging sessions.
Universal Device Compatibility
The Supertiny 100W charges any USB-C device:
Laptops: MacBook Pro, MacBook Air, Dell XPS, ThinkPad, HP, Surface, Chromebook, and most USB-C Windows laptops (larger laptops may charge at slightly reduced speed)
Smartphones: iPhone, Samsung Galaxy, Google Pixel, Oppo, Xiaomi, and all major USB-C phones
Tablets: iPad Pro, Samsung Tab, and other USB-C tablets
Other: AirPods, Apple Watch, smartwatches, earbuds, and some e-bikes via USB-C
It supports Power Delivery (PD) and PPS protocols for maximum compatibility and fast charging speed across devices.
Three Regional Versions
The Supertiny is available in US (foldable plug), EU, and UK versions — each optimized for their regional plug format. The US version uses a foldable plug that makes it even more compact when not in use. The plugs are fixed — not interchangeable — a deliberate engineering choice to maximize compactness and eliminate mechanical wear from swappable parts.
The input accepts 100–240V at 50/60Hz, making all three versions globally compatible with a travel adapter.
Add-On: inCharge Life 2-in-1 Cable
Rolling Square offers the inCharge Life 2-in-1 as an add-on ($29) — a modular USB-C cable that charges two devices simultaneously from a single power source. It delivers up to 100W total, intelligently shared between devices. It comes with a lifetime replacement guarantee: cut the cable, send a video, get a new one. No returns, no forms.
Add-On: Tech Pouch
A compact water-resistant pouch ($29) designed to carry the Supertiny, inCharge cables, and small accessories in a single organized unit. Built with water-resistant coated ripstop exterior and waterproof ripstop interior. Six soft lycra pockets. Converts to a crossbody strap for standalone carry.

Worldwide shipping available. Plug selection (US/EU/UK) and shipping details confirmed via Backer Tools after the campaign. Early Bird tiers are running low — the 1× Supertiny Early Bird has only 22 units remaining at time of writing.
Add-ons: inCharge Life 2-in-1 cable ($29), Tech Pouch ($29), additional Supertiny ($47).
Cost framing: At ~$47 Early Bird, the Supertiny undercuts most premium 100W chargers while being significantly smaller and lighter than any of them. Anker's 100W GaN chargers start at $50+ and are 20–40% heavier. For the smallest, lightest 100W charger available, the early backer price is hard to argue with.
Supertiny 100W Charger vs the Competition
Supertiny vs Anker 100W GaN Charger
Anker is the benchmark for compact GaN chargers. Their 100W offerings are well-reviewed and reliable — but they are heavier (120g+ for most models) and larger than the Supertiny. The Anker advantage is multiple ports on some models. The Supertiny wins on size and weight if single-port is sufficient for your workflow.
Supertiny vs Baseus Picogo and Similar Compact Chargers
The compact GaN charger market has filled with competitors like Baseus Picogo. Most top out at 65W or 67W for truly miniaturized designs. The Supertiny is the only charger in the earbud-sized footprint category that reaches 100W — a meaningful difference for MacBook Pro and larger laptop users who need full-speed charging.
Supertiny vs Apple's 96W Charger
Apple's 96W charger is the reference point Rolling Square explicitly uses. The Supertiny is 65% smaller and charges faster (100W vs 96W) with broader device compatibility. The Apple charger is fixed at a high price and designed exclusively for Apple devices at full efficiency. The Supertiny charges everything.
Risks and Considerations
Rolling Square has completed 10 Kickstarter campaigns and 15+ crowdfunding campaigns across platforms, with 2.2 million products sold worldwide. Their track record is among the strongest of any creator on the platform.
The specific risks are minimal and standard: safety certifications are listed as in progress at campaign launch. International certifications (FCC, CE equivalents) are expected before shipping in July 2026.
The fixed plug design means buyers need to select the correct regional version at pledge time — there is no swapping later. Australian backers should note no AU plug is currently available.
Should You Back the Supertiny 100W Charger on Kickstarter?
Bulky chargers are a solved problem — or they should be. The Supertiny proves that 100W of laptop-grade power fits in the same space as an earbud case, weighs less than a baseball, and runs cooler than standard flat-surface designs.
Rolling Square has delivered 2.2 million products. They know how to ship. The Supertiny is the smallest 100W GaN charger ever made — and at ~$47 Early Bird, it is the best price this product will ever be.
If you travel with a laptop, this is a straightforward upgrade. Smaller, lighter, and powerful enough to handle everything in your bag.
