The Supertiny – 100W power, world’s smallest size Kickstarter Review

Intro

Welcome to KickstartNew! Today we’re looking at a project that focuses on something every modern user needs — power. The Rolling Square 100W GaN USB-C charger aims to deliver high-speed charging in an ultra-compact form, making it one of the smallest chargers in its class. Designed for travelers, remote workers, and minimalists, this charger promises to reduce bulk without sacrificing performance.

Why should I back this project?

1. Ultra-Compact Design: The standout feature is its extremely small size, making it easy to carry in your pocket or bag without adding noticeable weight.
2. Powerful 100W Output: Despite its size, it can charge laptops, tablets, and smartphones efficiently, reducing the need to carry multiple chargers.
3. GaN Technology Advantage: Gallium Nitride technology improves efficiency, reduces heat, and enables smaller hardware compared to traditional chargers.
4. Multi-Device Convenience: With USB-C support, it works across a wide range of modern devices, making it a versatile daily accessory.
5. Travel-Friendly Solution: Its compact footprint makes it ideal for frequent travelers who want a clean and minimal charging setup.

What’s the potential drawbacks you should consider when you back it?

1. Heat Management Concerns: High power in a very small form factor may lead to heat buildup under heavy usage.
2. Limited Ports: Depending on the configuration, you may still need additional chargers if you want to power multiple devices simultaneously.
3. Premium Pricing: Compact GaN chargers often come at a higher price compared to standard alternatives.
4. Diminishing Returns: If you already own a good GaN charger, the size reduction alone may not justify upgrading.

The reliability of the project

1. Established Brand: Rolling Square has experience launching consumer tech products, which adds credibility to their execution.
2. Proven Technology: GaN charging is already widely adopted, reducing the technical risk compared to experimental hardware.
3. Real-World Use Case: The product solves a clear and common problem — bulky chargers — which increases its practicality.
4. Manufacturing Risk Still Exists: As with any hardware campaign, production timelines and quality control remain factors to watch.

Conclusion

The Rolling Square 100W GaN charger is a strong example of incremental innovation done right. It doesn’t reinvent charging but refines it — making it smaller, more portable, and more convenient for everyday use. For users who travel frequently or value minimal setups, this charger can significantly simplify their tech carry.

That said, it’s not a must-have for everyone. If you already own a reliable fast charger, the upgrade may feel marginal unless portability is your top priority. Overall, it’s a practical, well-positioned product with clear value for the right audience.
