## Product: Rolling Square Supertiny Charger
**Brand:** Rolling Square

## Pros
- Impressively small and ultra-compact at only 1.7 inches long, making it one of the tiniest 65W USB-C chargers on the US market as of late 2025.
- Uses efficient GaN technology to deliver consistent, powerful 65W fast charging suitable for phones, tablets, laptops, and other USB-C devices.
- Outperforms many previous 65W chargers and even some well-known competitors like the Anker Nano, offering more power in a smaller package.
- Excellent for charging high-demand devices such as MacBook M1 Max Pro, sustaining around 60-100W power output even under heavy workloads like video editing or intensive CPU tasks.
- Runs cool overall without overheating in typical use, making it reliable for daily travel needs.
- Foldable US plug and lightweight design make it incredibly travel-friendly and easy to carry anywhere.
- Versatile enough to replace multiple chargers you might carry for various USB-C devices throughout the day.
- Maintains good battery life for laptops running demanding apps, preserving about 80% charge after long rendering sessions.
- High build quality praised by users, reflecting a premium feel and durability.

## Cons
- While compact, it can run significantly hotter compared to slightly larger chargers when delivering full power for extended periods, becoming too hot to comfortably touch.
- Not ideal for prolonged heavy use at home or long work sessions due to heat buildup under continuous max load, especially when paired with heavy accessories like Thunderbolt 3 docks.
- Slightly larger than some ultra-miniature chargers on the market, though still very manageable for travel.
- Users uncertain about future-proofing with devices needing more than 65W charging as tech advances.

## Bottom Line

The Rolling Square Supertiny 65W USB-C GaN Wall Charger is a powerhouse in a tiny package, perfect for travelers and users wanting a compact yet reliable fast charger that handles demanding laptops and USB-C devices with ease. However, if you plan to push it hard for long hours in a home or office setting, heat could be a concern. If you prioritize fanless charging with less heat under heavy load, you might want to consider a slightly larger charger, but for on-the-go power without bulk, this is tough to beat.
