E-Ink technology has come a long way, and Reink Case C2 pushes its limits by offering the largest E-Ink display ever built into an iPhone case. This 4-color E-Ink case allows users to customize their phone’s back with personalized designs, widgets, or text—without draining battery life. But is it a game-changer, or just a stylish gimmick? Let’s dive into the details.
Design & Build Quality: A Premium, Minimalist Look
The Reink Case C2 is crafted from high-quality matte materials, providing a smooth, fingerprint-resistant texture that feels great in the hand. It’s available for various iPhone models, fitting snugly while maintaining a lightweight and stylish aesthetic.
The main highlight? The largest E-Ink screen ever integrated into an iPhone case—taking up a significant portion of the back panel. The 4-color E-Ink technology (Black, White, Red, and Yellow) makes it more vibrant and customizable than previous models that only supported 3 colors.
✔️ Matte finish feels premium
✔️ Scratch-resistant & lightweight
✔️ Fits perfectly without adding bulk
Display: E-Ink, But Bigger & Better Than Ever
Key Display Features:
• Size: The largest E-Ink display on any phone case to date
• Colors: Black, White, Red, Yellow (upgraded from 3-color versions)
• Update Method: NFC-based refresh (no battery required)
• Refresh Speed: ~3 seconds per update
✔️ Great for always-visible notes and widgets
✔️ No power consumption for static images
❌ Updates require manual NFC refresh
Functionality: How It Works & What You Can Do With It
Using the Reink App, you can customize the case’s display with:
• Custom images & wallpapers
• QR codes (for quick sharing or payments)
• Reminders, to-do lists, and notes
• Weather, calendar, and battery widgets
How does it update?
The case doesn’t require a battery—instead, it refreshes the screen via NFC. Simply tap your phone to the case, and the E-Ink display updates within 3-5 seconds.
✔️ No charging required
✔️ Completely wireless
❌ No real-time updates (must refresh manually)
Wireless Charging & Protection
One of the standout features of the Reink Case C2 is MagSafe compatibility, meaning you can wirelessly charge your phone while using the case—something many battery-powered E-Ink cases struggle with.
Additionally, it includes:
• Raised camera edges for lens protection
• Shock-resistant material to absorb drops
• Soft inner lining to prevent scratches
✔️ Wireless charging works seamlessly
✔️ Lightweight, protective, and stylish
❌ Not as rugged as heavy-duty cases
Battery Life: No Power Needed!
Unlike most tech-based accessories, the Reink Case C2 doesn’t have a battery. Since E-Ink only uses energy when changing images, this means:
• Zero power drain on your iPhone
• No need to charge the case itself
• Always-on display without battery concerns
✔️ Eco-friendly & power-efficient
✔️ No cables or extra charging hassle
Pricing & Availability
The Reink Case C2 is available for $79.90, making it one of the most premium and feature-rich E-Ink cases on the market. It’s currently compatible with iPhone 14 & 15 models, with more options expected in future updates.
