HyperJuice Next 5K Passes 115 Safety Tests With Semi-Solid-State Battery Tech

HyperJuice has completed more than 115 independent safety tests for its Next 5K Qi2 Solid-State Power Bank, according to reporting by 9to5Mac. The accessory maker states that the testing was conducted to ensure consistent and safe operation for users who rely on portable charging solutions for their mobile devices.

The power bank utilizes next-generation semi-solid-state battery technology, which 9to5Mac notes provides enhanced safety features and thermal stability. The manufacturer claims the build is designed to withstand everyday drops, bumps, and exposure to extreme temperatures without swelling. This design aims to address common issues with traditional battery packs that can overheat or degrade under stress.

Product Specifications and Features

The Next 5K offers a 5,000mAh capacity, which is compliant with airline carry-on regulations. According to 9to5Mac, the device includes a bonus USB-C port that allows users to charge two devices simultaneously. One device can charge wirelessly via the main MagSafe pad, while the second can charge using the wired USB-C connection.

The product is currently available at a discounted price of $40, down from the regular price of $50, for 9to5Mac readers using a specific checkout code. This pricing represents the lowest tracked price for the accessory to date. The device supports Qi2 wireless charging standards, ensuring compatibility with modern smartphones that utilize this protocol for efficient power transfer.

Market Context and Compatibility

While 9to5Mac lists the HyperJuice Next 5K among accessories for the iPhone 18 Pro, the source material does not explicitly state that the power bank is built specifically for that model. It is described generally as a Qi2 semi-solid-state solution for everyday portable charging. Users should verify compatibility with their specific device before purchasing.

In a related development, accessory maker BMX released a custom-fit 5,000mAh power bank for the upcoming iPhone Duo in October 2026, as Threat Times reported on 2026-10-19. That product was designed to address fitment issues with standard accessories. The HyperJuice product, however, focuses on battery chemistry safety rather than specific device fitment.

What should you do?

Consumers interested in solid-state battery technology should review the official specifications provided by HyperJuice to confirm compatibility with their current devices. Users should monitor for any additional safety certifications or updates from the manufacturer regarding the long-term performance of the semi-solid-state cells.

What to do and how to stay safe: HyperJuice

• Verify that your device supports Qi2 wireless charging before purchasing a Qi2-certified power bank.
• Check airline regulations for battery capacity limits if you plan to travel with the power bank.
• Monitor manufacturer websites for firmware updates or safety recalls related to portable chargers.
• Compare thermal performance data if available to assess suitability for high-drain applications.
