Overview

The YIPIN HEXHA DC 12V/24V~5V USB C 5A 25W Step-Down Converter is a compact waterproof buck converter designed to step down 8V–32V DC input to a stable 5V output via a USB Type-C port. It delivers up to 5A (25W), making it suitable for powering Raspberry Pi 4, dash cams, motorcycle electronics, and other 5V devices in automotive or industrial environments. Sold as a 2-pack, this module features a sealed back-case design that protects against moisture and vibration. It's an affordable solution for anyone who needs to tap into a 12V or 24V battery system without buying a bulky AC adapter.

Connectivity & Compatibility

Input is via bare red/black DC wires — connect to a 12V or 24V power source (8V–32V range). Output is through a USB Type-C port that provides 5V at up to 5A. It works with any device that accepts 5V USB power: Raspberry Pi 4, single-board computers, dash cams, smartphones, and more. Important: the Type-C port is power-only — no data transfer or PD negotiation. Polarity must be observed (red = positive, black = negative); reverse connection will permanently damage the module.

Product Info

Released around 2024, this 2-pack is available on Japan for roughly ¥2,500–¥4,000. Warranty follows 's standard return policy. Market positioning is entry-to-mid-range: it lacks advanced protection features found in premium DC-DC converters, but offers excellent value for simple 5V power expansion in vehicles or DIY projects.

Best Use Cases

Raspberry Pi users: Ideal for powering a Pi 4 in a car or off-grid setup directly from a 12V/24V battery. Not suitable for Pi 5 which may exceed 5A peak draw. Motorcycle & vehicle owners: Powers dash cams, GPS trackers, or LED controllers from the bike's electrical system. The waterproof housing helps in exposed locations, though full submersion is not recommended. * Electronics hobbyists: Two units in one pack let you keep one for prototyping and one for permanent installation. Wide input voltage range also works with solar panels or battery banks.

Things to Consider

Double-check polarity before connecting — reversing the wires will destroy the converter instantly. For continuous high-current use, derate to about 4A to avoid overheating. The USB-C port is power-only, so don't expect data sync or fast-charge negotiation. If your device requires more than 5V (e.g., USB-C PD laptops), this module won't work. ## FAQ
Q: Can I use this with a Raspberry Pi 4? A: Yes. The Pi 4 needs 5V/3A, which this converter supplies easily. Any standard USB-C power cable will work. Q: Is it safe to connect directly to a car battery? A: Yes, for 12V cars. The 8V–32V input range handles engine-start voltage spikes. Also works with 24V trucks. Q: How waterproof is it? A: The module has a sealed back case, but no official IP rating. It can handle rain splashes but not immersion or pressure washing.
