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.
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.
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.
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.
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.
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.
