RIIEYOCA Dual Port USB A & USB C 5V to 12V Step Up Converter Cable (12W, 1.5m)
Product description
What it is and what it’s for
The RIIEYOCA dual port USB A & USB C to 12V DC step-up converter is a compact, cable‑based power solution designed to deliver a stable 12V output from a 5V source. With a 5.5x2.1mm connector and a maximum of 12W (about 1A), it targets low‑power devices such as routers, modems and similar compact network gear. The integrated switch and LED indicator give you quick, tactile control and immediate feedback on whether the 12V output is active. If you’re looking to keep a home network running during power outages or while you’re on the move, this cable offers a straightforward way to convert portable 5V power into a usable 12V supply.
How it works in practice
You can draw power from a variety of 5V sources, thanks to dual inputs: USB‑A and USB‑C. The device then steps up to a 12V output with a standard 5.5×2.1mm plug, which is common for small network devices. The 1.5‑metre length adds flexibility when you’re wiring devices across a desk or a small room, and the design emphasises durability with thick copper conductors and a robust PVC jacket. Before buying, it’s important to confirm the target device’s power draw to stay within the 12W/1A limit.
What stands out on paper
On the surface, the standout features are the two input options, a dedicated on/off switch, and a dual‑colour LED that clearly communicates status: red means 12V off, green means regular 12V power. This lets you avoid constant plugging and unplugging and helps protect ports by reducing repeated use. The protection suite covers overcurrent, overvoltage, short circuits and overheating, offering a sensible safety net for everyday use in a home office or when travelling.
Considerations and limitations
It isn’t a universal power solution for high‑powered devices. If your 12V device draws more than 1A, or if it requires a more precise power profile (for example, devices with strict startup surges), this cable may not be the best fit. The spec explicitly notes suitability for devices with power consumption ≤12W, exceeding that will either reduce performance or risk protection triggers. Also, as with any step‑up solution, efficiency and heat generation can vary with load and source quality. If you prioritise quiet operation or absolute efficiency for long sessions, you might want to compare with dedicated, purpose‑built power supplies.
Who it’s for
This cable makes sense if you want a simple, portable way to power small network gear from USB sources: a laptop, power bank, or USB charger can become the source, with the network device staying powered during a brief outage or while you relocate equipment. It’s particularly practical for light home offices, temporary setups, or scenarios where you don’t want to rely on mains sockets in awkward spots.
Who it isn’t for
If you expect to run a high‑drain device, or you want marginal gains in efficiency and noise, look elsewhere. It’s not designed for high‑power appliances or equipment that needs precise, constant 12V regulation beyond 1A. In environments where power quality matters (very long uptime, sensitive electronics), a dedicated 12V power supply with regulated output may be more appropriate.
What to check before buying
- Verify your device’s power draw is at or below 12W (1A) and that it uses a 5.5×2.1mm interface.
- Confirm source capability: a reliable 5V USB port from a power bank, wall charger, or laptop will drive the converter, but performance depends on the source quality.
- Be aware of the cable length (1.5m) and whether it fits your setup without creating tension on connectors.
- Consider the safety features: overcurrent, overvoltage, short circuit and overheating protections are included, but no system is perfect—ensure you monitor the first uses for any unexpected behaviour.
Practical use case
Imagine you’re working from a couch with a portable power bank. You connect the USB power bank to the dual input, flip the switch, and green indicates the router receives 12V. The network stays online while you stretch a long HDMI/ethernet cable to a nearby modem and you don’t have to hunt for a mains outlet mid‑setup. It’s not a miracle cure for every power issue, but for light, temporary needs it can smooth out interruptions.

FAQ
- Will this work with any 12V device? It works for devices with power consumption up to 12W (1A) and a 12V interface, higher power devices may not run reliably.
- Do I need both USB inputs to function? No, you can use either USB‑A or USB‑C as the 5V source.
- Is the switch always on when connected? The LED indicates power status, you can turn power on or off with the switch.
Is it worth it?
If your use case involves keeping essential low‑power network gear running from USB power sources and you prioritise simplicity and portability, it offers a straightforward solution. It’s a practical option for occasional outages or temporary setups, but it isn’t the best choice if you need high efficiency, very steady regulation, or power for higher‑draw devices. It may be a sensible addition to a travel or home office kit, provided you stay within its stated limits.
