SVBONY SV241 Review: A Simple, Affordable Power and USB Hub for Astrophotography

Introduction

Running an astrophotography rig often means juggling multiple power and data connections. A mini PC used for imaging control typically has limited USB ports and no power outputs, forcing you to rely on splitters and hubs that can be unreliable. The SVBONY SV241 aims to solve this by combining a 12V power distribution hub and a USB hub into one compact, affordable box.

This review looks at what the SV241 offers, how it performs in a real setup, and the trade-offs to consider before buying.

What Is the SVBONY SV241?

The SVBONY SV241 is a small box designed to aggregate power and data connections for an astrophotography rig. It provides a single point for connecting your camera, mini PC, dew heaters, and other accessories, reducing cable clutter and the need for multiple splitters.

It is positioned as a budget-friendly alternative to more expensive solutions like the Pegasus Astro Powerbox. While it lacks the advanced software control of those devices, it focuses on the core function of delivering reliable power and USB connectivity at a much lower price.

Ports and Power Outputs

The SV241 offers a practical set of connections. On one side, you have a 12V DC input for power and a USB 3 input for data. The box includes a USB 3 cable and a male-to-male DC cable, along with a cigar plug to DC cable.

On the other side, you get four DC outputs that provide up to 12V 10 amps, which is sufficient for most rigs. There are also two more DC outputs, bringing the total to six. Additionally, there are two USB outputs for 5V power, ideal for powering dew heaters on smaller telescopes, guide scopes, or camera lenses. These USB power outputs can deliver up to 5V 8 amps.

For data, the SV241 includes one USB 2 port, two USB 3.1 ports, and one USB Type-C port. This variety covers most modern cameras and accessories.

Mounting and Build

The SV241 has a 1/4-inch screw hole on the back, along with two small screws on the side. These are intended for mounting the box, possibly with a finder shoe. However, the box does not come with any mounting hardware, which is a notable drawback. You will need to find your own way to attach it to your telescope or mount, such as using Velcro straps.

The build quality is simple and functional, consistent with the brand’s reputation for practical, no-frills equipment. The included cardboard box is basic, containing just the essential cables and a manual.

Real-World Performance

In practice, the SV241 works as intended. It can power a mini PC and a camera simultaneously from its DC outputs, and the USB hub functions without issues. The 5V USB outputs are effective for powering a dew heater, keeping optics clear during imaging sessions.

One of the key benefits is that it solves the problem of limited USB ports on mini PCs. With the SV241, you no longer need USB-C to USB-A adapters or a separate powered USB hub. Everything connects through the single box.

The power outputs are always on, meaning there is no way to switch them off remotely. This means you will need to physically disconnect devices, like a dew heater, when not in use to avoid unnecessary power drain.

Things to Consider Before Buying

The SV241 is a non-controllable hub. You cannot turn individual power outputs on or off, nor can you adjust the power level. There is no ASCOM control, so you cannot manage the box from your PC. This is a significant limitation if you want automated control over your power distribution.

The lack of included mounting hardware is another consideration. You will need to source your own solution for attaching the box to your rig.

The included cables are minimal. You get one male-to-male DC cable and one cigar plug to DC cable. If you need more, you will have to purchase them separately.

Buying Advice

The SVBONY SV241 is a solid choice for astrophotographers who want a simple, reliable way to consolidate power and USB connections without spending a lot. It is particularly useful for those using a mini PC as their imaging controller.

If you need advanced features like ASCOM control, adjustable power outputs, or temperature and humidity sensors, you will need to look at more expensive options. However, for the price, the SV241 delivers excellent value for its core function.

Conclusion

The SVBONY SV241 is a straightforward, effective solution for managing power and data on an astrophotography rig. It works reliably, solves common connectivity problems, and is priced affordably. While it lacks advanced control features and mounting hardware, it does exactly what it is designed to do. For those looking for a budget-friendly way to simplify their setup, the SV241 is a worthwhile investment.
