Ports, Connections & Solar Cable Compatibility

One of the biggest frustrations I had while researching the Swarey 300W Portable Power Station was working out exactly how the solar input works. Many listings gloss over this detail, yet it’s one of the most important things to understand if you’re planning to charge via solar. Thankfully, once the unit arrived, the setup turned out to be refreshingly straightforward.

Output Ports – What You Can Power

The Swarey 300W provides a well-rounded selection of outputs for everyday use:

AC Socket (300W, 600W surge) – Suitable for laptops, monitors, routers, small TVs, desk fans and other low-power mains devices.
USB-A Ports – Ideal for phones, tablets, cameras, power banks and accessories.
USB-C Port (18W) – Handy for modern devices, although slower than 60W+ fast-charging laptops.
12V DC Output – Useful for car-style accessories such as portable coolers, inflators, and other 12V devices.

This mix makes the Swarey a solid choice for offices, camping, fishing trips and general backup power.

Input Ports – Charging the Power Station

Charging the Swarey is simple and flexible:

DC Input Port (12–30V) – Used for mains charging, car charging, and solar charging.
Mains Charging Cable – Included in the box.
12V Car Charging Cable – Also included.

Solar Charging – The Important Bit

This is where the Swarey really shines for budget-conscious buyers.

The power station includes an 8mm solar input adapter cable, and on the other end of that cable is a standard MC4 connector. MC4 is the most common connector used on solar panels, including the vast majority of 100W portable panels.

Swarey S160 Solar Charging Cable with MC4 Connector

✅ No proprietary connectors
✅ No brand-locked solar panels required
✅ Works with standard MC4 solar outputs

This is a major advantage over brands like Jackery, which use proprietary solar connectors. With Jackery, you’re often pushed toward buying their own branded solar panels or additional adapters, which significantly increases the total cost of ownership.

With the Swarey, if you already own a solar panel — or are buying a standard MC4-equipped panel — you’re good to go straight out of the box.

What Solar Panels Will Work?

As long as your panel:

Uses MC4 connectors
Falls within the supported voltage range
Is rated up to around 100W

…it will be compatible with the Swarey 300W using the included MC4-to-8mm cable.

My own 100W solar panel is currently on the way, and I’ll be publishing a follow-up article with real-world solar charging results once I’ve tested it properly.

Why This Matters

Search terms like “what solar cable does the Swarey 300W use?” and “can I use any solar panel with Swarey power stations?” come up again and again — and for good reason. Solar compatibility is often poorly explained.

In short: the Swarey keeps things simple, affordable, and compatible with standard solar gear — exactly what you want from a budget-friendly portable power station.

Solar Charging Expectations

The Swarey 300W features a built-in MPPT controller, which helps it charge efficiently via solar panels. I have a 100W solar panel arriving shortly for a deep-dive test.
