The included solar panel sweetens the deal, but at 45 watts it's kind of at the lower end of what would be really useful for this size power station. For example, If you pulled a constant 40 watts with this panel, it would still take about 8 plus hours or 2 full days of sun to charge from zero to full. A single 100 watt panel would've really been nice and could give you a full charge within a single day of good sunlight. The specs says it can handle up to 110 of solar so a 100 watt panel would've been a perfect match. The price point is still good for what you get.

Yeah, but 100 watt is a lot bigger. Its easy to hang these up somewhere.

For instance, say i have a 12v cooler or fridge in my truck. Plug this in, run this out the back window and lay it on the tonneau cover. If the fridge is full of cold stuff or precooled it will honestly probably run it pretty much forever if it catches 6 or 7 hours of near full capacity light.

Does anyone know if this solar panel can also be used to charge the EcoFlow River 3 Plus Wireless Boost Combo?

Good luck running your fridge like that. I can assure you It's not going work out like you think it is. PV power collection for a solar panel is typically calculated using between 3 to 5 peak sun hours per day, with 4 being a good average. Your not going to get 6 to 7 hrs. of charging per day from the sun. You're just not. You get partial charging outside of peak hours but the industry usually settles in around a 4 hr average. If you look at 200W solar panel ads, they will typically advertise that it can collect 800wH per day, which is based on 4 hrs. Also keep in mind, they are trying to sell you panels so even that is an inflated & over rated (in perfect laboratory conditions number, not real world) number compared to what you're going to get in the real world. Get that 6 to 7 hrs of full capacity sunlight figure out of your head. It's just not going to happen. A little research goes a long way my friend. Only 1 to 2% of the entire country in only the most sunny & hottest desert climates receive as much as 6 hours of sun per day, with 0% of the country getting 7. (see the included diagram below)The overwhelming majority sits between 4.5 and 3.5. Again, 4 being a good average to work off of. Lastly that 45W panel realistically collects maybe somewhere between 25 to 35 watts not 45. Between all of this, your calculations are most likely around 2 to 3 full days or possibly more off your 1 day goal.

I'm not exactly sure how you are mathing your "it'll honestly probably run pretty much forever if it catches 6 or 7 hours of full capacity sunlight" because that's not even close to a realistic calculation my man. Lets do the real math and crunch the numbers. Let's do an absolute best possible scenario situation, and even though it's not going to happen, lets just say you manage to collect an average of 40 watts for 6 hours per day with this 45 watt panel laying flat on your truck. If you can somehow manage to get 6 hrs of solid unbroken sunlight and really get a consistent 40 watts from this panel, your still only maxing out at just 240wH per day. Divide that by the hours in a day, 24,.. and that breaks down to just 10wH per hr you can afford to use before you're burning through your power faster than you can collect it. What does all this mean? It means there's absolutely no possible way you can slice it, to where this works like you think it would. Not even remotely close.

If size and overall footprint isn't a concern, I'd highly recommend spending 50% more money and getting something thats more than 300% the rated capacity (1000Wh vs 300Wh) and over 100% more solar panel wattage (100 vs 45watts) of this and actually has a real 1200watt AC inverter to run real household appliances. Of course if you need something small, and just need to charge things via USB, then this Ecoflow might be better suited for you, but outside of physical size, The OUPES Exodus 1200 with 100watt solar panel for $300 deal demolishes this deal in ever other possible metric and usefulness.
