Rockpals
reviews and complaints

Yo, so I copped these 100w Rockpals panels to juice up my Delta Ecoflow 1300w solar generator and I gotta say, I'm pretty stoked about it. When the sun is shining bright, these bad boys are pumping out 80 to 90 watts of power! Some folks even reported getting up to 94 watts. Now, I also got the Ecoflow 110w panel and I gotta admit, it's a bit better quality but it also costs twice as much. So, for the price, these Rockpals joints are definitely one of the best foldable panels out there in terms of bang for your buck.

My only gripe is that they don't come with an integrated stand to make positioning them easier. But hey, I can figure out a workaround for that myself. Overall, I'm pretty happy with my purchase and would definitely recommend these panels to anyone looking for a solid, affordable option.

Why choose the Rockpals 300 over the more popular 250? Well, let me tell you, the 300 may not have a ton more capacity, but it has some features that make it worth the extra dough. First off, the charger is built-in, so you don't have to worry about keeping up with a power brick - just plug in a three-prong AC power cord and you're good to go. Second, it has a built-in 12-volt cigarette lighter jack at 8 amps, so no need for an additional dongle. And third, any output can be switched off or on, which means that the inverter is off when not in use, saving you some power.

Now, let's be real here - these small power banks aren't going to power anything too crazy. You're not going to be running heaters or refrigerators off of them. But they're great for low voltage devices like CPAP machines or 12-volt lighting. I personally use mine for lighting, and it works great with repurposed lamps and 12-volt A19-type bulbs from Amazon.

During testing, I've been getting around 244 Wh out of both of my Rockpals 300s, which is close to an 85% discharge efficiency. That's better than I expected, and it seems like discharge efficiency can vary depending on a lot of factors. But overall, I'm happy with the performance.

Now, I did snag these bad boys on sale for $270 each, so that definitely sweetened the deal. But even at full price, I think the Rockpals 300 is a solid choice if you have realistic expectations for what it can power. Just make sure to evaluate your specific needs before investing in any power bank.
