This solar panel kit is like the Hulk of portable chargers. It's bigger and heavier than I expected, and unfolding it feels like trying to tame a wild beast. The supports don't have a cross brace, so the panels bow like they're auditioning for a yoga class. Even in a windless area, it's a challenge to keep them from folding back in and collapsing. And despite coming with a DC charging adapter cable, it's missing a charging regulator/controller, so it's like having a fancy car with no engine. For the price, I expected better. I might as well have bought two kits with charge controllers and saved some cash. I'm returning this beast and sticking to a different brand.

Packaging is usually not something I mention, but when you're dealing with a behemoth like this, it's a valid concern. Thankfully, it arrived double-boxed with thick card boxing and foam pieces, so it survived the journey intact. As for the product itself, it's well-made and surprisingly light for its size. The fold-out supports are handy, but I wish they had some cross bracing for extra stability. Maybe I'm overthinking it, but I don't want my solar panels doing yoga poses. I bought this for camping trips, and while it takes up some space, its flat design makes it easy to find a spot. Setting it up is a breeze, and the slight flex in the panels hasn't caused any issues. It's like having a gentle giant by my side.

These solar panels come in a cleverly designed pack that makes them highly portable, despite their weight. They unfold easily and can be positioned to catch the best sun rays. While they may seem like they'll collapse under their own weight, they surprisingly stay up securely and can be set up and packed away without a fuss. The pocket for storing cables is a nice touch, adding just a little extra bulk. They fit in the car boot with plenty of room to spare, even with all our luggage. But let's not ignore the elephant in the room – they are heavy! However, they charge up well and are great for camping, as long as you don't mind lugging around some bulky panels. Just be careful if it starts raining, as the material design might not hold up. Overall, they did the job of charging our portable power station, making them a good option for occasional use.
