Review: Have Recommended to Friends and Family - I recently purchased the SunJack 40 Watt Folding Portable Solar Panel for a week-long camping trip, and it turned out to be a solid investment. Here’s what I found after using it on the go: Pros: 1. Impressive Charging Power: For its size, this thing delivers serious power. On sunny days, I could fully charge my smartphone in under two hours, and it handled my tablet and small power bank without breaking a sweat. The 40 watts really do make a difference for larger or multiple devices. 2. Compact and Portable: I love how it folds up. When folded, it’s about the size of a laptop, so it was easy to slip into my backpack. It’s a bit heavier than I expected, but not so much that it’s a hassle to carry around. 3. Rugged Build: This panel feels like it was made for the outdoors. The outer material is durable and held up well to dirt, light rain, and being tossed around. It seems like it’ll last for quite a few more trips. 4. When paired with a battery pack or solar generator, we had ample charge to power our electronics throughout the night until we could charge again the following day. Cons: 1. Weight: While it’s not unbearable, it’s definitely not ultra-light either. For short trips, it’s fine, but if you’re an ultralight backpacker, you might find it a bit heavy for what it provides. 2. Requires Direct Sun: Like most solar panels, this one needs strong sunlight to work at its best. Partly cloudy days still work but noticeably reduce charging speed. It struggles indoors or in shaded areas, so you’re out of luck in forests or overcast conditions. 3. Efficiency: As with all solar panels, there is some wattage loss by the time it makes it to the device. In my limited testing so far, with direct sunlight and overall optimal conditions, I was seeing around a 33W input into my solar generator. Overall Impression: If you’re looking for a reliable, portable power solution for camping, emergencies, or outdoor work, the SunJack 40 Watt Folding Portable Solar Panel is a fantastic option. It’s powerful, durable, and convenient to carry if you don’t mind a bit of extra weight. Yes, it’s a bit of an investment, but the quality feels worth it. I’d highly recommend it to anyone who spends a lot of time off-grid!
Review: Everything's Great Except The Price - Feels very well built. Works great so far when tilted properly towards the sun. Good stand. A tad heavy. Survived rain so far. Folds good too. The fly in the ointment is the price. It's really too expensive compared to alternatives on the market.

### ⭐⭐⭐⭐⭐ Excellent product support
*by J***N on May 23, 2025*

Purchased the 40w version 7-8 months ago. It's heavy duty construction and design is worth the extra $$$ in my opinion. I wasn't going to write a review but then a week or so ago, it stopped working. Completely dead. I sent an email to Sunjack customer service and got a very fast reply. After a few diagnostic steps, he asked for my address and sent me a replacement. They stand behind their product. You can't say that for most of these companies today. Sunjack has my business from now on.
