Hey everyone! I'm new to solar power and electronics, so I'm looking for some guidance. I want to create a simple solar setup that's portable, ideally under 2 feet by 2 feet, so I can use it to boost my truck battery when I'm off the grid. My plan is to let the panel charge my truck battery during the day while I can charge my devices at night using the truck. Additionally, I want this same solar panel to power a small fan in my shed when I'm home. I'm overwhelmed by all the conflicting info out there and don't want to spend a fortune—especially since I just need to occasionally start my truck and keep the battery topped up instead of investing hundreds in complicated gear. Any suggestions for basic and budget-friendly solutions?

Just to give you a heads up, a solar panel that's 2x2 ft might take a week of full sun to charge a typical truck battery from empty. Are you set on that size?
You might want to check out the EcoFlow River 3 Plus and pair it with a small solar panel that fits your needs. It’s pretty versatile! Just keep in mind that it costs around $285, which is a bit more than just starting your truck for 15 minutes, but it's a solid option.
From what you've described, it sounds like your truck battery is draining because you’re charging devices, right? Consider grabbing a cheap power bank along with a USB solar panel. I found a solar panel on Amazon that's fairly affordable; it could help charge your power banks without putting stress on your truck battery. Just a thought!
That is a bit pricey! I was hoping to find something cheaper that just does the basics.
