SOLUPUP Solar Panels 30W Portable Foldable Solar Charger with 5V USB-A and USB-C Fast Charging Compatible with iPhone, iPad, Samsung, Power Banks, IPX5 Waterproof Perfect for Camping, Hiking, Outdoor

Edit: I left this set up in a precarious location. Long story short, I came back to check on it and found it floating in the lake. I took it out and it was still attempting to charge my devices! I am happy to report it is fairly waterproof! I love this solar set up. So far I've had opportunities to use it in varrying conditions and it hasn't failed me yet. I purchased this to replace a solar/battery bank system. It's worth every penny and it's about the same size as a clipboard. Super easy to set up and use. I've used it with both devices and battery banks. It's a very fast charge and I've even been able to charge on a cloudy day. It's worked well during the summer time without overheating as long as you keep the panels away from the device being charged. I had originally hung out from my tent in full sun and used the pouch to hold my device and came back to it almost cooked. If you set it up with it's stand though the problem is entirely mitigated.

I bought this solar panel because we plan to visit Hawaii during hurricane season, if a hurricane decides to visit Hawaii it may create power outages as hurricane LaLa did. I drained a 5000 mAh battery and hook it up to the solar panel on a warm sunny day, it took three hours to charge it. The solar panel is of excellent quality and cost less that half of other that are comparable.

Well built and charges my cellphone, but you'll be lucky to get 10w in full sunlight. It's much too heavy to be useful to backpackers and weights more than a 20,000mAh battery pack.

Out of the box this solar charger was a hit from the git=go. Easy setup and in bright sunshine it began producing the voltage needed to charge my mobile phone, two of my small, portable power banks for backup and my Amazon Kindle Fire tablet. It does get a bit warm when receiving sunshine so be careful handling. I suggest keeping the item being charged in the shade for cooling. The long cord supplied with the solar charger has enough length so that the charger is in total sunlight and the item being charged can be in shade.

This is an emergency must! It is light and compact. It will charge your phone and laptop without any hesitation.

Perfect for solar charging your cellphone. I use it my car @ work, just unfold it plug in my usb charging cord lay it on the dash in the sun & instantly my phone recognizes it & starts charging. It depends on the intensity of the sun of course but it really does work. It’s well made & doesn’t feel like cheap junk when you’re using it. I liked it so much that I bought another one. IMHO a great item!

Nice little compact size. Lightweight. Charges like you would expect from a 30W.

This charger is great. Only used it on one backpack trip. Hung it on the back of my pack and ran the cord to my phone. I was walking in trees a lot and walking towards the sun a lot and still gained 25% on a three hour hike. I think for one person a two panel would be plenty, mine is three.
