[Upgraded] Foldable Solar Panels 50W Portable Solar Panel Charger 3 Output Ports (USB-A USB-C DC) Folding Solar Panel for Camping Hiking RV Outdoor Activities

I love this thing! I connected to a anker bank and it will run a box fan and charge phones all day. Which sounds silly but it’s a life saver on the side of the sporting fields and camping!

Rebuilding my campervan and didn’t want to mount a solar panel on the roof as before. I already have a battery isolator to charge my house battery while driving, but wanted some solar to top up while camping. I’ve only tried it once but it worked like a charm. In the somewhat low Virginia winter sun with clear skies my charge controller was showing it producing about 13.7 volts at over 4 amps. The design is rugged, and I love that it folds up so compactly and I can store it away easily. If you’re using it like me and will be connecting/disconnecting with MC4 connectors I strongly suggest using a tool designed for that purpose. It’s a little disappointing that they didn’t include a plastic tool for this purpose, but you can pick up a set for a few bucks here on Amazon. Would definitely buy again.

I bought this to keep my Anker 521 portable battery (256wh) topped off during an upcoming camping trip. It's built well and folds up small enough to toss in a backpack. The cable it comes with is a little short, but it has the end I needed for my battery and I'm sure I can find a longer cable if I need it.While it's rated for 50w, it seems manufacturers all the way from name-brands to ones like these rate them higher than you'll actually get in the real world. On my roof angled towards the sun on a clear day, I get between 30 and 35 watts into my Anker - perfect for my use case, as I'm only going to be using my battery during the night. If you need more than that, get the 100w version.Update: it performed pretty well, pictures attached. I definitely recommend getting an extension cable though.

One of my power stations has a max of 100 W. Bought this 120 to make sure that I max out input. Also, it was important to be portable and small as I am taking this camping and don’t want to carry around large panels. This is very packable and was putting out good numbers. I like the bag that it comes with. Seems to be a decent quality… I’ve seen sturdier panels but dollar for dollar and for it’s size... This is hard to beat. Was pumping out 90 to 100 W on a sunny day with imperfect angle. Also did not require any additional adapters to connect to my Anker.

I’m happy they remembered Senior Citizens , we are not strong like a young person , so a light weight solar panel is extremely important , especially in van life , cause space in a van is extremely limited , and this solar panel folds up smaller then the size of your car seat & weighs about the weight of a small rabbit , not to mention that it’s very efficient .I unfolded very easy and place it on top of my roof on my van , it’s very compact on top of my roof and extremely lightweight , and I also love the fact that I still have space on top of my van for two more solar panels , so thats exactly what I did , I purchased two additional wafer panels from EF at 100w each plus this small compact 120w solar panel that folds to the size of my front seat like a thin little book , now I have a total of 320w of solar panels , and now I can charge up my Delta 2 in a day . I prefer to put up my three solar panels and take them down at the end of the day , parked in a different location , cause I don’t want anyone of the locals to know I have power stations and solar panels inside my vehicle and compromise my safety . And one last thought , make sure you also purchase from Amazon a tool that disconnects your mc4 connectors unless you’re a strong person . In conclusion I highly recommend this small 120w lightweight folding solar panel to everyone.

30w PD USB-C output unreliable and highly disappointing. The main reason I bought this panel was the 30w PD capability. This is a huge benefit for me and the devices I need to charge. The build quality and power production have been what I expected, however the USB-C port on the panel is basically useless. I have tried to charge several power delivery capable devices unsuccessfully. The only device that will draw power from the USB-C port is my iPad, which stops charging every few minutes, even with the panel in direct sunlight at a perpendicular 90 degrees at noon. So even the ONE device that will charge needs to be babysat to be unplugged and plugged back in every few minutes. I have no such issues with the USB-A port, it charges reliably and doesn’t disconnect. Everything else I plug into the USB-C port will just flash the charging indicator at me, without actually charging. The USB-C port supply's voltage but almost none of my devices will draw any amperage or wattage, both figures remain 0. Also, the panel’s only charging protocol for 30w is some weird output I’ve never seen before which actually adds up to 33w. There’s no 9V 3A (27 watt) protocol, which my iPad, iPhone, GoPro battery charger, and several power banks would use to charge full speed. I don’t know how you can claim this USB-C port has a 30W output that works with most devices when it has no 27W charging protocol whatsoever. Therefore, even if the USB-C panel WAS working properly it would only supply 18w to my devices, NOT fast charging them. 18w is what the normal USB A Port supply’s, which is the only reliable port on my panel. Essentially this is an 18w single usb panel for me given these issues. Not sure if my unit has a defect Power delivery chip or what, u see nobody else has this issue. Not sure what to do.
