Renogy E.FLEX5 Monocrystalline Portable Solar Panel with USB Port

My 10 watt panel works really well. I also purchased a Renogy power bank for my off grid hunting/ camping trips. Basically, so I can charge the power bank during the day while I hunt, then use the bank to charge my phone at night. I use my alarm on my phone to wake up in the mornings and check in deer/turkey. The solar charging and the power bank work well for this. I may be investing in a portable 100 watt suitcase for our pop-up camper set up for boondocking as well. Very impressed with Renogy's products so far. Nice job!!

Time will tell as to how robust the item is but for simplicity, ie a foldable, one socket usb charger with lash points it is a good addition to my kit. Do not have high expections that a 10w charger can solve all your problems but having it as an emergency item in case you need to re charge a phone, headlamp etc is incredibly useful and a safety matter.

Compact, effective, reasonably priced. A worthwhile purchase for those who enjoy outdoor activities like camping and hiking. The solar charging feature gives this unit a modest boost over other portable power packs.

Works great for charging small electronics. So far I've charged headphones, a smart watch, a renogy 15000mah battery, and a small bluetooth speaker. I plan to use it for camping and days at the beach.

Worked as expected. Have charged the battery on two separate occasion in full sun. It took about 5 hours for a full charge. I positioned the panel to maximize sun exposure and re-positioned after about 2 hours. Also tried charging on a overcast day, worked as expected, it was not very effective.

Great product. Works great. I am able to charge the my phone in the backyard. I will take it camping with me where this is needed most.

It's very light weight, easy to carry. Sits perfectly in my truck window. I need to use the specific charging cord for my phone. I cannot use an Amazon cord with my Samsung phone with this model, though I can use it interchangeably on AC.

I've been using this to charge a power bank that I can then use to charge or power my USB devices. It works well even in winter in the midwest where the sun is not great. I was happy to see that it came with carabiners and suction cups. I wanted to attach the panel to my window in the house. I would have given 5 stars if the suction cups were usable. They came so misshapen that they don't even stick to glass without the panel attached.

The product is exactly what I expected. My staff are really happy with them. However, I did order 30 units and only 3 were shipped. I was happy with the resolution of the situation.

Really impressed with the build quality. I was concerned at first because after plugging in an iPhone cable I received an "Accessory may not be supported" error on the phone. However, I think this was because of a non-Apple Lightning able and not anything in the Renogy circuitry. Once I got the juice coming into the phone on a sunny day, super happy with it. I would love to see some kind of rubberized flip down cover over the USB slot but other than that... thanks for a nice product!
