X-DRAGON 70W Monocrystalline Foldable Solar Panel (5V USB with Solar IQ + 18V DC+ Parallel Port) Water Resistant Charger for Portable Generator,car Battery,Cellphone, Tablet,and More (18V 70W)

bought 2x and used them for almost 2 years these are amazing solar panels for emergency home use and very portable for campingpeople who are giving 1 star reviews have no clue on how to use solar panels; you can tell from there review pictures. 1st thing you never lay solar panels flat on the ground at 0 degrees they will only be efficient at high noon for 15 min.for panels to work properly you have to set them at an angle towards the sun and it depends on your location for summer its 25-40 degrees depending where you live and winter its 55-70 degrees again depending on where you livei simply use a piece of card board at an angle and lay the panels on the boardputting 2x together in parallel configuration i got 120wtts hitting the max load for the batteryif your new to solar farming please watch some you tube videos first this is not a plug and play hobby, some knowledge is required

Peak output I've seen is 58w out of my charge controller. 40-50 was more normal. I got this on sale for $60 summer of '24 which would make it about $1/watt. For that price I think it was a screaming deal.My goal is to run radio gear in the field. For that I use a low-RFI, MPPT charge controller by diysolarforu. USB is a nice bonus and charging a laptop will be done post-charge controller with a charger I trust.Open circuit voltage is 25v and the highest amp reading was about 4.3A. I'd be hesitant to directly plug in a laptop I cared about. The one I didn't care about was too dead to take a charge, so no test data was obtained. Voltage between the output and parallel connection port seemed to track with each other. Ie, when my charge controller said 18.5v (under load) on the top port, voltage was the same on the side port. Interestingly, the positive pins seemed to be directly tied together while the negative had 37k ohms between them. But the voltage was still the same.I didn't test the USB extensively but I know I measured 1.3A, 5V out.The panel is easy to deploy and has lots of loops to anchor it. Folding is easy but it traps air inside that takes a little while to get out of the fabric. The pocket was well done. A powerpole connector would be nice but I can't figure out how to open up the output housing without destroying it. All in all I'm very happy with it for what I'm doing.

Use while on vacation in the Caribbean, set out in car windshield to charge the power banks for later in the evening to run lanterns and phones.Great to have charging capabilities when in 220v areas!!!

I purchased this as an Amazon return for $118 and it's worth every penny. I use it to power my iPhone and sometimes my computer and it doesn't take long at all, and that's usually through my living room window. Once folded up its footprint is surprisingly small. I highly recommend this portable, powerful little solar panel.

Equipo bien disenado y eficiente al usarlo

The media could not be loaded. Excellent product but the wire is too short it should be at least 2 1/2 m that I can put the solar panel inside the car not outside it.

just what i need will get second later

Love this thing. Its a game changer for backpacking.
