DOKIO Foldable Portable Solar Panel 100 Watt 12 Volt Monocrystalline Solar Suitcase with Waterproof Charge Controller

Very good value. Seems really robust and works well in the winter sun/shade. Looking forward to using this in the warmer weather.

Very easy to set up. Works well on our camper. Highly recommend.

See heading.I'm not sure what the "bad" reviews are on about. Most seem whinging about extremely minor things, like the leg a a little bit awkward to set up (they're not unless you have 6 fingers on each hand) or the controller is NOT waterproof (It's clearly stated it isn't. Maybe spend 5 seconds reading the instructions and the sales pitch on Amazon?)Anyway, I bought a 3 meter extension lead as the one that comes with this kit s not long enough for me. Not an issue. Also bought a longer controller to battery lead (One meter max as stated in instructions) again because for my purposes the included one is too short.Made relevant hole in caravan battery compartment to slip lead though. Attached to battery terminals. At camp site, attached battery, checked controller, which was working. Then attached solar panel and hey presto, it started charging the battery. Was a cloudy day with no direct sun.Over the five days I was at the festival, this kit kept my battery charged so I have no problem running the lights all night, had I so wished. Didn't need to make any adjustments to the controller whatsoever.The only question I have is, what is the downside if I have a lead longer than 1 meter between battery and controller? I could do with a longer one so I can munt the controller where I can see it inside the van, instead of it being under the seats.OK, bag isn't best quality, but what you gonna need it for? Backpacking with this kit across the Alps?Other than that, only time will tell how long it lasts.

This is not a bad solar panel to be fair, but there are better options out there for a 200W portable unit in terms of size and efficiency. It is very large and bulky, but it's self supporting. It's rated at 200W, although the label on the rear of the panel says the rated current is 11.13A. In reality, I've only managed to pull a maximum of 9.2A from the unit in very bright summer sunshine (this is measured after the PWM controller), and typically it's about 7.5A - 8.3A in bright sunlight. This will charge a 100Ah battery in about 12-13 hours assuming you have the sunlight strength all that time.Whilst the solar panel is fine, the charger PWM control unit is pretty awful. It's completely unintuitive, not helped by the awful instructions that come with it and a generally bad interface design. I'm a chartered electrical engineer and it took me about half an hour to figure out how to configure it. I still have no idea about some of the settings. Clearly designed by someone who hasn't a clue about user interfaces, unlike the previous Renogy unit I used. The unit also doesn't show the current supply correctly, it was indicating no current supply from the solar unit but a quick check with a multimeter at the battery showed it was actually supplying about 8A.On the useful side, the unit will power a light source (although not sure of this logic since you need bright sunlight to do so...🤔) and two USB devices directly from it. The PWM controller isn't, however, weatherproof and needs to be positioned 'indoors'.The package comes with a handy cover, which is fine but it's pretty thin and unlikely to last long looking at the stitching!So overall this is OK but not amazing. Had I the option to send it back and swap for a different unit, I would, but I want able to test it in time after ordering. But it was decent value for money.

The media could not be loaded. Arrived safely. Sturdy construction. Came with good instructions, was easy to set up. Stand was easy to set up. Carry bag seems strong. For the money, seems very good. Looking forward to trying it off grid.

I have just used this on our caravan for a long weekend away off grid. I plumbed it in using a a hedge cutter plug & socket (can't get polarity wrong & weatherproof) & it performed well in mostly overcast conditions. The controller is useful, showing battery & panel volts, load, amps, etc. At one point when the sun really shone, it was charging at 5 amps & charging two phones at the same time from the USB sockets on the controller. Well chuffed with this!

Item is exactly as described and works really well.
