DOKIOFoldable 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.

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.

If you’re looking for a 12 to 18 V solar panel with a very simple automatic controller to use this is for you. We have quite a high-powered electric fence made by Voss and the energiser will empty a brand-new 12 V heavy duty deep discharge golf buggy battery which cost over £200 within 2 to 3 weeks. I have attached this solar panel which I didn’t realise when I ordered it was 18 V but the controller automatically adjust it down to 12 V it has been working connected to the battery for six weeks. The electric fence energiser is still working, the charge rate is illustrated on the screen and it does exactly what it’s supposed to be doing. I am very surprised and very pleased.

So far so good with this product. Holding charge on leisure battrey even on cloudy days. Have only used item over 3 day weekends in caravan but so far so good

Excellent product charges my jackery fast .It's big and heavy the carry case doesn't look like it's going to last long I wouldn't trust it I would have paid extra for a heavy duty carry case .But the solar panel works faultless Excellent piece of kit

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!

It looks like the instructions have been translated from another language. The English is very poor and the instructions are, in places gibberish My particular concern is the safety instructions- these are vital to the product and are very poorly written.I have updated this review due to very poor response from Dokio companyI contacted the company forwarding below informationDear Dokio... This third instruction sheet you have attached is in a foreign Language- not English. My message via Amazon had to be severely shortened due to No of permitted characters. I am now enclosing my full response- You sent one set of instructions which were unintelligible.I messaged you and you stated the instructions were sent by mistake as they were a training copy. You sent me a second set of instructions and this is my fuller response to the second set. Sadly this instruction sheet is only marginally better than the extremely poor original. The English sentence structure is poor, this may make it dangerous to use this item as the user is guessing what the instruction may mean, rather than being sure of the meaning. Some words make no sense in the context used - two examples are "parameter" and " Precise temperature compensation" odd terms are used to describe important elements such as " Please connect the battery on binding post of controller" I think this means " Connect the solar cable to the battery terminal" This instruction should also define which colour cable to the relevant positive/negative terminal. The instructions are written in highly complex language and very difficult to follow., Perhaps a simple " Start up" guide would be helpful, with the other information provided as well .- (like most mobile phone guides) The first thing a user wants is:- pre fit safety information then how to safely install the item. Then how to turn the controller on The user cannot even see the control panel information until this is achieved so all other information follows naturally after fitting.. I think you need to get an electrician who knows English well to re write the instruction sheet so it is safe and clear for users. I do hope this is helpful. Unfortunately there are so many problems with the instructions it would take me hours to work through them, even then I could not be sure I would be correct as I simply cannot understand the meaning of much of the document. I have a reasonable amateur understanding of electrical goods but this one had me totally confused. I believe you have a good product here and I have mine working now by trial and error fitting . I am writing to you as I believe good instructions would greatly enhance your product sales online where, probably, most customers are buying direct and not for electrical businesses....Sadly the same response came from Dokio on each of 3 attempts at feedback - they simply asked for a photo of the issue... This response was most unhelpful and indicated they simply had not taken notice of the feedback.
