DOKIO Foldable Portable Solar Panel 200W 12V Monocrystalline Solar Suitcase with 20A Controller

**Update - I reached out to Dokio support 9 months after purchasing to request support for the controller. They shipped me a new controller and leads within 2 days, which solved any issues I had as indicated with my review is the controller below. Excellent customer support, thank you** 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, and the design means the solar elements are facing outside when packed up, which isn't ideal. But it's self supporting, and the large bulky size means it is less likely to be blown over when in use. It's rated at 200W, with the label on the rear of the panel says the rated current is 11.13A @ 18v. This means, with a good controller, you should expect a charge current of about 14.7A into a 12v (13.6v) leisure battery. In reality, I've only managed to pull a maximum of 10.2A from the unit in very bright summer heatwave sunshine (this is measured after the Dokio PWM controller into a 13.6v leisure battery, so 140W roughly), and typically it's about 7.5A - 9.1A in bright sunlight, so on par with some of the better 120-150W units. This will charge a 100Ah battery in about 12-13 hours assuming you have the sunlight strength all that time. When connected to a better MPPT controller, output does increase by about 10-15#%, but it's still not 200W. So overall the panel is good but not exceptional. Whilst the solar panel is fine, the charger PWM control unit is not so great with its user interface, although it is quite efficient in finding the power for a cheap PWM controller. It's completely unintuitive, not helped by the instructions that come with it and a generally bad interface design, unlike the previous Renogy unit I used. MY PWM 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 before the controller and at the battery showed it was actually supplying about 8A. However I may have a faulty controller unit. On the useful side, the PWM unit will power a light source and two USB devices directly from it. The PWM controller isn't, however, weatherproof and needs to be positioned 'indoors', which is a shame since ideally one would stick this onto the back of the panels. 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, typically on a par with a good 150-170W panel, but it is solidly built/bulky and heavy as well. But it was decent value for money at 115 quid to be fair. I've rated it 5-star because 4-star would be a little unfair because it works reasonably well and it's very good value if you can get it for the price I did, in reality it's a 4.5 star from me overall 👍

This set up is perfect for me, the power output even in low sunlight conditions is perfect, I run 3 096 sized agm car batteries and it keeps them topped up no probs running fridge lights chargers tv etc etc, nice travel case my only gripe is transporting them, when collapsed the solar panel is facing outward it would of been better inward to protect them a bit better but I just put it all in the box it was delivered in with some foam and had no issues, the controller is easy to use it comes preset to just connect up and charge, all in all, great set up, great price and performance, recommended

Used on a week-long camping trip in typical UK variable weather conditions of torrential rain to bright sunshine. At it's worst ( late evening / heavy overcast ) it was putting out around 1A-2A ; At it's best ( bright sunshine ) it was up around 12A-13A, and that was without messing around looking for the optimal angle. As is often the case, various screws/nuts were looser than I liked and required tightening. The mounting points for the support brackets feel somewhat flimsy. And whilst not directly related to the panel itself, the supplied carry-case leaves a lot to be desired -- whilst the case material is sturdy, the stitching on it is definitely not! Just as well I was only carrying it with the bottom of the panel only a few inches off the ( grassy ) ground, as the case carry-handle ripped completely away the first time I used it! Don't know if it's an isolated issue, but I'd strongly suggest testing it beforehand.

Yes, it’s heavy, but it’s well made. Bought it along with an Aferiy power pack, just set it up, hazy sunshine but putting 140w+ into it. Very happy chippy. The intention is to let the LPG do the “heavy lifting, solar for lights, tv etc. burt it will run madam’s hairdryer etc. Intend buying 2 50w LiFe batteries, one backing up, other on charge. Great buy.

Heavy and cumbersome but works great when set up, keeps my caravan battery charged

Very very good

Solar panel is great but i give it 3 stars as it is not compatible with Jackery 1000V2 the adapter seems to fit but it does not charge. However it is compatible with V1 Jackery kit!! This was extensively tested this weekend. It was good at charging my caravan via the MPPT controller that comes with it even in low light it managed to keep everything topped up. Just wish they would list what it is and not compatible with properly.

Works brilliantly straight out of the bag very easy to connect to the caravan. Legs are a bit flimsy so just be careful when moving it pick it up don’t slide it they will bend. A bit heavier than I was expecting it to be . Would be better if it folded up with the solar panel inside to protect it better during travel . But all in all very satisfied with it.

È un buon prodotto, si trasporta facilmente, è Rende bene, funziona bene, compratelo...

Zelfs met de winterzon heb ik een mooi laadresultaat voor mijn 1Kw batterij.

Zestaw ok polecam

Bonne qualité

Fungerar utmärkt, bra när man är ute o fricampar de
