DOKIO 100W Portable Foldable Solar Panel Kit (19x26in, 5.3lb), with Separate Controller and Dual USB, Monocrystalline Charger for 12V Batteries & Power Stations, RV Camping Trailer Emergency Backup

This kit can charge a lifepo4 battery. Maximum charge current is coming from this cheap pwm charge controller, it's only at around 14.6 volts max voltage from this controller with this solar panel. Which is enought to charge a 12v lifepo4 battery at 14.4 volts charging. The only trick to charge a lifepo4 battery more quickly, is to have full sun day on solar panels. Best to invest in a mppt controller charger, but not totally necessary for a small solar panel setup like this. 14.4 volts in full sunlight on this solar panel to charge your lifepo4 battery fully. Make sure solar panel face is facing sun at 90 degrees to sun for best voltage. These solar panels seem to work, but they are fragile. Do not bend them too much, I heard one making a slight crackling sound when bending slightly. Good to have or make a solar stand that supports this solar panel well so it doesn't bend much. Like make a solar stand out of pvc pipe and carriage bolts to make a folding frame stand. Nice to have this light weight portable solar panel. Does charge a 12v lifepo4 battery 50 ah pretty quickly. But better to buy another solar panel to get more juice to battery for when you have loads on battery, and for charging, topping off your battery much faster. Too bad that all solar panels are only about 23 percent efficient or less. Can you imagine if solar was 100 percent efficient ? You could then run the whole World off of pure sunlight !!! Plenty of power comes from solar if We could get much more efficient panels, controllers and batteries. We need about 50 percent more efficient solar for it to really take off, and for a forever energy source. Solar panels used in space by NASA etc. like on all satellites, work better in the coldness of space, if you chill a solar panel down in temperature you can get much higher charge current. Much More effeciency from freezing temps, on a solar panel.

So far so good. Over a month Most iv pulled is around 80watts without tilting the panel. Charges all of my power stations fast mid day. Bought it for portable, but it just works so good I kept it up!

I use two of these panels connected together to provide power to my travel trailer and they provide enough power to run the lights and water pump and charge our laptops and phones. The panel can definitely put out the rated 100 watts with full sun and an open sky. Here in Michigan, with often-cloudy skies and lots of trees, they usually put out less than that. Even so, two panels is generally enough. If I camped in the desert, one panel would probably be plenty. I bring a very small generator as a backup but use it very rarely. I've found that it's key to have a long power cord so that I can place the panels wherever I want on my campsite to get the most sun. 50 feet of cord does the job well. The charge controller provides a lot of useful information about the panels' output and I like that. Although it seems to really be designed only to handle the power from one panel, and it can overheat if I get several hours of very bright sun. I bought a different charge controller that can handle the power from both panels in full sun--I think it was $20 or less. The panels themselves seem to be of decent quality, though the sewing on the nylon wraps is poor quality and has already come apart in some places.

Excellent product. Does exactly as advertised. Been searching a long time for an affordable 100 watt, foldable solar panel, for my solar generators.

These panels are reasonably tough, but don't bend them. This is my second purchase of this brand, and I like them for use out in our harsh high desert environment. They fold out fully and can be laid flat on the grtound or propped on a bush.

I bought this a long time ago and hadn’t opened it until now. It’s missing the most important cable… the one that plugs the panel into the controller. What a huge waste of money.

Bought back in 2020. Safe to say my review isn't just a single trip review here. In all the scenarios I've been in, desert, beach, mountains, etc, I've never been able to get more than 2.5amps output. That's even in direct sunlight with perfect conditions and only happened a couple times. If that's all you need, this will work great for you as it's super light and portable. Unfortunately, for me, it just isn't cut out for what I need. I was hoping to produce slightly more power than my fridge requires during the day, figuring at night it's not going to be run constantly. In a perfect world, this should have made enough excess power during the day to cover the power my fridge needs and then enough excess to recharge from the previous night. In reality though, that just isn't the case. In reality I'm usually getting 2A output in the best of conditions. During this last camping trip my buddy opened up a brand new Renogy 200W solar suitcase and without even trying to get the perfect angle was producing 8.5A. So rounding down and making it simple math.... if he was only getting 8A... and my Dokio was actually 100W not 110W... My 100W is producing 2A his 200W is producing 8A, so I'm at half the output I should be at. I should have been able to produce 4A output. Oh well. It's cheap and light. Next purchase will be a Renogy setup as I'd rather have quality over saving some money/space/weight at this point. Having my fridge die halfway into the trip and having to switch batteries/run my Jeep's DC to DC charger is just not how I want to camp.

Works great! Easy to transport. You can charge devices right off the controller or hook to a RV battery.

Works fine. Also, for its wattage rating, it sits on my vehicles dash INSIDE the locked cab, secured from theft. Easy set up for my solar generator. Plug and play type thing. As it's described in ad. I've had other 100W+ solar panels that will not fit on my dash panel.

Bought this to keep my EcoFlow Glacier fridge/freezer charged while camping. Have gone camping yet but did test it out at home and it keeps the add-on battery topped up with partial sun in the winter.

I was looking for a way to recharge my Minn Kota designated battery without carrying it back to the campsite and generator while on extended camping trips. I found this on sale for an excellent price and I expect this will be the solution. Very portable, light weight, powerful solar panel that I will be able to recharge the battery in the boat.

Ne donne pas les 4.5 ampères comme devrait , et cela même si je met le panneau le plus au 90 degrés possible avec le soleil !donne seulement 2.3 amps! Déçu !
