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.

This is my second purchase of this brand of solar panels and I really like them. Quality product for an inexpensive price. My first panels lasted 9 years with yearly use. I like how light and portable these are. I get 13.9 charge, they come with a digital connector and a kit of tips. They can be hung up or propped on the ground. The variety of plugs allow for difference power stations. I have a jackery and I use the Anderson connector or the tip connector that comes in this kit. Ive spent winters in the AZ desert, camping in the mountains, boondocking, etc. These panels are great!! I am extremely pleased with Dokio! (P.S. I actually like them better than my Jackery panels!!)

Lets just say this is my first solar panel and charge controller bought for my micro-camper trailer, a TAG. When received from UPS the box was flattened and was unsure if panel, etc. would be in workable condition. After opening this very thin and semi-flexible panel it did have one corner slightly turned in. So I was unsure if it would work. Got the instructions out and poured over them trying to understand what the procedure was for setting up. Actually it is pretty easy once you get your wires connected properly (I substituted my #12 wires for the thin versions with unit). I used my own 12 gage wires and connectors so as to not modify any of the parts if I had to return panel due to improper shipping container. After doing what I read to keep a short length of wire from controller to battery and making the longer length from the panel to the controller I did not notice that one should always plug controller into battery before connecting panel. Testing with only controller connected to panel yielded nothing. Once I reread and found the "order" of connection with battery to controller first and got my wiring proper to + and -, and was out in sun, Panel and charging came to life! I saw as high as 20+ volts from panel o charge controller and around 2.4 amps. Charge controller did its job of not overcharging battery when up to 13.8 volts So I feel this will work as needed in keeping the battery up to snuff in non-connected shore power camping events. I will just have to make sure to watch the battery level when discharging with on-board fan and 12 volt cooler and lights. Did see over 13.8 volts to controller even with cloud cover. Panel itself is very light and protective 'outside" cover works well. But as panel heats up in sun exposer it gets more flexible, so you might consider making a "stand" to support it that can be also folded for storage. I also have added a thin towel to between the panels when it is folded for storage to avoid panels rubbing against each other. While testing I used a digital volt meter to insure proper use and connections--a must. I have since mounted charge controller in protective and water tight Tupperware clear tub to lid of trailer outside accessory box near the solar connection on outside of trailer. Wiring and controller are contained inside accessory box until needed and then run the connections for charging. Solar charge controller can be viewed when trailer accessory lid is open through clear top of Tupperware container or as top is removed for better clarity. Used 3M red auto accessory double-sided accessory tape to supplement mounting Tupperware to trailer accessory box lid.

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!

This is the second DOKIO solar panel I have purchased. The first one was purchased back in 2020? and has served me well. The glass panel on the roof of my Tacoma is flat lying so I use the plastic panel as a back-up when the sun gets low or when it's partly cloudy. I have two 4x4s I use to explore the back country. The plastic panel (of another brand) I carry in my 4x4 van no longer puts out the amps so I thought I would get something I know is going to work and take the abuse it gets on my camping trips. I plug the panel into my vehicles solar charging system but it comes with a controller that I have used to help someone else, or use as a stand-alone battery charger. I admit I have not used the new panel yet so I am hoping it's the same quality as the old one. If not I will be back here changing my post.

First let me say that I had no intention of using the included charge controller, I already had a good controller salvaged from an upgrade to another implementation that I intended to use. But this kit was cheaper than the similar panels offered without a controller and I thought I could use the included controller for other implementations. Any way the controller smoked when I first hooked it up for testing and seemed to lose some functionality but was still charging the battery. I hooked it up today with my Sunsaver controller and it wasn't charging. I unplugged the panel and checked the panel output and noticed that the current from the panel is reversed, the red wire is - and the black wire is +. I switched the connections at the controller and it is now charging. Otherwise the panel is a good buy, it consistently outputs 21+ volts with no load. I'll have to see how it holds up over time but I'm well pleased with it right now and would recommend it, as long as you are not depending on the included controller. Edit 3/13/18: Used the panel for a week of dry camping trip to maintain the battery in my truck running a 12 volt dc fridge/freeze while parked at the campsite. It not only kept the fridge running but kept the battery fully charged. Edit 11/25/19 Not quite two years old. The panel still functions as good as new. With little more than 4 to 6 months actual use It is showing severe signs of UV deterioration in the fabrics. Most noticeably the edge binding is becoming a little ratty. One of the d-rings pulled out due to UV damage to the fabric loop it was sewn into. I'm continuing to use it but lowering my rating to 3 stars. I think I will probably be replacing it soon.

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.

This panel is very lightweight and folds to less than an inch thick. It does work and charges up my Jackery, but even in moderate Texas sun the highest input it got was 35 watts. It did make 20-25 in light clouds, so that’s pretty decent. Good for the money and what I do with it, which is charging a power station during the day.

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.

fonctionne parfaitement ! Excellent produit !

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 !

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.
