Allto Solar120 Watt 18V Foldable Solar Panel Kits + 3 Charging Ports, Portable 120W 12V Solar Battery Charger + 10A MPPT Charge Controller for RV Camper Trailer Van Power Stations

The panel comes in a nice carrying bag. Fold it out, and extend the "legs", and you're ready to charge. It comes with connections for charging batteries, and USB connection for charging electronics. We plan to use it primarily with our camper to charge battery when camping. For testing purposes, since camper is closed up for the winter, I tried the charger on a smaller 12v battery I used for other purposes. The charge controller keeps you informed while charging the battery. It all worked great, even though I had a partly cloudy day for testing. I think we will enjoy having the panel available when camping!

I was looking for a reliable portable soar panel for mixed use (charge auto battery, phone, tablet, & other portable devices). I have installed fixed panels on my RV's since 2004 and enjoyed the freedom they provided. The portable panel had a high bar to meet for me to like it. I purchased several "cheap" systems in the 30 to 60 W range and 3 were junk (but they were really cheap). The 4th system was reasonably good but not easily portable and not cheap. The Allto Solar system while not cheap ticked all the boxes and had some bonus points.The folding system is a reasonable size and comes with most of the cables you would need (except the USB charging cables which came with those devices). When I connected a USB-C phone it was charged at hi power, and my tablet didn't complain about "low power charging". Using the supplied cables & controller I was able to get a charge rate of 2.4A into a small battery that was almost dead. This was done in February in Florida on a sunny day (which was better than any of the other systems I tested).In my short time test, this is the system I will take on this summers trip to Alaska to keep the phones & tablet charged to take that load off the RV's batteries. A long term report will need to wait about 6 months but the prospects look very good. The quality and thought that went into the product is evident and worth the price. Their solar controller was flexible enough that I ordered a second one for use in another system I have.

So far had it out a couple times and in mostly direct sunlight I was able to get around 45 to 50 watts output from the charger controller charging an LFP battery, haven't tested the output directly. Not as light as a flexible full size panel but more portable.

I've mostly used this to charge batteries: and for this it works perfectly. What I like: 1) quality (it feels solid, and looks like it will last being carted around), 2) the carrying case is not some flimsy grocery plastic bag quality case - it's a real cloth stitched, 3) a plethora of cords for every connection type, 4) the fact that it's two pieces and can be angled towards the sun is very useful. What could be better: there could be a pouch on the carry case for all the cords, and 2) possibly the efficiency of the panels could be better (when it was sunny and light was direct, the output was great / when it was cloudy it seemed to struggle a little with the current. It still did charge both my snowmobile and motorcycle battery in a couple of hours. If it did this - it should be overkill for things like cell-phones and other battery-backup generators. Overall I am pleased.
