DOKIO150W 18V Portable Solar Panel Kit (ONLY 9lb) Folding Solar Charger with 2 USB Outputs for 12v Batteries/Power Station AGM LiFePo4 RV Camping Trailer Car Marine……

Bought 2 of these and took them on an 8 day boondocking camping trip in my 5th wheel to charge my Goal Zero Yeti 1000 power station. My wife and I use the Goal Zero Yeti 1000 to run our CPAP machines at night. I also used them to charge the 5th wheel batteries. Because of several factors (like clouds and the way I just threw them flat on the ground), I still had to run my gas generator a few times. Here is what I discovered:1. I love these panels and just bought a third one. I also have two heavy Goal Zero 100W briefcase solar panels but they are so heavy I don't like them. Much prefer the DOKIO 160W 18V Portable Solar Panels. Much easier to store.2. They never produced 160W but my Goal Zero 100W panels never produced 100W either.3. I love the battery management control box that comes FREE with the DOKIO 160W 18V Portable Solar Panel. I can hook it directly to my 5th wheel lead acid batteries and charge them to full capacity in a few hours (time varies because of lots of reasons).4. The cheaper DOKIO 160W 18V Portable Solar Panels don't have a kick stand so I had to lay them against a rock or just lay them flat on the ground. This made them less efficient but I didn't have to keep adjusting them like I had to do on the Goal Zero briefcase 100W ones.5. For the price of one 100W Goal Zero panel I can buy 2 DOKIO 160W 18V Portable Solar Panels.6. In the morning I lay them flat on the ground, hook them up and don't mess with them until the sungoes down.7. I just bought a third one and hope I won't have to run the gas generator at all (depending on the weather). If three isn't enough I will buy a fourth one and leave the Goal Zero ones at home.Bottom line: If money is no problem the best solution is to have permanent solar panel system installed on the roof of your RV. But if you buy solar panels you can't go wrong with these DOKIO 160W 18V Portable Solar Panels. Besides while I'm saving up for my home Tesla solar panels and back up batteries, I can use them at home for emergencies. Easy to lift and slim to store in the garage. Highly recommended.

Charged Bluetti EB3A solar generator with the 160W Pro and the 220W Pro panels on separate occasions.The Dokio160W Pro panel, fully charged the EB3A from 19% in just 2.1 hours, pretty good IMO. I noticed the watts input charge fluctuated from 98-105 watts, is that low, good, average? Could I have placed or aimed the panel better, maybe, but it was clear skies during the charge time. Anyhow, I liked the relatively short charge time.The Dokio 220W Pro panel input charge fluctuated from 128-140 watts under similar clear sky conditions, however, I used a clip-on solar panel sunlight aim device for the 220W panel and temporarily used chairs to fine tune the angle. However, it only made a 3-8 watt difference vs just eyeballing the angle. The EB3 calculated the 2.0 hours to fully charge from 0%.Both panels build and materials are very good, they should last many years.The 160W is lighter, easier to set up and maneuver than the 220W model. Buyers can decide which one to get, they are both good. Please note, the 220W specs indicate a max output of 200W.The panels include a voltage controller, a fistful of plug adapters and various cables to fit multiple solar generators. The plug adapters are too easy to drop and disappear while camping. Avoid those hassles and purchase an additional MC-4 to 8mm extension 10FT cable to keep things simple.

I like the size, weight and portability of these panels. New to mobile solar charging and I realize this is a very entry level plug and play kit, but that’s what made it appealing. Really easy to use to charge solar generator or camper batteries. Two downsides as many others have mentioned: (1) no stands, so you need to prob the panels up on something. Since there is 4 panels, can be kind of tricky to get good alignment while propping up. (2) After some testing on a clear, sunny July day, that was around 80 degrees, most watts I pulled was 94. Would be happy if it was a 100w panel, but it’s not, it’s claimed to be 160w. Pulling about half power is not terribly impressive. Overall, would I recommend - likely, because of price, accessories, plug and play capability, and maneuverability. Wish efficiency was better.

Bought this 160w panel as a companion to a Bluetti ac180. I put it out and got an average of 115-120w which honestly for this time of year, the time of day, etc. is right around what I was expecting from it. It folds up and stores away easily and came with multiple charging adapters, even though I only really needed the one. I'm not really reviewing the charge controller because I don't need to use it, but it does seem cheap like others have stated. For my needs, getting roughly 120w (most likely more later in the year) of portable solar panels for this price was a steal.
