Worth the $
Works perfectly for what i need. Its super easy and compact, I place it on the roof of my vehicle and strap it down with small bungee cords (incase of wind) and it easily pulls 135W from 11-5 summer time. The cords were a bit difficult at first to detach but i got the hang of it after a few times, just have to use a fingernail to press the latch to unhook. I haven't used it in winter yet but i will update when i do.

Very lightweight and packs down small!
This was my first Renogy product. I ordered this because the size was interesting. I was skeptical of the quality but this pretty nice! I laid it on the windshield of the truck and leaned against the porch. It is hard to get all the panels to line up the way a portable panel with legs does. But I realized this panel has a different function so I can’t really compare it. It got about 20W less than my PV2000 BLUETTI panel but given the way this lays out, I’m okay with that. It is very light weight and fold easily to the compact size. I tried on the backpack straps that it comes with and it’s quite comfy to wear. See photos, I’m 5’7” for scale. The pocket is. Ice to hold the straps if you don’t want to use them and it’s holds the cable with MC4 connectors without having to jam them. I appreciate the many loops on it to make hanging easy for different setups. Would need to buy some clips for that. The highest I got in testing today’s output was 146 watts in late morning but it’s late in the year (mid-Sept) and I’m in Montana so the sun is lower and I have clouds off and on. Again, I don’t expect the same rating as a more rigid panel. If your traveling with limited space such as car camping, this is a must have!

Flexible use for panels
I am using this solar panels for camping and also on my boat. Spread it out over the Biminy top on my sailboat. Adds 400 watts to the existing 400 watts I have using hard solar panels. Fold it up and leave on boat when I am not there. Works great.

Renogy 200 watt solar blanket
This was a game changer for me. I put it across my windshield where it ‘collects’ the sun, keeps my car at a cooler temperature, and adds privacy. It is compact and rides in my front seat during travel. It is much more effective than any of the suitcase or flat panels I’ve used. Lots of passing strangers stop by to ask about it. I should purchase stock in Renogy!
