I have followed this thread since the beginning and wanted to chime in with the direction I went.
Having a black camper van means I prefer to park in the shade and most of the areas we camp are heavily tree'ed anyways so a portable panel has always been my primary consideration for this application.
I decided to spend a little more money hoping to get a better quality panel that wont end up like the dokio, or the mohoo above.
I chose the Lensun 100 watt portable,

Mine came in a camo bag, sans logo or controller, just two MC4 pigtails. The cordura type bag is super durable, and these are the ETFE laminated panels.
Similar to the Acopower, (linked above,
https://amzn.to/2HAvC9f ), the Lensun has a built in stand which makes it easier to optimize output.
As a side note, I completed the system charging 150ah worth of battery with a Victron Smartsolar Charge controller,
https://amzn.to/2Hzn42l, this has the built in Bluetooth and works great. I also purchased this 80' 10awg extension cable,
https://amzn.to/2l0Fv7q, cut it in half (making it 40'), so the MC4 connectors are on the panel side, and attached a 10g SAE quick disconnect
https://amzn.to/2LCvpF4 on the controller side (with a tension relief) for quick deployment.
The 40' of cable coils up in the bag sewn into the side of the panel so I can pull out as much or as little as I need.
