I have 2 of these. Amazon had them even cheaper on there 3 day sale a few weeks ago. At the same time they had this controller, 100 watt compact panel, 10 guage cables and mounting feet for under $140.00. I had my son in law buy one for his pop up.
They have worked very well for me. I use 1 with the 100 watt panel I have mounted on my truck camper shell supplying a group 27 deep cycle. The other to a portable 100 watt to supply the group 29 deep cycle on my Scamp
. I followed what someone else did here and put suction cup feet on the portable panel so that I can set it on the Scamp
without scratching when the sight has little shade.
