QC could be better on the connecting cable, but still a great little panel.
Nice panel for hobby use or for messing around and working towards something bigger scale. I’m getting rated values when charging a small 3.5aH SLA battery and the connector assortment is great.Only bad part is that the wire connection broke loose after a few weeks from a very bad solder job on the ground wire pad. This is a very easy 1 min fix for me, but something I should should still not have to do.I would still recommend this panel to someone wanting to try out solar.

Love it!
Great solar panel! It’s the perfect thing to keep on hand for jumping a battery, used several times all ready. I also like it for camping, it’s much easier and more compact than the alternatives not to mention a lot cheaper! The panel is easy to set up and use.

No suction cups in either box
The first one I ordered did not come with the suction cups to mount to the window. I ordered a replacement and it also did not have the suction cups. I cannot figure out how to contact the manufacturer. Looks like a nice solar panel but if I cannot mount it it does no good to me. The included instructions say there should be 4 suction cups included. I guess I will have to order another brand...

Works Great!
Combined with a Battery Tender 021-1162 Solar Panel Charger Controller this solar panel keeps my 2 batteries fully charged on my 7.3L diesel SUV!

Works Perfectly, White Background is Undesirable
Great Product for the Price.The white background is very annoying if you place this in s windshield. It will bend and flex due to varying heat and cold. Works perfectly well, I will replace it when I can go up to a different MFG's $100.00 version.

Saves time & money
This charger has been extremely helpful to keep our lawn tractor battery charged. It seems if I don’t use it every few weeks the battery won’t hold a charge, and this solar charger takes care of that. Definitely recommend

Works good
My son in law likes this . He keeps it in his vehicle. He has had to use it a couple times to start his vehicle and uses it to charge his battery for his boat. Works good and can be used anywhere.
