I have a truck for sale and needed to park it at the end of my property for display. The battery would die out after less than a week so I thought I'd give this a try since it came with the 12V plug and was regulated. I swapped out the clips for the cigarette lighter plug and found the instructions helpful. I propped it up using a round container so it sits against the windshield (1st picture). I had a blue light in direct sun before I plugged it in, and then after doing so I got blue and red lights, indicating it is working. This is supposed to not create any parasitic draw when it is dark, so I'll give it a few days and see how it does.UPDATE- Day 1 was sunny, day 2 was cloudy and it rained most of the day. I checked it in the afternoon and saw the blue & red lights were on (2nd picture), so it appears to be working as designed. I plan to give it a week and see if the truck starts.UPDATE #2- It's been about a week, so I took my voltmeter & on a sunny day I got 12.78V at the plug with it disconnected. The truck started fine, so I can say at this point the panel is working properly.

I'm charging 3 boat batteries simultaneously and it's up to the job. Saved me from having to haul them out of the boat and take them home for storage/charging.

This is my second Powoxi charger. I use them to keep marine batteries charged to start my boat and run a second battery for the stereo system in the boat. The first one has kept the boat starting battery charged all summer and I expect the new unit to do at least as well.

Attached magnets on the feet to hold on the metal roof of the bulldozer. Has withstood tree branches hitting them. Still work!! Very good. Had to use two as their are two batteries in series to make a 24v system.

There's not much to say about this. I put it in the sun. Connected to a battery with a 12.2 volt charge. Came back a few hours later and it was much higher. Easy to use.This is what I am going to use to keep my boat batteries charged. No need to keep them plugged into the house.

Placed panel on the inside of windshield of my 1999 chevy truck and used the the cigarette plug in for charging source to battery. The cigarette lighter was tested and showed it was a hot connection with ignition key not used. The solar panel was tested and indicated 11-12volts output. Panel was facing East and South. There is a constant battery draw from my aftermarket alarm system and I thought this solar charging panel would compensate for the battery voltage loss, but did not. Usually if truck was not started after 8-9 days battery voltage would drop to 9-10 volts and would not be enough to start truck. Truck was now not started for 14 days with the solar panel installed and truck battery was full dead. Battery showed .05 volts? Had to call roadside service with a high out-put jump starter to start. Disconnected solar panel. Truck now starts fine after 4-5 days on it's own.
