My battery is dead

I bought this for my 2014 Ford F150 6.2L which has never had trouble starting and has a great battery. I'm going on vacation for 4 weeks soon and thought it would be a good idea to park the truck at the airport while I'm away to make sure it starts when I get back. I bought and tested it this week. The truck's battery was already showing 12 volts and spinning like never before. I connected the panel through the cigarette lighter as I wanted it to be a fuse. It showed 14.5V and 0.5A straight…

Really drains the battery.

I am very disappointed with this charger. After my mechanic diagnosed my 2018 Chevy Silverado with a very low battery drain (he thinks it's computer related and difficult to troubleshoot), he suggested I try a solar charger. I did a lot of research and based on the reviews and the seller's insistence in the Q&A, I settled on not draining the battery. I gave the thing a few chances, tried different connection options and made sure it got plenty of direct sunlight. Well, the good news is that I…

Must own a car for good weather. BMW e93 2010 ideal!

I have a 2010 BMW e93 that only gets 3,000-4,000 miles a year. So 4-6 weeks pass between the starts. Long story short, I'm tired of running it every 7-10 days. After a while that wasn't enough and I got cc id 415. I connected the red to the strut in the engine compartment and the black fork to the nut on the strut mount and that was it. Wonderful. The charger keeps my battery fully charged. I drove for six weeks and when I put my hand on the door the car came alive as if it were a daily driver.

Pros
  • practical item
Cons
  • reliability

Great panel but READ BEFORE BUYING

Nice panel BUT if you plan to use it to charge a car battery read this. It consumes some of the power from the battery when there is no sunlight. With the ammeter on my multimeter, the current is positive when the panel is in the sun (charging battery) but negative when the panel is not in the sun (discharging battery). It only discharges at around 3mA, so I think it's only the little green LED on the back of the panel that draws power. Also, there is a red LED on the included cigarette lighter

Pros
  • Weight
Cons
  • Almost OK

This is a great solar charger/companion device.

I tried several brands and returned before keeping this one. The built in charge controller does exactly what the AC powered model does; It delivers the correct voltage during the three charging phases (bulk, absorption and float). Testing this panel on a fully replaced (12.9V) 35Ah lead-acid battery with a Bluetooth voltmeter showed that the voltage rose to 14.50, stayed there, and then dropped. for trickle charging 13.20V. This is ideal for lead acid. It only puts out 0.65 amps of sunlight at

Pros
  • Handsfree
Cons
  • Very expensive
