  • Perhapse one of the larger panels would do a better job
  • but I think they could have done a better job with this solar charger.
  • this does the perfect job of keeping my battery in my 2003 Toyota Tundra charged..i only drive it 1-2 times a month, and always had to jump start it
  • Is currently on top of a shipping container and does a great job keeping my vehicle stored in there charged.
  • This panel does a great job of keeping the battery on my runabout fully charged

Reviews around battery top (4.61 of 5)

  • Have a property without power and this is great for keeping the battery topped during the summer and healthy over the winter.
  • Took it on a 10day camping/hunting trip, and it was perfect for keeping battery topped off
  • I bought this solar charger to use on my tent trailer to keep the battery topped off
  • Sometimes seems to work ok sometimes, but it's really hit or miss as to whether the battery is actually charged when the light on the charger says it's charged.
  • I park the vehicle facing south and it gets sun all day which keeps the battery topped off.

Reviews around advertise (4.49 of 5)

  • Works as advertised, it has been hooked up to my camper for a couple of years now, and still going strong.
  • works as advertised......even shuts down when battery is charged
  • Has worked as I had hoped so far, I will update my review if I have any issues
  • Great product, works as advertised it won't charge a fully drained battery if you have an alarm and GPS as the power draw is greater than the input but will keep it charged for those periods that you can't ride.
  • Works as advertised, although I could only get it to work well when both terminals were connect to the charger.

Reviews around work (4.40 of 5)

  • This works great for keeping a battery charged on my pontoon.
  • the "charger" works great to maintain a charged battery for exteded periods of non use but did not work to charge a low battery.
  • This item does not work/is defective
  • I will be returning it back to the company and may try another one and hope it works.**UPDATE, after talking with a company rep it is now working perfect
  • This should do the trick!6.7.17- well, it isn't working

Reviews around watt (4.13 of 5)

  • However, with the battery known to be full (charged with the ac version of this product), the solar charger at the decent 10 watt always showed a yellow charging, after 2 straight days of solid sunshine and never went to a green fully charged status
  • but I got a reliable 12+ watts under ideal conditions.)
  • 20 watt is as low as I would buy and I would highly recommend a 30 watt or above system
  • Getting technical, 15 watts is not enough to prevent and reverse sulfation in larger lead acid batteries, the problem that makes this product important.
  • 5 watt is great for maintaining a motorcycle or small import car to keep battery topped off while it is sitting and not in use, but, this solar panel is lacking any real charging capability

Reviews around way (3.86 of 5)

  • I would strongly recommend this to any one that would like a inexpensive way to keep the battery charged.
  • Well instead of having to run an extension cord and disconnecting it every time the family wanted to go somewhere this was a more convenient way
  • Lesson learned the hard way...if you buy this unit, make sure you secure it so it won't topple in a breeze
  • Sometimes seems to work ok sometimes, but it's really hit or miss as to whether the battery is actually charged when the light on the charger says it's charged.
  • With having a HOA I can't run a wire out to my racecar to keep the battery charged and this is a great way to keep it full

Reviews around unit (3.66 of 5)

  • Not easy for an outside application (better if with a stand, etc.. I am worried about the indicator being attached to the screen hoping it does not encourage theft (a complete unit) as the solar is outside the garage, while the vehicle is interior.
  • Nice unit to keep the electrons going to my riding mower
  • I have started to fine a high percentage of post from people saying these units are failing in very little time
  • I realized this unit has not been working since I bought it, I had it connected to one of my vehicles to maintain the
  • I love these units I bought 2 of them and use them daily in order to maintain my

Reviews around charge (3.48 of 5)

  • I have used the Battery Tender that plugs into a 110 volt outlet on these same batteries and they are fully charged in 12-36 hours.
  • Excellent for maintaining charged my electric plant battery
  • Not good for vehicles.. had very little charge when using this
  • Sometimes seems to work ok sometimes, but it's really hit or miss as to whether the battery is actually charged when the light on the charger says it's charged.
  • Now the control unit has apparently failed and the charging LED only flickers occasionally

Reviews around weather (2.18 of 5)

  • In defense of my particular charger, it has been through some brutal weather conditions since I purchased
  • Winters in northern Michigan are brutal and the truck sits outside taking all the nasty, cold weather mother nature can dish out
  • Sometimes seems to work ok sometimes, but it's really hit or miss as to whether the battery is actually charged when the light on the charger says it's charged.
  • It has been through a few hail storms and some tough winter weather last year
  • We have had some of the craziest weather on record in New Jersey

Reviews around day (2.02 of 5)

  • On a hot day the edges of this charger can get hot, so i would advise to leave a window or 2 cracked to let the air flow
  • Mine is in the window and charged up my motorcycle in a day (cloudy day at that).
  • It takes about a week in normal (mixed) weather to recharge after a good day fishing, but as I mostly only get to the boat on the weekends this is fine for me
  • is my dump trailer in about two or three days after several dumps Also keeps the winch battery on my car hauler full.
  • Have been using it since mid winter and it charges with no problem even on cloudy winter days.
