Ratings & Reviews+

Schumacher SP-400 4.8 Watt Solar Charger/Maintainer is rated 3.0 out of 5 by 2.
Rated 2 out of 5 by from My high hopes were quickly dashed. Something in my vehicle is drawing power and the battery drains after about 4 days on non-use. Purchased this charger along with the matching overcharge/discharge protector. After reading the manual, it says it is not to be used in the car (unlike the picture on the Walmart website). The panel must be ventilated and they even suggest putting it outside the vehicle. This is not an option when you are parked at an airport, an apartment complex or other public area. I'm not sure how this is even accomplished without crushing the cables in the door. ... Returned for a refund.
