Review on 🌞 Apowery 20W Solar Panel Kit: Monocrystalline, Battery Maintainer + Charge Controller – Ideal for RV, Marine, Off Grid Systems by Paul Rose

I have a large minivan that draws enough standby power that I'm worried about leaving it parked unused for more than a week or two. During COVID I have often not used my van (this is the second car) for a month or more and the battery has died a couple of times. Small 500mA solar car chargers can't even keep up with the leak. So that large control panel and controller, as well as the cigarette lighter plug and battery, are always 100% charged when I need them, even if I'm just standing in direct sunlight for a few hours.
