Review on 20W 12V Portable Solar Battery Charger & Maintainer - Intelligent Charge Controller, Automobile Car RV Compatible! by Laura Turner

Revainrating 2 out of 5

Short Lifespan - my new review

Works great when it is working, longevity was three months. I have three of these panels, two are three months old, one is two months old. For no apparent reason, one of the three-month old panels stopped charging. It recognizes that it is under the sun, as indicated by the blue light, but it will not charge a battery. The 20w charging is great for keeping batteries topped off, but at 50 dollars and only three months use, it is not worth the cost.

Pros
  • ‎No
Cons
  • The charger may overheat during extended use
