Portable Solar Power, Samlex Foldable Solar Panel, Off-Grid Emergency Electricity
The Samlex 135 watt portable solar panel with included charge controller will provide plenty of power to keep your battery charged when power is a must. This foldable 3 panel solution will keep your 12VDC batteries charged for those times when you are out with your RV, travel trailer or ham radio. During a hurricane or other natural disaster, powering your TV, laptop, phone chargers or lights is almost a must have. I plan on using this for my dual 12v coach batteries so I can utilize more room on the roof for permanent solar panels towards my main AC inverter which will power all the AC appliances in the trailer such as Air conditioning, TVs, coffee maker and outlets.
