There is a continuous advancement in solar technology. Manufacturers are creating powerful, small, portable rigid/semi-rigid mobile chargers for recreational users.
We have described here about three of them to find out what makes sense, and here are our thoughts on these solar chargers.
Pros: This is a lightweight, 8.3-watt solar panel including a 10-foot fused power cable with a factory-installed SAE quick-connect output. It is packed with three options for linking: alligator clips, ring terminals or a plug -- all with SAE termination.
Cons: Alligator clips are subject to rust mostly in saltwater conditions. Caution should be taken with SAE connectors. They should be covered with electrical tape to avoid shorting or separation in unusually wet conditions.
Pros: This is a panel using a built-in three-step built-in automatic microprocessor charge controller with LED indicator lights. It includes a 5-year warranty. At the 10-watt output, this panel is perfect for nominal as well as being a consistent trickle charging.
Cons: It is heavy, weighing in at a hefty 5.5 lbs. Optional connecting methods (ring terminals, auxiliary plug) are available for an additional price. Connecting cables should be longer.
Pros: This model has a 6-watt sturdy panel, well-designed, and features a two-year manufacturer's warranty. It is weatherproof with a resistant protective film coating that is great for rugged boat duty. Additionally, it has a big stress-release fitting in the panel and a 10-foot fused power cable.
Cons: The battery-connecting ring terminals appear to be somewhat light. Alternate connector options have to be purchased separately.
