Question: how long is thw cable from the panel to battery
Document: I purchased the Coleman 36 Watt folding solar panel (manufactured by Sun Force) to take camping, planning on charging the battery for my pop up camper. My review is based on very limited use as it arrived twice from Amazon damaged due to inadequate shipping and product packing, after the second time I returned it for a refund.
The not so good fetchers were the weight, at 30 pounds it is not the easiest to maneuver and set up. The included stand worked but is not the best design; it doesn't stay together well, takes a bit of work to adjust and is not made to move once set up. The first panel I received was damaged; the face of the panel was shattered in one of the corners, however before noticing this I had it fully assembled set up and charging my camper battery.
Charging worked as well as I expected. Puts out about 65% of rated power even in bright sun. Fortunately knew enough about solar power to expect it. Stand is minimally functional. Needs extra support on any slope or especially uneven surface. Included cables nowhere near long enough to easily move panels to take advantage of movement of sun if there are any obstructions over between batteries and panels. Manual even more poorly written than most.
It looked like any minor impact on one of the corners was enough to shatter and crack the face of the panel. I'm sure I can find a lighter more durable panel to do the job.
In about 30 minutes it was, I thought working fine. After setting in the sun I noticed the damage and then tested the panel with the included testing light and found that the damaged panel was not producing a current. After sending it back and receiving a new panel, it also was damaged during shipping. After receiving this product damaged twice I decided that it may not be the best panel to use for camping.
Seem to maintain charged batteries being used on daily basis.
I just got this product a few days ago but here is what I can add to the other reviews: Does as advertised, easy to use, comes with all necessary connectors (great deal in fact because the same connectors sell separately for $18-$19). Word of warning because some people are really picky about this: the metal tilt arms are non-adjustable; not a problem for me but might be for other people.
For the price asked I don't think you'll find a better one. (also as a side note: Sunforce makes the Coleman model in addition to one of its own that looks exactly the same, the difference? The Coleman one has the same excellent quality with more wattage for less money :-D
Answer: It's about 4-5 feet long. Just barely long enough to allow you to locate the panels to get sun. I would prefer to have either an extension or longer cable, but so far I'm happy with the unit.
