    • Well built, powerful, built-in controller with a useful status LED. Great company support.
Size: BC-12W Pro
I have two of these 12 watt 12 volt solar charger / maintainers. One I've had for over a year and used for a pontoon boat battery so it only is used during the 5-6 month boating season in Michigan. The second I just bought in July for a PWC battery. I love how well built they are. The status LED can tell you if it's charging, open circuited, incorrect polarity, shorted or fully charged (the LED is on the front of the unit so it's readily readable). It requires minimal exposure to outdoor lighting to operate, even charging a small amount in fully overcast conditions. I've used my volt meter in amp mode to measure current output under various lighting conditions and it works at least as well as advertised, if not better. The biggest reason I felt compelled to write this review is that about two weeks after receiving my second panel (bought in July 2023), the unit quit working reliably. It would work for awhile then quit (LED went blank even in direct sunlight) then mysteriously it would start working again . I contacted the company and they asked me to send a video showing the LED not working while the panel was in direct sunlight. Once they received and confirmed, they sent a new unit to me directly from Amazon without me having to send the old unit back. In all it took about four days from contacting the company to receiving the new panel. This company deserves our business from both a product quality and company support perspective. The new panel I received is working very well so far and the panel I've owned for a year has worked flawlessly since purchasing in July of 2022. ... show more

    • Solid Solar Charger
Size: BC-10W Pro
This solar charger constantly keeps the two batteries on my 2001 Ford F250 charged. This vehicle sits unused and unstarted for months at a time and this charger keeps the batteries at 13 volts. I liked it so well I bought a second unit to keep the battery charged on my John Deere skid steer. These chargers are subject rain, snow and below zero temps at 9K feet in the Colorado mountains and work flawlessly. ... show more

Easy to connect. I have several of these on my mowers, tractor and RV so batteries last longer and are ready when I need them.

    • Great slow charger
Size: BC-12W Pro
Well made and waterproof. Use it to charge my trolling motor battery. Will not keep charge up with my 55 lbs thrust Minkota but will bring it back up in 8 hrs of full sun. Fell off the boat once at speed with no ill affects.

This solar charging panel has been installed on a swim platform for the past two years. It has performed flawlessly even when continually subjected to rocking in the waves during the summer and cold outdoor winter storage.

    • great customer service
Size: BC-10W Pro
I used this unit to keep the start battery on my fishing skiff charged up. It did a great job even in winter low light conditions it could get a full charge and hold it. However, after about ten months the controller started to work only intermittently, then it went out altogether. I contacted the company and they replaced it immediately so I'm back in business. Great customer service. ... show more

    • worked better than expected,,,,but.....
Size: BC-12W Pro
So, I have the 12W/12V one. First, it comes with plenty of connection styles. So that is a plus. I have a battery on my utility trailer which runs the electric jack. I use this so I do not have to hook it to truck all the time. Love it. It charged the battery from dead dead and it now keeps it sustained. I did not permanently mount it so I can take it down easily Now the bad. The battery has the SAE connector for ease of connections. (to avoid reading the rest I will put a note here and tell you the connectors on the solar panel wires are reversed.. read on if you need an explanation)... As does this solar charger. So, there is no way to hook it up wrong. And the battery is hooked up correctly (red to positive/black to ground) . Having said that I hooked the solar panel (supplied with the panel) SAE connector and the LED light on the solar panel LED blinked weird. So I looked up the code on the Solar panel instructions and it says it was reverse polarity. Again, I can not hook it up wrong. So, I had to use the alligator clips (and reverse the clips on battery) to get it to charge. Works great now but I cannot use the SAE connectors as it is backwards. Weird. Minor inconvenience but it should be mentioned. ... show more
