First one I received was damaged in shipping but Amazon made it right. The second one was fine. Easy to setup and keeps our camper battery charged. I was worried about the tempered glass because we sometimes get hail here. Well, it went through a significant hailstorm and did not sustain any damage. Overall I think this is a good solid kit.

Put these on automatic storm water samplers to keep the batteries charged. Working great so far, installed 6 months ago.

There's a lot of bang for the buck with this unit. To power my telescope I use (2) six volt sealed lead acid batteries used in series for 12 V to power a simple cooling fan and a small computer (DSC) used to find astronomical objects. After a night of viewing, a small (12 V, 10 Watts) solar charger is the perfect way for me to recharge the batteries while I sleep during the day. This little unit comes with a built in charge controller (you buy this extra on a lot of solar panels) This maximizes the charging cycle and prevents nasty things from happing. For example short circuits, overcharge protection (turns off when battery fully charged), parasitic back charge (power back to the panel when not illuminated) and will not charge an inadequate battery. I had a personal issue with my battery being bad and the unit not working. I reached their technical service department by email and John was great at helping me resolve the issue. Tested the unit with new batteries and it worked perfectly. The instruction sheet was missing the information that would have been useful for identifying how the unit would act trying to charge a bad battery. Things do get lost in translation sometimes. Bottom line, Excellent unit, Excellent customer service!

Works fine for my lawnmower but did not keep my motorcycle battery charged. I ended up buying the 30w version and it seems to be trickle charging my motorcycle battery fine.

I have purchased this Sunerpower solar powered trickle charger to charge my boat battery off-season without removing the battery and putting it on a battery tender in the garage as I used to. I had been using the Deltran 15w Battery Tender solar trickle charger ($140) until a tree branch fell down and shattered its glass. This unit looked appealing due to the more traditional solar panel mount, which as you can see in my picture is on a tree next to the boat. I like that I can bend the bracket to fit the tree and angle the charger up to the sun. Upon installation, as many other reviewers have commented, the charge light was solid red indicating reversed polarity to the wires. My boat battery is connected with standard SAE connectors and extension cables (red+, black-) and I never had an issue with the Deltran. According to my volt meter, those wires read -12.86V, so it's actually the SAE extension cable reversing the polarity not the Sunerpower unit itself. To fix this there are three options: reverse the leads at the battery so that the red+ is on the negative battery terminal and vise versa; purchase a SAE reverse polarity adapter off Amazon ($6 for two); or use the included cables that come with the Sunerpower unit. As I didn't want the hassle of undoing my winterized boat cover to get to the battery and considering I prefer to use the extension cables exactly as they are, I chose the cheap Amazon adapter (see picture of tree) which arrived in 1 day. Immediately the charger was fast blinking red indicating active charge, and within a day with decent sunlight, the charger turned green indicating a full charge to the boat battery (see picture). What more could I ask for? So buyer do note that this unit is quite simple and nice and hopefully sufficient to charge and maintain a single deep cell battery, and I like the ability to view the charge status underneath which I couldn't do with the Deltran unit. But unless you use the supplied cables, you will most likely need to reverse the polarity on the wires which is a very simple fix. PURCHASE THIS UNIT WITH A SAE REVERSE POLARITY ADAPTER. Happy charging.

Simply does not work. When connecting to battery "correctly" getting solid red light. Contacted support who stated that those who use battery minder connectors, the red and black wires need to be opposite; this resulted in blinking red light but appeared rapid. According to instructions, this means charging. However, after a week, my battery went low and as a result, the CO sensor inside trailer was chirping. I then, switched the connectors back to the correct way and getting solid red light. I have no idea what is going on. Refuse to buy a voltage or current reader. Just not happy with this thing. Sorry UPDATE: 11/15/2019 I can’t say enough about customer service. After my review they reached out and offered to help. They were detailed and persistent. I was using third party extension cable that had a larger ring terminals from battery tender or minder. Told me to swap the red and black when using this brand but after a week, the battery died and thus the bad review. With their advice, used the cable provided and with the correct red and black it appears charging. BUT I don’t have a voltage meter and can’t tell if it is charging enough to keep it topped off. After expressing frustration, they gave me a full refund anyway. I feel bad to accept this since no need to return. It isn’t fair to them since I haven’t seen this over long term to see if panel works. I will update this again but couldn’t be happier with service. This means that you have nothing to lose with purchasing this product
