Works great

When my wife got her Audi Q5, we opted to keep the 2013 Tahoe she'd driven since brand new so she can haul her trailer. The terrible winter storm earlier this year nearly killed the brand new battery which took over 24 hours on a charger to finally turn over. I immediately ordered this little diddy and there'll be no more worries or need for weekly start-ups during periods of no use. I opted for plugging it into the cigarette lighter receiver, laid it in the dash to soak up some solar power and the new battery we thought was ruined hasn't had a problem since. Its small enough that it's easily unplugged and laid safely aside when the Tahoe is being driven and I know she'll have no problems in the future. Anyone with spare vehicles should have one of these for each of them

Works like a charm!!

This solar battery charger was so easy to set up and use, plus it has already saved me money and paid for itself by preserving a battery on my boat which now cranks up on the first turn of the key. I thought that the battery was in its last days and that I would have to fork over $200-$300 for a replacement battery, but I think that I am going to get more years out of it due to this charger. Highly recommend.

Amazing. It Works.

I purchased this 12W unit July 13th & hooked it up soon afterwards to my 99 Porsche Boxer. Live in Florida but it definitely doesn't get 12 hours of sun a day. Went thru hurricane Ian but not direct hit. Just went out to start my car since it hasn't been started since early July. I was Totally Amazed it started right up immediately. Battery was fully charged after 3 months of sitting idle. So happy i bought this unit & highly recommend.

Winter Ease

I’ve got a couple of fairly large heavy batteries on my boat and at 70, they are a chore to remove and reinstall every year. I bought 2 of these, and using the suction cups to the skylights, I run the cords with the alligator clips directly to my batteries. The internal charge controllers are the winning combination here, as you don’t have to worry about overcharging or discharging. I’ve been onboard recently and both batteries are charging/maintaining perfectly. The suction cups are also doing their job.

3 month daily use review

It simply works. I have an older vehicle I use primarily on the weekends but often a few weeks will go by between uses and invariably the battery would die and I'd break out the charger. Royal pain. I bought another cheaper brand and after not getting any readings on the multi-meter I sent it back. Bought this one and spot checked the voltage for a few days and this (12 Watt) keeps the battery at full charge all the time. I keep the unit inside my front windshield angled forward. I do face south so when the sun it out it's in full sun for a few hours. For three straight months now every time I start my car it fires right up. I love a product that actually performs exactly as advertised. My dead battery aggravation is completely gone.
