Has advanced MPPT (Maximum Power Point Tracking) for high solar efficiency
Full 1 year warranty, even includes battery!
This portable folding solar kit is more advanced than anything on the market. It comes with a new technology called MPPT (Maximum Power Point Tracking) which makes tracking solar power more efficient and reliable. As Sunlight intensity changes, the voltage and current from the solar panel also changes. The MPPT continuously calculates and adjusts to maximize the charging power.
This kit also includes great features such as jumper cables for your car. If your battery dies, you can re-charge quickly, and get back up and running with this kit. It also includes a powerful Lithium-Ion rechargeable battery that can power your devices even after the sun goes down. You can also use the included inverter to directly power your laptops, cell phones and lights during the day.
This product is great for earthquake safety kits, disaster relief kits and for serious hikers and campers. You can use this in your RV, Boat, Home, Tent or anywhere there is sun. Never be without power again!

So basically, what you have is a 12V, 8AH battery that can be fully charged in 3 days with a solar charger...Had this set up been about $50, it would have gotten 5 stars. But this is $400 and marketed as the "most powerful on the market." So check your laptop charger, if it says 19V, this product will not work for you. Not even with the inverter. I thought that since it says it can power just about anything and that it runs at 110V, I'd be able to use that for solar charging my laptop...Nope, still not enough power. What this thing IS good for is charging very small, low voltage things like smaller portable chargers, cell phones, MP3 devices, small cameras, anything that can be powered by USB pretty much, or below 12V if it's not USB (which isn't a whole lot) which really sucks being $400 and all.
And finally, last but not least, after just a few days of using the inverter on a cell phone, it went kaput. Doesn't light on, power on, anything. The inverter also fit very loosely both into the charger as well as whatever you plugged into it.
I really had really high expectations for this thing, so I am very sadly disappointed. I am going to contact the manufacturer and see if maybe I just have a defective unit and if I can get a new inverter and update my post once I hear back.
I don't really think when it's a day of full sun, "angle" really matters lol...besides, it's meant to be folded which kind of implies you don't have to "angle" it anyway. It's simple, this is just a garbage product. For about $100-$250 more, you can get your own 100W (ACTUAL 100W) Grape off-grid solar panel (the ACTUAL best on the market...18% module efficiency which is the highest possible), and an MPPT controller (the controller with THIS product was so completely cheap and generic) which turns "leftover" voltage into current to more quickly charge your battery, a 110VAC pure sine wave inverter, MC4 connectors, cables, cable stripper, and a solar panel mounting kit (you can make your own plywood mounting platform to which you can mount it for 10 bucks plus 6 bucks for the legs). And for another $80, you can get a 12v 100AH battery. One 100W Grape panel with a GOOD mppt controller (morningstar sunsaver MPPT, or blue sky SB200E, the cheaper ones are not "true" mppt controllers) can charge, in full sunlight, a 12v 100AH battery within 3 hours.
So...just in math terms, if this product could only charge 1/3 of a 98Wh battery in a FULL DAY OF FULL SUN, a 100W panel should charge roughly 2/3 of a 98Wh battery in a full day of full sun...but this is not the case. Instead, this 100W panel charges a 1200Wh battery in THREE HOURS of full sun. So...again, if you do the math, where a 100W panel should theoretically be just a little over 2x as powerful, is actually close to 113 times more powerful and efficient! That tells me that this product is garbage and clearly has an extremely low module efficiency which is coincidentally not published. This wouldn't really bother me that much had it been maybe $100-$150...but $400 for something 113 times less powerful than something only twice the wattage? I didn't really think that negatively of this product until I did actually build my own off-grid solar panel system that works amazingly at just about the same price and saw such an incredibly improved performance. I mean, I went from this product that wouldn't even charge a cell phone fully within one day, to this new system that can keep my entire multimedia system (TV, 7.1 700W surround sound system with separate 12" plugged in subwoofer, ps3, modem, cable box, and random fans) going 24/7. I mean, that is quite a difference. And you could get away with being able to power your TV all day for about $500 for a home built system (if you're not looking for portable I suppose). I went on the high end on a lot of things, so I spent about $720 which included a $250 125AH AGM (gel/dry cell) battery.
What really gets me is even if this thing turned out current flawlessly, just the fact that it isn't compatible with anything beyond 12V gets me...How can you advertise as a laptop charger and not go beyond 12V? That's insane.
Anyway, now that I have my own off-grid system up and running (still "kinda" portable as it's not mounted to my roof and I can move the batteries around and the platforms around with a second person lol...) I am even more disgruntled with this product seeing this system put out 100 amps within 3 hours, again, 113 TIMES what this product can output. OH, and my panels are on the same "angle" as this product was lol...They do, however, have a GREAT marketing schtick!
The customer support has also been very good. When I first tried using the system, I let the battery charge for a few hours in the sun. However when I hooked up the inverter nothing happened. When I contacted customer support, though, they very quickly replied with some suggestions and assurances that they would do whatever it takes to make the system work. As they suggested, I charged the battery for a few hours through the included cigarette light adapter and then everything worked fine, including charging through the solar panels. Very satisfied and impressed. Several others have been eyeing it and might well be buying systems of their own.
I'd caution anyone about dealing with this vendor.
