Best portable solar power pack to charge laptop ?

BEFORE READING THIS: I'm not looking for a USB charger, there are plenty of those.
I have been looking around for a portable solar power pack. I found this one ( www.ebay.com... ) but the review stinks and I don't really want to gamble with 130 bucks and its shipped from Taiwan but Amazon has one shipped from U.S. , still even with all of the adapters Im not sure. Im really looking for someone that has a tried and true product for solar powering a laptop, NOT an ipad or tablet that can be powered USB. Maybe a camper that needs his laptop for working 3 hours a night like me. I have the jetpack for wifi but I need some power. Any tried product recommendation would be appreciated.Thanks

you need to look at your laptops supply voltage and since most laptops are DC devices you should be able to daisy chain the panels and by pass the charger brick so you won't need to worry about inverters

I think your looking for a juice box.
It may be more than your after, but as the old adage goes, you get what you pay for.

While chaining the solar panels will increase your voltage, you wont get enough current. If done in parallel it will increase current but not voltage. Cant have it both ways. Battery is the best bet. removable car batteries are another option. Store all that power from the sun for a gloomy rainy day.

I know you'll need some box of tricks between the panels and the laptop to regulate the power and to cover the vagaries of the weather but as a start you'll need to know whats needed as a base figure
