Please include the manufacturers specifications or data sheets when you make inquiries. It makes it so much easier to look and respond without having to do a search for the different parts and what they are.

That tiny solar panel (7w, 7 volt), will barely have enough power to charge A cell phone OR A bluetooth.

It cannot charge a 12V battery, and it would take a week to harvest enough power to run a laptop for 10 minutes.

Sorry, it''s back to the drawing board.
or check my .sig for the link to my Solar Monolith - it might jar loose an idea or two that may
help you.

You can place 2 batteries on the bottom, which act as ballast, and the shelf holds chargers and other goodies.

I used 60W flexible amorphous panel, but using a poly or mono panel, you can get higher efficiencies, with the
risk of breaking the glass.

I like the battery, just get a plastic Marine Battery Box to haul it around in. (about $15)
I've heard of the brand of controller you mention.
The briefcase PV is my worry. It might look sexy, but only 30 watts ! For that price,
you can buy a full size 200W panel, and have - - 200 watts. For half that price, you
could get a 100W panel, and be able to power everything. Wrap the edges with foam pipe insulation
and you are nearly all set.
The drawback with a 30w panel, it will take 4 hours of sun harvest (10 am - 2pm) to run your
laptop for 1 hour.

Many people under estimate their loads, and the sales brochures over state the capacity -
Cell phone, MP3 player 1-3 hours , Smart phone, GPS, USB camera 2-4 hours and neglect to tell you that it only works at 8,000' elevation where the air is thin and the sun is strong. otherwise, it takes the 7w panel, 2 days in Florida to accomplish the recharge.

Look carefully there and see if you see the problem.
I start Jury Duty on monday, and will not have much time to keep going over your shopping lists for you. Maybe someone else that has built a portable rig can offer suggestions too ?

Unfortunately, this is a good example of winging it, and throwing money away by guessing.

Even when using small-scale projects, unless you know your power consumption, one is nearly guaranteed to go straight to "deficit charge" jail. Do not collect 200 dollars. In fact, throw it out the window.
