you really need to check the output/charging rate and be sure that it is equal to your ac adapter..less I guess is ok, but more is a no no

Actually, less won't work and more is ok. It won't supply more power than the Mini draws for charging, which is 25-30W, but if the solar device can't maintain that much, it won't charge the battery. The voltage needs to be 19-21V.

The first one does not give any specs, but based on the product description, it supplies 5V at a fairly low current (probably less than 500ma, which is 2.5W).

The second one charges its internal battery but as it has a USB jack for output, that tells you again that it's 5V.

Neither one will do anything for a Mini.

Same thing. Unless it says it will charge a laptop, pass it by. When it talks about MP3 players, phones and cameras, you know it's low voltage and low current.

I agree it would be a lot cheaper just to buy a 6 cell or a 2nd 6 cell..more cost effective I think..

Sorry to hijack, but I have a similar question. I'm looking to charge a Mini 10 with a solar panel. Would the 20 watt version of this solar panel, along with this charger do the trick? Thanks for any assistance.

My guess is that it's unlikely to work. There are probably significant losses in the 12V adapter. Note also that the rated capacity of the panel is in full sun.

So here's the deal. I'm wanting to bicycle tour (with a trailer) and I need to keep a laptop charged. I expect partial to full sun most days, and at least 6 hours on the bicycle (solar panel atop the trailer). What would your ideal setup be? I sucessfully did this once before with a solar panel, an auto adapter, and an old iBook, but it took forever to charge (8 hours was about a half battery's worth). The iBook used about 60watts, though... Any insight would be appreciated.

I was considering charging a 12v battery pack, then using that to later charge my laptop (and phone). Perhaps that's the way to go...

Or maybe directly charge the laptop battery with a standalone charger.

So many options, so little knowledge about this sort of thing! Help me holmes4!!!
