Brunton 81-300737 Solarflat 2W / 6V Solar Amorphus Brunton 81-300737 Solarflat 2W / 6V Solar Amorphus

Pros: Quality - This panel is well built, with quality materials. The frame is very solid aluminum which is about as weather resistant as it gets.

Simplicity - The wiring panel is easy to get to, but still well protected. The snap on cover isn't coming off accidentally, but the terminals are never more than a couple seconds away.

Price - Compared to a similar unit I was pricing at "the shack", this one has a better build quality and slightly higher power output (by 0.2 watts) at a slightly lower price.

Cons: Unclear Specifications - I'm not sure what the "6v or 12v" in the product description is about. If it were 2 smaller panels joined together in one frame you could double the voltage up to 6v. As far as I know you'd need to buy 2 of these panels and wire them together in series to reach 12v.

Heavy and potentially fragile - While I like the thick aluminum frames, I fear the extra weight could be a liability if these glass panels were dropped. I read reviews online where the panels were broken during transit. Luckily I had no such problems.

Other Thoughts: I bought 2 of these panels directly from botach, on second thought I'd have preferred to have newegg backing me up on my purchase.

I attached female usb ports to the terminals, passing through 7805 5+ voltage regulators. They are currently charging 5500 maah usb batteries(albiet slowly), which will in turn charge my various handheld devices.

It took me less time to put together the chargers than it took to write this review.

I may re-configure the 2 I bought into a parralel circuit to charge the battery twice as fast in the future.
