Brunton SolarRoll Solar Panel

It has three male plugs, one at 2.5mm, another at 3.5mm, as well as one at 4.0 x 1.7 mm. It has a 5.5 x 2.5 mm female adapters with center pin positive.

Yes it would. You would carry the battery charger and plug that in to recharge the battery. The USB cable would not work for recharging.

Yes, it can recharge your camera battery. If your camera did not come with a car adapter, you will need to purchase one, which usually comes with a replacement battery charger. A quick search on the net found one at Amazon for less than $5.00. Make sure the charger is specific to the camera model.

The EOS is very specific on it's input power, so using the USB cable could have disastrous results. Essentially, you need the Canon charger, but with a car adapter. The Canon charger prevents the battery from being overcharged.

The time necessary to charge the battery on a long, bright, sunny day is two hours minimum, since the battery charges to full in 110 minutes with the 110v AC power adapter. In real world vs. ideal, I would say it's closer to three hours with the 14W version and 4 - 5 hours with the 9W.

To answer your questions:
1. Yes, it comes with the cigarette lighter socket (most Brunton solar products include this adapter).
2. Highly unlikely. Most modern electronic devices have overcharge protection, which includes laptops, iPods, iPhones, most cell phones, and many cameras. This is not absolutely universal for all electronics, so you should look at the technical specifications for your device or devices if you are uncertain (typically, though, if the device plugs into an outlet and/or a computer to charge, and can remain in that state indefinitely, you are fine). The controller is most often used when charging stand-alone batteries, or battery packs, which are susceptible to overcharging.

It really depends on the brand of the laptop, not the OS, but yes, it will. Read the description.

Check the Brunton website for these things, and you'll see that they claim the 7.5 or 15 can charge a laptop by itself. However, the rolls should act like any other battery, in that you can increase voltage by connecting them in series, or amperage by connecting them in parallel - i.e. two of the 3.4s should yield 11 volts DC at .5 amps or 1 amp at 5.5 VDC. You need to look at your power adapter and do the math to figure out what you'd need. If you're going to try to connect two $200 rolls together, you should really do some research into circuits first, if you don't already know what you are doing.

Keep in mind, as these actually AREN'T any other battery, the standard disclaimer of "SHOULD" doesn't mean that it will. Tinker at your own risk and don't blame me if you loose your eyebrows and your solar roll.

So what ARE you doing with a laptop on the trail?

What the hell are you doing with a laptop on the trail?

I'm not sure if I'm the one to answer this question because I am kind of seeking the same information. I just bought the solarroll (9 watt) and now don't know how to hook anything up. All of my cameras and laptops do not take the male and female plugs.
I believe the only thing you can do is buy all of the car chargers for the products you want to charge (because the solarroll comes with the car charger).

I talked to a Brunton tech rep about a system that would help me charge a laptop, sat phone, AA batteries, and a GPS for fieldwork in the arctic. He suggested I use the SolarRoll 9 with a Brunton SOLO 7.5 amp/hr lithium polymer storage device (see: Amazon). The SOLO weighs about 4 lbs., has an inverter with a 3-prong outlet, and would be safer for charging a laptop. I haven't tried this yet - may end up getting the SolarRoll 14.
