Brunton SolarRoll Flexible Solar Panel

The 14-watt version may trickle-charge a car battery, but it will take a long time to fully charge. Max output of the 14 is 900mAmps @ 12 volts. Your Yellow Top likes 13.8 to 15.0 volts, 10 amps maximum. (http://www.optimabatteries.com/product_support/charging.php)

It should be able to charge those packs but won't charge multiple items at once.

Check NewEgg for the adaptors. Some solar works @5.5v with a USB2-3 connector. Some works on 12-24v cording that you can get anywhere Coleman campgear is sold. WHATEVER you use, make sure it is correctly attached! I had one of my cheap little solars on charge too long. It went from flat to sausage overnight. Still works, though.

I would try contacting Brunton and see what they can do for you.

Did you have a question?

It would take an extraordinarily long time, but it is possible, Peter. Ryan makes a good point about Goal Zero, because they are designed to be linked together to take care of heavier charging tasks like a boat battery.

I don't think you can connect directly to the battery. You'd need a battery charger connected to a solar panel. Also I'd suggest going with the Goal Zero brand, top notch stuff.

The 14 would not be "too much" it would charge it faster. If you're going to the Pac NW you won't get as much sun so you'd probably need the 14. Going somewhere sunny like AZ and the 9 is probably enough. Take a look at the Nomad 7m from Goal Zero. I think it's a better product and though it doesn't roll, I think it's more packable. Also check out the 27m for even more useage.

You need the car cigarette lighter charger that's specific to the laptop. Plugs right into one of the included accessory cords. It's also nice (but not absolutely necessary) to have one of Brunton's Solo battery packs as well. What he would then be able to do is use the SolarRoll to charge the Solo during the daylight, and then use the Solo to recharge the laptop battery overnight. That configuration would also give him multiple charges for the laptop from just one good day's worth of charging up the Solo.

This will be hard pressed to provide the amount of current you need to power a motor and fan. Plus there is no battery, so you would have to have it in sunlight in order to function. I would look into some plain old batteries, with maybe a solar trickle charger that you could leave there and just let charge when not in use.

You need the car charging adapter that's made for your laptop, and/or the specific cables for whatever piece of electronics you want to charge. This doesn't hold a charge, but it will directly power whatever you're using. How long it takes is really a matter of what it is you're charging, but basically, depending on exposure, anywhere from a few hours on up. The best way to use this is to trickle charge one of Brunton's Solo battery packs, then use that stored power for use or charging your stuff. Also, you really should take it out and become familiar with set-up and capabilities before you take it out into the field and need to learn it when it should already be second-nature and you know what to expect.

An inverter would adapt the voltage, but would require more amperage than a solar panel could provide... 1.5 Amps at 120V (the input for my laptop power converter) means 15 Amps at 12Volts. Remember this panel is on 14W, so you can charge small batteries, etc. but would get only about maybe 60ma at 120V.

You want the Brunton Solaris 26 instead. Better output. As for the camera- go to http://www.bhphotovideo.com/c/buy/Power-Adapters-Chargers/ci/1099/N/4288586265 and look under your battery type. Try to find a battery dock for your type that will run on usb. Your plug-in factory recharger converts AC-DC when charging, so what you're trying to accomplish is to eliminate the need to use the AC from the house. A simple process, if you can find the right component. If you don't find what you need readily, or have any questions, call B&H Photo @800-606-6969 to tell them what you want to do, and ask them what they suggest.

Normally, what you need is a DC/AC inverter, but these types of panels and the sine waves from the inverter are hard to synch, so it's slow and unreliable, at best. You're talking about a good chunk of change to pull it off, so the best advice I can give you is to load up on spare batteries and invest in a $35-75 DC/AC adapter for the car's cigarette lighter. We use that set-up for everything from some fairly high-end cameras-rechargeable batteries-pumps-laptops...pretty much anything that needs power.

I wish there was an easier, cheaper solution, but I'm not only speaking from my own experience, but from a conversation with Chris at Brunton's tech support this morning. Good luck. Hope this info was somewhat helpful.

Yes there is. Brunton makes a few different sizes of a unit called the Solo. You can charge it up and, depending on what you want to run, it'll power it. The Solos can be charged using the SolarRoll, a DC car plug, or even with a typical AC household outlet. If you want to followup with what it is exactly that you want to power, somebody here can easily tell you which unit will fit your needs.

You will need to wire enough of these to get 70 watts of power from solar and then get an battery and inverter. You will use this keep the power regulated and so the lapotp wont break due to the change of power from the solar panels. I recemend go to poowerenz.com where they have different set ups and sytems. Also if u want buy there system without their solar panels and buy brunton. I recomend buy everything from powerenz.

A review here by Dave Watson mentioned he connected it to his motorcycle battery to trickle charge it, so as far as connectivity, you probably could but, I'm not sure what your batteries wattage output is, probably more than 14w...? This product is intended more or less for electronic devices that fit into a backpack, it may be worth it for you to buy a stationary battery charger instead.

As of right now, we don't have any of the 14 Watt on order. Thats not to say we won't get some in during the summer, thats just the situation right now.

If you simply use (or purchase) your car charger for your iPhone, this system will work very well. I charge my laptop computers, satellite phones, cameras, etc with this panel exclusively when on expeditions.

Should work fine with a twelve volt adapter.

No, it doesn't put out enough wattage.

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 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.

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.

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.

No, I'm afraid not. Hot plates usually need at least 400 watts to get to a respectable temperature. I'd stick with a cartridge stove or a liquid stove. They weigh much less, and don't require thousands of dollars just to power in the backcountry. ;-)

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 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.

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).
