Until recently I have used only the Brunton Solaris 26 folding panels for all my expedition charging- but this spring I added the Brunton SolarRoll 14 to the mix. Due to damage suffered during very high winds, both of my Solaris 26 panels were damaged and stopped working on my last expedition in Pakistan, leaving me with only the SolarRoll 14. This one panel charged my laptop, satphone, camcorder batteries, and camera batteries for the entire expedition. Very impressive and more durable than folding types. For longer expeditions get the Brunton Solo Power Pack- a MUST!

It has taken a little while to get this dialed but it is getting the job done on the glacier in AK.

I took the 9 watt version to Peru in August.
After a quick trip to the hardware store for suction cups with hooks, I was able to hang the roll in the window of the train.
I charged iPod, iPhone using the included cigarette lighter plug and an after market 12 volt charger. I used the included multi prong adapter to plug in a AA battery charger and charge the AA's that I used.
The roll worked great, took up little room and wrapping it around a water bottle in my pack gave me confidence it would not itself get crushed.
Free energy is a great way to go.

Have the 9 watt model and it works very well. Got this for charging Ipod, cell phone, and gps. Charges pretty fast in full sunlight, haven't really used it in cloudy weather yet so...? Is actually very light, only packing issue would be size as it can't be rolled to tight. Excellent idea if you're needing juice for extended trips. Comes with several adapters including cigarette lighter plug( you can use car charger, making it easy to find right adapter).

the brunton roll worked great. there are 2 outputs, and when i plugged multiple devices into the roll, it took double the time to charge. one device charges fast. make sure you have the correct adapters for your electronics before you leave on your trip.

I bought the 9 volt on sale to take while camping so I could charge my camera battery. It does not charge unless the sun is out so I don't know if I would take it to Vietnam or any other wet environments.. You must also make sure to purchase the proper adapters for your equipment.

I do wish you could roll it up a little tighter but wrapping it around a water bottle is an excellent idea as are the suction cups for glass. I used a small nylon cord and a carabiner to attach it to the sunny side of my tent.

Solar tech has come a long way. I'd like to see these work on a cloudy day and a drop in price as these are quite expensive. I don't think I would have purchased this had it not been on sale.

I've used this on sunny days using the 'car adapter' to re-charge AA and AAA baterries (using separate battery charger) as well as my cell phone. It works good as long as the sun is bright, a brief cloud passing overhead shut it down. Does not roll up very tightly - I was hoping to roll it up into a cigar sized diameter, but could only manage to get it down to a water bottle size as mentioned by others.

I bought my solar 14 roll from the internet with the vision of charging my laptop off the grid while traveling. After initial test I identified that it was unable to charge my laptop. I contacted Brunton and we arranged to exchange for another. After my second solar roll 14 arrived from Brunton, you can imagine how disappointed I was when testing identified that this solar roll 14 was also unable to charge my laptop. Bottom line is that if you are intend purchasing the solar roll 14 to charge your laptop in the sun (as the product description implies) then be prepared for disappointment. I have had 2 and neither of them have been able to charge a laptop.

It took a bit to tell if this was even working, but once it was it charged my phone and GPS just fine. I had a chance to demo this last year backpacking, was light, easy to use once you could see it was charging, and stored in the pack with really no extra weight.
