i went on a 3-days/2-nighter last weekend and since my iphone is my camera nowadays too i bought this one to keep it charged up. i don't have an ipad so i can't test how it performs with it though.

it comes with 3 cables, from left to right: for charging the battery pack with the solar panels, female-end cigarette lighter adapter to use with the solar panels, and a cable to charge the battery pack using a usb port from a computer. on day hikes, i'll leave the panels at home and just bring the battery pack as backup.

there are 8 reflective cord loops around it so you can hang it just the right way to soak in the sun.

the battery pack can only charge usb devices though. you can't use the female cigarette lighter adapter with it.

it will only use rechargeable nimh batteries (the instructions say it). i tried using regular aa batteries and the led light will work but it won't produce power to charge a usb device. also, on older models i saw a aaa battery plastic adapter was included but not anymore - gotta buy it separately now :rolleyes: talk about nickle and diming...geez.

the internal pocket can only fit the battery pack and the two smaller cables though.

the whole package (9" x 6.5" x 1.5") fits inside my backpack's top lid just fine with plenty of room to spare. it should fit most mid to full-size backpacks' top lids as well.

the solar charger is kindy finicky when it came to charging the battery pack and my iphone 4. as the sun moves, it's best to check up on it every 2-hours or so and move it accordingly for best angle. you can't just lay it flat on the ground under the sun and leave it there all day - well, maybe if you're in arizona desert or something. it's winter here now so the trees have no leaves anymore but they still cast giant shadows on the ground and it's too easy to completely block out the panels. all it took is a few secs of shade and the panel aborted charging my phone. if i unplug and plug it back in then it "reboots" it.

i have yet to measure the time it takes to charge the battery pack using a computer at home though (i'll update this thread when i get a chance to) but it takes just under 2 hours for it to charge an almost drained iphone 4 then the battery pack is completely drained. overall, i'd rather bring the battery pack only as opposed to the solar panels only to charge my phone. i'll bring both on multi-day trips but i won't expect much from the panels unless the conditions are perfect for it.
 
I have been looking for a good solar charger for my bobs. I just haven't found one that has fit the bill yet. good review. I'll look into this one
 
I have the Goal Zero 7w panel and Guide 10 battery pack for hurricane season (and to fool around with)...took under 4hrs to charge 4 AA Sanyo Eneloops (they come partially charged) with the solar panel, compared to 2hrs with a 120v charger for the other 4 AAs... a nail driven vertical into a section of plywood, adjusted so the shadow falls upon itself to get vertical Sun rays... test done in August this year ... clear sky, high 80sF...
 
Thanks for the review!!!!

you're welcome!

excellent review... looks like a solid piece of gear, talk about being prepared !!!!!

thanks, rob. 3-days without access to bladeforums while in the woods is a serious survival situation! haha.

very nice. thanks for the testing info! much appreciated.
 
How does it work with your phone? They had these at the local costco a few weeks ago and I was about to buy the kit except I read a lot of reviews saying that it would not charge their phones, and the phones were all different so it wasn't brand specific. I'm still considering it mainly for charging batteries for my gps and other gadgets.
 
i picked up the led light last week. there's no spec listed but from comparing to one of my flashlight's modes it's putting out around 40 lumens - perfect for around camp.

kinda finicky with the iphone 4 but it will charge it. another guy on another forum posted it won't charge his 3gs but works with his ipod classic and the ipod touch. i guess you'll have to try it and see. not sure about costco but rei and goalzero's website has a good return policy.
 
When shopping for this kit make sure it is the Guide 10 "PLUS" Kit with the Nomad "7".

Goal Zero is phasing out the regular Guide 10 battery pack...The "PLUS" model has a "1amp USB output port"
opposed to the .5 amp port.

The battery pack stores 10 watts of portable power, easily charges flip phones and most hand held GPS units. A fully charged battery pack charges my iphone 2.5 times...approx. (it will not charge the new Motorola Droid 4 GS)

The Nomad 7 will charge my Iphone 3 direct from the panel but it must be ideal sun, no clouds and you have to plug it in the phone then power the phone completely down then restart it. If a cloud passes over you have to repeat.

Let me know if you folks have any interest...maybe I will post some for sale, in the correct forum, in the near future.

I bought a Goal10 plus battery pack for my son when we are camping so he can have some time with his games. I put the solar panel on my Christmas list so I might get that later. So far the battery pack is payiong off as my son gets 3-4 full charges of his iTouch off it and that keeps him happy over a week long camping trip with a bunch of play time while he doesn't have to be bored surrounding by adults. Yes he does participate in camp but I see no reason for my trips to not be enjoyable for his wants and wishes too. Just stating that in case someone thinks I am letting the kideo just veg out at camp :D. Sanyo makes the Eneloop batteries that are NiMH and I am going to try those in the Goal 10 Plus and see if I can't extend it's use by carrying another four charged batteries.
 
JV3 any longer term updates? I was looking at these on Amazon. The reviews were less than technical.

the solar panel was completely useless the first 3 days after the power went out (due to hurricane sandy) since it was very cloudy. i wouldn't rely on just it recharging my electronics when it's not summer...a cigarette lighter inverter is far more reliable year-round...sunny weather and it works as advertised though.

also, for some reason i don't know yet the energizer lithium batteries (way expensive compared to normal aa batteries to boot) in the battery pack failed to charge my cell phone. aside from the goal zero brand batteries (which is nimh batteries), the energizer rechargeables also worked (also, nimh). all my gear are used hard but i gotta admit this battery incompatibility caught me off-guard...good thing i didn't stock up on those lithiums.

lithium on the left, rechargeables on the right:

the battery pack with the light stick saw a lot of use though and it was awesome! i actually ordered another set of battery pack and light stick for backup. for this blackout, my cigarette lighter inverter was far more useful in recharging stuff. one thing i'd like goal zero to make is the ability to charge the battery pack directly from an outlet too. as it is now, i had to plug my laptop to the inverter just so i can recharge the battery pack via the usb.

here's a thread i started that includes other things i learned during the blackout: http://www.bladeforums.com/forums/showthread.php/1008328-after-hurricane-sandy-lessons-learned
 
JV3...my Guide 10 pack with Sanyo Eneloops charges from an AC to USB charger... right side of picture... it is a 850mA charger but a 1A is available... all run on AAs

with a 12vdc female tubular tap ending in a pair of battery clamps, a separate 12v / 120v controller charger and a couple of packs of Eneloops...and a few cables.... you have most of the electronics and lights covered... I've tried to standardize my hurricane stuff to AAs... I don't have a lap top, so I run old school off a couple of 12v auto batteries
