RFI: Backpack Solar Panel

Need someone smart about this to shed some light.  

So I'm interested in procuring a system to recharge my phone, tablets, and battery pack etc. 

I have looked at GoalZero's systems and also looked at Anker Panel (only). I would like it too be back packable and 20W's range (open to all idea's). 

What are you using and what are you doing ?

My solution depends on what I will be doing. If going for a 1-3 day backpack  hunt I have found that small battery packs are lighter and give more versatility. Something like https://www.amazon.com/gp/prod...00?ie=UTF8&psc=1 but there are tons of options out there,  just depends on budget and capacity needed.

 It takes about 7 days in the backcountry for me to justify carrying the weight of a Guide 10 charging kit.

Do you have the Anker that you link? 

I like it ans I feel it's a good start to a full system of Solar panel and battery combo. 

Do you use rechargeable AAA or AA Batteries?

I use a Dark Energy Poseidon. I'm sure by now there are lighter units with more MaH I just posted a well reviewed unit as an example.

With the Solar unit I bring rechargeable AA and AA. Most everything in my pack runs off those. Plus the kit has a USB to charge a smartphone..

Not sure what your intended use is but for camping in the back country our group uses biolite stoves. A bit heavy and doesn't boil as quick as a gas type burner but is very versatile. We usually pack in  hot dogs and use the grate, also works awesome for back straps on a successful hunt.  A little slow on the charge and you have to feed it quite a bit but charges the iPhone in an hour and a half.  On our third season of using it now.

I should have laid out a better brief on my desired use plan. 

Day hikes and adventures in the city (power for multiple phones)

Multiday hikes (AT and PCT) in the future.

Airplane flights for 10 hours 

Using AA and AAA rechargeable for portable device to reduce cost of batteries for Garmin. 

So I think the battery pack with a high capacity and reachable AA and AAA batteries with charger that can charge via USB and wall outlet should be my first step and then adding a solar panel to harvest power during hiking breaks. Also being able to supply power to multiple devices simultaneously.

She unfortunately hasn't had a chance to use it other than verifying that it worked. Sorry man.

No Stress. Thanks for asking.

I have a goal zero Nomad 7 that I use for backpacking and general camping.  I generally charge a little 6000 mah battery pack during the day, which I turn around and charge my phone with at night.   I can usually get 2 full charges out of the battery pack and it takes pretty much all day to charge the battery pack from the solar panel.   I got the Nomad 7 for a pretty decent price but if I did it again, I would get the Anker 15w or even the 20w from amazon.   Both are about $50.00 right now on Amazon which seems to be a better deal than the Goal Zero.   I am pretty sure you are paying a premium for the Goal Zero name.

Thank you for your input and honest assessment of the Goal Zero Nomad. I feel confident with my choice of the Anker 21W panel.

Just took delivery of the 15W Anker solar panel yesterday, but have not had a chance to use it yet. 

But upon visual inspection, the solar panel looks pretty sturdy and well made. It is pretty lightweight. The 550 cord loops also seem to be pretty stout. Only reservation is the "pouch" that holds the power hub only has small patch of hook-and-loop in the middle, so anything placed in the pouch can potentially have an unscheduled exit. This is a potential concern as I plan on attaching the panel to the back of my backpack while hiking, and when attached with the pouch folded behind the panel (between the 2x solar panels and backpack) the opening is facing downwards (partly due to the locations that the 550 cord loops are attached). 

May have to Shoe-Goo some more hook-and-loop in there, or find another solution with shock cord or additional 550 cord to increase attachment options/flexibility.

Let us know how that works out.   I looked at one a while back that someone else had (I didn't know him), and it looked fairly nice.   I would like to hear how well it charges.

...and life expectancy.
