    Default Off "GRID" (Wilderness) Solar battery charger system (Small) Need advice.

    I need advise on a small portable (Backpack-able) SOLAR charging system for charging an "Internal Li-ion battery in the wilderness.


    I am considering buying a product with this battery information: (And sadly I know zero about this subject)

    Battery Life: Over 4 Hours
    Battery Type: Internal Li-ion
    Battery Charging: Standard USB interface with included wall charger
    External Battery Pack: Compatible, not included

    I have a small goal zero charger that works well and a brunton solar roll that is even better. I love them both.

    I use the goal zero as well and have had nothing but good results with it....except on cloudy days, but you really can't expect solar chargers to work on cloudy days. You can get them pretty cheap on ebay.

    For a relatively simple and light set-up give this one a try. The panel works well and is pretty durable, i've hung it from the outside of my pack while walking for charging on the move and have not had any durability issues. It charges AA's and AAA's pretty quickly. The guide 10 battery pack also has the advantage of having pre-charged batteries ready(you can plug it in to a normal USB at home). So when you need batteries, you can just swap your drained ones with ones that are ready to go. It folds flat, it's not the roll-up type, but i've found it works better than the roll-up type and charges quicker.

    This may help: http://www.outdoorgearlab.com/Solar-Charger-Reviews

    It could be useful to know the amp-hour rating of the battery to get a better sense of how much or little of a charger you need. The monocrystalline solar cell technology is much more efficient than the polycrystalline or amorphous silicon. Depending on how much juice you need and how likely sunshine will be, you might also consider a lithium ion jump starter pack like this.

    I have this same one for about 3 yrs. It had an issue charging last week so I emailed them about the problem and they asked I send it to them and they would send out a new one free of charge. Customer service seems pretty good we'll see how quick the new one arrives.

    Pair up a Goal Zero set with a "bio-lite" a chaarger that works by having a fire built to get a charge.

    Winters short days and long nights and a fire is pretty handy anyways, for all sortsa stuff...

    Just sayin'....http://www.amazon.com/BioLite-BL-CSA.../dp/B00BQHET9O
    If you can't Kill it with a 30-06, you should Hide.

    What is it about the Brunton that makes it better in your view?
