    The REI Member Dividend

    The REI dividend is a unique benefit of membership in the REI co-op. It's comprised of your member refund—typically 10% back on eligible purchases—and/or your REI Visa® card rebates.

    Each March, active REI members and REI Visa cardholders who earned a rebate receive a refund in the form of an annual dividend notice.

    Only active members receive annual dividend notices. To maintain your active status as an REI member, you need to make net merchandise or shipping purchases of at least $10 per year, unless you joined that year. Member numbers are issued in one name and only that person receives the member refund. Your number can be used by others in your family, but it cannot be transferred to someone else.

    by fromRafting portable solar panel This is the second one of these that I have bought from REI. I have two GoalZero Sherpa 50's (also bought from REI) for charging laptops and cameras and in good sunlight, these panels recharge the power packs within several hours. At 3+ pounds each, it isn't a problem to carry both of them in a dry box while rafting.

    by fromrecommended for 12 volt Both the guide 10 for AAA and AA and the bolder 15 for my 2 6 volt RV batterys work great. Quick charge times and the Quality shows thru every time.

    by fromCharges our silver bullet Love this to charge the Escape 150 (silver bullet). We daisy chain two Boulder 15's to charge and it takes a long time, even in the long summer days. It takes a lot of sun to completely charge but for the price this system is awesome! Compact, portable, reliable. Love goal zero!

    by fromGreat products. Tha size and out put of the 2 boulder 15's is perfect. The price is a little high. Cons: The connectors are confusing and expensive. The connectors are not compatable With other devices.

    by fromRV/Camping I use four Boulder 15 cells in series to recharge my RV battery every day while camping. I'm getting enough charge current out of it to offset the constant ~1.5 amps being drawn by the appliances, and still put about 2 amps into the battery. The strong construction made it easy to bolt the panels together using hinges. The assembly folds up for easy storage. Also, the tempered glass is strong enough to withstand being hit by a falling pinecone.

    by fromSmall Solar panel I have two of these on the roof to recharge the two 150's I have, takes about 4 days of midwestern partially tree shaded sunny days to fully charge the 150. Sturdy construction, only drawback is I wish it had a longer cord (or Goal Zero sold a longer extension cord than 6 ft)

    by fromGreat Product I used the panel while on a month-long road trip. Mounted it inside my car on the dash and it worked great. Only downfall was how slowly it charged if it was very cloudy or stormy. Otherwise, it worked fine. Definitely recommend it.
