Product Description

Color: Silver Panels

The OffGrid Solar Backpack is Voltaic's most versatile bag. The solar pocket is removable and can be attached to other bags or anything else as it charges. Besides charging all your handheld electronics, it has 1,500 cubic inches of storage space, a padded laptop sleeve, integrated phone pouch and plenty of other pockets. Two 2.0 Watt Solar Panels generate power in sunlight. They are waterproof, lightweight and built to withstand abuse. Universal USB Battery stores power for use anytime and is specially designed to charge efficiently from solar. When not in the sun, the battery can be charged using the USB Power Cable or optional AC travel charger or DC car charger making it just as useful on the grid as off.

Very happy with my purchase! Great quality pack, excellent construction and the solar panels and battery are top quality. my only complaint is it needs more internal space a 15" macbook in neoprene skin only just fits into the rear laptop compartment, and I regularly carry 2 plus other items.

An excellent backpack with attached solar panel. They really have thought of everything including being able to zip off the solar panel and just use separately.

Due to the winter I have not be able to test the solar charging feature. But the backpack fabric quality is terrible!
When I ordered this backpack, I picked the charcoal pennel. But I got an email from the seller telling me that they "accidentally"
shipped the silver pennel. They wanted to know if that is OK or I can wait two extra days and they will ship me the charcoal pennel.
I thought it's not a big deal so I say OK, I'll take the silver one.

Well when I got the backpack, it had a small wear near the pennel zipper that made it hard to zip an unzip the pennel pocket. I was not
happy but I did not want to deal with returning and reshipping so I let it go. I know, I can not say for sure that they intentionaly sent me
faulty backpack but I am saying I did get a weird feeling in this case. If my subspicion is correct, I think it is extremely unprofessional of
them.

I had not used the backpack until a month ago when I went on a 200km biking trip. On this trip the backpack fabric torned (ripped) in three places.
All near the front pocket. It was not the threading that got ripped. It was the fabric near the threading area the got ripped) Fortunately, I was traveling in an Asian city where they can repair backpack. Thus I had it repaired and it seems fine.
but I have to be very carefull to not load the backpack too much again.

I owned two other non-solar backpacks and I regularly overloaded ( to a much higher degree than I loaded the solar backpack) them for a year now and it never ripped.

It is winter time so I have not fully test the solar charging feature but where I was biking, there considerable sun light and my cell phone
almost completely drain the battery in the backpack. Thus at this point I don't have much confident in the solar charging feature but I will
wait until summer time to test in full direct sunlight and I will give an update.
