    Worked great for a bit, maybe 6 months with regular use. Trickle charges everything. No on and off button so no way to restart it.

    It shows in the pics and under the specs that it comes with a carrier pouch and of course there wasn't anything in there.

    Missing Cable

    I thought I was saving $5 by buying an open-box return. The web site said it included all of the original parts, but when I got it home, I discovered it was missing the cable. I then had to return to the store where I was SOLD (not given) the missing cable for $8. If you buy an open-box item, be sure it has all the parts before you leave the store.
