"I purchased 2 of these to run my motorhome when
the generator isn't running. They are working well so far. They are
certainly working better than the flooded battery they replaced."
I've used it several times now and am very happy with it, August 3, 2014
"I bought this for an ArkPak. I've used it
several times now and am very happy with it. I was able to run a
Fantastic DC fan (mostly on low but occasionally on medium and high but
running 72 hours straight), recharge a 15" Macbook Pro laptop several
times and charge two iPhones several times. I also used it to top off a
charge in a Goal Zero Lighthouse 250. The output was 12.7 volts to start
and only dropped to 12.3 volts over the 72 hours. I am very pleased
because I was hoping to get a three day weekend's worth of camping out
of it while not dropping the output voltage below 11."
