Might want to note that they're refurbished models.
Not saying it's a deal breaker just cover all the bases
@nerdpov I got one of these (http://richardsolo.com/richardsolo1800withcable.aspx#.UCFYbU4gfSg) like a year ago and it is pretty good. Still works great (used it last week).
I still prefer my Mophie case for day to day business as I have to use it every day but this thing comes in handy when I'm out of town. Charges my laptop for a bit and has kept my crappy 3DS from dying while on a plane.
You can find a coupon online that will work with this as well. I paid like $25 bucks when I bought it from them with an online coupon I got from using the google. That savings is their everyday price despite the advertisement for what it's worth.
