These are a dual usb output, both ports are 2.4a. Originally $44.95 in DS (no wonder they didn't sell), Then went down and down as we got towards the end, now listed on the site @ $2.25 but ringing up at the register as $1.50 at DS Mentone. I have been looking for these, next best deal I could find for 2x2.4a was Jaycar @ $15, i.e. 10 times the price.
8"and 10" Move Tablet cases, lotsa colours, $2 each.
Retractable usb cables, $0.50, usb to iConnectors also $0.50.
Can't say what stock is elsewhere but these are useful things at rock bottom prices.
I bought one during the Dec sales for 5 bucks.
charges well, but it's quite small. good if u leave it in the port long term, but difficult to remove if u change cars often. or just buy 2!
