Philips Surge Wall Plug with 2 USB Charger 2.1Amps @ Dick Smith
Found this for $10 in-store in DSE Botany today, down from regular price of $39.98. Plenty in-stock around Auckland apparently.
Same as this deal as this Ozbargain post except ours are cheaper for once thanks to exchange rates!!
P.S. sorry for poor quality photo, need a new phone and don't carry my DSLR with me all the time haha.
Still plenty in stock at the following location:
Takapuna, Onehunga, Sylvia Park, Britomart.
Few left @ Queen St and Botany (need to check).
For anyone wondering these are 2.1A charging ports. However, i can't find info about whether thats shared - a lot of devices like these share a total current across both ports.
