Update: Both Powerbanks and USB chargers are gone. There are just the USB cables remaining.
As I tend to visit the US a few times per year I've ended up being a bit of a mule for GZ users when it comes to bringing back goods, particularly Anker stuff. From my trip there last month I have a few products left over as I ordered extras -
2 x Anker Powercore Speed USB-C 10,000 $NZ45 each <- all sold
2 x Anker Powerport+6 USB charger USB 3.0 x1 + regular USB x5 NZ$50 each <- all sold
1 x Misc Anker USB cables 1x 1ft, 3 x 3ft and 1x6ft NZ$23
Shipping is $5.50 per item in a standard NZ post bag - if you wanted multiple I would probably need a slightly more expensive bag. Courier is extra $3 or $6 extra for courier + signature required.
Powerport only comes with the US cable. These are standard figure 8 cables so are readily available - I can supply a NZ cable with the charger if you want for an additional $4.50
