I always wanted to get the thecoopidea 10.6A Power Block but just no impulse to buy it. The Coop Idea was co-founded by two friends who grew up in New Zealand who currently resides in Hong Kong.
The recommended retail price (RRP) of the thecoopidea 10.6A Power Block is S$99, however MobyShop is selling it for S$79.90. That is the cheapest I could find till I went to Sitex 2014 and saw it being sold at S$79 at Nubox booth.
DK and I bought it and we were surprised that we got an additional 10% discount if we bought two together. We ended up paying S$71.10 for it. I seriously doubt you can get any cheaper than that in Singapore.
The thecoopidea 10.6A Power Block is a 5-port USB charger capable of outputting a total of 10.6A (4x 2.4A port and 1x 1.0A port). That means that you can charge four iPads and an iPhone together at the same time. This is great for travel because you just have to bring one charger and it can charge almost all the devices that your family have when travelling.
There are two Smart USB ports out of the five USB ports, one for the 2.4A and one for the 1.0A. The Smart USB ports contain a built-in smart chip that auto-detects the connected device and provides a suitable charging solution by adjusting the way of power supply and charging current.
It comes in three colors, Yellow, Grey and Blue. I bought the Yellow and DK bought the Grey.
It measures 88 x 75 x 33 (mm) and weighs 210g.
