The IonBank 5k has a battery capacity of 5,000mAh and has two integrated cables, one of them is either the Lightning or Micro USB cable and the other is a normal USB cable to charge the battery pack. It also has a spare USB port to charge another USB device.
Ignore the long product name, it is basically a 9-port USB 3.0 powered hub with an additional USB charging port. Technically you can use all the 9 ports for charging as well but they might not be enough current because each of the 9 port can output a maximum of 900mA. From the USB 3.0 specifications, 900mA is the maximum amount of current that can be output from a USB 3.0 port.
In my blog post about Panasonic Mobile Booster QE-QL101 last year, I did mention about the large capacity portable battery from Panasonic which has a capacity of 10,260mAh. I did not manage to find that in Singapore. Instead, I saw it in Thailand and I bought it for TH฿3,990 (S$160.40), and after a 7% VAT refund, it cost about S$150.
Don’t let its massive physical appearance deceive you. It is pretty light weighing at 490g. It is slim as well, and the thickness is almost the same as a standard USB port.
Twelve South PlugBug World was announced beginning this year and I have no idea why is it not selling in Singapore yet, not even the Apple Online Store in Singapore.
When Li Xiang went to Hong Kong last week, she bought it for me from the Apple Store in IFC Mall, Hong Kong. It is retailing for HK$348 (S$60). Li Xiang also mentioned that the Twelve South PlugBug World is not displayed on the shelves and you might need to request the store assistant to get it from their storeroom.
I have been eying on the Griffin PowerDock 5 since it was announced back in January 2013. But unfortunately it wasn’t released till last month (July 2013).
The Griffin PowerDock 5 is retailing for US$99 (S$126) directly from Griffin’s website. I doubt it will come to Singapore anytime soon. Griffin offers free shipping within the US and they do ship to Singapore directly and for the PowerDock 5, the cheapest shipping is about US$12 (S$15.30) without tracking. But I did not choose that option, instead I shipped it to HopShopGo, which is a freight forwarder and paid US$20.08 (S$25.50) for DHL Express shipping to Singapore.
It has an output of 4A, but unfortunately it is shared with the 6 USB ports, I wish it says what is the maximum output per USB port. But nevertheless, I still think it is a pretty useful charger to have if you have plenty of USB devices to charge.
The Innergie PocketCell Duo was showcased at CES 2013 back in January 2013. It is the successor to the Innergie PocketCell which is retailing in Singapore for S$79.
The Innergie PocketCell Duo is a very light portable battery charger weighing 132.5g and has a capacity of 6,800mAh. It is capable of outputting 2.1A for each USB port. This makes charging high capacity devices like the iPad, iPad Mini, Samsung Galaxy Tab and Samsung Galaxy Note 2 faster than most portable battery chargers. You can even charge 2 iPad at that same time without compromising the charging speed.
