Met up with the local distributor of MiLi where they showed me their whole line of extended battery packs for all things made by Apple, including the new iPhone 4 and the iPad.
I borrowed this one (the MiLi Power Spring 4) which is specifically made for the iPhone 4. It looks like a regular casing, though a bit thick, that doubles as a 1600mAh battery charger (adds up to about 80% additional battery life of a fully charged iPhone).
They have ones for the 3G and 3GS as well as for the iPod 2G and up but I think external battery packs are more important for the iPhone since their batteries drain much faster. All battery packs come with a light indicator so you know how much battery life is left on the unit (you charge it back via a micro-USB cable that comes with it).
If you don’t own an iPhone but is still looking for a more practical and portable battery pack for your smartphones, the MiLi Power Miracle supports quite a number of handsets.
The Power Miracle comes with 6 adapters for Nokia, LG, Samsung, iPhone as well a mini-USB and micro-USB ports. The battery pack is rated at 2000mAh (around 130% to 150% more battery life) and charges via mini-USB.
To complete the line, MiLi also has a couple of fancy universal chargers and pocket-sized USB chargers.
Here’s the complete price list of the items above:
Power Spring 4: Php3,200
