Enerpak Vault by Unu Category: Battery Pack Works With: iPad, iPhone, any USB device Price: $80
This is the Unu Enerpak Vault. It’s an excellent spare battery pack for any of your portable devices, and it is even powerful enough to almost (almost) charge the thirsty, thirsty Retina iPad.
But what it does the most (apart from get you out of pretty much any charging emergency) is show the amazing difference between the batteries inside out iDevices.
Unu’s Ecopak is about as simple as an iPhone battery case can get. And as this also means that it is thin and light, and that it will work with not only the iPhone 5 but any gadget than charges via USB, that simplicity is perhaps its best feature.
The Ecopak consists of two parts. The thin, snap-on shell-style case, and the. Battery pack itself. Let’s take a look.
LAS VEGAS, CES 2013 – The iPhone has many hardware advantages over the competition, but it sucks at LED alerts. Smartphones like the ones offered by RIM have a dedicated LED that flashes when you get a message; on Android, you can even dictate the pattern of the LED flashes per contact with a staccato rhythm applied on the touchscreen with your index finger.
Your iPhone? Nothing. The LED can flash if you get a message, but it’s messy and unrefined. But that’s where the Endliss Hybrid Battery Case for the iPhone 5 by uNu comes in. It gives the back of your iPhone just as much information to display as the front.
This is the uNu Ex-Era battery case for iPhone 4 and 4S. It offers a degree of flexibility you won’t find in most other battery cases, although that flexibility comes with a drawback – namely that the case doesn’t feel as robust as some of its less flexible rivals. But you can’t have everything, all the time.
