LG Motion 4G: External battery cases?

murph07002

I know the iPhones and Samsung Galaxy S3s have external battery cases, like the Mophie Juice Pack (iPhone) that doubles the use time of their phone.

Is there any known CASES that can do this for LG Motion?

Not Superman

Yes course like the Onite.

Which External Battery should i go for. I'm confused, trapped decision: X? My intention was 30000maH battery back ofc… But after i saw this 10400mah features i'm baffled… And ye kinda pricey but tough choice… Look at the safety in this https://deals.iphone… L-battery-brown and this was my first intention… https://deals.iphone… Ah-battery-pack but after that 10400mah pack details… I'm baffledd…
Sound coming from my external iPhone battery? This may seem like an awkward question, but since when did batteries make a whirring sound? It's not like they have movable parts inside like a hard drive. I'll post the link to the exact external battery later.
Is there an iPhone 4/4s case where you could snap on and attach an external battery? IIm looking for an iPhone 4/4s case where you could simply snap on the battery when you need it, and when the phone is charged up, you take it off and put it away so the phone isn't bulky all the time. Or at least a power bank that hangs on the back of the phone and charges. IIm looking for something at least 1900mAh and under $25.
IPhone 4s- What external battery will work with my Otterbox case? I have an iPhone 4s with the Otterbox Defender, and really need an external battery. Like the Mophie Juice Pack Reserve. I don't think that it will fit with my Otterbox, so does anybody have any ideas of what battery to get so I can continue to use my case?
