There seems to be an influx of battery cases for the new iPhone 6 models lately, but this Afterburner case seems to be less expensive than most – and they are on discount for a limited time. There’s a model for the iPhone 6 and the iPhone 6 Plus. Each model will contain a 3200mAh lithium-polymer battery for up to 150% extra life for the iPhone’s battery. The Afterburner adds less than half an inch to the height and less than a quarter of an inch to the depth of the iPhone. This case charges with your existing Lightning cable, so you don’t have to keep up with an extra cable. There’s also a built-in kickstand for hands-free viewing. Cult of Mac Deals is offering these cases at up to a 33% discount for the next couple of days. The Afterburner is available in black only for $40 for the iPhone 6 and $44 for the iPhone 6 Plus. Allow 2-3 weeks for delivery.
