Adding Protection and Extending Battery Life in a Thin Case


We can’t live without our phones. That means protection is as important to most users as always having a powered phone when they need it. But can all this be offered in a compact way? With 3Line Power Case it can!


XPNDBLS’ Product Development Process


Our tech experts designed the 3Line Power Case as an extremely lightweight yet protective case for the iPhone 6/6S. Our designers developed the case to offer a built-in, razor- thin battery to keep your iPhone ready when you need it. The 3Line case is the thinnest iPhone battery case available yet still offers an elegant, ergonomic design. Our team used a mix of TPU soft and ABS/PC hard materials to give a high quality, soft touch premium case finish. The mixed plastic materials also allow for a comfort grip while achieving well rounded protection.

In addition to drawing on our design acumen, XPNDBLS power conductivity know-how came into play when we manufactured the built-in battery to disappear smoothly into the inner structure of the case.
