PowerSkin are well known for their shock-absorbing smartphone cases. However, they have gone on to add more to the already-amazing Samsung Galaxy S III. The new case from them brags about NFC, added power supply and a portable speaker to top it off. The bonus power derived from this case can last a good 2.83 hours of talk time. The charging is shut off as soon as the phone is fully charged to ensure maximum power savings. The case is dust, shock and drop resistant.
The wireless speaker is available with the case only on orders placed before the 19th. Pick it up for $80 from the official site now!
