Model Description

The 936231 is a rugged case which holds an iPad Mini device. The case surrounds the iPad providing protection to the sides & rear. It incorporates a hinged work stand and a battery cavity with a removable door to hold one ND2057 battery pack. The work stand includes moveable hooks which can be used to hang the iPad on a horizontal bar.

The 936231 is supplied in two halves. The iPad mini slides into one half & automatically connects to the lightning connector. The other half is slid onto the iPad and the two halves are screwed together using the included machine screws. The iPad is now encased within the unit and the external Inspired Energy ND2057 battery can be slid into place by removing the sliding battery door.

The external battery powers the iPad via the lightening connector. A hole in the battery door allows the user to see the 5-bar LCD fuel gauge on the ND2057 battery. When this reaches zero, approximately 10 hours of runtime remain on the iPad & this can be monitored using the iPad battery fuel gauge.

The ND2057 battery must be removed for charging - any of the CH range of Inspired Energy desktop chargers may be used. For fleet applications we have a range of multi-bay chargers which can simultaneously charge hundreds of batteries at a time.
