Solar Array

Wondrous item, rare

This sharp-cornered metal box is 5 ft. by 1 ft. by 1 ft. It comes with a key that is necessary to unlock it (it can also be unlocked with a DC 25 Dexterity check using thieves’ tools). Once unlocked the box unfolds into a 10 ft. square of paneling that is metal on the underside but a glassy black on the top side with intricate traceries of metal filaments visible just beneath the surface. The array has a power cable and a port for plugging in batteries. Only the port or the power cable may be in use at any one time. When the array is opened and placed in full sunlight, indicator lights adjacent to the port and the cable glow green. A battery or any item that uses batteries can be plugged in to the solar array via the port or the cable and will gain one charge every 4 hours. If the connection is broken partway through a 4 hour period, the partial charge is lost. If there is indirect sunlight or overcast the Solar Array provide one charge every 12 hours instead.
