Night Vision

[steo]

This clever design Zenit NV uses a piezoelectric transducer as a power source so you never have batteries to replace. I've used it a couple times and it's amazing. I'll ship USPS priority with tracking and delivery confirmation anywhere in the U.S. for $sold.

How long does a charge last? I assume you crank or compress something a few dozen times right?

To charge it, you pump the lever on the top about ten times and it lasts several minutes until you have to pump it again. It's very quite and easy to do.
