I don’t fully understand the readings but if you know something let me know. I’m only consuming .36 amps but i’m putting back .63 amps, some might say that is overunity but who knows? Both batteries started off around 12.40 volts each so the run battery is 12.40 * .36 = 4.464 watts while the charge battery is at 12.40 * .63 = 7.812 watts. Thats a 3.348 watt gain.
Try this experiment at your own risk, i only put this video up for information purposes only.

The Washi Paper Solar Power Cat is a unique solar toy and a work of fine art from Japan. Made of exquisite, traditionally crafted washi paper, the look and feel of the Washi Cat is warm, natural and lovely. When light is allowed to reach the solar panel at the rear base of the Washi Cat, its tail will wag. Like the popular Lucky Cat talisman, the Solar Power Motion Washi Paper Cat is a bearer of good fortune and cheer.
