They advertise a 4-5 oz. "puck" that contains a magnesium "power cell" which is activated by adding salt water.
Claim it'll charge six 1,000mAh AA batteries in several hours and continue to do so 20 times, charging 120 batteries in total before the cell is depleted... so they're claiming around 144 watt hours in total for say 5 ounces of puck...
Anyone with knowledgeable opinions, or specific knowledge?
