Bought a typical red laser "pointer" from Ebay, because I didn't have one. Received it promptly, but there is something (more than usual) wrong with the junk 18650 battery or charger.
When plugged in, the single cell charger glows a steady green. When the battery is installed, the charger light begins to steadily flash red. When I replace the battery with another know "good" 18650, the charger continues to flash red, so whatever is going on seems to involve the charger rather than the batteries.
I have the charger plugged into a Kill-a-watt doo hickey, and it doesn't seem to use any current. The only functioning charger I have show that the charger cycles on for a fraction of an amp every 10 seconds or so.
Any suggestions besides the obvious, throw it away?
