Yeah, I bought a couple of these, the odd thing about these are that the charge indicator light is on the wall adapter. The light on the battery holder just stays red all the time. When the light on the wall adapter turns green, then the battery is charged, weird…includes 12v car adapter…
I have a few of these from other vendors that came with package deals. They actually have all worked ok so far. Still, I think you get what you pay for, and have since bought a better charger
