CB123A Battery Charger - 12V 3A Output, 115-230-277V AC Input - Universal Power Adapter for Cars, Motorcycles, Boats & RVs

I've ordered several of these units and they work as advertised. Would give 5 stars but I did receive one that only functioned for a couple of days and died. I recommend using them as soon as possible. Seller would not accept return because it was a few days outside of Amazon's return policy.
