Review on 🔌 Convert 110V to 12V – Cellet Universal AC/DC Power Converter Adapter (2.0A Output) for Car Cigarette Lighter Port by Gary Newman

It works well although you know what you can and can't connect to it. It only supplies 1A of current, so it's really only good for charging a cell phone, GPS device, etc. It doesn't even work with my electric coffee thermos - as soon as the heating element turns on, my thermos turns off. because he apparently tried to draw more than 1A. Don't expect this to work for tire inflation, air compressors, etc. anything that uses a lot of power. (There are other converters for high current devices). But for things like charging cell phones and GPS devices, it should work just fine. Note: The packaging and product description says 1000 mAh, but it should be 1000 mA (or 1 A). The unit mAh or milliampere hour is a unit of energy consumption - for example cell phone batteries are measured in mAh. Basically it's a matter of how long it can sustain a given current - for example a 1A device can expect to run for 1 hour on a 1000mAh (1Ah) battery. A (ampere) is a measure of current. This converter can power devices that draw 1000mA or less. The battery is not 1000 mAh.
