Anyone who does long trips and carries kids in the back of a car that doesn't come with its own AC power outlet should find this product useful. Amazon's Pocket(?) Power Inverter is one of those little gizmos you didn't know you were missing until you start using one and maybe not even then. It will provide up 120V AC and supply up to 130W if plugged into the cigarette lighter (cable included), up to 175W if attached directly to your car's battery with the provided battery clip cable.I only tested the cigarette lighter option because I can't imagine myself ever connecting anything to my car's battery for the purpose of drawing power. When plugged into the cigarette lighter, it powered a portable DVD player via the AC port while charging a Kindle through the USB port, thus proving its worth. While it won't shut down under non-optimal conditions, a blinking LED does alert you when the battery voltage drops below 10.5V, then the Inverter itself overheats or when the attached device attempts to draw more than 175W.My test drive (literally) revealed the following - I will prefix the positives with a '+' and the negatives with a '-'+ Small size - true, it would fit in a pocket without cables but I can't see why anyone would ever want to carry this in their pockets.+ Cables included, both the cigarette lighter and the battery clip cable and they are both long enough to be useful.+ Setup is quick and simple.+ Manual explains and illustrate the setup.+ Amazon's backing, including a 1 year warranty and Amazon's return policies and support are the best in the known Universe.- According to the manual (didn't happen while I was testing it) it does NOT shut itself down when overheated, when the battery output drops or when the attached device demands too much power.- Not exactly an elegant solution - our DVD player had its own AC/DC converter and we ended up with lots of wires and little gizmos on the back seats.- No carrying case or pouch makes it easy to misplace the cables. Does Amazon really believes that we are going to keep this in our pockets?I am going to rate Amazon's Inverter as a 4 stars (I like it but I don't love it). It's a good product but no little gadget that doesn't come with a case or a pouch to store 'it' and its accessories will ever deserve or get 5 stars.
