Owner Reviews, Ratings, Comments and Criticism
This is a great product. It is perfect in (almost) every way. Smallest 150 watt inverter around. Very quiet. Works both in the car and on a plane. Has both a 3-prong AC and USB powerpoints. It shines particularly well verses the 'big-black' inverters for traveling for 3 reasons. 1) Again, it is so quiet that more often than not you can't even hear it; 2) when you re-start the ignition on your car it properly resets itself and keeps providing power (unlike the 'big-black' units which are universally dumb and unpower themselves); 3) if your car's battery voltage drops (because it is cold...older battery...or you are not running the engine) this unit tends to keep working whereas most others sense the voltage drop and quit working. The only minor quirk with it is that the silver-tipped spring that you insert into the lighter socket is overly sprung and in some cars you need to occasionally re-push it into the lighter. An annoyance but not a deal breaker. Overall I cannot recommend this enough. The only other unit that comes close is the Xantrex 175 watt unit (#813-0291). It has all of the above qualities except that the airline portion of the adapter would not seperate correctly from the cigarette portion of its cord. This resulted in the unit's tip being slightly loose at the plastic seem of the cigarette portion of the adapter.
