Arrived bubble wrapped in a small priority shipping box; not a retail package. This is a 1 piece unit, no accessories and a single half sheet of instructions. No loose parts to worry about, the plug is permanently attached and plugs directly into cig adapter. I like the compact size and feel of this unit. The cord is about the right length for me, there is 22" of wire between the plug and the unit. It'll reach the passenger seat just fine from the console. Mine works and produces modified AC power which runs my gadgets nicely (chargers: both USB and AC wall warts). The included USB ports are a bonus. My biggest disappointment is that the fan remains on continuously. This means I'll only be able to use it in situations where the car is running. I had hoped the fan would only turn on when it needed to cool down.

Due to the inefficiencies of a continuous fan, this unit is not a reasonable choice in an off grid battery situation. It is fine in a running car. I bought this unit hoping I could use it in a camping kit but it would quickly drain my solar charged portable battery system (only 9Ah). I'm going to keep it, but it's less useful than I had hoped. I won't be unable to leave this unit turned on when I'm away from the car or it'll drain the car battery, which is unacceptable.

The sales info says "Temperature controlled cooling fan" which tells me the fan should not be on unless it needs to cool the unit. I've contacted the seller to see how we'll resolve this. Perhaps I have a bad unit? *** Update from seller, this unit is working as designed ***

3 stars for delivering the power and having a USB port, but not more due to the noise and waste of energy a full time cooling fan causes. If the fan only went on as needed this would be a nice 5 star Inverter.

*** Update ***

Contacted seller, after a couple of email exchanges it was determined that this unit will keep the fan on at all times. While the unit differs from how I understood the listing, it's not worth my time to send it back. When I ordered mine, 1/3rd of the price was paid in shipping fees, so I'll keep this unit as an in-car unit and look to find something else that will be more efficient in a solar/battery based system.

If your intended use is in a car, the fan is most likely not a problem. You can also check to see if your Cig adapter shuts off when you turn off your keys, then it's even less of an issue as it won't drain your batteries when you leave your car. I have a Cig adapter in the trunk I use to power/charge things on trips and when traveling, mine turns off with the key so I can use this in the car without worry.

Mine continues to work well and has survived weeks in my trunk in the hot AZ sun.

*** For comparison purposes I have also reviewed the GoPower 175w inverter and compare that unit with this one side by side. You will find that video here:

I purchased this adapter for my cross country road trip and it has been so useful! We frequently camp and the adapter is perfect for charging phones and cameras. I've used it for my hair straightener and we have used it to inflate our inflatable mattress. HIGHLY recommended. The customer service from this company is fantastic as well.

Product was delivered promptly. Charges my laptop in just over 1 hour. Also used with a multiple outlet power strip to charge 2 Dewalt 18V batteries together. Fan is fairly quiet.

Cons. Cord could be longer.

Overall I can recommend as long as you understand what you are getting. A nice little inverter for the money. The things that might surprise you is the little cooling fan never turns off. Not a super big deal but it does draw a little under half an amp just to run the units cooling fan. Having two USB ports was why I bought it. Watch the video and you will see more about power draw.

I was watching the coverage of the aftermath of hurricane Sandy when the reporter showed a line of people waiting to plug in their personal communication devices in a power strip that the mobile reporting van had generously given them access to, and it occured to me that a simple 12 volt power port (cigarette lighter socket) adapter might be handy in the event of a power failure lasting for more than a day or two. Realizing that everyone in my household has different charging adapters, I thought that maybe I should look for a small inverter where we could all recharge our devices from the 120 volt output of such a device. Now I realize that you can drop a lot of money in a hurry when you start getting into higher output true sinewave inverters and I wasn't really looking to bust my budget, so when I came across this one for 26 bucks I ordered one just for emergencies. I also own a ES5000 12 volt jumper pack which has a power port built in, so I plugged in the BESTEK inverter and my Intertek "KILL A WATT" power monitor and tried out a variety of different devices. Unloaded, the output was 112 volts. Loaded, it rose to 116 voltsboth acceptable. The frequency held rock solid at 59 Hz, again acceptable. I powered everything from a small battery charger (Dremal tool) to my laptop, to a radio/ CD player, to a small 50 watt table lamp. Everything worked as advertised. The fan does run continuously and it does make a fan noise but that doesn't affect what I'm going to use it for. You might want to consider buying a power socket that has alligator clips attached so you can power it from a stand alone battery if necessary. Remember, this is only a 300 watt inverter so check out the amperage draw of what you are going to power up first (volts X amps = watts) i.e. a 300 watt bulb @ 115 volts draws 2.61 amps. So limit your device draw to about 2.5 amps and you will do just fine.
