4.0 out of 5 starsSmall and convenient, fan is continuous
By D Taylor on April 1, 2012
Length: 1:56 Mins
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.

I want to be clear that this is a nicely working unit that will be fine in your running car. My initial goal was to find an inverter that would work in a n off the grid battery based situation. Due to the inefficiencies of a continuous fan, this unit is not a reasonable choice in an off grid battery situation. In an off the grid system, you want to minimize your idle power drain.

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 able to leave this unit turned on when I'm away from the car or it'll drain the car battery, which is also unacceptable. You can get around that issue by plugging it into a 12v outlet that is switched on with your car. Note that by going to a unit that provides less watts out I was able to get one that works without a fan running all the time.Read more ›

5.0 out of 5 starsRoad Trip Must-have
By Allie on July 15, 2011

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.

4.0 out of 5 starsGreat Little Inverter with a Loud Fan
By Shou Hamasaki on April 15, 2014

At first I was surprised at how small this inverter is. I was able to tuck it up under the dash where it is hardly noticeable. I tested the outlets. They worked fine to power my MacBook Air in my car. I checked the USB ports to charge two phones at the same time. It provided AC charging notifications on both my Samsung phones at the same time. The SGS4 was in the higher amp USB port and the SGS2 is in the lower amp USB port. But both show fast charging (as if plugged into AC). All this while the laptop was being charged as well. I have a laser printers in my car's mobile office, but I am planning on swapping that out with an ink jet so I can keep this little inverter in my car and not need anything more. The laptop is the main deal.

I read the reviews about the fan being loud. It certainly is noticeably loud. It runs constantly when the inverter is switched on. One interesting thing I noticed is that if you switch off the inverter, it still provides power to the USB ports. So, here is my current set up. Normally, driving around with the inverter switched off, charging my two phones. When I need the MacBook Air, I switch it on. The fan will come on then. I can charge the Air and the two phones at the same time. When I'm done with the Air (not likely to be using it while driving), then I can switch the inverter off and keep charging the two phones. So this ability to keep using the USB ports when the inverter switch (and fan) is off mitigates the fan noise issue some.

4.0 out of 5 starsNice inverter but beware the fan.
By Smith on September 22, 2012

Length: 2:24 Mins
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.

4.0 out of 5 starsBESTEK 300W POWER INVERTER.
By Robert S. on March 1, 2015
Verified Purchase
3-1-15. I just received this inverter a few days ago! The ac outlets work great! I will definitely try it out on my next power outage! The only two things that I don't like are the cigarette lighter plug has the cord directly wired without a fuse and the 40 amp fuse the unit has is inside soldered to it's pc board. (see picture) That will make it hard to replace the fuse. Other than that the inverter is a great price and was shipped to me in 8 days! Update 11-5-16 (Warning) : The two USB plugs stay powered up all the time even if the power button is turned off. That could leave you with a dead car battery if you don't unplug the inverter.

5.0 out of 5 starsAdd this to your bugout bag
By Cisco Kid on November 15, 2012

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 volts- both 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.

Works great! Depending on the size of the plug for your device - sometimes you are only able to plug in 1 thing at a time due to the outlets being side by side.
