  • BESTEK 500W Pure Sine Wave Car Inverter:Its output waveform is same as the AC power waveform of mains power grid which delivers a smoothly-varying sine wave for sensitive electronics provided by the electric utility.Perfects for off-grid system,Lower THD,Less wear,Strong inductive Loads Capability.It has little interference with radios, communication and precision equipment.It's also recommended by most cordless tool manufacturer that a pure sine wave inverter is used to ensure long battery life
  • This is an inverter converting DC from your car battery to AC for whatever you want to use within its Watt range.It can pull power from the battery through the cigarette lighter plug or directly clamp the alligator battery clips onto the car battery.Plug this into 12v cigarette lighter outlet provides continuous DC to AC power with 2 AC outlets operates any 110v device and 2 USB ports which detects your device automatically to deliver its fastest charge speed up to 2.4 amps per port/4.2 amps max
  • Isolated Voltage Protects Perfectly for your device from Over-voltage,Under-voltage,Overheat,Overload,Reverse Polarity,Short circuit.it will not drain your battery dry because of an under-voltage protection point.The Inverter does automatically sense overload condition and shuts down AC power when the load exceeds 500W.You will need to power Off/On to reset the overload condition indicated by the Flashing Red.The ON-OFF switch only works for the 3-prong plugs.
  • The 12V plug is spring-loaded and fits snugly into the receptacle.You cannot get 500 watts from 12volt cigarette lighter plug,needs alligator clips for car battery. If you're going to be plugging this into car cigarette lighter,you should keep the wattage under 150,since that is what most car fuses are set for.What You Get:1xBESTEK 500W Pure Sine Inverter,1xUser Manual,2xbattery clamps cable,1x 12V cigarette Lighter plug cable,2 x spare fuses.

  • Really clean sine wave, works great so far
Color: 3 Blue Size: 500W
Took it camping to inflate a large mattress and it worked perfectly. No hesitation and the motor ran at full speed with no extra humming or noises you'd get on a modified sine wave inverter. There's a photo attached hooked up to the car battery to do this job. This load is about 190 watts, with whatever spike that happens when the motor starts up. When it first arrived, I tested it with an oscilloscope because I was skeptical of the "pure sine wave" claim on an inverter at this price point. There's two photos attached- the one that looks perfect is this inverter running an LED 110v lamp. The one that looks a little rough around the peaks/valleys is from a 4000W inverter meant to run a house off the grid (costs several thousand dollars)- but it's running an air conditioner, refrigerator, and all the other junk people plug in at home. Still, it goes to show that this little inverter makes a really nice sine wave. This is good because many types of electrical devices don't function well (or they make weird humming noises) with a poorly shaped sine wave (or a square wave like the cheaper ones make). Other tests I tried: - Charging my Macbook worked fine with normal power plug - Connected it to a 50 watt power source to see what it does under overload. When you try to draw more power than your source can supply, it resets until you turn it off and on again then it happily tries again. This is nice because if you run it from a weak battery it won't sit there trying to make 110v and failing miserably, possibly damaging whatever you're trying to run. - Used USB port to charge the Macbook as it can accept power from a normal USB source (obviously it'll charge a lot slower because there's less power available, but still it gets some juice). Worked fine. - Charged a phone from USB, worked fine I read the bad reviews before I bought this inverter. Some of the bad reviews maybe they got a defective unit, but others are almost certainly from improper use (especially the blown fuse ones). Some things to watch out for: - The cigarette lighter or power port on your car will NOT supply 500 watts, I guarantee it unless you've got an electric car or something and even then probably not. My truck has a 20 amp fuse on that circuit and the car in the photo attached has a 15 amp fuse. At 12 volts, that means they can supply 240/180 watts respectively. And that's at the point the fuse blows, not the point you can safely draw power- the car port says "125 watts max" when its fuse blows at 180. So the people mad because this inverter "doesn't work in my car" or "blew a fuse in my car" were simply trying to draw more power from the inverter than the fuse in their car would allow. - Note in the photo above that I connected directly to the battery. If I had plugged this into the 15 amp power port inside the car with the cigarette lighter adapter, it most likely would have blown the fuse. - The power adapter on my laptop says 140 watts, so even plugging that into the inverter using the car's power port *might* blow the fuse if there's a spike on startup. You REALLY need to look at what you're plugging into this thing if you're using it inside the car and see how many watts it uses- then pad that for safety and because the inverter is not 100% efficient at converting DC watts from your battery to AC watts that it outputs. - Like any electronic device, solder joints can break if you drop it so be careful with it. Treat it like a laptop or something else you don't want broken. Broken solder joints will result in intermittent failure or complete failure. Maybe keep it in the box when you're not using it. Things I haven't tried: - drawing a 500W load to see if it really is 500W. I can only verify it supplies about 200W well. - checking how much power it draws when off with no load, or on with no load. I'd like to get around to this because would be nice to know if it needs to be unplugged when not in use. ... show more

  • Great for a project starter
Color: 1 Red Size: 500W
Power inverters aren't anything new, I still have a 100W unit I bought from Radio Shack over 30 years ago. But even with the affordable power stations available today, inverters are still popular and with a few additional parts, allow the project-person to build their own power station for much less money. On a whim, I decided to try my hand at building my own power station, which includes s 27 series battery box, a 24DP battery that has about 50AH, a 50 watt solar panel, some cables, an inexpensive PWM charge controller, and this BESTEK unit. So far this is working well. The BESTEK is fused, and has convenient, easy to manage, large plastic nuts that allow you to fasten the cables to the battery. It is amazingly light, and relatively quiet. All inverters and power stations make a little noise due the their built-in cooling fans. 500 Watts isn't a lot; you aren't going to power a microwave, a/c or heaters. But you can charge batteries, run a few power tools, and several LED lights. So with a build like mine, you could easily add security lights to a barn or shed. Building your own power station with inverters like the BESTEK also gives you the advantage of putting the inverter where you want it without occupying the full space of an all-in-one power station. So if you're adding solar to an old tear-drop or DIY camper, something like this might be a more convenient addition. In addition to a reduced cost, a DIY system with inverters like the BESTEK lets you replace individual elements. The BESTEK unit appears to be well made and nicely finished, no rough edges. Plugs fit securely, and so far I haven't noticed the unit getting very hot. The cable with the cigarette lighter adapter is nice to have, so if you just need a modest amount of 110 volts while traveling or camping, you don't need anything else, just plug it in to your 12V socket and you can charge a laptop. Depending on how long you need it or how big (AH) your battery is, you may want to leave the engine running. If you're just beginning with your DIY power station, remember the rule of them that you need a battery that's about 10% of the AH (amp hours) of the watts of the inverter you plan to use (I.E. a 1000 watt inverter needs a 100 AH battery.) So in my case, my 50 AH battery is perfect for this BESTEK unity. BESTEK has inverters up to 2000 watts, but for those you'd need a 200 AH battery to utilize that much energy. I like this BESTEK unit, and am enjoying my build. I will likely buy a higher watt unit in the future! ... show more

  • Fan ramps up with load/temperature. Nice design.
Color: 1 Red Size: 500W
Great size and as others have mentioned, the unit puts out quality power. Fairly quiet on the phonics front, the fan itself is variable speed (NOT expecting that feature!). I experimentally used this to charge an EcoFlow from my 12v nominal pack (as a rapid charge/test) and it happily ran along at 400W for 2 hours on a 110Ahr LiFePO4 pack. I'm using the battery clamps. Nice clamping force, zero issues hooking on to a power stud. Included cig-plug adapter is decent and shows what limit you can run using it. Great unit and would buy again. ... show more

  • Works with Tesla 15Volt+ battery system
Color: 1 Red Size: 500W
The media could not be loaded. Tested this today and it appears to work with the Tesla. Comparison photo with another model that is 300W pure sine wave that also works with the Tesla. Only two USB A with 2.4A each on this compared with better options on other one. I like the metal body of this model for heat dissipation. Appears to built well on the outside. My research indicates that the Tesla cigarette lighter power plugs are good for up to around 140W max (just looking at other people posting), so I’d say 500W rated capacity is overkill unless you’re going to do something dicey and attach to electrical in another way. ... show more
