BESTEK 500W Car Vehicle Power Inverter DC 12V to AC 230V 240V Converter Car Charger Lighter Adapter with Dual USB Ports

Great product that I'm using to run a mix of flourescent and (mains powered) led lights in remote stables using solar power and a battery. The load is currently only 170 watts but the spare capacity allows for expansion of the lights and other uses. I still need to check the current being drawn if the unit is left on when not in use but, contrary to what I have read, I would highlight that the cooling fan doesn't run all the time if there is no load. As my lights are switched via a light switch then if the lights are off then the fan stays off and comes on as soon as I switch the lights on. The load can be applied while the invertor is switched on, it just goes through a slow start-up which is not noticeable other than the led on the invertor goes from red to green. I did run my battery down at one point and found that the unit had it's one LED on probably indicating a battery undervoltage.The unit seems to be of good quality although I did note that the neutral terminal on my invertor turns slightly so I assume is not tightened correctly within the invertor but it's working okay and I didn't want to take the unit apart to investigate.I would also point out that if you plan to draw the 600W that the invertor can supply.then you will need good sized cables for this to minimise power loss, I used 16mm cable as I needed a 1.5 metre run from the battery. With a 600W load you will be drawing 50amps from your 12volt battery and the supplied cables looked rather thin for this. You should also note that you won't get very long operation at this load from a 100Ah battery and more importantly you'll need a good set of solar panels to keep the battery charged in winter when you need lights the most.I have not used this to power any motors such as fans as you will see from other reviews that this is NOT a pure sine wave generator (ie like our mains power) , but a modified sine wave wave (basically a square wave) and so motors may tend to run hot.

Great to have in the car to run laptops etc. I run it off the 12V socket when driving. Sometimes needs to 'warm' up a little after plugging in before the green light will come on and start supplying 240V. I suppose this is to do with the transformer. Works well though. Allows my wife to use the laptop on long journeys using the smartphone as a hotspot.Great when camping if you have an old caravan or a soalr panel and you must have 240V socket.

What an awesome sleek product this is. As soon as you look at its manufacture, you know immediately you feel safe, and very well protected with its triple fuses. What makes the inverter so very practical are the enclosed cables, one for the cigar lighter, and the other to connect to a battery. I have been using inverters since they become fashionable about ten years ago. I've had many and still got a couple of them. But this BESTEK 600W inverter has to be the best purchase I have made. I use them for charging wheelchairs, laptops, and I always carry one in my car. It has become my survival tool. And in this era of gadgets, rechargeable gadgets, anything that requires constant power, the inverter is essential. The product arrived promptly, well packaged and my communication with the company - I wanted a VAT document, was unsurpassable. So all in all, a great product and being sold by a great company. And no, I bought this product. It wasn't free, so that didn't sway my judgement. You can't go wrong with this, but if you do, then you've got an inverter.

Not impressed. Did not work when even a low wattage appliance was plugged into it. Returned and full refund given.

Bought this off Amazon Warehouse so it represented even better value for money. It appears well made, sturdy and comes equipped with both jump and cigarette type leads plus spare fuses although I have only used and plan on using the former. It also has a couple of usb ports. Compared to the cost of buying a stand alone power supply I got this item and a suitable 12V battery for less than £100, a good quality equivalent portable power station would be at least four to five times that amount and I already have a couple of good quality trickle chargers for use with other leisure batteries which also kept the cost down.

Runs almost silently, easily mounted on any wooden surface and works as expected.A little smaller than I thought it would be but that is a bonus in a Campervan

I bought this to use in a show van to light up a few table lights . Due to the fact that I will only be using it for lights I decided that the less expensive 500 watts “non sine wave” would be fine for me. I am using a four foot extension lead and plug the lights into and It works well . I am using 3-4 watt led lamps in each of the lights and the inverter is performing as it should and lighting up the back of my showroom van . It feels sturdy and well built the 13 amp plug socket feels solid As does the cigarette socket too. Overall it feels like a good purchase and I would recommend it.

Item arrived on time. Looked forward to unpacking it. Looked and felt really sturdy, could hardly wait to try it out.Used via the lighter socket in my car.Got the green light, so far so good. Connected a 9v drill to unit, pressed the drill trigger and blew the fuse that works the door mirrors,plus the lighter socket. Tried it straight from the battery to confirm it was faulty, fan runs but no power output.Really disappointed. Was looking forward to using it on my narrowboat and replace the 350w i use at the moment, which struggles to cope.When informed, Amazon dealt with the prob immediately. Returned item and got a refund.
