RoyPow Voltage Converter AC 240V to DC 12V 10A Power Adapter 120W (Max 150W) Car Cigarette Lighter Socket Transformer Mains

I've been trawling the Internet for some considerable time to find a power converter that is capable of powering my air compressor. After much browsing, I came across this product. To the best of my knowledge, at this size, this is the only AC to DC converter that is powerful enough to supply 120W (150W max) power at 10A. The female lighter socket can also be used to power air compressors, car refrigerators, car cleaners, tyre inflators and other DC appliances. I purchased the Ring RAC900 Heavy Duty Tyre Inflator. This is a fantastic little compressor which is capable of inflating any size car tyre including truck tyres in very little time. It is available on Amazon, refer to link: [...] The only issue is that the compressor will only work when it is hooked-up directly to the car battery. It will not work via standard car cigarette lighter socket. A regular car socket cannot deliver enough current to power the compressor for continuous operation. After purchasing the RoyPow power converter I also bought a cigarette lighter socket extension cable which was rated to 15A i.e. the maximum power of the converter. The extension cable is also available on Amazon, link: [...] At this point I had all the necessary tools to do the modification. I hard wired a set of cables from the compressor 12v battery clips to the car socket cable so that the compressor could be powered via standard 3 pin home plug. It worked a treat. Now I can use my compressor for inflating air beds, swimming pools etc directly from a wall socket using my existing heavy duty air compressor. I purchased this item at full price. If the product is unworthy of a good review, I think it is unfair to leave positive feedback as this can mislead potential buyers. I hope you found the review helpful. [...]

Finally..... an AC/DC power adapter that will power most vehicle powered devices. In the past year I have bought 2 other adapters. The first was a Kampa which we used to power up an old cooler box. It was adequate for this. But, on our new VW cooler (which we power up indoors when visiting folk, or staying in hotels when we have modifications done to the VW) it was useless. And so, we took the cooler box into a large motorhome/camping showroom and tested out one that would ultimately work. This was an Outwell unit. However, at this dealership we also bought a mini air pump (Coleman Quickpump) primarily to vacuum the storage bags for our camper bedding. Unfortunately, we didn't test this in store. And, as if you couldn't have guessed.... the Outwell unit didn't have the grunt to run the pump (imagine a 1960's car trying to start on a cold morning with a flat battery). In frustration I looked to Amazon and searched rewiews. The RoyPow ticked the boxes. Everything so far has been handled with ease. The vacuum pump sucks like a ........ (couldn't think of an appropriate analogy here). The 12v kettle boils up (eventually) without hesitation. Even after my Amazon purchase, the RoyPow folks have been in email contact in case of problems of use. Well done RoyPow.

brought to bench test my Kenwood MD player. well made transformer with built in fan unit outputs a steady 11 volts @ 10A perfect for car radio testing

I've had this for a while now. Paid for it myself at full price. I got it to because Im lazy and didnt want to pump up my bikes tires on a cold winter night with a hand pump, so it was going to be used with an air compressor. For that purpose it has done it's job flawlessly, and its near silent - in fact you wouldn't even know it had a fan inside it. My neighbours little kids have all asked me to pump up their tires and this little unit has been up to the task for powering my 150psi compressor. As its only been used to power a compressor to pump up bike tires its run times has only been for 2-3 minutes maximum. Overall its a great unit, a little pricey though!

Perfect for the job the unit is quite large and excellent for powering my electric cooler box

It is a little early to say how the unit will perform in the long run but all the signs are promising. It appears to be well made and is fitted with a British plug that is of the standard required by law (always a good sign). I have run the unit only for a few hours powering a portable fridge/freezer that I use in the car. This mains transformer allows me to take the device indoors or in a hotel room when I am away. In my limited tests the unit works well does not get to hot is quiet and powers the cooling device well. I shall be taking the kit to Europe in a few days time if it continues to function as advertised I shall be well pleased, if not look for another review of it by myself. To sum up at the moment I strongly recommend this transformer unit.

I bought this to allow me to check the tyre pressures on my wife's motor scooter without needing to manoeuvre it close to my car to use the compressor. I had tried a cheaper but well reviewed alternative previously, which just didn't work. This is a good quality product, with no loose or dodgy connections. You have two clear lights which show 1) that the unit itself has power and 2) that the device plugged in also has power. That is really useful when trying to troubleshoot problems! It worked perfectly for me.... and means I can now check the scooter tyres in the warm and dry garage!

Bought this for running 12v fridge when hooked up on campsite as my other cheaper 4amp one packed in while away one trip. This works great. Also runs the 12v shower. Not tried it with my air compressor yet but is 10amp so loads of power for what I need it for. Good LED indicators, good length cables both sides, really solid unit with cooling fan. Don't see any problems with this.

This convertor works well. It is rated at 120W and I used it to power up a car vacuum cleaner, rated at 110W. The power provided by the convertor to the vacuum cleaner was more than enough to drive it well. The convertor is a little bulky, but this is understood due to the "relatively high" wattage it is able to provide.
