    Bought the inverter to power a 24″ smart TV in my RV and work great. It is easy to assemble and connect the clip cable to battery. Excellent alternative for a power generator when you run out electricity definitely should consider purchasing it !

    We mount the inverter under the hood in most vehicles, it powers up our LED TV and the DVD on a long trip in our RV to watch movies. Works as it should. Very happy chose this inverter over the others.

    Purchased this inverter to use in our travel trailer. It works great! If you are looking for an inverter to convert from battery power for household use, you will love this inverter !

    I wired up 4 deep cycles 12v 185ah batteries in parallel and hooked them up to this inverter for a football tailgate party. We had a 40″ LED TV (~35 watt) with a powered HD antenna to watch the early games. The inverter ran quiet and cool the whole time. After 3 hours, everything was still going strong. No more noisy, smelly generator needed! The whole group was impressed, and random people around us were stopping by to watch. I’m very glad I bought this !

    I probably will not install it for a while since I am involved in upgrading a recently purchased RV. It was delivered on time and in good condition. It appears to be well constructed. I purchased it based on the mostly favorable user reviews.

    So far so good. Very quiet, and was easy to install. Wish the included wiring was longer, just went to the auto part store and replaced it for longer lengths. Especially since the inverter is down below the trailer. We installed this in our little camper to go boon docking. Just need to hook up our solar panels. So far I have tested out our small 19 in TV and a 250w heater off of a group 31 battery runs both of them with no troubles.

    I purchased this inverter after having bad luck with smaller and poorly made inverters tom power my off grid camp. I just love this inverter. It is larger than I expected but is well-built. I have this attached to 4 12volt batteries charged by one solar panel. The fan has never come on yet. I run a small fan, small TV and DVD player, and 2 lamps with LED lights.

    As we could not find a generator to be bought pre-hurricane, I bought and used deep charging batteries wired in parallel and using the inverter I could run several lights, three fans, charge multiple iPhones and run three laptop computers. Much less costly than buying a generator.

  10. Jeanie H Rimmer

    Excellent product. Works flawlessly. Includes everything you need. Power cable is too short tho. Has the fuse, and remote start which really make a difference. Use this in a locksmith van.

    This excellent power inverter arrived quickly and worked as promised. Actually, this unit worked better than promised. I’d recommend Magnum’s products to anyone that wants an excellent product at a very competitive price.

    Great quality product. Built to last. Used it for off grid basic needs. With solar power!

  13. Ethel E Agee

    I’ve been using this as backup power for my house connected to an electric car and it works perfectly. 4000W is enough to power my boiler, fridge, and light(s)/TV. The digital wattage output is handy to prevent overloading it as well as having the included fuse for additional security.

  14. Cynthia P Hernandez

    After lots of research and review reading this is the best inverter for the money it comes with an awesome wiring kit and it’s very well-built they also offer a very good warranty and great customer service for the manufacturer !

  15. Dale C Endicott

    Worth every penny. A little larger than I thought it would be, but it does what I need it to do.

  16. Rose I Brookes

    I’m very happy with the unit I received. It is new, so I cannot speak to the durability but it looks well-made and sturdy enough to last a long time. I like the battery level indicator.

  17. Brandon K Crandall

    This is a very high quality inverter. We used it on a long trip in our RV to watch movies on the LED TV. Works as it should. What makes it great though is the sturdy design. I’m very happy I chose this model over the others.

  18. Mary J Anderson

    This product was very easy to install and a very convenient size. It came with the main line fuse and the battery cable which is a huge money saver. I am going to try and use it this weekend for a possible snow storm hoping it will help.

  19. Sheri H Parisien

    Got the inverter on time. It was really easy to install. I just need to buy longer cables, add the ones that came with it were only 3 footers.

    I really like it that the product came with everything necessary for installation. I installed it in our camper to run small appliances when we are in the boonies. Work great so far.
