GREANTECK 4000 Watt Modified Sine Wave Inverter Review

Please read GREANTECK 4000 Watt Modified Sine Wave Inverter Review, if you want to buy from a new brand. Yes, GREANTECK seems a new Chinese brand. There are both pros and cons of buying a new brand product. The main pro is that a new brand product often sells at a low price. And, the main con is that you can’t know about the performance as the product lacks users’ reviews.

Personally, I feel that it is a good 4000W power inverter, which can be used in vehicles like cars, RVs, boats and more. I read some reviews and found that it was not so bad. It would pay more than what you pay for it.

GREANTECK 4000W power inverter review

View on Amazon

Well, the manufacturer says that the GREANTECK 4000W inverter is a powerful and stable inverter that is designed very well. It would work with almost all types of batteries like GEL, LifePO4, Lead, Acid and more. As per the manufacturer, every component is made with precision keeping quality in mind.

The GREANTECK 4000W inverter is full of features that you need for a convenient operation. It has numerous connection outlets such as 4 AC outlets, 2 USB ports, 1 USB-C port, and it comes with a wireless remote control. The 12V inverter comes with some accessories like fuses, earth wires and wrench.

More importantly, the 12v GREANTECK 4000W inverter is highly protective as it has almost all the protection features. Therefore, the vehicle inverter would surely provide protection against over-heat, short-circuit, under/over-voltage, over-load and other faults. Also, the inverter is designed keeping user friendliness in mind and has sound alert and automatic restart functions.

A Powerful 4000W Inverter

I read review posted buy a user on Amazon. He said that he used this inverter for RV box conversion. The user is able to run a heavy-duty vacuum cleaner, 1000W microwave and a gas dryer without a problem. He said that he was using a 300Ah lithium solar battery, so he was hopeful that it would run a medium-size refrigerator as well. Finally, he recommended this GREANTECK 4000W unit to others with low budget.

Another user said that it was a great inverter for emergency or off-grid use. As per some users, this inverter works well but it may not be a good inverter for some devices because it is a modified sine wave inverter. However, the GREANTECK 4000W inverter was a good deal for most of the users. It comes with everything you need. Please note that the cables are a bit short but these cables may work in most of the circumstances. The main advantage is the multiple connection ports, so you would be able to connect multiple devices simultaneously.

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

The Sine Wave Inverter has well placed thermal protection sensors,The aluminum alloy casing with a few ripples,Unique vents and also a built-in FAN which comes ON under NO any loads or when the Inverter becomes Hot Once Powerred. It has 2 x 40 amp/32V external replaceable fuse for protection when hooked up to your battery,readily accessible/replaceable from the back of the Inverter;when hooked to cigarette lighter it will use 15 amp fuse designated to your car.

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.
