E-POLAR 300W Car Power Inverter Review – Pure Sine Wave Inverter

This product is quite new, so it lacks so many reviews. Since I write reviews on the comments posted by the users, it is a bit difficult to find many comments to write E-POLAR 300W Car Power Inverter Review. Anyway, I will try to give as much information as possible to help you decide whether this is a buyable power inverter or not.

First of all, E-POLAR 300W Car Power Inverter is advertised as an inverter that features a fast charging 60W PD port, which is a good feature in this inverter as anybody wants to charge their devices fast.

Second, it is a pure sine wave inverter, which is another advantage of buying this unit if it worked reliably. Of course, pure sine wave inverter is far better than a modified sine wave inverter in my view. The manufacturer has shown a picture depicting the difference between the pure sine wave and modified sine wave. By seeing the picture, you can know that pure sine wave is more reliable and smoother than modified sine wave, which is the main difference.

Lastly, the ePolar pure sine wave inverter is very good to deliver reliable and smooth electricity to the connected devices. You would be able to run your sensitive devices without a problem. Well, there is a wide range of sensitive electronics which are used in our day-to-day life. These devices can be mobile phones, laptops, medical devices, laser printers and more. Additionally, the E-Polar 300W inverter can be used to charge 5 devices simultaneously. Yes, it has connection sockets such as 2 x 110V AC sockets, 2 x USB ports and 1 x USB-C port.

Both Happy and Unhappy Users

A disappointed user said that based on some reviews he thought that it was a good inverter. He was very positive to this unit but he was disappointed from the performance. As per this user, the main problem was that it powered off for unknown reasons, the user has to press the power button many times to power it on again. Also, he said that it was advertised to provide alligator clips but the E-POLAR 300W car power inverter came without the alligator clips.

A happy user said that he was a bit worried about it being overpowered but it was a nice car inverter. As per this user, he has to work in his car, so he needed to operate a laptop in his car. So, this E-Polar inverter worked for h is purpose. However, he didn’t use this product for a long time, so he couldn’t say more about this product.

Please look at the features of the E-Polar 300-watt inverter. I see it has limited features. It lacks some of the important features as well. However, if you want to buy this low-price power inverter, you need to know the features at least. It has just 300W output capacity, so it is only good for small devices.

PROS

  • It is good for a car to charge small devices.
  • A handy unit
  • Seems a well made product
  • The plugs fit tightly.
  • All the connection ports function well.
  • Pure sine wave unit

CONS

  • It switches off without a reason.
  • Some users didn’t get the alligator clips but they are shown in the picture.

The key pros and cons are written above. These pros and cons are an important part of the E-POLAR 300W Car Power Inverter Review. I can classify this E-Polar inverter as an average quality inverter because the E-Polar brand seems like a new Chinese brand, so it didn’t attract many customers as of now. If you want to buy this 300W car power inverter, please research more in this unit before you buy it. Yes, it looks very good and stylish, and it is a great handy unit, that can be used to connect with your car battery using the provided cigarette lighter plug. The main benefit of buying this unit is buying a pure sine wave inverter, which is very good for charging sensitive electronics.

Product Description

BESTEK 300W 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

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 300W.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 300 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 300W Pure Sine Inverter,1xUser Manual,2xbattery clamps cable,1x 12V cigarette Lighter plug cable,2 x spare fuses.
