Questions & Answers

As soon as I plug my laptop into it, and play music through my laptop, I hear a very bad cyclical sound. There is a way to filter this out, right?

You are (probably) picking up the electomagnetism put off by the inverter through your headphones. Take the inverter away from you and see if that solves the problem. I would advise you to insulate your headphone wire. If that does not work, you might consider trying it with someone else's (ideally You should not use this inverter if your laptop is too cheap or old as it is built with too few capacitors. can hardwire capacitance into the charging cable). You may also be able to detect the lack of a waveform by checking if that's what the product is actually trying to output. Since I haven't tested it on my desktop yet, I haven't tested it on my laptop yet either.

How can I find out the dimensions of this device? Height, width, and depth. ?

They are as follows in centimeters A length of 12 cm is equal to four inches. The length of 72 inches, along with the width of 7 inches. The square root of 80 cm is Four feet, seven inches*br>Height of 7. There are 5 cm in 1 inch. Here is a picture of 77 inches*br>I hope this helps

According to the descriptions and photos here, it has two (2) AC outlets, but some reviews say it has only one (1). Do you know which it is?

Two 110v outlets and two USB ports are provided on the unit that I received. Recently, I took the unit to Texas for a weeklong trip and it worked perfectly.

Does it drain the car battery or does the car have to be running in order for it to be used?

It has been claimed that while you can run it with the car off, there is more to it, because the lower the battery discharged, the more battery chargers are required. It is this process that shortens the life of your automobile I recommend that you only use the inverter while the engine is running if you want your battery to last as long as possible

Road trips are easier with this feature
5/5

I really like it. I was able to use my double electric breast pump and charge our phones at the same time while using the charger on a road trip. It does have a slight hum to it, but we couldn't hear it too much A lot of wear and tear has been put on it, but there are no visible signs of damage. It's something that I'd recommend to my 6 months later, here is the update We love it just as much as we did the day we bought The quick charge base sits in the center console compartment and I do not have to purchase custom quick charge car chargers since we can just plug it in.

This is a very good tool
5/5

This item was purchased for the Christmas parade in our small town when I put up the lights on my Corvette. This unit controlled the lights and the tree mounted on the rear of the car quite efficiently.

Failed in its original form We replace parts under warranty
4/5

I will eventually get there! to begin than never to end! The following update is in effect I wrote this review, I received an email from their customer support saying they wanted to send me a replacement. I applaud their efforts in addressing the concerns of unhappy customers, obviously they hired a new marketing person. Having a company who stands behind its products is important to me. I'll come back on April 2021 (18 month warranty period) and let you know if the replacement unit continues to function after the warranty period has expired. I am going to rant like this This product was working fine when I first bought it, but I am now worried it may be designed to fail after it has passed its warranty. While the item was not being used, I had it stored in a bin with some other electronics (stored indoors, in a dry, cool location in my office) for a few months. My computer won't start or power up when I took it out to use it again. There is only an 18-month warranty on the unit and I purchased it more than Despite being advertised as having a 24 month warranty on the Bestek website, this item has a 48 month Yet it has only been available for 18 months on Amazon? I contacted the company for a return, but they said "I'm deeply sorry" in an insulting manner. In spite of me submitting pictures of the unit, the message "" appeared. As a result I am posting this review today to warn anyone considering purchasing this product. It might seem good in the beginning, but it will fail you when the most important things matter and it will certainly not be usable 18 months from now.

It will not be able to run a heater, but it can power a deep cycle battery, and is perfect for camp, emergencies, and portable work! I love it! The battery I use for power is great for powering portable devices, especially when I have a battery dedicated for deep cycling (oh, and the battery weighs a TON! Therefore, I guess it is not a hiking type of portable ) d) if not near power sources and away from home
5/5

You know, like that. If you don't want a campground with electricity, camp somewhere else. By establishing a deep cycle setting, it is possible to accomplish the following things 1) Any devices I may have in my house can be powered by this. You might also be able to use it in case of power outage. There can be no massive appliances (space heater or anything like that) but 300 watts is enough to run just about all the things that a person would need away from the city, away from home, when there are Also, the battery lasted for days using this and I was able to run a deep cycle battery for days on it I noticed a 500w version as well.

This is an excellent The adapter I currently use is not the same as the one I used years ago
5/5

There are many who work inconsistently or do not work as long as they said they would. I've had several adapters in my time but the Bestek is the best. The fact that it plugs into the car and has its own cable keeps the adapter out of the cigarette lighter area is convenient for me. With this cable, our inverter can be positioned in an inconspicuous area of the back seat where my kids will use it to power their laptop computers. Also, I have to mention that this unit was used consistently on a 15-hour trip between Maine and There was never a moment when it lost Powered by two wall plugs and two USB outlets, the unit is quite powerful. Investing in this has been well worth it.

It's a great little product to use on my RV and car
5/5

I got the product today, and so far it is working I like it that it seems solid, is a bit smaller than expected (not that I really thought about the size that much) and has a nice appearance. I wanted every time I'm not running my generator to be able to run fans in my RV. As of now, it is working well. The power bank should also be used to provide power to laptops with dead batteries, as I did tonight I have had no issues using it. I plan to use it for small items of the same kind. It is nice to have the power button at the back of the phone The lighter can be left attached to the lighter if you do not want to remove it. The power and longevity of this device cannot be verified at this point (and I will not use it to its maximum power), however it certainly looks and feels like it will last.

I brought this charger with me on a 9-day road trip, it worked beautifully! I brought this charger with me on a 9-day road trip, it worked beautifully! All the AC power I needed was supplied by the BESTEK in spite of my having a laptop, tablet, and extender with two Nikon DSLR camera batteries in at once
5/5

I am very impressed with its durability and the fact that it can simultaneously power several devices. Fan's noise when idle is a bit annoying but it is far from the noise of a standard car. Long power cable allows you to place it a good distance away from the lighter port. This product is great and I highly recommend it!.

So far, the product has been great
5/5

Since I was gifted this over a year ago, it has been working great for me. There are only a few cons in it, such as how many cables are bulky and how you can only plug one in at a time. Although this hasn't been an issue because the additional USB ports have made this less of an issue. Secondly, I've noticed the outlets are really It is a struggle to take out plugs, so I usually have to pull hard. It is not a problem for me that the cords are held firmly in place, as this is what I like. Keeping cords from coming unplugged is helpful when we are moving the inverter around, etc.
My previous inverter broke after a year or two (it was not this brand) so far the BESTEK appears to have a better build quality.
