User questions & answers

Question:	Does this supply 500 watts through the cigarette lighter
Answer:	Only technically yes, if your cigarette lighter can deliver 49 amps. The cigarette lighter in our car is powered through the ignition switch and has a 10 amp fuse on it. Those 10 amps at 12.6VDC translates to about 100 Watts at 115 VAC out of the inverter.
Question:	How long will it power a modem/router
Answer:	It depends on your power Source ... the Battery. But for a modem ... for a Very Very long time indeed : ) I use it to power a mixing board for sound applications and it's Great for several hours using a small emergency battery intended for lights. The word EXIT might come to mind here : )
Question:	Will this power and run a 32 in tv with a cd player. Tv is led
Answer:	Some electronic device require pure sine wave AC. Or else ... smoke
Question:	What is the no load power draw
Answer:	“No load” power consumption is the power consumed by a device when it is plugged into a power outlet. In this case, I think if you are not “plugged” into one of the Converter outlets the “no load” consumption my be affecting your battery (power source) only. Additionally, the Coverter must be turned on.

User questions & answers

Question:	how loud is the fan? how long is the cord from the cigarette lighter to the product

Question:	Will this power inverter handle a curling iron or hair blow dryer
Answer:	I think this first aid kit for common wounds and injuries and It would not be applicable to treating gun shot wounds.
Question:	Used it in the car with two tablets and it will charge, but tablets cannot be used at the same time. Is this normal
Answer:	YES
Question:	is the output (110VAC) regulated at 60 cycles
Answer:	Of course, you can use the emergency blanket to keep you warm, as it reflects body heat back to the body. And there are various uses for the emergency blanket also: 1) You can use duct tape and an emergency blanket to make a toasty sleeping bag for a child. Simply fold the bag over and tape the edges together to create a sleeping bag. You can also use them as lining for an existing sleeping bag to retain more heat.  2) Since emergency blankets are good at keeping heat in, you can use them on your windows if the power goes out. They will reflect back light from a fireplace indoors and create a pocket barrier in your window frame to keep the cold out.  3) If you're out hiking and get stranded, an emergency blanket would make a pretty helpful shelter. It might not be able to withstand a lot of extreme weather but it will keep rain off of you and keep the warmth in. You can use the blanket to make a simple lean-to shelter in the woods. 4) Emergency blankets are very reflective. They would make a great signaling device to search and rescue helicopters or cars from a distance. 5) Fire Starter. Emergency blankets reflect nicely. Line a bowl (or hole shaped like a bowl) with a blanket. Place some kindling in the middle of the blanket and angle the blanket to it concentrates its light into the center. The concentration from the bowl shape will transfer the sun's light to ignite the kindling.

User questions & answers

Question:	Modified sine wave or pure
Answer:	Dear Customer, this inverter produces modified sine wave.If you have any other questions, please contact us through the Amazon messaging service or by e-mailing [email protected], we are here to help~
Question:	Does this have a fan? Is it always on? Is it loud
Answer:	Yes it has a fan, no it is not always on and it is very very quite. There is a switch or should I say a button that you push to activate the 110 outlets and a green indicator light comes on to let you know that both the 110 outlets have been engaged and the fan to keep them cool. The USB outlets and the cigar lighter socket are always available with or without activating the fan/110 inverter. I use this device every day operating my dash-cam and charging my phone and Kindle HDX. I have also used it for my laptop from time to time. Works quite well but do keep in mind that you are drawing from your car battery and if the engine is off you need to start the car once in a while to keep it charged. I have also used it to power a guitar amp but found an RF frequency buzz zing thorough so I didn't do it for long. I believe if I plugged in a power cord and put the amp out side the car that may have helped however it was raining so I didn't. 
Question:	Does it make loud noise when it working
Answer:	To add to all the other answers, it does make a whirring noise when on but you only need to turn it on if you’re using the large plugs. You can leave it off and the USB ports will still charge.
Question:	if the fan is in the bottom and its in a cup holder, how does it efficiently dissapate heat? i know there are small standoffs at the bottom
Answer:	The vent on the top allows cooler air to enter the power inverter cup. The base of the power inverter cup is slightly elevated thanks to the little feet at the bottom so that the warm/hot air can escape.

User questions & answers

Question:	Rattling sound coming from the unit after i shake it a bit or move it is this normal? Sounds like a Maraca
Answer:	Doesn't sound normal. Must be something floating around inside. Return it or.... if outside the return window take a shot and open it up. Might be a loose nut or something that can loose.
Question:	If i have something thats 200 watts will this be able to handle it? Is it 300 watts max or 150 per outlet
Answer:	I've pulled 300w out of a single outlet and wasn't using the other plug. So the total output between both should not exceed 300 watts.
Question:	Can i use this for something 140 to 200 watts? i have a bestek 300w but what im trying to power cuts off and on repeatedly. needs to be pure sine
Answer:	I have pulled over 300 watts through this inverter many times with no power interruption. There may be an issue with your inverter or perhaps the vehicle circuit you are using to supply power to it.
Question:	What are the dimensions of the inverter? In inches please. The package dimensions are listed but i want to know the actual inverter inch measure
Answer:	7.5L×4 3/8W×2.5H in inches. This includes the spin-on terminal nuts.

Replaceable fuse

The product includes two spare 2 x 40 amp/32V fuses, externally replaceable fuses, which provide protection when connected to the battery, and can be easily removed/replaced from the back of the inverter; when hung at the point When the cigarette lighter is on, it will use a 15 amp fuse for the car. It not only has a built-in insurance function, but also has a reverse polarity protection function. When the positive and negative poles of the battery clamp cable are reversed, the diode inside the article is equivalent to direct conduction, which will generate a large current. At this time, the fuse is blown to prevent damage to the items. In this case, users can still replace fuses of the same specifications.

Connect with Alligator Battery Clamps

The power supply and battery are used as backup power for the inverter. To use power from 150 watts to 300 watts, it must be connected to the car battery. The current consumption is 0.005 A in the closed state and 0.3 A in the open state. Therefore, do not insert it into the car when not in use. The battery clip is very strong, similar to a jumper cable clip. Not a backup battery, this is a power inverter and requires a battery to operate.

Cigarette lighter plug connection

It can convert AC power for use in the watt range. Whether you want to use its power source, you can use the cigarette lighter plug to power the battery to pull the crocodile-shaped battery clip out or directly onto the car battery. The 12v cigarette lighter socket provides continuous DC to AC power without draining the battery due to insufficient voltage. The 12V plug is spring-loaded and can be firmly inserted into the socket. The 12-volt cigarette lighter plug cannot provide 300 watts of power and requires an alligator clip for car batteries. If you want to plug it into a car cigarette lighter, you should keep the power below 150, because this is the purpose of most car fuses.

User questions & answers

Question:	How many amps does it draw when it's on with no load
Answer:	About 5x3x2 inches. (I just went out and measured.)
Question:	Is this appropriate for use with a laptop
Answer:	This device provides electric power while your car motor is running. So that the alternator continually recharges the batter. If you take the battery out of the car, the inverter will provide power for a short time. I only think of this inverter providing power while the car motor runs.
Question:	Can I use a curling iron or hair straighter with this? I was thinking of buying one of these to bring to Coachella for car camping
Answer:	They are very well built inverters. I have 3 400w inverters, for different solar projects, and 1 2000w, which I use to power my fridge, if the power goes out. The 2000w inverter is connect d to a 125ah vmax battery. If you leave it in your car plugged in, just make sure you have it powered off. The inverters are great. Hope that helps.
Question:	what is the measurements
Answer:	Yes, I am. I received an old item which should be a new one.
