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:	Does the 400w have undervoltage protection
Answer:	Yes, because the maximum wattage it can hold is 150W and your heating pad is only 50W.
Question:	What is the undervoltage limit? will it operate down to 9.6v on a lithium-ion battery
Answer:	Not exactly sure but the company that manufactures this excellent item seems extremely responsive and responsible! I emailed them with a question and they responded immediately! I have purchased 2 of these and got great use out of them all summer going offroad to the beach. A terrific product
Question:	How long is a cigarette cord lighter plug
Answer:	Occasionally this can happen if dust or some other material gets onto the valve seat, however it is usually simple to rectify:- Unscrew the tire gauge stem, pull out the brass plug and check the o-ring is aligned correctly.- Tap out the black/white (black on top) valve seat and spring below the brass plug, give a gentle blow down the stem while pressing the bleed button on the side and re-assemble.- If this does not work, it could be in the bleed button stem. As this is not accessible, a drop of lubricating oil down the bleed button stem can often solve the problem.We will of course replace the tire gauge if it proves to be defective in any way, however this is very rare and if you wouldn't mind just trying this first and let me know, it will correct the problem 99% of the time.
Question:	I want to plug a heating pad (50 watts 120 vac) into my car lighter. is this device appropriate for that
Answer:	All metal, you can even unscrew the end and you will see the inner tube construction.

User questions & answers

Question:	Will this Run a computer
Answer:	I would assume so as long as it doesn’t draw too many volts. Does your computer draw 110 V? If so you should be fine. Worst case scenario is that you can hook it up to your battery posts and it increases the voltage a ton. I was able to blow up an air bed with it that way.
Question:	Does it works for sump pump
Answer:	Why would one need a pure sine wave converter for a sump pump? If you are trying to run precision analog electronic measurement equipment or are worried about EMF noise then you might need a cleaner power supply. It's true that startup draw might be large for a sump pump, (peak power needs might be 2-3 times base draw) but pumps don't need clean harmonically pure power waveforms. They will run on square waves just fine.
Question:	Does anyone use this in a truck
Answer:	Cars operate a 12 volt electrical system and trucks operate at 24 volts.The inverter has to be suitable for the supply.
Question:	Sump pump
Answer:	This is not a pure sine wave inverter, It cant work for it

User questions & answers

Question:	Will this work using the cigarette adapter for a device with the following specs? 120vac , 60hz, 500w
Answer:	How long to Kill (completely discharge) your battery will depend on the size and condition of your battery AND the power load you require from the inverter. For a relatively new, good condition battery. With a load of 50% or max (375 watts) the inverter will draw about 450 watts from your battery. For a typical compact-car battery rated at 35 Ampere/hour (441 watt/hrs) capacity, the battery will be "dead" in less then one hour. For a high-capacity battery in a large SUV or pick-up truck (100 Ampere/hrs. or 1260 watt/hr) capacity, the battery will be "dead" in about 2 1/4 hrs. or less. At higher inverter loads the run-time will be proportionally less. Discharging a typical vehicle battery to less than 40% charge is not a good idea and will result in a shortened battery life, and possibly not being able to re-start the vehicle"s engine. For best results, the engine, and therefor the vehicle's alternator, should always be running when this inverter is being used to power any load of more than a few watts.
Question:	Will this work with a brother laser printer 110-120v- 50/60Hz 9.2A
Answer:	There are 2 heating elements in a coffee maker and between the 2 of them they take more initial amperage then the inverter can put out.
Question:	Does it hold charge
Answer:	The unit will not operate on anything less than 10.5 volts
Question:	Can you use it with the engine off? If Yes how long will it take before it will kill my cars battery
Answer:	There are supplied power and ground cables that have eyelet connectors that will hook up directly to the battery terminal.

User questions & answers

Question:	Will this drain the car battery and does the car need to be running to use this
Answer:	Other people are saying yes you can run it with the car off but there’s more too it, the lower you discharge the battery the more it needs to be recharged. That process is what shortens the life of your car battery. If you want to keep your car battery as long as possible I recomend only iseing the inverter while the engine is running
Question:	The descriptions and photos here show TWO(2) AC Outlets, but some reviews say it only has ONE(1). Which is it
Answer:	The unit that I received has 2 110v outlets and 2 usb ports. The unit was used on a recent trip to Texas and worked flawlessly.
Question:	What are the dimensions of this device? Length width and height
Answer:	In centimeter they are as follow;Length 12 cm = 4.72 inchesWidth 7.80 cm = 3.07 inchesHeight 4.5 cm = 1.77 inchesHope this is helpful
Question:	When I plug my laptop into it, and then play music through my laptop I get really bad cyclical sound ... is there a way to filter this out
Answer:	Your headphones are (probably) picking up the electomagnetism put off by the inverter. Move away from the inverter and see if it goes away. If not, then insulate your headphone wire. If that doesn't work, then try it with someone else's (preferably new) laptop. Some cheap/old laptops are built with too few capacitors and you probably shouldn't use this inverter. (Alternatively, you could hardwire capacitance into your charging cord). It's also possible that the product is not actually putting out a proper waveform. It works fine on my laptop, so I haven't tested that yet.

User questions & answers

Question:	If i wanna use this in the cab i just plugin into the cigarette adapter, right? or, do i need to use the battery clamps for the inverter to work
Answer:	It will draw about 340 mA from the battery, approx. 4W, or 1% of its max power.
Question:	If i wanna use this in the cab i just plugin it into the cigarette adapter, right? or, do i need to use the battery clamps for the inverter to work
Answer:	It does not work for a late 2013 13" MacBook Pro. The unit functions normally with the MacBook power supply plugged in. But as soon as you connect the MagSafe connector to your laptop, every 2 seconds it goes into protective mode, cutting the voltage. That has been my experience, YMMV.
Question:	does it really supply 400W. I don't want anything blowing up
Answer:	Coolest question EVER!! Sounds like a blast and who else will look that good when camping/sleeping in their cars!?! YOU!! I think a curling iron/straightener would be too many watts (watt usage should be on the grip area/raise printing?)...It can only handle 400 watts with a 800 watt (brief) startup surge (as I understand it....many other experts could tell you better)...but the heating type units (blow dryer, curler, etc) use over that....you could get a more powerful inverter (2000 watt) and hook it up to the battery of the car (alligator type clips, red to red, black to black) and that could do it....again look at the watt usage....oh, and HAVE A BLAST!!
