BESTEK 1000W Pure Sine Wave Power Inverter DC 12V to 110V AC Car Inverter with Digital LCD Display 4.2A Dual USB Charging PortsClimatePartner certified

I have so many thoughts on this inverter, where do i start?I paid $138.99 in December 2019.first off it does work and yes it puts out the clean pure sine wave power.I first bought the Bestek 300 watt pure sine wave inverter and liked it so much that i bought this unit when it came out & only had a few reviews because i had faith in the brand.I saw power out put as rated by my Kilo-watt meter read as low as 102 volts with a heat gun loaded up 950 watts and as high as 117.5 volts with just about no load, the meter showed 59.9 hertz most all the time with occasionally reading 59.8 and only a few times did it read 60 hertz evenPro's and con's! here we goPro'sit has powered everything i wanted it to and more, (one item at a time) my kitchen LG refrigerator (4yrs old) & garage fridge (13 yr old old style compressor type high load starting) a 6yr old HE front load washing machine & my house furnace, yes the home furnace! i rewired the furnace by removing the Romex and wiring a 12 gauge heavy duty grounded plug as its input then wiring the Romex into a standard plug the the heater can plug into.My furnace is a high efficiency 90%+ variable speed natural gas furnace that uses about 400 watts on the low and 900 watts max on the high heat setting. i powered up the furnace and let it run two heat cycles of 15+ minutes each in the low setting over a 45 minute timeline and the little Bestek worked great.the inverters fan would vary its speed with the load, but i never even felt hot air came out.USB ports have power with the unit powered off but of course hooked up to a battery.Battery power input listed on the front does seem real accurate.The output wattage also seems to read correctly accordingly to my Kilo-meter.this even powered up the old garage refrigerator that takes at least 1070 watt load to start it, once it did i ran that fridge for over a hour, on another day i ran my kitchen fridge for 4 1/2 hours with no problems from a fully charged Interstate marine deep cycle battery.Con's#1 at a draw of 950 watts the voltage read by the kilowatt mater showed 102 volts!The fan runs as soon as you power up the inverter even with no load applied (unneeded power use).The little green power button light seems like it is only 1/3 lit, so its a little hard to see.The power output that it list is it's putting out 115 volts but that does not reflect the real voltage output.The supplied power cables are really short but they worked fine with out getting even warm for me.The 4 fuse's it uses are a ATO (automotive style) fuse rated at 50 amps each, and i have never seen that high of amperage in that style of fuse and i worry i would have trouble getting replacements locally (luckily it does come with 4 extra's).There are no mounting legs or tabs of metal sticking out to allow you to mount this inverter to a solid surface.In all reality I'd really give this 4.5 stars if possible, but i think i can trust this unit as a I have run it a good amount testing it out over the last month, i ran it hard & in case it failed i was going to return it but it was good enough for for my needs, knowing i would not run it at even 60% of its capacity.Edit 1/2022 i realize i should have mentioned to always over size your inverter by a good margin say 50% larger than you need. I Have upgraded my battery back up system early 2021 i built a different semi portable system using Battle-born 100 amp hour battery & installed a Giandle 2,200 watt pure sine wave inverter. the large Giandle's fan doesn't even need to come on until about 800 watts pulledwow! is all i have to save, lead is truly dead for me!i still have this Bestek and its still working fine,sorry for the rambling review as i dont give many but for a product that i do like and was worried about its worth my time and hope it helps you.

I had been wanting a bigger pure sine inverter to run my electronics. I also have a couple Bestek 300w pure sine inverters and they've been good, so it was a no brainer. Build quality is nice as expected, and the display showing battery level and wattage is nice to have. No surprises here, it works great, I've tested it up to ~500w and it didn't skip a beat.My only minor complaints are that I wish the battery voltage part of the display was a little bigger and I wish it had a low voltage alarm like a lot of other inverters do. In testing I kinda forgot about it for a while and just when I noticed the voltage was dipping around 10v with a little higher load than average, it shut down. No harm done and I usually pay more attention when running off battery but it would have been nice to get a warning.

This thing spits out a ton of clean current and does so for hours without breaking a sweat.After unboxing, I hooked it up to my 100ah lifepo4 12v battery and immediately tried plugging in my gaming PC. Running Shadow of the Tomb Raider, it pulled around 580 watts and ran just fine, like it was plugged into the wall. I then tried plugging in a small room heater. It ran on high, med, and low no problem, but it was pulling over 1300 watts on high, so I kept it on low which pulled around 800 watts.After 10 mins on the low heater setting, the 8awg cables that came bundled with the unit started getting uncomfortably warm. I was a little unnerved, so I took them off and put on some 4awg cables and those ran much cooler at the power levels that this unit would be pushing.4awg cables are what should have been bundled with this inverter! But the unit itself is an unexpectedly solid workhorse so I'm not too disappointed.

I've had this in the trunk of my car for a few years now, to turn the car into a generator when needed. Using your car as a generator is very practical because it always has gas in it and can idle quietly for a long time. personally, i fill up my tank when it gets to halfway. Traditional generators can be annoying to maintain because you dont want to let the gas in it go bad. I have a honda crv 2.4l engine. Do this at your own risk and check if your car can handle the load, but these are my steps for turning my car into a generator:I pop the hood, lay down a piece of wood and set the inverter on it so that its not next to the hot engine.then attach the cables to the batterystart the car, then turn on the inverter and plug in the load.then lock the car using the spare keyIve had a consistant 700 watt load running off my car. I could go higher but i dont want to put stress on the alternator and battery. also, as others also mentioned, yes the included cables are too weak for 1000w sustained load. Im going to find thicker replacement cables. this inverter was a life saver last year when it powered my sump pump during a power outage. Despite being stored in a freezing car as well as a hot car sitting in the sun, it still works when I test it once a year.
