BESTEK Pure Sine Wave Power Inverter - 1000W Car Inverter DC 12V to 110V AC - Car Charger Adapter Outlet with 4.8A Dual USB Charging Ports - Digital LCD Display - Aluminum Housing - Rubber HandleClimatePartner 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 have only short term tested the unit but so far I am impressed. I have not long term or really stress tested this but that is not how I plan on using it. This is the planned use... Occasional short term tailgating or emergency use that leaves plenty of margin on the rated capacity. If there is a greater need then I will use my small inverter generator.This is a replacement for a different brand Of true sine wave inverter I had where the company is no longer in business. That one last lasted many years and I hope this one will as well.What is important to me:1) True sine wave2) Form factor3) Reputable brand/quality3) Rated Watts4) Price point5) Easily replaceable fuse6) Informational displayThe form factor is so handy that it actually increases its practical usability. It is smaller than I expected and without the sharp edges, The handle makes this is so easy to break out and use. It can easily be stored in most vehicles. It is smaller than I expected which was a pleasant surprise.My wish list for the next version of this product:1) Relocate the ground screw so I can run the input power cables up towards the handle rather than have the negative cable stick out the side.2) Make the cables a little more heavy duty and a little longer.3) Any bump up in rated wattage and surge wattage rating would only make this little device even more awesome. I do not like running inverters near their limit so having extra overhead will expand its usefulness and safety margin.4) The replacement fuses seem to be the type you see in many cars but are a high 50 amperage size that is not common. It would be handy if more common fuses were used or if there was resettable breakers instead. Thoughtfully the inverter comes with a set of spare fuses so if needed you have time to source replacements. Overall this is a great device to have in case of emergency, tailgating, or anytime a quick source of AC power is needed.
