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

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.

Likes:• Compact with handle• Lightweight• The display is mostly accurate 2 tenths off on voltage...maybe line loss• The price was low enough that I bought the insurance!Dislikes:• Fan noise….this is the price we pay for small compact case• I wish it were bigger:) I think.1500 watts would be perfect so thatI wouldn't worry about not starting a small motor /fridge• I would like to see the terminals on the inverter be more robustSet your Expectations:• Able to handle my full size newer GE fridge ….note you may need to let a fridge sit awhile after initial power disconnect to unload pressure…I ran my full size fridge and a 50amp lfp for over 3 hours with no problem after I let it sit 20 min or so• I think this is perfect for non continuous use...ie power outages, camping trips etc. If connect it to your beer fridge in the garage with a solar panel outside expecting it to last months or years you will probably be disappointed

I had a 1000W modified sine wave inverter I bought locally that was unable to power my Keurig coffee machine nor my cheapo "900W" microwave. This pure sine wave inverter is able to power both, and didn't cost much more. I was hesitant to purchase this inverter because it didn't have any reviews but let me tell you... it's worth every penny!The built in display on this inverter is a great feature. It tells you battery voltage and current load. My coffee machine used about 1100W and my microwave used almost 1200! Despite being over the rated output of this inverter there were no issues. I suspect this inverter has a higher peak output rating, although the manufacturer does not publish it, so it should work fine for appliances that need a lot of power to start (refrigerators, pumps, etc).It's worth mentioning that the built-in fan can get pretty load at full load... then again, that's perfectly reasonable given that I was pushing the inverter very hard. At low loads and idle the fan is much quieter and sometimes even turns off.Build quality is exceptional. The case feels solid and didn't get warm at all. And while it's hard for me to test without an oscilloscope I do believe it truly is a pure sine wave inverter since my microwave worked perfectly (when I tried it on the modified sine wave inverter it made a terrible noise and didn't create heat).The only problem with this inverter is that the included cables to go to your 12V battery are simply inadequate. While I understand that thick quality cabling is expensive, I would have happily paid $5 more to get thicker cables. The included cables got hot to the touch even though I was only using the inverter for about 2 minutes this time. I don't even want to know what would have happened if I'd run the microwave for a longer time! And besides getting too hot, the fact that the cables aren't thick enough caused quite a bit of voltage drop... According to the display the input voltage went to 10.X V instead of the 12.6 V my battery was at. While obviously the voltage will go down if you're demanding a lot of power from the battery, it shouldn't go that far. With better cables I expect to see at least 12.0 V under load.Overall, I recommend this inverter, although it's not a solid 5 stars... more like a 4.5, due to the included cables being a fire risk. Just keep in mind that in addition to buying the inverter you'll need to pick up some good cable, 2 gauge at minimum, 1/0 or 2/0 would be better.
