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 Handle

I purchased a slightly cheaper 1000W modified sine wave inverter, while this was fine for running my refrigerator, I was unable to power my Cyberpower UPS. The device was not able to correct for the square wave output of the cheaper inverter and did not deliver a clean output to my networking equipment. Further research lead me to sine wave inverters such as the BESTEK. This unit was partically attractive because it was cheaper than other inverters and had a battery clip (For quick connection to a car battery). I plan on using this to power my refrigerator, UPS, and possibly some lights when experiencing a power loss for more than an hour. I was able to power everything without any problems. The unit itself outputs around 115-116V with around 12.5V input, and slightly higher 117-119V at around 14V input when my car is running. The voltage measured at a consistent 60.5Hz, which is slightly high but shouldn't matter much if isolated from the grid. It doesn't seem to make much noise but I'm also using it in the engine bay of my car so it doesn't matter much. I feel as though the intentions of this small inverter is to leave it in a car and quickly connect it to the battery when needed. I would STRONGLY recommend also having a second car and jumper cables or a small USB jump starter in case the battery runs low. Every battery has different capacities so for short outages, you won't need to keep the car running, but for longer outages I would start the car for a period of time every few hours. My car struggled a bit to start with the inverter connected under load, so disconnect it first before starting the car. If anyone is interested, I am using this inverter to power a CyberPower CP1500PFCLCD. My networking gear includes a PC tower running pfSense as a router, a file server running Unraid which also runs a Unifi controller, a Netgear switch, Netgear CM600 cable modem, and a POE injector for my Unifi AP. The UPS lasts about an hour under a 150W load, which is enough time for me to hook up the inverter. Everything seems to run off the inverter fine. Since most modern devices won't run off of a modified sine wave inverter (Or will run, but may actually get damaged from the "dirty" power), this is worth the money. 1000W is enough to at least run a refrigerator and networking gear (Usually internet will work when a cable modem is powered, even during an outage). I will be keeping this in my car for road trips too, it should be enough to power all mobile devices and more.

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.

The first one I received was defective and had to be returned. The return process was very easy and credit was given quickly. The second one worked perfectly. I connected it to my trailer battery and powered an air compressor to inflate the tires. It will make a good clean backup power supply at home in case of power failure. The only thing I would ask for would be to include battery clamps so that you don't have to undo the battery to make a connection.

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 even Pro's and con's! here we go Pro's it 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 pulled wow! 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.

Very light and compact, powerful at the same time. 7A grinder started with no problem, 150W fridge also starts and works without any issue or overheating. Love the unit. One thing to note that it can not be left connected to a battery for months even when it is powered off. It draws around 30mA to power USB ports, which are always on, and that would drain 8Wh a day.

Excelente inversor

So portable and easy to use. I needed a PSW of at least 1000 watts. This is so easy to carry and use. It's light weight and has a nice little handle to carry it around. The display has all the usefull information you'd want on an inverter. Really happy with this unit.

Lo he probado con varias herramientas de buen consumo y ha cumplido con mis expectativas, mi computadora portatil trabaja excelente, solo falta probarlo por varias horas para medir consumo y resitencia, tengo 2 dias con el, hasta ahora lo recomiendo

This is a fairly good inverter. I have extensive experience with all kinds of inverters for different applications. In this project, I was building an interrupted back power supply for my fridge. It has a surge of 1800 watts and runs at 15 watts. I got a 100AH AGM battery and an automatic battery charger to charge the battery when the grid is on. When the grid is down, the inverter would continue running until the battery runs down. I have built a few systems for years. The inverter I would normally use was discontinued so I decided to buy this inverter. The build is great. All the ports give a clean pure sine AC wave (tested). USB and LCD screen are all very good. The LCD screen has useful info on power in vs power out, voltage, and consumption. It’s rated for 1000 watts continuous use, and can handle up to 2000 watts for a surge (less than a minute). The price for what you get is great. HOWEVER- I have to knock off a star just because of the cooling fan. It is loud even with out a load, and when it has a load, it’s louder than the fridge. It’s very noticeable. For my needs as a UPS for my fridge, this really is a big deal. The frustration is everything else on this inverter is top notch, why skimp on the freaking cooling fan?!? Get a silent ball bearing fan and this inverter would be hard to beat at the price point. Right now, I only use the rig I built when there is a blackout (which is 3 times where I live), and manually turn it on rather than use it continuously as I wanted to. It works but that fan really is a pain point.
