BESTEK Pure Sine Wave 1000W Car Power Inverter DC 12V to AC 230V 240V Voltage Converter with Dual USB charger and Smart LCD ScreenClimatePartner certified

Did a lot of research on these. Decided on this one as it can provide power to a fair range of appliances, which we use on the motorhome. As an example 1200W hair dryer (on half heat) 700W remoska oven for an hour, 170W slow cooker, electric bike charger, lap top etc etc. This is used in conjunction with a 150W solar panel and a 90Ahr Varta Leisure battery. You can keep an eye on the display and it will show the power that you are using and the battery current available. Be careful not to take to much out of the battery, using heating elements!The unit also has two USB sockets which are great for device charging ( phones, Garmin gps etc)The two 240v plug sockets are to close together. It only really needs one but no big deal. The display could be bigger then!When running the cooling fan makes a little noise but thats fine and it keeps the unit well cooled.The cables it comes with are to short. I had to make my own (I used bigger diameter welding flex cable, for better current and heat considerations) as I have clipped them onto the Leisure battery terminals and can now position the inverter on the seat inside the vehicle.I also wanted a pure sin wave inverter as it will (I hope) work with all electrical equipment well.So far so good. I have "road" tested it and for the range of equipment we need power for, it does what it says on the tin. It is a nice, compact, good looking practical piece of kit to have on any van.If they got rid of one 240v sockets, provided slightly larger, longer power cables and made the display a little bigger they would have a 10 out of 10!!I would recommend you give this unit high consideration.

I use this inverter on my boat and love it. Great product!

Purchased one, received used unit with no cables, spare fuse or instructions. Returned and re-ordered another, exactly the same thing again. Presumably they get so many returns the seller just continually churns them back out in the hope some mug will keep them. Subsequently ordered a GIANDEL 1000w inverter which probably weighs twice as much and is built to a very high spec. Boiled my travel kettle in no time. Much cheaper too!!!

Background: I have dabbled in small off grid solar (400w) setups for some time, including a remote location garage, and have been looking for a well built pure sine inverter of up to 1000w to allow use of more sensitive equipment such as TV, chargers,laptops etc. I won't go into the pure sine wave benefits here as there is plenty online.First impressions are of a solid sturdy unit with four 50a fuses to cover overcurrent, temperature and short circuits, with a good quality and informative LCD screen showing a very steady 230v output(I have never seen this waiver), a DC input voltage which will fall quite rapidly if you don't keep the battery topped up.Please note this is way too powerful for a cigarette socket in a car. Car cig sockets use vehicle wiring (about 1.5mm) and are fused at 120w. This comes with 10mm cables (6x the size of car wiring) that need to be connected direct to a battery, as it can take 1000w, which would burn through your car wiring in an instant.When you make the initial connection to the battery take care, as with all inverters, it will spark when you touch the lead to the battery. This is normal , but can be alarming ( make sure there are no flammable liquids nearby) and there is no warning in the instructions.I have upped my cables to 20mm (13x the size of car wiring) to be safe as the supplied cables get quite hot at 800w+ .(If you want to run a pure sine Inverter through your cigarette socket, Bestek do another pure sine 300w max at £41.99 on Amazon, comes with cig plug, but you must only use it up to 120w on a cig socket, after that you need an adaptor to use it up to 300w direct from battery).Some adaptor transformer plugs ie phone or tablet chargers draw less than 0.25 amps and may not even register as a draw on the inverter, especially if the phone is nearly full as it would be a trickle charge. Before thinking the inverter isn't working, try something more powerful like a TV or kettle!Please note it is more efficient to charge a phone direct from usb (12v to 5v) as it is far more efficient than taking 12v, changing to 230v, and then back to 5v, by using a standard mains wall charger plugged into the inverter( lots of wasted power!).I have a 650w travel kettle which does draw in excess of this(700w), but still well under the 1000w limit of this inverter and the inverter copes fine, the variable speed fan increasing in speed as the unit works harder.I have also powered a 750w sandwich toaster (draws upto 850w) and a 40" LCD TV (160w) and a slow cooker (89-157w) in various combinations.Care is required with all inverters, as rated wattages on appliances can be more than product labels ( as above), and more so if they involve a motor/central heating pump/drill/fridge or microwave, as these can use a much larger current when starting up the motor than when running.I also inadvertently connected my sandwich toaster and TV at the same time and exceeded 1000w very briefly according to the LCD screen(see pic) on the inverter, however I unplugged the TV and no fuses tripped, so it seems there is a little spare capacity at least for a short period.The inverter automatically shuts down if the input DC voltage exceeds its limit, this happened due to the relatively cheap solar controller I had originally, which spiked in voltage briefly when the sun came out from behind a cloud!(I have now put in an MPPT controller which has resolved this issue).To summarise, this is a very solid inverter, with good protection of over and under voltage, quiet fan, well capable of output of 1000w and powering sensitive equipment such as TVs and chargers, as well as kettles and cookers.I have used it for ten plus hours daily for slow cooker, TV, occasional kettle etc with no issues.Update 17th September 2020, I have used it most days for ten hours or so since purchase with no issues.Some simple things I would like to have seen included:Confirmation of the peak load capacity in the instructions as this is not mentioned anywhere.A standby feature that powers down when no load/fan off when no load as the fan does take power continuously.I also feel the cables could be thicker as they get warm at 800w upwards, and I have now changed them to a hefty 20mm from the supplied 10mm which hopefully is overkill (last picture), however if you don't intend to use its capacity over 800w for very long, the 10mm cables will probably be ok.Update 19Mar21, still going strong with use most days depending on solar. Please note two UK approved plugs do fit, just don't buy plugs with the lugs on the side aimed at helping less dextrous hands to remove a plug from a socket.Update May 2021, this is still going strong in regular use, please note I can see a couple of reviews saying people have received a duff one, which I guess is inevitable as no production line is 100% perfect, however Amazon offer returns on faulty items if found immediately and up to thirty days or so, and their Customer Service Team will get involved if the seller is non responsive on warranty queries so I am very surprised by several of the reviews. Please note that any motor, for example a central heating pump or vacuum cleaner, whilst labeled at under 1000w, may need four to five times this on startup. As with all motors, it has to overcome the initial inertia of the liquid being pumped, friction or just its own internal resistance. Once running it may well be 300w, but a 1000w Inverter could get fried pretty quickly from the start up current, or at very least kick in its safety devices/fuses, leading you to think it is erratic. This product is high frequency design (GoogleMOSFETs and chips for the technical amongst you) and its surge capacity for higher wattage beyond its maximum is likely very limited. Either a much bigger capacity inverter or a 'low frequency' inverter (that uses big copper coils heavy/expensive) would be a better idea for induction loads such as motors.July 2021 as the inverter is so capable of handling the various demands I have placed on it ie travel kettle, sandwich toaster TV etc, I have upgraded to two new batteries and a fifth solar panel in a new location, early days but inverter should be used even more as we have more power storage and also useful as a backup for basic power in a rural area subject to outages. Have also recently been using it with a 500w hedge trimmer, seems to cope with the start up surge ok and fine.12 September 2021 - Inverter is now powering a tall freezer during the day, which surges briefly at 1200w, without issue, then falls rapidly down to 100w or so, for about ten minutes every few hours. It then ticks over at 2.5-5w the rest of the time. Be warned! The fridge label says 50w an hour, but this is an average... Be prepared for huge surge at startup as above. I have tried it with our older fridge, but this surges at 1300w and shuts down, which is to be expected as it is well over the rated output of 1000w.I note some people have suggested it is not a pure sine wave as it causes interference on their radio however they are confusing radio shielding with sine wave output and are two different things. High frequency electronics, can and do emit electronic noise. Using the the inverter to power their radio from a distance will likely be fine, providing grid quality power and unlikely to damage sensitive electronics. However many electrical items from food mixers to electric fans can have inadequate radio shielding of their motors(cooling fan) or other high frequency components. Unfortunately this can interfere with radios. If you are unable to site the inverter away from such equipment it is probably not for you. Pure sine(which this is) has little interference capability in its own right, as it's wave form is a gentle curve, not stepped as with cheaper inverters. Hence being able to power sensitive equipment (TVs, drills or other things with motors) without damage or overheating.

I have been using this inverter (my first) in my off-grid shed for over 18 months now. it runs a fridge, CCTV, WIfi etc. My only criticism is, if I want to convert my shed into a tiny home, I am going to have to replace this inverter, it is never silent, the fan continuously runs even without load even in the Winter.My second inverter is a 3000W from a different brand and it is completely silent.

Purchased this inverter to power an outdoor pond water pump. Build quality seem very decent. However, not sure if this is the nature of inverter or faulty unit. While running the water pump, according the plug in power meter, the pump consumes about 25W of power, which is within the spec of the pump. However, the inverter's LCD says 63W. I was expected some loss from the inverter, but not 63W-25W=38W loss on 25W load! I'm not sure if this is expected or I simply have a faulty unit. Checked the pump and plug in power meter on normal main which of course is fine, hence I turn my doubt on the inverter.

Likes:Build quality.2 x 3 pin mains outlets.2 x USB outlets.LCD showing battery voltage & Mains output voltage and wattage of attached equipment.On / Off Button on the front for easy access.Dislikes:I would have liked a separate lead which could be plugged into the car accessory socket in the boot for running lower power items up to 120w so I didn't have to extend the crock clips to connect it to the battery under the bonnet. It looks like I will have to make up my own lead for this.Price is a bit high.I would recommend this item to anyone looking for a well made unit that does the job it was made for.
