Perfect for off-grid system, lower THD, less wear, strong inductive load capacity. Review: Works great - Just right. Bought this to charge a gaming laptop and meta quest vr head set in truck. Works perfectly. It is a bit loud but you ONLY NEED to turn it on if you are using the plug. If you are just using the usb to charge phone or something it does not have to have the fan running. Review: Compact and light for a 500W inverter. High efficiency - Great little unit. Works brilliantly powering the 'sensitive' items I've tried so far, all using the 12v power plug. Fan runs immediately from switch on and is noticeable, as others have commented. Case remained cold at the loads I was running. The supplied croc lead cable is not of sufficient size for much above 300W, and would need upgrading, but that's not an issue for me, and I would recommend this unit and buy again, especially at the price, and fast delivery. ## Features - BESTEK 500W Pure Sine Wave Car Inverter:Its output waveform is same as the AC power waveform of mains power grid which delivers a smoothly-varying sine wave for sensitive electronics provided by the electric utility.Perfects for off-grid system,Lower THD,Less wear,Strong inductive Loads Capability.It has little interference with radios, communication and precision equipment.It's also recommended by most cordless tool manufacturer that a pure sine wave inverter is used to ensure long battery life - This is an inverter converting DC from your car battery to AC for whatever you want to use within its Watt range.It can pull power from the battery through the cigarette lighter plug or directly clamp the alligator battery clips onto the car battery.Plug this into 12v cigarette lighter outlet provides continuous DC to AC power with 2 AC outlets operates any 110v device and 2 USB ports which detects your device automatically to deliver its fastest charge speed up to 2.4 amps per port/4.2 amps max - Isolated Voltage Protects Perfectly for your device from Over-voltage,Under-voltage,Overheat,Overload,Reverse Polarity,Short circuit.it will not drain your battery dry because of an under-voltage protection point.The Inverter does automatically sense overload condition and shuts down AC power when the load exceeds 500W.You will need to power Off/On to reset the overload condition indicated by the Flashing Red.The ON-OFF switch only works for the 3-prong plugs. - The 12V plug is spring-loaded and fits snugly into the receptacle.You cannot get 500 watts from 12volt cigarette lighter plug,needs alligator clips for car battery.

Fuse size, cable thickness?** A: The cigarette lighter plug supplied with the unit has a label attached cautioning the user that the load should not exceed 150W. If we assume that is 150W continuous with an allowance for a (small!) startup surge as any inductive loads energise, you're looking at a 20A slow blow fuse on a 12v circuit (you cold go with 15A, but that doesn't allow very much leeway). Cable thickness is harder to answer. As a rule of thumb, a current density below 5A/mm2 would demand 4mm2 cables as a bare minimum. For longer cable runs from your battery to the socket, about 1mm2 per metre of total cable length (that is, 0.5m out and 0.5m back) should keep your voltage drop to somewhere around 3% (of 12V at 20A). I suggest you check those numbers for yourself, though, because I am *not* a qualified electrician, and there may be environment/installation conditions or regulations which dictate different assumptions. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great *by M***N on 10 December 2025* Just right.

High efficiency *by M***N on 30 September 2024* Great little unit. Works brilliantly powering the 'sensitive' items I've tried so far, all using the 12v power plug.

Most of what i have bought includes purpose made solar generators which can be easily transported around the house. I have 3 fixed 200w solar panels and 1 flexible 200w panel which i move around the house dependant on the sun's location. Recently i had to replace my car battery and had the bright idea of trying to use the old 12v car battery as another form of solar power storage. This required me to purchase some additional equipment such as a MPPT charge controller and an inverter. I had a small 300w car inverter that i purchased years ago and thought i would see if it was powerful enough to power a 65" TV. I connected this to the car battery but it did not work, the TV immediately made a buzzing sound and i unplugged it immediately. I highly suspect this may be due to the fact it is not a pure sine wave inverter. I Therefore decided to invest in a small powered pure sine wave inverter - this Bestek had mixed reviews, with some saying it did not output a true sine wave, others however said it worked great. I decided to order and try it out for myself. . The inverter is bright pink in colour and comes with two crocodile clips connectors. The wires are a very thin gauge so i decided to up them to something more substantial. My TV draws around 60w in eco mode with a start up surge just over. The connections to the inverter are simple and straight forward with screw clamps. Once wired to the battery i switched on the inverter and it sprung to life. There is a built in fan which came on immediately even without any load attached - it is fairly noisy! Plugging in my TV the inverter provided the relevant power. There were no humming noises, nor was the audio or picture distorted, this brings me to believe that this inverter is indeed outputting a true sine wave. TV's and other sensitive equipment tend to not like modified sine waves and you will normally hear a buzzing noise. That did not happen with the Bestek. It all worked and i was chuffed! My only criticism of the bestek is the annoying fan noise, even at very low wattage loads the fan kicks in, after a around a minute the fan speeds up and becomes even louder - bearing in mind this was only pulling around 68 watts peak the fan seemed overbearing. We have this inverter in the bedroom and the noise of the fan is distracting, in a larger room you would not notice it as much perhaps. I have included a video review to let you hear the start up fan, towards the end of the video when a small load is applied you can hear the fan noise increase. Build quality wise, it appears good, aluminium chassis, decent UK 3 pin plug outlet, on/off switch on the front and two low powered USB A ports. Overall i am happy with my purchase - it does the job i wanted - i just wish the fan was 'smart' and varied according to need/heat rather than being always on. I hope that you found my review helpful. ## Frequently Bought Together - BESTEK 500W Pure Sine Wave Power Inverter DC 12V to AC 230V 240V with 4.2A Dual Smart USB Ports Car Adapter Red - Renogy 100W Solar Panel 12 Volt High-Efficiency Monocrystalline Module PV Power for Motorhome, Boat, Caravan, Campervan and Off-Grid Applications - Kohree 12 Way 12V Fuse Box, 12 Volt Blade Fuse Block Waterproof with LED Indicator, Automotive Box Holder 12V/24V with 30 PCS Fuses for RV, Car, Boat, Marine, Truck --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/216521570-bestek-500w-power-inverter-red](https://www.desertcart.tn/products/216521570-bestek-500w-power-inverter-red) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-17*
