When your vehicle battery voltage is under 11V, it will trigger input under-voltage protection, this will protect from draining your vehicle battery. Spare Fuses Built in 2*40A replaceable fuses, protecting your device from over-current, over load damage. 2 pcs of spare 40 amps fuses are included in package. Review: Good little inverter - I bought this to use in a show van to light up a few table lights . Due to the fact that I will only be using it for lights I decided that the less expensive 500 watts “non sine wave” would be fine for me. I am using a four foot extension lead and plug the lights into and It works well . I am using 3-4 watt led lamps in each of the lights and the inverter is performing as it should and lighting up the back of my showroom van . It feels sturdy and well built the 13 amp plug socket feels solid As does the cigarette socket too. Overall it feels like a good purchase and I would recommend it. Review: Cost effective and efficient - Runs almost silently, easily mounted on any wooden surface and works as expected. A little smaller than I thought it would be but that is a bonus in a Campervan ## Features - 【Bestek’s power inverters #1 power Inverter brand.

A little smaller than I thought it would be but that is a bonus in a Campervan ### ⭐⭐⭐⭐⭐ Great product for generating mains voltage from a 12V battery *by R***J on 23 December 2016* Great product that I'm using to run a mix of flourescent and (mains powered) led lights in remote stables using solar power and a battery. The load is currently only 170 watts but the spare capacity allows for expansion of the lights and other uses. I still need to check the current being drawn if the unit is left on when not in use but, contrary to what I have read, I would highlight that the cooling fan doesn't run all the time if there is no load. As my lights are switched via a light switch then if the lights are off then the fan stays off and comes on as soon as I switch the lights on. The load can be applied while the invertor is switched on, it just goes through a slow start-up which is not noticeable other than the led on the invertor goes from red to green. I did run my battery down at one point and found that the unit had it's one LED on probably indicating a battery undervoltage. The unit seems to be of good quality although I did note that the neutral terminal on my invertor turns slightly so I assume is not tightened correctly within the invertor but it's working okay and I didn't want to take the unit apart to investigate. I would also point out that if you plan to draw the 600W that the invertor can supply.then you will need good sized cables for this to minimise power loss, I used 16mm cable as I needed a 1.5 metre run from the battery. With a 600W load you will be drawing 50amps from your 12volt battery and the supplied cables looked rather thin for this. You should also note that you won't get very long operation at this load from a 100Ah battery and more importantly you'll need a good set of solar panels to keep the battery charged in winter when you need lights the most. I have not used this to power any motors such as fans as you will see from other reviews that this is NOT a pure sine wave generator (ie like our mains power) , but a modified sine wave wave (basically a square wave) and so motors may tend to run hot. ## Frequently Bought Together - BESTEK 500W Car Vehicle Power Inverter DC 12V to AC 230V 240V Converter Car Charger Lighter Adapter with Dual USB Ports - ULTRAMAX 36 HOLE 22A Slim fit Lithium Golf Battery Set, perfect for PK, MotoCaddy, GoKart --- ## 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.kr/products/127419848-500w-inverter](https://www.desertcart.kr/products/127419848-500w-inverter) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-07-04*
