Readers can expect an in-depth description of the product’s features, user opinions, reviews, videos, comparisons, and attractive market offers for the product.
- Introducing the BESTEK Power Inverter: As America’s first power inverter brand, the BESTEK power inverter delivers 500W of continuous DC to AC power and 1000 watts of peak power. It is equipped with 2 AC outlets and 2 USB quick charging ports, ensuring versatile and reliable power conversion for your needs.
- Robust Charging Capabilities: The inverter features dual 110V AC outlets, ideal for powering larger devices like laptops, tablets, and household appliances under 500 watts. Additionally, the 2 smart USB ports (0-2.4A) cater to your USB-powered devices, making it a perfect choice for camping, outdoor adventures, or road trips.
- Comprehensive Multi-Protection System: The BESTEK power inverter includes built-in 2*40 amps fuses, providing robust protection for your devices and battery. Its safe charging technology safeguards against overheating, under/over voltage charging, overload, and short-circuiting.
- Efficient and Quiet Cooling: Featuring a smart cooling fan, the BESTEK power inverter adjusts its rotation speed according to the power load and temperature. This intelligent design minimizes noise while protecting the inverter from overheating with its high-speed cooling capabilities.
- Convenience and Reliability: The package includes a car cigarette lighter plug (27.5 inches) and a pair of alligator battery clamps (24 inches) for easy connection to your cigarette lighter or 12V battery. Additionally, you receive 2 spare 40A fuses, an 18-month warranty, and friendly 24/7 customer service support.
Since its establishment in 2007, BESTEK has been dedicated to innovation in the realms of power inverters and household appliances. Their range, which includes power inverters, power strips, voltage converters, and travel adapters, ensures that users stay connected and powered up, whether at home or on the go. With the BESTEK 500W Power Inverter, users have a reliable companion for road trips or outdoor adventures, keeping essential gadgets charged and ready for use. This model is particularly suited for major brand laptops and digital devices like video camcorders, iPads, and cell phones.
The product boasts a robust aluminium alloy exterior, designed to withstand various environmental challenges, protecting its intricate internal components. Equipped with multi-protection features such as input over-voltage and under-voltage protection, and output short-circuit protection, users can rest assured their devices are safe. The inverter includes dual smart USB ports that automatically detect device requirements, delivering optimal charging currents up to 2.4A per port, ensuring fast charging without compromising safety.
For maximum power output, users should connect the inverter directly to their vehicle’s battery using the included alligator clamps. By doing so, the inverter efficiently supplies up to 500W continuous 110V AC output. However, when connected through a vehicle’s cigarette lighter socket, the power output may be limited to around 150W, due to circuit constraints. This ensures the vehicle battery doesn’t drain unexpectedly, adding a layer of security. The package comes with additional 40A spare fuses, ensuring longevity and user convenience. For seamless power solutions, let the BESTEK power inverter be your trusted choice.
This item works great, and is great value for the money. It can be installed several different ways, BUT BE WARNED. Even when turned off this unit draws a small amount of power. I have it installed in my convertible to power laptops when traveling. But I learned the hard way, that if I go more than about 10 days without driving it, the battery will be dead. So I installed a relay that disconnects it from the battery when I turn the motor off. No issues since.
Update 01/21/2024 BESTEK reached out to me about my experience and are working on making it right. I may have not had a good experience with the product, maybe I got a lemon but I appreciate BESTEK reaching out to make it right. That is good customer service that I don’t see much these days. Even though it died on me I changed my rating from 1 to 3 stars because of their customer service. The customer service makes me willing to try this product again. —- When it worked it was good but unfortunately it died after a month. Not a month of continuous use, only sporadic use. It is mounted to a wall so it’s not like it was getting jostled around. I’m not sure why it died. I was trying to avoid the cost of a morningstar inverter and it’s competitors but I should have just grit my teeth and spent the money. If this one is working for you awesome. My experience is that going cheap has cost me money instead of saving it.

Inquiries & Responses: Your Doubts Clarified
What devices can I power with the BESTEK 500W Power Inverter?You can use the inverter to power a wide range of devices such as all major brand laptops, digital cameras, iPads, iPods, cell phones, PSPs, DVD players, and other digital portables. Essentially, it can power any device that requires up to 500W.
How does the BESTEK power inverter protect my devices?This inverter offers multiple protection features, including input over-voltage, under-voltage, output short-circuit, over-load, over-current, and over-temperature protection. It also provides full isolation voltage protection and contains built-in 40A fuses that safeguard your devices from potential damage.
Why does the inverter output less than 150W when using a cigarette lighter socket?The cigarette lighter socket in most vehicles has a circuit limitation with a fuse rated at less than 10A. Consequently, the maximum AC output through this connection is around 150W. For higher power output, it’s recommended to connect the inverter directly to the vehicle battery using the included alligator battery clamps.
What’s the advantage of having dual USB ports on the inverter?The dual USB ports are designed to automatically detect your devices and deliver the best-matched charging current for fast charging. Each port can provide up to 2.4A, with a total output of 5V 4.8A, allowing you to charge multiple devices simultaneously and efficiently while on the go.
How do I connect the inverter to a vehicle battery for maximum output?To achieve the maximum output of 500W, you need to connect the inverter directly to the vehicle battery using the included alligator battery clamps. This bypasses the cigarette lighter socket’s limitation, providing a more robust and consistent power supply to your devices.
Is the BESTEK power inverter durable and suitable for outdoor use?Yes, the inverter’s outer shell is made of aluminum alloy, making it both solid and durable. It is designed to withstand various harsh environmental conditions, ensuring the internal components remain protected. This durability makes it ideal for both indoor and outdoor usage.
What should I do if the inverter’s built-in fuse blows?If one of the built-in fuses blows, you can easily replace it with one of the two spare 40A fuses included in the package. This is a straightforward process detailed in the user manual, ensuring minimal downtime and continued protection for your devices.

For some reason the red is noisy while the gray is not
No problems. Reliable.

Not 500 w highly misleading
It can barely handle 352 although it says it’s rated for 500 it does not do it. What’s the proper gauge and length wire and backed by 12.8 v 100 ampere lipo4 it failed 500 watt test it failed the 400 watt test it barely made it past 350 Watts

Didn’t work out of the box.
Even connected by the supplied power cable directly to a fully charged 12v battery (tested 12.5 volts) it showed a low voltage error (green light flashing) and would not work. I returned it and bought a different brand.

Works great!
We put this on a solar system in one of our deer blinds. Worked out great. Runs a ceiling fan and mini fridge and we can charge phones etc!

Outstanding Customer Service!
The inverter works good, but unfortunately the two USB ports quit working after about 9 months. I contacted Bestek customer service and they asked to see a video to show them the defect, or maybe tell me how to fix it. I sent them a quick video and my new replacement inverter arrived the next day. I highly recommend this inverter because it’s good, and customer service is excellent.

not producing 110v.
This unit is only producing a weak 106v. . . .which will damage most sensitive products.
Matthew –
Great price for 500W Inverter
We needed 110V power for our camper during off grid outings. We just needed to charge laptops and phones, run a small fan – little stuff. this little number does the job. It is quiet and cool. Under 50 bucks – sweet!

After almost 5 years of constant use and abuse and storage outdoor. Here is my real review!
Where do I have to start??! This thing truthfully is amazing piece of invention. It’s highly durable. I know because I tested it in multiple cars I got crashed pretty hard, stored in very high temperature above 130 degrees F at one point. It even gotten rained on. Yet it still charging really good. I have no issues charging small appliances and multiple electronics with this inverter. It’s always been kept on the top of my work car dashboard directly exposed to hot California and Arizona Desert sun. All but one USB works. Fuse still original and as you can see. It definitely got serious aging. Rust buildup because of sun and occasional rain exposures. Also cables started to get worn out but it still working. I gave 4 star because I don’t know where I can get purchase or get a replacement wiring for this little beast. would I recommend buying it. TOTALLY!! it may not be on the cheaper side. But it definitely feels durable, it’s none like the other cheap plastic inverter you see online. It’s made of metal casing and felt rugged. No noise issues om mine.

Served it’s purpose
Worked for what I needed it to. Ended up giving it to my brother and he put it to use. His wife even used it to breast pump in times of need. Unfortunately after a little over 3 years it stopped working.

Awesome customer service!!
I had a problem arise with my power inverter and I reached out to Bestek. They responded in a timely manner and resolved my issue.
Chris Caldwell –
Great solution for power while traveling
I do a lot of work on the road and need to recharge batteries, power a laptop and phone, and sometimes even video lights. I have the 300w version and loved it, wanted more power and the option to mount it, so I got the 500w version. They are both built like tanks, don’t get hot, and are really easy to use. The USB also makes it nice to still be able to have my phone plugged in after this takes the 12v plug.
StarrmanGL –
Works as advertised!!
On time delivery, easy instructions to follow, worked right out of box!!
Omar Moreno –
Super reliable and priced good
I bought this about four years ago and it’s still good and as close to new as it can be. I’ve used it on and off for my business many times and it’s still going strong. Good quality, good price and good equipment; highly recommend.

Was great, until it stopped working.
Everything was fine until it wasn’t. Checked all fuses and connections. The inverter just crapped out after a few months. Sucks.

Problem Resplved
Update 01/24: Seller responded and apologized and offered and provided a prompt refund. Very pleased with customer support and now I will buy from them again. This is all I can ask and expect, as sometimes products do have issues. The important thing is how sellers handle them, which in this case was great. Although they do need to get their phone line working. Thanks ———- I’ve purchased this exact same item (albeit in red) numerous times before and have had no problem running my 24” Philips LED TV in my RV – which used 50W max when on. Yet this one trips and causes red light to come on and shuts down when I turn it on. Not happy at all! And I’m about 30 days outside return window because I’ve been out of town and just had first opportunity to try it (unboxed it yesterday). Seller will not reply to calls, even from Amazon Support. I want a refund asap – as I am about to depart for long camping trip (so I can’t return it after that, at least not for at least a few months). When the other units failed after a year or more of use, I could accept that. But not this. Definitely defective from outset. Bestek, please contact me asap, and if you resolve the matter to my satisfaction I will update this review accordingly.

Small but has lots of power
We use it to jump start the tractor after it sits for a little while.

Good to have a plug around
My truck does not have a 110 volt plug, so this inverter is great to have around for when I need a 110 plug for something and I am in the middle of nowhere. They are only 500 watts, so they won’t power everything but they sure have come in handy.
Lora Barshow –
Works as advertised
I’ve used three besteks over the last ten years. They all work just the way you’d expect. Good value with this brand.

Good for Starlink
Good little inverter that powers my 110vac Starlink from the boat’s 12v system. It is easy to mount and connect. This allows me to run my data network during power outages.

Mechanical defects of the product can haunt buyers!
The most serious mechanical defect of this product is that some of the units, if not all, will knock out the fuse of your car’s cigarette charger/outlets within seconds, whether the units’ output power is for 300W, 400W or 500W. The website description has no mention of it, and the overwhelming majority of the reviewers who gave this product negative one-star comments had complaints exclusively on this issue. Does the manufacturer give any quality test for the product? If you do not know how to change the car’s fuses on your own, the repair cost and your precious time to be spent to fix the trouble at an auto shop will surely anger you. Why should the buyer bear this extra burden as a result of the product’s known(!!) mechanical defect? Value for money? I’d give negative 5-stars!
Susan Hauck-Wasiewicz –
great for dry camping
The compact design makes it easy to take anywhere. I use this until I have the solar panels up at camp. Nice to have another source of power when needed
Mickey93 –
It’s Red
I have a SAE line coming into the my truck bed to power accessories. I bought this unit because it has terminals. So I bought a short SAE cable to terminals and wired up my inverter. The wires almost melted immediately. Why did it get hot, and not even turned on? Well my wires came with a little reverse adapters I didn’t pay attention to, and when I plugged in the SAE connector is was hot to ground. I added the reverse adapter and problem solved. Whew. I plugged a light in, and it turned on. The piece feels rugged, and looks good. Time will tell how it holds up to occasional use.

WARNING: only supplied 99v
Be careful. My unit only provided 99V. My fault that I didn’t test it first, but it burnt out my Sleep Number mattress pump before I realized what was going on. Make sure you test the voltage before plugging a device into it, it can brown out and damage your electronics.

Works great
To run starlink and charge laptop at same time in truck.

Great for us
Bought this to use for powering our portable Traeger while camping and tailgating. I was very impressed with the quality and performance.
Battery –
Very well built!
I true find. Very well built. Thick wires, big connectors, excellent paint job 🙂 Quiet at 330 watt load for a couple of hours running a gaming laptop, while charging it. Really happy I stumbled on this brand. Seems like they put pride in their work.

Great for smaller plugins
We use this when doing primitive camping our tailgating. Super easy to connect and use. Note: You can’t plug in higher power items, so research what you plan to use it for.
