Review: Works well for the price. - Works good enough for my device that draws 55watts of power in my van while driving. Pure sine wave help keep it quiet while running as well. Last unit had a modified sine wave that made the device motor extremely noisy. It is a little larger than expected but not an issue at all. I won't be testing it out with more than maybe 70 watts, so I don't know if it can handle the claimed 300w or not.
Review: Power Inverter seamlessly transforming my car into a mobile power station - The BESTEK 300W Power Inverter is an absolute essential for life on the go, seamlessly transforming my car into a mobile power station. Its greatest strength is the pure sine wave output, which provides clean, stable power identical to a home wall outlet. This means I can confidently and safely charge sensitive electronics like my laptop, camera battery, and premium headphones without any risk of damage or the humming interference common with cheaper modified sine wave models. The convenience is unmatched. The unit plugs directly into the 12V socket, and the two AC outlets and two USB ports allow me to power multiple devices simultaneously during road trips or while working remotely from my vehicle. It has effortlessly handled everything from a small fan to charging a CPAP machine for a camping trip. Compact, reliable, and incredibly efficient, this BESTEK inverter delivers professional-grade performance in a user-friendly package. For anyone who needs trustworthy AC power away from home, this is an invaluable and highly recommended investment. It simply works perfectly.

## Questions & Answers

**Q: Can this unit support metrovac vacuum 120v - 60hz - 11.25amp?**
A: No, absolutely not. 120 volts at 11.25 amps is 1,350 watts, that's only 1,050 watts more than the 300 watts this unit is rated for.

**Q: how many amps can this handle safely for long periods of time? ( to anyone who knows or the seller) thank you!**
A: Rule of thumb for constant use and keeping things safe with as long as possible lifespan is about 66% of what it's designed for. This gives headroom to the voltage rails and tolerances. When electric components are used at their full capacity they heat up. So run at lower ratings to keep things cool without the fan having to overwork itself (which is just another potential failure point).

So for something rated at 300W I would try to keep continuous wattage at 200W. You're always going to have peaks and spikes, voltage drops and resistance, etc that will eat up the head room regardless so keeping continuous wattage usage lower at around 66% is ideal for pretty much all power supply needs including power amplifiers.

So whatever it is that you need to run constantly, take the continuous wattage and multiply it x1.5 and look for an inverter that has that continuous wattage rating to keep things longterm safe.

**Q: Does it automatically shut off if the battery drops bellow a voltage?**
A: The reason I am here today looking at reviews and deciding on a new inverter is because mine has stopped working after the battery dropped. I connected it to a different battery and it works for a couple of minutes and then 120V drops for a few seconds, in a repeating cycle. So my unit has failed after battery voltage ran out.

**Q: What is the length of the cord that plugs into the lighter outlet?**
A: Did the unit come WITH the cord, or do you have to purchase that separately?

### ⭐⭐⭐⭐⭐ Exceeded my expectations
*by S***. on May 14, 2025*

First: A big thanks to all of the Amazon Reviewers leaving detailed and technical reviews of this product! I've been considering an inverter for use on long road trips for years now. This spring, I purchased a car equipped with wi-fi. This kicked my consideration into serious shopping mode. I wanted to use my work laptop to accomplish things from the passenger seat. I looked at Dell's online shop and what they had that was compatible with the laptop. I then came to Amazon for the reviews of that model. Not great. Reviewers were mentioning that you need a Sine Wave inverter for laptops. Based on that information, I switched my amazon search to include that term and I stumbled upon this device. I purchased this inverter based on the thoughtful and detailed reviews from purchasers who know more about the technology than I ever will. It performed beautifully and did not even get warm to the touch. I used my laptop twice over our 6.5 hour journey. Once for approximately 3 hours while I took mandatory training though work's learning center. The second time was to respond to emails and fix a few documents and took about an hour. The USB ports ended up being a much needed benefit to this device. This was our first road trip in the new car and my husband (while setting up & testing the inverter) discovered all of the car's charging ports are USB-C (aside from the one cigarette lighter plug in the behind the center console). The car does have a magnetic charger but his phone case does not have a compatible case. We have since ordered USB-C to USB-C charging cables. Over the course of the 2 way trip, we used this device to power 1 Dell Latitude 5420, an iPhone 12 Pro Max, and 1 Kindle Fire. I'm very happy with the performance and thrilled I can work from the passenger seat instead of burning a day of PTO while watching cornfields go by.
