Monster 150Watt Power Inverter with Dual Port USB 20W USB-C, QC 3.0 USB-A: Car-Powered DC Inverter, 6ft Cord, Red/Black

I purchased this inverter mainly because it is advertised as having a 6ft cord. After unboxing I was extremely frustrated to find a cord that is only 2.5ft long. I will be returning to get my $ back.

It will serve it's purpose

When it was working, it was great. It charged everything super quick but it only lasted a week for me. Not worth it in my opinion. Try a different brand.

Only lasted a few weeks. Maybe an hour of total use, before it stopped working. I bought the extended warranty through Target and have been trying to get it replaced for 2 months. The company won’t respond at all.

Item does not work with laptop. Complete waste of money

Monster 150W Car Power Inverter with high hopes of having a reliable charging solution for my devices during road trips. Unfortunately, my experience has been far from satisfactory. Upon receiving the inverter, I noticed several glaring issues. The most critical flaw was a broken wire that rendered the inverter useless. The wire was visibly damaged, and no amount of troubleshooting could revive it. Without a functional wire, I couldn’t charge either my laptop or my USB cables, defeating the entire purpose of having an inverter in the car. To add insult to injury, there was no indicator light to confirm whether the inverter was turned on or not. As a user, I rely on visual cues to know if my devices are receiving power. The absence of this basic feature left me frustrated and uncertain. The overall build quality is disappointing. The lack of attention to detail in the manufacturing process is evident. A broken wire and missing indicator light are signs of poor quality control. I expected better from a brand like Monster, known for its audio and power products. In conclusion, the Monster 150W Car Power Inverter has left me thoroughly disappointed. It fails on multiple fronts: functionality, durability, and design. I strongly advise potential buyers to steer clear of this product. Invest in a more reliable inverter that won’t leave you stranded on the road with dead devices.

This is a very well built power inverter with AC power outlet and dual USB port. It also has 20W USB-C port for fast charging. It has a strong aluminum busy and very durable. I recommend it to others .

So excited to try out this Monster 150W Power Inverter with 20W USB-C charging AC power outlet + Dual USB port. It's made from aluminum and is pretty sturdy. Plug into your vehicle's cigarette lighter and power up to 3 devices. One AC outlet, 1 USB-A port and 1 USB-C port are available on the Power Inverter. Run and charge your laptop, phone, and tablet all at the same time. There's a fan that runs while the Power Inverter is in use to prevent overheating. It has an on/off switch which is great so you don't have to unplug it to turn its power off. Overall this is a very useful device that I'm glad I have now. Highly recommended.

I received this item in exchange for my honest review. This 150 watt power inverter by Monster is perfect for road trips, camping and picnics. I have used it to charge my laptop and iPad on the go; it has been a perfect alternative power supply for my needs. Camping has been much easier with this power inverter; we use it to plug in our portable refrigerator, fan and light that use a 110V AC plug in. The unit has three ports, a USB, C and AC that makes on the go charging and powering a breeze! The unit is compact and easily portable/storable. The on/off switch is a great feature that allows me to power down, while leaving the unit plugged in and ready for use. I will get a lot of use out of this lil monster. I would recommend it for my family and friends that are frequently on the go.

This item plugs into the old cigarette lighter style charger port, it is not powered by usb (I have a 2022 vehicle which is equipped with this style charging port, so the unit DOES fit newer vehicles). When powered on, the unit does make minimal noise as there is a cooling fan inside. I was able to power/charge two cell phones at a time without any lag in charge power and was also able to power/charge a notebook laptop. Would definitely recommend item.

I have mixed feelings about this product. I plugged it into the cigarette lighter in my car and then used my cell phone cord to plug into the USB port to charge my phone. The good news is that it seemed to charge faster than when I plug it in at home. The bad news is that my phone felt hot. This charger also has a fan that is pretty loud. It actually startled me a bit when the fan started running.

Power adapter for the car with three different options. Very heavy duty. A bit bulky to have in the front console, but for a long trip where you want multiple plug options, it would be good. I always want a regular plug during trips.

This product is perfect for the car. It not only provides phone charging capabilities but also allows for an outlet. The cord is really long (a good and bad thing) - it can reach the back seat but then you have a cord potentially in your way. It was also neat that the charging port had and on /off switch. So glad I have this.

I needed a new car charger and tried this because it isn't limited to just my phone and will let me plug in a laptop or other electronics, too. I love that it has both the standard plug, USB, and USB-C. I tested it with my phone charger first and the charging was faster (according to the time remaining till full charge shown on my phone) using instead the USB. The device's cord was fairly long as shown in the picture so it could probably stretch to the back half of the car but not to a backseat. I liked that the cord had a velcro strap attached to make that storage easier. The device does make a slight buzzing sound and you can hear, less loudly, the whirring of air. I wish it didn't make the buzzing sound, though with my radio on I didn't notice it.

This is a very compact and useful power inverter to quickly charge a variety of devices including iPhones, iPads and laptops. Lighter plug for the car and several outlets available for charging on the go.
