Reliable, Pure AC Power for Demanding Applications

Experience stable, clean, and reliable AC power wherever you need it with the Mean Well NTS-450-224UN. This 450-watt power inverter is engineered to convert 24V DC power from batteries into high-quality true sine wave AC power, making it ideal for a wide range of applications. From off-grid solar systems and vehicles to mobile devices and sensitive electronics, the NTS-450 delivers consistent performance you can trust. Its digital design with MCU control ensures a rapid response to environmental changes, enhancing reliability and performance.

True Sine Wave Output for Sensitive Electronics

Unlike modified sine wave inverters, the NTS-450 produces a true sine wave output with less than 3% Total Harmonic Distortion (THD). This clean and pure waveform is crucial for powering sensitive electronics such as laptops, TVs, communication equipment, and power tools without the risk of damage or interference. The high surge capability of up to 900W ensures that even devices with high startup currents can be powered on without issue.

Built for Durability and Efficiency

Engineered for performance, the NTS-450 boasts up to 93% efficiency, minimizing power loss during conversion and maximizing the runtime of your battery bank. It operates across a wide temperature range of -25°C to +70°C and features a temperature-controlled cooling fan for optimal thermal performance. For added convenience, the AC output voltage and frequency are selectable via a DIP switch to match regional standards. A comprehensive set of protection features, including input reverse polarity, DC low shutdown, overload, and short circuit protection, safeguards both the inverter and your connected devices.

Key Features:

  • 450W Continuous Power with 900W Surge Capability
  • True Sine Wave Output (THD <3%) for clean power
  • High efficiency up to 93%
  • Wide operating temperature range (-25°C to +70°C)
  • User-selectable AC output voltage and frequency
  • Comprehensive protections for safety and reliability
  • Suitable for lead-acid and li-ion batteries
  • Compact and lightweight design

These are not sized correctly - beware
Color: Blue-ice Plus, Size: King(Pack of 2), Color: Blue-ice Plus, Size: King(Pack of 2)
Edit: I was going to return these pillows but the seller contacted me and offered a full refund due to the size issue without having to send the pillows back. I am happy with this and happy to keep them on a spare queen size bed as they really are nice pillows. Just the wrong size. pros: they are a nice pillow and the cooling feature is really great, and you can adjust to your liking cons: absolutely wrong size. Ordered King, tag says king, all measurements on listing and tag say 20x36, in reality they are more like 20x30. Definitely Queen pillows being sold as King. I did not see any reviews at first about size issues but after I got these and did a search it does look like others have had the same problem. A shame, would have given them a great review if they were the correct size

Really Good Cooling Pillows for Sleeping
Color: Blue-ice Plus, Size: Queen(Pack of 2), Color: Blue-ice Plus, Size: Queen(Pack of 2)
These cooling pillows are very soft and provide excellent support for your head and neck. They are adjustable by taking our the stuffing if you need them to be more flat or less firm. The look great and comes in a pack of two which is a great value. During use, I did notice they have great shape retention and it does not take them long to return to their fluffy full shape. I am a hot sleeper and these do keep your head cool - just be aware using a pillow cover does reduce the cool ability but this allows you to adjust for weather like during winters to add a pillow case for extra warmth. Very happy with this purchase and got a second set to replace my old pillows.

Amazing - Stop Scrolling and Buy This Pillow
Size: Queen (Pack of 1), Color: White
I have been an Amazon customer ever since the very beginning, and this is my first review. Not because I haven’t purchased tons of amazing things (and a few bad ones), just never felt the need. However, I researched pillows for longer than I care to admit, and decided on this one. I’ve had it for about six months and absolutely love it. No lie, I genuinely look forward lying my big head on it after a long day. I am a side sleeper, but flip flop all around through the night and it’s great in every position. Pros: Stays nice and cool, which is soothing regardless of the time of year. Has a sort of quilted textured pattern on the zip up cover, gives it a luxury feel, that breaths nicely even when a pillow case is added. The fill is fully adjustable to your preference. I knew it came with extra filling but was worried it would not be enough. Wrong. It was very full and I ended up taking some out until it was perfect. It comes vacuum sealed and suggests it may take some time to fully take shape. However, I found it to be about 90% almost instantly and was sleeping on it a couple hours later. There was no unpleasant scent sometimes associated with memory foam items. The foam itself is very nice, a mix of what appears to be shredded and cotton candy cloud like. Very brilliant idea, as it is somehow supportive, soft and firm all at once. The affordability of this pillow compared to some of the others in this category can’t be overstated. Oh, and the packaging was very thoughtfully and securely done. If you are like me, an over thinker, I would suggest just taking this for a spin. It’s amazing. I’m not a bot, or working for the company. I’m just truly satisfied, love this pillow, and have been sleeping great.

It's the perfect pillow!
Size: Queen (Pack of 1), Color: White
I purchased this pillow specifically for its customizable fill feature, which allows you to add or remove stuffing to suit your personal comfort needs. Due to the unique curvature of my cervical spine—forward at the neck rather than backward—I require a soft, semi-flat pillow rather than one that is thick or firm. Additionally, I often experience ear discomfort by morning, so a gentler surface is essential. Upon adjusting the fill, I was pleasantly surprised by the generous amount of stuffing included. There was enough to fill an additional pillowcase, and I estimate it could easily create four to five more pillows. The ability to modify the pillow’s firmness at any time is an outstanding feature that makes it adaptable for a wide range of preferences and sleep styles. This pillow has exceeded my expectations in both comfort and versatility. I highly recommend it to anyone seeking a personalized sleep experience.
