The Mastervolt AC Master power inverter produces a pure sine wave AC (Alternating Current) output from a DC (Direct Current) input from your boats battery bank. Because of the pure sine wave output, it is safe and reliable and prevents damage to the equipment it is connected to. The inverter is easy to install and features built in protection against over-temperature, overload, short circuit and high or low battery voltage. The power inverter is robustly built and delivers the full output even in demanding conditions. The high frequency technology used eliminates noise typically associated with power inverters, such as buzzing or humming. It also features an automatic power saving mode, meaning a longer run time and less strain on your batteries.

Comfortable and stays cool
Color: White-cooling Basic, Size: Queen(Pack of 1)
Great pillow. When i opened it, i noticed a strange smell, i assumed its the smell of whatever they use to make the pillow stay cool. You have to fluff it for a good amount of time to make sure the cooling agent spreads well in the foam. Is what i assumed atleast. Its a perfect amount of softness for me. Pair it with some bamboo pillow cases and you got a good night of sleep

Comfortable and Supportive, but Adjust the Filling
Color: White-cooling Basic, Size: Queen(Pack of 2), Color: White-cooling Basic, Size: Queen(Pack of 2)
I’m very happy with this pillow. The size is big and it feels soft while still providing good support, perfect for midnight scrolling on TikTok.
One thing to keep in mind is that it can feel a little too tall if you use all of the filling that comes with it. The good news is that you can easily adjust the amount of filling to find the height that works best for your sleeping position. Once I customized it, it was much more comfortable.
Overall, great quality, comfortable, and worth the purchase.

BEST PILLOWS EVER!!!
Color: White-cooling Basic, Size: Queen(Pack of 2)
I am very picky with my pillows because I have a bad neck and I can never seem to find a good pillow. But I tried this pillow because it had everything I was looking for and the price was great! You get two of them and they are absolutely awesome.! normally I would need to lay on two pillows to try and get comfortable but with these pillows I just lay on one and I wake up with no neck pain. They really have a nice cooling effect. They actually puff up immediately after opening them. All you have to do is just shake them up and the pillow just puffs straight up.. It comes with extra cushioning if you want it to make it firmer and if you don’t want it as firm as it is, you can actually take some out. It really is such a beautiful pillow. It’s perfect in every way to me being such a picky pillow person.
You just lay your head down on it and it forms around your neck and your head and when you get up, it goes right back to its normal form. It doesn’t get flat and I love it. I completely recommend this to anyone who is a person who has a hard time finding a really good pillow.
