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.

So easy and convenient for everyday bottle washing
I’ve been using these Momcozy washing blocks with the KleanPal Pro baby bottle washer, and they work exactly as intended. The tablets dissolve fully during the wash and leave bottles, pump parts, and accessories coming out clean with no residue or strong scent.
What I like most is the convenience. There’s no measuring or spilling liquid detergent, and each tablet is perfectly portioned. It makes the whole washing process quicker and more consistent, especially when you’re washing bottles multiple times a day.
They’ve been gentle on all of my baby items and haven’t caused any cloudiness or buildup on bottles or nipples. Overall, these are a simple and reliable refill to keep the washer running smoothly

Despite their size, they pack a powerful cleaning punch, leaving bottles sparkling clean and free of residue.
I love how convenient they are – just pop one into the washer, and you're good to go. Plus, the fact that they come in bags with many blocks ensures I won't run out anytime soon. If you're looking for a hassle-free and effective cleaning solution for your baby bottles, these Mom Cozy detergent blocks are a must-try!

A Game-Changer for Breastfeeding Moms!
I was a bit skeptical about buying a specialized bottle washing block at first, but I'm so glad I took the plunge! The Momcozy Official Washing Block is a total game-changer for breastfeeding moms like myself. This product has made my life as a nursing mom so much easier and more convenient.
First of all, let me just say that this block is SUPER easy to use. It's simple to pop in a dirty bottle into the machine, and before you know it, your bottles are sparkling clean and ready for reuse. The block itself is also very compact and lightweight, making it easy to store in my nursing bag or diaper bag.
But what really sets this product apart is its ability to get out even the toughest stains and residue. I've tried other bottle washing methods before, but nothing compares to the effectiveness of this block. My bottles come out looking like new every time!
The best part? The Momcozy Official Washing Block is affordable and makes a great investment for any breastfeeding mom. Trust me when I say that you won't regret buying this product!

Amazing
The Momcozy Bottle Washer Tablets have been such a great addition to our daily routine. As a busy parent, anything that makes cleaning bottles easier is a huge win, and these tablets really do the job well.
They dissolve quickly and help remove milk residue and buildup from bottles, pump parts, and other baby feeding accessories. After using them, everything comes out clean, fresh, and residue-free, which gives me peace of mind knowing my baby’s items are properly sanitized.
I also love how convenient they are. Instead of measuring or dealing with messy liquids, you simply drop a tablet in and let it work. It saves time and makes the whole process much simpler, especially during those busy days and late-night bottle cleanups.
Another plus is that they seem gentle but effective, which is important when cleaning items used for babies.
Overall, these tablets are easy to use, effective, and a real time saver. I would definitely recommend them to other parents looking for a simple and reliable way to keep baby bottles and feeding supplies clean. I will absolutely be purchasing them again! ✨
