REVOLUTIONARY MODULAR CHEMICAL APPLICATION

The Milwaukee 3019-21PS M18™ SWITCHTANK™ system is a game-changer for facility maintenance and landscaping professionals, engineered to eliminate the physical strain of manual pumping while solving the logistical nightmare of cross-chemical contamination. By utilizing a modular architecture, this system allows users to swap dedicated tank assemblies for different chemicals in seconds, ensuring that herbicides, pesticides, and fertilizers never mix. Driven by the M18 REDLITHIUM platform, it delivers consistent, high-pressure performance that traditional pump sprayers simply cannot match, providing a massive boost to fleet productivity and site safety.

  • / SWITCHTANK INTERCHANGEABLE DESIGN / Isolate chemicals by swapping tank assemblies, eliminating the risk of residue contamination and increasing asset utilization.
  • / INSTANT CONSTANT PRESSURE / Achieve up to 120 PSI with no manual pumping required, drastically reducing operator fatigue and ensuring uniform coverage.
  • / 5-MODE ADJUSTABLE DIAL / Fine-tune the flow rate and pressure between 20 and 120 PSI to suit everything from delicate botanical misting to high-reach vertical applications.
  • / 20FT VERTICAL SPRAY DISTANCE / Power through demanding exterior applications with enough pressure to reach second-story eaves and high foliage.
  • / CRITICAL COMPONENT PROTECTION / Integrated Viton seals at key points provide enhanced chemical resistance and long-term durability in harsh environments.

Great & very convenient charger, only one issue
Color: 2Black
This charger wound up being everything I hoped for - it charges a Galaxy S26 fast and works with a wireless charger compatible phone case. Despite all this, I'm taking a star off for the fact that *you have to buy an aftermarket converter* for it, because for some ridiculous reason, its cable end isn't a USB type A (which your previous phone's converters and probably many of your home's outlets use), but requires a 30W (no less) USB-C. So, there goes another $10 for the converter. Actually you'll probably want to buy two, for at least two rooms at your home, so there goes another $20.

Absolute trash.
Color: 2White
Neither charger worked on arrival... Quite disappointed. Now I'm steering away from every item that has the same markings. Just shelling out for a better quality charger... Not worth it at all... It's incredibly irritating having 2 DoA chargers... Tried on 5 different phones and 10 different blocks.

Charges slowly and makes phone/charger really hot.
Color: 2White
I thought these would be great, but they aren't. I use them with a 25w charging block, but they charger my iPhone so slowly! I can't really use the phone for any games or even scrolling TikTok while the charger is on it because the phone uses power faster than these mag-chargers can charge the phone. The phone also overheats when this charger is on it. Never had that problem with a lightning charger. Basically these are only good when you won't be using the phone, and it takes a long time. Not very happy with them.

Secure Mount With Premium Feel
This phone mount feels incredibly sturdy once installed. No shaking or movement while driving, even on rough roads. The design looks clean and factory installed instead of bulky like a lot of other mounts. It holds the phone securely and keeps it easy to access for navigation.
