Works great by the way... **Q: Could this be used to add distilled water too, say drawing the water out of a cup? Looking for multifunction instead of buying tester and filler.** A: Do NOT buy because MIGHTY MAX is selling it, they are a rip off company who only takes other peoples items and rebrands them to resell, they have NO CUSTOMER SUPPORT, the BATTERIES THEY SELL ARE JUNK TOO. **Q: How do I read it no marks on large tube ?** A: Read at water level on the inner float. **Q: What exactly is the difference between the car, boat/marine, and golf cart models?** A: Car. Boat.marine all have starting capacity of 100 amps a golf cart use is about 30 to 40 amps. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works. *by K***N on January 8, 2026* This worked really really well.
