Description
MPPT 40A 12V/24V LCD Display Solar Controller Automatic Identification Off-Grid System Controller1. Adopt DC DC conversion technology and MCU technology. It can intelligently adjust the working point of the solar panel array, so that the solar panel array achieves the maximum power output. When external conditions change, the MPPT controller tracks the maximum operating point of solar panels based on MCU theory, so as to improve the efficiency of solar panels and reduce the cost of solar power generation. Compared with ordinary solar charge
1. Adopt DC/DC conversion technology and MCU technology. It can intelligently adjust the working point of the solar panel array, so that the solar panel array achieves the maximum power output. When external conditions change, the MPPT controller tracks the maximum operating point of solar panels based on MCU theory, so as to improve the efficiency of solar panels and reduce the cost of solar power generation. Compared with ordinary solar charge controllers, MPPT can increase the output efficiency of solar panels by 5% to 30% (the rate of increase in output is affected by the attributes of solar panels, ambient temperature and lighting conditions).
2. LCD liquid crystal display, USB output, the product can charge various lithium batteries, activate lithium batteries, etc.

Truly indestructible
Size: Large, Color: Blue
They are not kidding, this ball is truly indestructible. I've gotten several for my dogs so they have plenty to share. Two of my dogs are beyond super chewers (bully breeds). One of the balls is missing the section that's glued into most of them, but the structure has still held up. And my dogs LOVE them.

Tough STINKY ball
Size: Large, Color: Red
This ball is the only one I've found that my dog can not destroy in seconds. He can chew on it for a few weeks before he works a hole in it. That's the good part. The bad side is the horrible smell! It doesn't seem to bother him, but it is horrible to my nose. It is so awful that I tried soaking it and dish soap and vinegar water overnight to see if I could make it go away. It was a little bit better but still stunk. Anybody got other suggestions on what could make the smell go away?

A good toy for chewers!!
Size: Large, Color: Blue
My dog loves this ball! The best part is that he hasn't destroyed it yet. He's a real chewer and has destroyed several toys since I got him about 6 months ago. The ball is very solid and a the squeak is not annoying. A great toy

My dog loves it, holds up well
Size: Large, Color: Blue
My German Shepherd absolutely loves this ball! He is a pretty aggressive chewer and it has held up really well, not indestructible but it lasts. We currently have three and he always has one in his mouth.

Lasted a year with a Great Dane
Size: Large, Color: Red, Size: Large, Color: Red
It lasted an entire year as my Great Dane’s favorite squeaky ball. The only reason it’s failing is because the squeaker no longer works great.
