Tips
You can't see if the submarine has electricity.
When you get the submarine, you put it in the water. Its lights will turn on. Submarines must play in water.
It is charged very quickly. You can't see if it's charging or not. Charging is the same as usual. As long as it touches water, it will start normally. It's not broken, it just needs to start in water.

Q&A
Q: How do I charge?
A: You can use remote control or USB charging. If the remote control cannot be charged, it may be that the remote control battery is dead. You can charge with USB. But the usb must be connected to the computer to recharge. If the plug is directly connected to charge, it will burn out the built-in battery.
Q: Why the submarine is not bright?
A: You put it in the water at first. It will light up, and then you can operate it.
Q: Why the submarines work intermittently?
A: First you have to go full charge. Then control the distance not too far from it.
