I want to buy a polishing machine to get rid of water stains. Generally, it can polish and also have waxing functions. Since the underground garage does not have a 220V socket, I can only buy lithium batteries. After looking around, I can divide them into two categories. One is relatively professional, and the price is generally over a thousand. The other is cheap, generally around 300, and the battery is around 12V2Ah. It claims to be able to work for 1.5 hours. In this way, the power is only 16W, which is still a waste. Wired ones are usually 1500W…
Later, I found a 20V battery. The power of this voltage should be okay, and the battery is 20V5Ah. If it can be used for an hour, the power will reach 100W (nominal 108W). I feel that it is enough for me. However, the size is really a bit big, and it seems that it cannot be operated with one hand. Although the price is less than 300, I still gave up.
Then I’d better go back to the 12V pile and choose. In fact, many brands have similar appearance, and the price is between 200 and 400. I took a fancy to one that claims to be produced by export standards. It is used for both lithium batteries and cigarette lighters. The cigarette lighter power cord is 2×1.5mm. It is indeed possible to use the material. The standard for 38 activities is 298 yuan. I want that cigarette lighter cord to be a single battery and a high-end. 360 yuan, order.
The experience after arriving is as follows:
1. The workmanship is passable.
2. Because it vibrates eccentrically, it will cause your hands to feel a little numb when it is used for a long time. If you turn around in a place like the hood, it will shake like the rumble of a plane flying past. In fact, this kind of low-speed machine feels that even if it is not eccentric, polishing will not damage the paint surface.
Wax is applied in gears 3 and 2 to 3, and wax is applied in gears 5 to 6. It takes about 30 minutes to complete the whole vehicle. It shows that three compartments are fully charged, no charging, and the battery is just used up.
4. The strength is okay. As long as it is not pressed with a particularly large force, it will not stop, but the speed will become much slower.
5. Waxing effect: It may not be as good as it is by hand, but the manual work is too tiring. Once you beat it in summer, the whole body is soaked and people will collapse. After using this, the time has not been greatly reduced, but the labor intensity has been greatly reduced.
6. Polishing effect: The speed is too low, there is almost no polishing effect, and the sun patterns are not thrown away at all. When combined with a reducing agent, I can wipe off the water stains that it cannot get rid of. I can wipe them off by rubbing them back and forth with a towel, which means the polishing effect is not as good as that of my hands.
Overall, although I didn’t achieve the purpose of buying it for polishing, waxing is still much easier, so I’ll keep it for waxing.
