Is a razor with a built-in rechargeable battery? Is it better to use dry batteries?
1. Philips razor is good to charge. The durability of Philips rechargeable battery is similar to that of mobile phone battery, as long as the battery is not a very bad kind, basically do not have to consider. Three or four years later, it is estimated that your razor will have been replaced a long time ago. if you are more frugal, you can use the battery even if it is broken.
2. All the high-end Philips razors are rechargeable, and dry batteries only exist in low-end models. 2, battery problems can actually be ignored, now domestic small brands in 2: 30 can buy charging, the key is to look at the motor speed and blade grade, this is a direct difference.
3. The charging mode of power supply is different. The power supply type can only be used when the power is turned on, the battery type and dry power can be used by replacing the battery board, and the charging type can be used in the wireless state after being fully charged. Convenience is different. The power supply type should always have a power plug and cannot be used without a power supply.
4. The speed of the razor motor depends on the current supplied by the battery. The current of 4 volts is not necessarily smaller than that of 3 volts. Generally, the current of rechargeable batteries is larger than that of dry batteries. And do not have to change as often as dry batteries, and worry about dry battery leakage and so on. I suggest rechargeable.
In fact, everyone sees wisdom, although the battery type needs to change the dry battery, but Philips does a good job in saving electricity. It is absolutely no problem for two batteries to be used for two months, and it will be useful for half a year if there is more.
6. If the rechargeable battery is easy to replace, it is recommended to use the rechargeable series, the dry battery series are mostly low-end products, and the shaving effect is quite different from that of the rechargeable series.
Philips double-head razor charging, or battery good?
1. Philips razor is good to charge. The durability of Philips rechargeable battery is similar to that of mobile phone battery, as long as the battery is not a very bad kind, basically do not have to consider. Three or four years later, it is estimated that your razor will have been replaced a long time ago. if you are more frugal, you can use the battery even if it is broken.
2. There are also mid-range batteries that can be washed, of course, there are scratched prototypes, which may be discontinued, but they are cheaper (even at a 50% discount); the middle range is nothing more than washable, and there is a reciprocating sideburns knife. the high end is a mid-range + 3 knife head and a clearer display of electricity. But you can use battery-type domestic push scissors to cut sideburns.
3. Personally, I think Philips razor rechargeable and dry battery are good, mainly depends on your needs.
4. If you use it for your own use at home, you can buy a Philips rechargeable one. If you often need to go on a business trip and shave, of course, it is more convenient to use a dry battery. You can go to the Philips website to have a look at the specific model. Generally speaking, the Philips three-knife head is rechargeable.
Is it better to have a double cell or a single cell?
1. Compared with a single cell, it is safe to synchronize with high fast charging, because a single cell cannot accept high voltage and high current at the same time. The life of the so-called double cell is shorter than that of a single cell. I think unless it is high voltage and high current at the same time, it should not be a problem.
2. Single cell. The advantage of a single cell over a double cell is that it can be made thinner and the battery is more durable. The voltage of the dual-core battery pack is as high as 7V, so the divider chip is needed to power the mobile phone, and there is a loss of energy conversion during the step-down.
3. The advantage of "dual-cell" battery is that it breaks through the charging current limit of single-cell battery, and can charge two cells with higher current at the same time, which can double the charging efficiency. The disadvantage of the "double cell" battery is that the series connection of the two cells will cause the voltage to double and have a certain impact on the battery life.
4. Multi-core is better, because the multi-core wire is soft and not easy to break, which is convenient for later maintenance. The current transformers are installed in the cabinet, and the ammeters are installed on the cabinet door / instrument door, so this line must pass through the door. The wire passing through the door shall not use single core wire (because it is easy to break if the door is opened and closed frequently).
5. Double cells are good, fast charging, long life, double cells, single are virtual standards. 66w is not as good as 33w with double cells.
6. There is only a difference in capacity between single-cell battery and dual-cell battery (small single-cell capacity, large dual-cell capacity). In terms of battery life, single-cell battery and dual-cell battery life is basically the same. Strong endurance ability.
Is it better that the barber battery is integrated or can be separated?
1. High price titanium alloy + ceramic heat-resistant and durable, high price cleaning and maintenance general hair clipper adopts separate structure, the knife head is detachable to facilitate water cleaning after each use. It is recommended to drop a few drops of lubricating oil after cleaning to protect the knife head. Electric hair cutters are generally divided into battery type and plug-in type.
2. Each of the two kinds of rear axle has its own advantages. if the motor is broken, it must be the same model, if it is a separate modification, it is easier to change the size, or it is more convenient to change the small motor maintenance. However, the conjoined body has defects, once replaced, it needs the original factory parts.
3. The better brands of electric push shears are: Philips, Feike, Pentium, Wal, Panasonic, which are often used by hairstylists.
4. Personally, it is recommended to separate the front and rear ends, which is generally used when developing in a larger team. Now the more popular AngularJS and so on, the background can consider using MVC Web Api.
5, look at the power source, whether it can be charged and plugged in, if half of the shaved head is out of power, it will be too bad ~ the battery had better be charged with lithium battery to save time. Look at the noise, the international standard electric hair clipper type noise should be less than 75 decibels. Of course, the lower the better, it shows that the combination between the tool head and the motor bearing is good and the design is close.
6. If there is no cable, it is convenient to use, but the performance of the rechargeable battery will decline if it has been used for a long time, so the power will be reduced, the time will be shortened, and the rechargeable battery may be replaced if it is not well maintained. If it is not often used in places where there is no power outlet, it is better to have a cable.
Which is better, single cell or double cell?
Compared with a single cell, it can be safe and high fast charge synchronization, because a single cell can not accept high voltage and high current at the same time.

Single cell. The advantage of a single cell over a double cell is that it can be made thinner and the battery is more durable. The voltage of the dual-core battery pack is as high as 7V, so the divider chip is needed to power the mobile phone, and there is a loss of energy conversion during the step-down.
The double cell is good, the charging speed is fast and the life is long. The double cell and the single cell are all virtual standards. 66w is not as good as 33w with double cells.
The advantage of "double cell" battery is that it breaks through the charging current limit of single cell battery, and can charge two cells with higher current at the same time, so as to double the charging efficiency.

Advantages: the advantage of single-core wire is that it will be very convenient to thread, many electricians like to use single-core wire to lay circuits, and the stability of single-core wire will be better.
