The Power Adapter Is Made Of Two Parts

Under the premise of guaranteeing quality, we naturally hope that the more light

the better the power adapter, through the above analysis, we can see some of the notebook adapter, Lenovo has successfully "downsizing", not only reduces the size lot, but also reduced the weight 0.24 kg or so.

Acer's new notebook a high degree of recent attention, in addition to cost-effective, the more light than other books of the body is one of the reasons, but if together with the adapter into the bag with the words, their total weight does not light than other books . It appears that Acer may be able to consider redesigning the look of its power adapter.

Different output current universal adapter you can

As we all know, the power adapter is made of two parts, one side is the power adapter, on the other side is the power cord and plug the access hole notebook, part of a power adapter failure, sometimes we just replace that part of the can be met, then not-for-hole here, this is to use other adapter, of course, buying a new can. So the question now is, the same nominal power supply voltage, output current, if different, can be used in the same notebook? The underlying principle is: The nominal current of the power can replace the small nominal current of the power supply.

Some friends have misunderstood, that a large nominal current of the power supply will burn books, because the current big thing in. In fact, what the current situation in the same voltage depends on the load, that is, the work books, when the books when the high-load operation, the current bigger, books go into standby when the current on the smaller, short current equal increase in books on the equivalent resistance voltage divided by the books. Nominal current of the power supply large enough current margin, not in place after a small nominal current of the power of overheating or low output voltage conditions.

On the contrary, instead of using a small current-current power supply, there exists the danger. But some friends with 56W instead of 72W of power have no problem with them, because the power adapter is usually designed to leave a margin, load power must be smaller than the power, so this place is in general use feasible, but the margin on the remaining power supply is very small.
