充电的小台灯可以改装成直接插电使用吗，如何改
可以一边充电一边使用 不可以改直接插市电使用 如果改装成降压的 就没意义了 不如买一个。
可以改，增加降压、整流电路把家用交流220V变为台灯所需的直流低压就可以了。但如其他朋友所说，完全没有性价比，还需要你有相应的电子制作动手能力，不如买个现成交流220V输入全新的。
首先找个没用的手机充电器和数具线，把插手机那面插头剪掉，里面是四根线，用红色和黑色的两根。然后打开台灯盖，接电池上两根线，红对红，黑对黑，电池也不用取，接好就可以了。
1.可以将充电电容去掉，直接更换4700UF的电解电容。
2.充不进电的话你就把里面的电池线剪掉，电池就不要了，然后找个5V的充电器电流在1A(1000ma)左右。直接插在以前的充电孔应该就可以用了。
这样改装不合算的。首先充电台灯的灯泡和直接插电台灯的灯泡的电压等级和电源种类都不同，充电的台灯是直流小电压，直接插电台灯是交流大电压。

买个直接插电的台灯使用吧
怎样把手机改造成插电源可使用的电池电源两用机
手机怎样接带插头的导线可以插入插座，免充电使用？同时也可以充电池带出去使用，就象笔记本那样。为什么厂家不考虑使手机象家用电器一样可以插电源直接使用？电池只是外出时使用，才充电。手机总是要用电池天天充电，又要换电池很不方便。可以用，但对手机有害！
手机电池不但充当了储能（储存电能）的功能，同时还起到稳压、滤波等作用。当不装电池直接用充电电源供电时，由于失去电池稳压、滤波等作用，工作电压会比正常时偏高，来自交流电源侧的大量有害纹波，以及电源接通、断开时产生的瞬间过压，会直接作用在手机电路中，特别在供电电压不稳定的地区和雷雨季节时，极易造成手机的损坏。
综上可见，除非临时应急，否则不要在不装电池的情况下接入充电电源。

你手机配的充电器可以实现你想要的功能
给你出几个招，不过别嫌馊。因为你这个问题问的就有点馊。
第一，买个座充，能放手机的那种。在家的时候就把手机放在上面，永不断电，像无绳电话一样。
第二，自己动手改造。把手机后盖拆开，电池拿出，找个直流变压器，电压要合适（3.7伏，直流）。按照正负极把两根电线用电烙铁焊在电池触点上。
第三，把原装的线充插在手机上。
第四，装个固定电话。
第五，装个插手机卡的固定电话。
第六，干脆不用手机，不用天天充电又省钱。
第七，换个好点的手机，待机时间长的。
手机就是要用电池的，不用电池插电源的还是手机吗？那不就是电话了？

我一直是插着充电器躺床上上网的啊。

如何把装电池的玩具改成是插电源的呢，（在线等答案哦）
如何把装电池的玩具改成是插电源的，因为玩具是摆在店里摆饰的，要一整天都开着，所以用电池很浪费，所以想把它改成是插电的，请教各位高手教一下1.玩具使用两节5号电池它的电压是3伏
2.加一个220v变3v的变压器再加一个整流桥不一定可以,如果是电动玩具可以,如果是发声玩具或者电压要求稳定的玩具,就不能达到原来的效果,需要加稳压电路,
2.加一个220v变3v的变压器再加一个整流桥不一定可以,如果是电动玩具可以,如果是发声玩具或者电压要求稳定的玩具,就不能达到原来的效果,需要加稳压电路,
很简单，找个闲置的手机充电器（最好是300MA以上，以保能正常使用）剪断充电插头引线，红的接正极，黑的接负极就行了。
可以的，用220V/5V变压器加二只整流二极管，一只电解电容即可做成，可一整天都开着。

找一个线性适配器（手机充电器类，15~20块钱左右的成本，比较合适），或者开关电源（成本较高）或者普通镍氢充电电池的充电器（成本较高），最好标称输出电压为3V~4V左右，标称输出电流在0.4A~0.6A左右（这个要看玩具需求，但通常在0.4A左右），把接出口剥掉，万用表测试好正负极，接到电池盒上的正负极，用电工胶布包好即可。
这个方案应该是比较安全，也比较现成，供参考.

Magic away again - 98-84 eagles, 4-0 aggregate swept through. The magic of the 3-point 37 shots, nearly 16 in NBA playoff history record breaking.

8-0 before the playoffs, magic and other 5 teams together on history. Striker swarms of magic is undoubtedly become also three points, with three points, and regular magic 841 3-pointers NBA history records, when magic single-game a franchise-record 10 3-pointers or above (48), regular were up to 80% of their teams. But the playoffs, magic his opponent made 55 3-pointers, this is the big difference of 165 points!
Today, Michael playoff pietrus 3-point shooting, 41 cast 21 2007, Rashard lewis three points in 24, percentage of 52 46.1%, Jia mill Nielsen three points in 19 shooting, 47, Matt - three points and six Barnes, shooting 33.3 percent, J.J. - three points and five riddick, shooting 33.3 percent, Vince carter before 7 April 25 in three points, but today he sucked in July after 4 percentage promoted 25.6%. Although still not ideal shot, but don't forget to keep playoff record 3-pointer half the number is carter, 2002 in and air Philadelphia conference semifinals single-game hit eight points, so don't hit a veiled by carter.
Magic is so fierce, three points or Todd white Howard insider dominant part, and Howard surrounding hoarding, has also played a large release under the pressure of defensive role, it is no doubt that complement each other. Over the past three years lewis is career best 3-point percentage of time, but nelson over the past five seasons have 3 years 3-point all over 40%,There is a change NBA Jerseys destiny, riddick and Ryan Anderson such advantages and disadvantages are outstanding players also won plenty of space.
The magic, 1994-95 season with the Houston rockets. HaJiM - with hakeem olajuwon to the axis, when the rockets is top of good pitching center collocation. More than the magic of terrorist, when the rockets season has nine players in a 3-point percentage, Scott Brooks, Kenny Smith, Tracy Murray and Peter cher kete 4 people in 40%, Mario elie wiesel, Robert horry, Clyde drexler and Sam cassell - - it's completely unreasonable type. In the playoffs, they fire more terrorist,wholesale MLB jerseys, the rockets have six players 3-point in 4, Smith, Robert horry,NFL Jerseys, Clyde drexler, essien and Sam cassell 5 people into the 172 3-pointers!
Magic can repeat until the year towards the rockets? We wait and see!

我有一个小台灯，充电的那种。现在呢电池坏了，我想改为插头直接插到插座上用。应该怎么改的。需要什么配
我有一个小台灯，充电的那种。现在呢电池坏了，我想改为插头直接插到插座上用。应该怎么改的。需要什么配件？如果蓄电池是4V的那种电池，那可以将电池拆除，直接装一个USB接口的手机充电器使用。
多少伏的电池，多少A的？
本文标题: 请问这样的节日灯，可以把它们的电池改造成常见插电用的那种吗
