【贴图】OPPO/一加/华为 三款5A大电流快充数据线拆解与评测
本帖最后由 camio 于 2016-12-3 22:39 编辑实现手机快速充电说到底还是要对手机电池大功率充电，从充电器输出这一端来说，OPPO的VOOC方式是低电压大电流，高通的QC2.0和QC3.0是高电压低电流。谷歌对高通的快充QuickCharge方式不感冒，亲儿子手机没有采用高通快充方式。
记得较早时候，比如摩托罗拉手机充电器，输出4.2V，等于直接到电池端，电池内部没有降压的损耗和产热，电能传输直接简单。当然现在的手机电池很多都是高电压电池也支持高倍率充电，比如4.35V和4.4V的电池，充电器直接输出4.4V到手机内部这种传输方式类似早期摩托罗拉手机那种输出方式。低电压要想实现大功率充电，自然电流要很大，对充电数据线的承载能力要求很高。假如充电功率20W，电压4.4V，那么对数据线电流通过能力的要求接近5A了。
今天要比较的就是三大电流通过能力达到5A的数据线：OPPO的VOOC闪充数据线、一加的DASH闪充数据线和华为的SuperCharge超级快充数据线，前两者同属一派，不过VOOC闪充数据线是USB-A to MicroUSB（特制），而后两者是USB-A to C。
一、外观三种线材外观对比http://cms-bucket.nosdn.127.net/catchpic/6/60/6019484a4d8e687d18ef5eda10051942.jpg?imageView&thumbnail=550x0从左至右依次为DASH闪充线、VOOC闪充数据线、华为5A数据线。
http://cms-bucket.nosdn.127.net/catchpic/2/2d/2df323d9c117f0cbf8d10c60c8b5340c.jpg?imageView&thumbnail=550x0三种线材的收束方式不同，DASH线和VOOC线有专门的束线卡扣，华为5A线显得随意一些，只用了一个塑料套套住。
http://cms-bucket.nosdn.127.net/catchpic/3/3f/3f8d8d7c09bc8f656fe9a47e1700e9d3.jpg?imageView&thumbnail=550x0三条线的粗细看起来差不多。
http://cms-bucket.nosdn.127.net/catchpic/2/28/28132eafb4b1229e3443ef5e8b63fb46.jpg?imageView&thumbnail=550x0三条数据线的端口放在一起对比。http://cms-bucket.nosdn.127.net/catchpic/4/49/49d0a3033de4c284bf65b47763acc62d.jpg?imageView&thumbnail=550x0VOOC闪充线使用的是特制的MicroUSB端口，与普通MicroUSB数据线看起来不同。华为5A数据线、DASH闪充数据线两头看起来与普通Type-C数据线无异。
http://cms-bucket.nosdn.127.net/catchpic/e/ef/ef8de7757d6402724bbaec48660c26f5.jpg?imageView&thumbnail=550x0每条数据线的舌片颜色不同。
http://cms-bucket.nosdn.127.net/catchpic/2/2d/2d7e0c55481d11c0280a21fc16adaae2.jpg?imageView&thumbnail=550x0从上到下依次为紫色舌片的华为5A线、绿色舌片的VOOC闪充线、红色舌片的DASH闪充线。
http://cms-bucket.nosdn.127.net/catchpic/e/ec/ec59129585f27499e9d8a240e710f178.jpg?imageView&thumbnail=550x0USB公头和Type-C公头颜色一致，一一对应。
http://cms-bucket.nosdn.127.net/catchpic/9/93/93cb4cd4a6f00a551e4ec59fec8b54b5.jpg?imageView&thumbnail=550x0三条数据线USB公头对比。
http://cms-bucket.nosdn.127.net/catchpic/0/06/06fbe0a888b6149516f842aed0df16ea.jpg?imageView&thumbnail=550x0另一端的公头同样使用了不同颜色的胶芯。
二、测试测量一下各自的带皮线径粗细。http://cms-bucket.nosdn.127.net/catchpic/4/4d/4d904a1be5c69ea406e19552df0b3bfc.jpg?imageView&thumbnail=550x0首先是华为5A线，千分尺显示为3.86mm。
http://cms-bucket.nosdn.127.net/catchpic/5/51/510a7c8501fabca20b43c7933cbf342d.jpg?imageView&thumbnail=550x0VOOC闪充线，测得直径为3.89mm。
http://cms-bucket.nosdn.127.net/catchpic/b/b3/b39a714185399cdb99b449cd03995a2c.jpg?imageView&thumbnail=550x0DASH闪充线，测的直径为3.87mm。忽略夹紧力度与线材粗细不均，三者的粗细基本接近。
http://cms-bucket.nosdn.127.net/catchpic/a/a3/a347fafccdfb8412ee46b89b32e5e690.jpg?imageView&thumbnail=550x0大致测量了一下华为5A线和VOOC闪充线的长度，均在1m左右。
http://cms-bucket.nosdn.127.net/catchpic/8/81/8175fdac2da11fc79b8e0e91a65bd4a2.jpg?imageView&thumbnail=550x0DASH线微微超出1m。接下来通过固定输入端电压、增大电流的方式测量数据下两端的压降间接求得线阻。实验采用POWER PARTNERS的QC电源，少有的可以5V4A输出的电源，QC可以20V输出也是绝无仅有的。先是VOOC闪充线。http://cms-bucket.nosdn.127.net/catchpic/b/b7/b77c97b93620b05396f2dd61d97409e5.jpg?imageView&thumbnail=550x0未通电流时，空载电压为5.0345V。http://cms-bucket.nosdn.127.net/catchpic/2/28/28182edcb142bdeb64101f77c33aeb98.jpg?imageView&thumbnail=550x0通1A电流时，电压为4.8831V。4.7142Vhttp://cms-bucket.nosdn.127.net/catchpic/9/96/96339641e231024b17d768c150c3f4aa.jpg?imageView&thumbnail=550x0通2A电流时，电压为4.7142V。http://cms-bucket.nosdn.127.net/catchpic/a/ae/aecef26f506974c1fc510ae7b7d7cc72.jpg?imageView&thumbnail=550x0通3A电流时，电压为4.5694V。http://cms-bucket.nosdn.127.net/catchpic/f/f0/f07a9b07761a0200752a07c14b999670.jpg?imageView&thumbnail=550x0其次是DASH闪充线。http://cms-bucket.nosdn.127.net/catchpic/9/97/97fcaaea10a08278e84bc94de666aab7.jpg?imageView&thumbnail=550x0通1A电流时，电压为4.888V。http://cms-bucket.nosdn.127.net/catchpic/0/03/037e0e82ccd8bdd6d217f1616d53412c.jpg?imageView&thumbnail=550x0通2A电流时，电压为4.740V。http://cms-bucket.nosdn.127.net/catchpic/b/b1/b1a9ae1e51ffc6904a5df19f104f6546.jpg?imageView&thumbnail=550x0通3A电流时，电压为4.600V。http://cms-bucket.nosdn.127.net/catchpic/c/c1/c150c4830a19a09c66bef2bb93478ba2.jpg?imageView&thumbnail=550x0通4A电流时，电压为4.453V。最后是华为5A线。http://cms-bucket.nosdn.127.net/catchpic/0/07/07247b6a8d58802d6c47d00baac2e1c5.jpg?imageView&thumbnail=550x0未通电流时，电压为5.035V。http://cms-bucket.nosdn.127.net/catchpic/8/81/81e6f178da25c263a3f439eb2f4d6735.jpg?imageView&thumbnail=550x0通1A电流时，电压为4.893V。http://cms-bucket.nosdn.127.net/catchpic/b/b5/b574dac6644a822cfd49c0427bcf2838.jpg?imageView&thumbnail=550x0通2A电流时，电压为4.741V。http://cms-bucket.nosdn.127.net/catchpic/a/a7/a729d29f483d8dfd761d1fee0eba9176.jpg?imageView&thumbnail=550x0通3A电流时，电压为4.603V。http://cms-bucket.nosdn.127.net/catchpic/7/75/75b31a172a6d392a66b07178a2137d24.jpg?imageView&thumbnail=550x0通4A电流时，电压为4.463V。数据汇总如下：http://cms-bucket.nosdn.127.net/catchpic/f/f8/f84ef10623c2bf9275e34b7307626c5c.jpg?imageView&thumbnail=550x0%ef%bd%8f900可以得知三条线的差异很小，华为SuperCharge 5A线稍稍胜出一筹。

总结：三款线用料十足，结构上有共通的地方：用了两条红线作为通过5A大电流；同样宽厚的V+V-，相当于双倍的一般的公头的宽度；用了缠绕方式作为屏蔽层，保证了线材粗而软，不至于过硬。其中VOOC闪充线和DASH线多了一个针脚用于识别。
^g^真有空闲。。 ：不知道过电的那两条线有1.0的线径吗？不知道搞个rvvp4*1.0或1.5的短线试试效果 其实就2种线，华为是一家，另外两家是一家（一个规格，一样的设计。）
华为无芯片，应该是其快充标准由手机端独立完成，对线的要求仅仅通过电阻识别是否为自己的线而非兼容线从而开启快充模式。
另外两家的快充设计是由线（有芯片）和手机端共同完成。
做工都很好， 写这么长应该不是5毛的稿费吧 看来只要是正品质量都不错~~~ 看来oppo与一加三可以通用 看来线径还是不小
