4串磷酸铁锂电池组怎么给宏基笔记本供电。求成功方案。

输出那弄个点烟器接口，或者电池组做XT60,做个XT60转点烟器，插个65瓦以上的车充快充，用19V诱骗线给电脑供电。实测非常稳，而且车充快充日常在车上也用得着

联想有款电源带220转19v和12v升压到19V 通过转接头就可以

方法一，淘宝购买升降PD快充桌充，最起码支持65W，这样20V输出可以保证3.25A电流足够笔记本使用，如果笔记本支持PD充电那么可以直接使用，如果笔记本不支持PD充电，那么再买一个PD诱骗线方法二，淘宝直接买一个DCDC升降压模块，直接升压到19V接笔记本，不过普遍稳定可靠的DCDC升降模块淘宝很少见。基础思路基本都是要走升降压方案。

反正别走逆变电的弯路就可以

@"BG8AMG"#p23470 淘宝购买了DC升压板，又买了65W快充板，电脑依旧没有弄成功。考虑是电脑有点老了。朋友有苹果本，同样方法成功诱骗，，，改天用朋友本试试，如果可以就是我的本老了。方法，方向没有错。感谢出谋划策。

@"BI1IZF"#p23599 着两个方案都实施了。没有成功考虑两个问题，升压板不行，或者是本老了不支持快冲。感谢出谋划策。

@"BD3PZF"#p23791 补充一个，笔记本电脑大部分都是有信号识别针的，你先测试升压模块有没有输出，是不是正常的电压，如果升压没问题，那么你测试你的笔记本这边插头有没有电压，如果依然正常，那么就是识别针的问题，一般来说笔记本电源线里面都是三线的，也有两线的，识别针在插头里面，不在适配器里面

不能PD直接供电吗，pd多简单(

Please provide a power supply solution for a 19V computer using a lithium iron phosphate battery pack.

How can I power a 4-cell phosphate iron lithium battery pack for a Macro Base laptop? I need a successful solution.

BG8AMG

Output the interface for that cigarette lighter socket, or a battery pack with an XT60 connector. Create an XT60 to cigarette lighter adapter, and connect a fast charger (65W or higher) designed for cars. Use a 19V power cable to supply power to the computer. The setup is very stable, and the car charger can also be used regularly in the car.

BG8AMG I bought a DC power supply board on Taobao, and also purchased a 65W fast charging board. However, I still couldn't get my computer to work. I think the problem is that my computer is quite old. A friend of mine has an Apple MacBook, and he was able to do the same thing successfully. I will try using his MacBook another day to see if that works. If it does, then my computer must be the issue. The method and approach are correct. Thank you for your advice.

Lenovo has a power supply that converts 220V to 19V and 12V, stepping up to 19V. It can be used with an adapter.

Method 1: Purchase a PD fast-charging desk/table charger on Taobao, which at least supports 65W output. This will ensure that the 20V output provides sufficient current (3.25A) for your laptop to use. If your laptop supports PD charging, you can use it directly. If your laptop does not support PD charging, then purchase a separate PD adapter cable.

Method two involves purchasing a DC-DC step-up module directly from Taobao and then stepping up the voltage to 19V for connecting to a laptop. However, reliable and stable DC-DC step-up modules are rarely found on Taobao.

The basic approach for all of them involves using pressure regulation schemes.

BD3PZF

BI1IZF Both solutions were implemented. However, neither successfully addressed the two issues: the step-up transformer was not working, or the old system did not support fast charging. Thank you for your guidance.

Bi4KKF

In any case, avoid the detours of inverters.

BI1IZF

BD3PZF Additionally, most laptops have signal recognition pins. First, test whether the voltage booster module is outputting a normal voltage. If the voltage booster works correctly, then check if your laptop's connector has power. If it still works normally, then the problem lies with the recognition pin. Generally, laptop power cables are either three- or two-wire, and the recognition pin is located inside the connector, not in the adapter.

Can't PD directly provide power? Isn't PD so simple?
