USB-PD协议最大支持输出20V 5A，但是直接输出12V，受限于电流，最大功率是12V x 5A = 60W. 想要用满USB-PD协议支持的100W输出，再给电台供电，需要诱骗模块输出20V，再转12V或者13.8V。不过带一个适用新B合规的短波设备，直接输出12V应该足够了吧？另外，移动电源与USB-PD诱骗模块是否有可能带来新的干扰？有人测过某品牌的某款充电宝，纹波感人。找了一下站里的帖子，没人专门讨论过。有没有懂哥可以讲一下？

不考虑DIY，是怕做了个新东西吃灰。我觉得用电动自行车、电动摩托车电池供电是个好主意，特别是铅酸电池，接个线很容易。但是我滴两轮电驴是个锂电池的，电动车电池似乎有品牌自己的充放电协议，没仔细研究过。 ![以前帖子找到的图](https://storage.hamcq.cn/2024-08-21/1724222390-404409-58b2efbd6258cc621dd8914ec9f5e34.png) 图片来自这个帖子： https://forum.hamcq.cn/d/2575/18

干扰问题可以实际接电台测试，不要看别人，动手去测，升压带来的是效率和发热，电台用电特点基本就是待机和瞬间大电流的工况，充电宝能不能抗住这种冲击这是个未知，另外还要考虑射频功耗和实际电源功耗的情况，稳妥是用电池

@"Ironic"#p100046 拿万用表看看电瓶车充电口有电压输出没，有的话，直接买电压匹配的转12V的转换器就行了。

充电宝给705或者g90供电就差不多了，再大功率的别想了

应该出不来特别大的功率，不过我用来给g90供电是绰绰有余了，今年我就用酷态科充电宝+诱骗线打的木兰围场

个人看不出来有什么干扰，往电源线上加了个磁环也不知道有没有用，哈哈。

@"BI1SFC"#p100047 发帖问，主要是问试过的人有没有实践经验，少踩坑，少做无用功。

@"BG5JKZ"#p100060 我估计的情况差不多，只能带动新B合规的短波设备

我当年用6100+12v诱骗打的cqww，插上可能会有点干扰，还有留意电流避免损坏机器今年我用705+12v诱骗参与的iota，感觉就那样

6100建议用9V诱骗，发热会好很多

What should be considered when using a power bank + USB-PD module to output 12V voltage to power wireless devices?

Ironic

The USB-PD protocol supports a maximum output of 20V 5A, but directly outputting 12V is limited by the current, resulting in a maximum power of 12V x 5A = 60W. To achieve the full 100W supported by the USB-PD protocol, while also powering a radio, it would require tricking the module into outputting 20V and then converting it to 12V or 13.8V. However, if you have a shortwave device that is compliant with the new B standard, directly outputting 12V should be sufficient, right?

Additionally, could portable power banks and USB-PD deception modules potentially introduce new interference? I recently tested a specific brand of power bank, and the results were quite concerning. After searching through forum posts, I couldn't find any discussions specifically about this issue. Could someone with expertise shed some light on this?

Ironic

I'm not considering DIY because I'm worried about making something new and having it malfunction. I think using a battery from an electric bicycle or scooter is a good idea, especially lead-acid batteries, which are easy to connect. However, my two-wheeled electric vehicle uses a lithium battery, and I haven't thoroughly researched the charging and discharging protocols specific to certain brands of electric car batteries.

Ironic Use a multimeter to check if the e-bike charging port has voltage output. If it does, simply purchase a converter that matches the voltage and converts it to 12V.

The interference issue can be tested practically with a radio, don't just look at others, try it yourself. Increasing the voltage brings efficiency and heat generation. The typical power consumption of a radio is mainly standby mode and sudden high-current operation. Whether a power bank can withstand this impact is unknown. Additionally, you need to consider the RF power consumption and actual power consumption. It's safer to use a battery.

Ironic

BI1SFC I'm posting a question to see if anyone who has tried it before has any practical experience, so that I can avoid making mistakes and wasting time.

BG5JKZ

A power bank should be sufficient to charge a 705 or G90; don't bother with anything more powerful.

Ironic

BG5JKZ My estimate is similar; I can only support new B-compliant shortwave equipment.

BG2FZJ

It shouldn't produce particularly high power, but it's more than enough for powering the G90. This year, I used a CoolTech power bank and a "lure" cable to charge in the Mulang field.

BG2FZJ

I couldn't see any interference myself. I added a magnetic ring to the power cable, but I don't know if it helped or not. Haha.

BG5GDP

I used a 6100 + 12V to lure CQWW, but be aware that it might cause some interference. Also, pay attention to the current to avoid damaging the equipment.
This year, I used the 705 + 12V to lure in participants, and it felt like a complete failure.

BG2KAJ

6100 recommends using a 9V battery to induce heat, which should significantly improve the situation.

BH3NEK

I bought a bait but haven't tried it yet. I'm going to try using it on my X6100 next.
