各位友台，本人中意协谷的G90N，一直在选择移动电源，听说求精的品控不太行，请教各位有什么比较好的13.8V的移动电源🥰🥰🥰

我用的这个，单独买一根DC转安德森口的电源线[upl-image-preview uuid=786cf0c0-ca97-481d-8a78-f518389dd01d url=https://storage.hamcq.cn/2026-08-25/1787638426-311954-20260825141245-69-50.jpg alt={TEXT?}]

G90N就随便了，百瓦电台照样用一百来块的求精😄

4 串磷酸铁锂，大功率充电宝都可以带的动（需要诱骗线），发射时最大电功率也就 50W 左右

@"BA4JLD"#p102474 不骗你哈，大几万的设备照样连着一百块的求精😂 [upl-image-preview uuid=1faf243a-c6bd-40ef-92cb-0dcab585ba0f url=https://storage.hamcq.cn/2026-08-24/1787559822-65327-5817a8f2189a97312743bbb984a25f6c.jpg alt={TEXT?}]

@"BG7NOD"#p102477 Man！What can I say！

如果只是G90专用，可以看下明纬成品，LRS系列小体积电源，12V/6A足够，调整电位器能到14V左右，扣除线损，13.8V没问题，供参考[upl-image-preview uuid=51ef75fa-0b6e-472e-a836-6770acd78669 url=https://storage.hamcq.cn/2026-08-24/1787560808-51590-image.png alt={TEXT?}]

我用的明伟MSP-1000-15, 15V的医疗电源，微调最低能到13.2v，唯一的缺点就是风扇太大声，自己换了个猫头鹰风扇，直接就是无声高功率电源了，持续400w带载也不会过热。我是二手160元捡的，因为是医疗级的开关电源，干扰很低，求精什么的通讯电源实际上也是开关电源，真的要纯净的电源就是电池组或是纯线性电源，但是很重。

@"BU2GQ"#p102484 感谢友台😘😘😘

@"BU2GQ"#p102484 之前有个很好的通讯专用电源，给机关单位用的那种24小时开机的，超过10公斤重，大变压器，用的都是日本进口的蓝宝石红宝石的滤波电容，欧姆龙的继电器，带过压过流保护，还带备用电池充电功能，电压电流指示双表头，全新的，但是太大太重了，我100块卖了，你没听错，我一百块给朋友了。哈哈哈哈。（后来看了一下，咸鱼二手一般卖四五百左右吧）

Help with choosing a power supply for a shortwave radio.

BA4JLD

Dear fellow operators, I'm interested in the XieGu G90N and have been using portable power supplies. I heard that the quality control of Qingjing is not very good, so I would like to ask for your recommendations on a good 13.8V portable power supply.🥰🥰🥰

BG7NOD

As for the G90N, it doesn't matter; even a 100-watt radio can still be purchased for around 100 yuan.😄

BA4JLD

BG7NOD Thank you, fellow station.😃😃😃

4. The 4S phosphate iron lithium battery, along with a large power bank, can be used (requires a coaxing wire). When transmitting, the maximum power output is approximately 50W.

BA4JLD

BD3QCY Thank you, fellow station.😃😃😃

BG7NOD

BA4JLD I won't lie to you, even expensive equipment can be connected with a 100 yuan "Qing Jing" device.😂

BA4JLD

BG7NOD Wow! What can I even say?

BU2GQ

I used the Mingwei MSP-1000-15, a 15V medical power supply. The minimum voltage I could adjust was 13.2V. The only drawback was that the fan was very noisy. I replaced it with a silent, high-power fan, and now it's a completely silent and powerful power supply. It can continuously provide 400W with a load without overheating. I bought it used for 160 yuan because it's a medical-grade switch power supply with very low interference. For precision or communication applications, switch power supplies are also used. If you really need a clean power source, the best options are battery packs or pure linear power supplies, but they are quite heavy.

BA4JLD

BU2GQ Thank you, fellow station.😘😘😘

BG7NOD

BU2GQ I used to have a great power supply specifically for communication equipment, the kind used in government offices that could run 24 hours a day. It weighed over 10 kilograms, had a large transformer, and used imported Japanese blue and red sapphire filter capacitors, Omron relays, with over-voltage and over-current protection, as well as a backup battery charging function. It also had dual volt/amp meters. It was brand new, but it was too big and heavy, so I sold it for 100 yuan (approximately $15). You heard me right, I gave it to a friend for 100 yuan. Haha! (After checking Xianyu, similar products are usually sold for around 400-500 yuan.)

For G90 users, if it's specifically for G90, you can check out the finished LRS series ultra-thin, small-volume power supply, with a 12V/6A specification, which is sufficient. You can adjust the potentiometer to the maximum voltage, around 14V, and the official factory inspection report can be downloaded. Adding line loss to the radio end results in approximately 13.8V, so there's no need to worry too much about having exactly 13.8V; this is just for reference.

BA4JLD

BI1SFC Thank you, fellow station.🥰🥰🥰

BA7MGJ

I have been using Ming Wei power supplies from Taiwan, both 500-watt and 1500-watt models.

BG6XXW

我用的这个，单独买一根DC转安德森口的电源线

BA4JLD

BG6XXW Thank you, fellow station.😍😍😍

BI4PXL

If you want to save money, the easiest option is to use the server's existing 12V power supply. Buying a used one is also relatively inexpensive, costing around 100 yuan/RMB. Just find a reputable store; it's best not to buy any 12V-to-13.8V converter power supplies; instead, use the original 12V power supply.

BA4JLD

BI4PXL Thank you, fellow station.😃😃😃

BG6XXW

BA4JLD You can search further, as this one seems to have continuous power supply functionality, which is why it's more expensive. However, I haven't used this feature myself. These types of power supplies are typically used for square dancing speakers or electronic musical instruments like electric guitars. There should be cheaper options available too; you can search based on your budget. A stabilized power supply essentially ensures that the output voltage is within the device's input range, and it also supports the maximum current.

BG4QBF

The YSN batteries are actually quite good; I have two of them. For portable use, uninterrupted power is not a necessity, so you can find cheaper options without this feature. One battery, with approximately 150Wh capacity, allows me to operate my field station and provides up to 10A. The other, with less than 80Wh, can be taken on trains for use in different locations, providing up to 5A. They are both lithium iron phosphate batteries with a nominal voltage of 12.8V; even the G90S 15W unit can operate with small batteries (up to 5A).

看到电源进来，然后说要避雷求精结果楼主写明了我就安心了
