How To Use A 5 Volt USB Source to Charge An HT Ham Radio

5V to 12V Cable: amzn.to/3OOiByp
I have a friend, I'll call him Tuje (pronounced Tooge). He has decades of experience in commercial VHF/UHF radio communications. He wants to share his knowledge, but he also wants to remain anonymous. I offered to host his videos on my channel. So here is another video in an ongoing series of helpful videos, primarily relating to VHF communications, but certainly not limited to that topic.

I'm going to add one of those cables to my kit. Great find!

[@RedSummitRF]

Me to. It will be handy to have.

[@MikeN2MAK]

Thanks, I need to grab one of these.

[@RedSummitRF]

Me too! lol

I always pack one of those 5V USB boost converters on my travels so I can charge HT's on the road.

[@RedSummitRF]

Thanks for mentioning that, Dennis. I trust your opinions. Sounds like it works great for you.

Besides these small USB buck and boost converter modules, there's another option now if you have a USB power block designed for type C rapid charging and power delivery. It's called a USB PD decoy trigger module. It can force the power block to deliver 5, 9, 12, 15 or 20 Volts, whichever you choose.

The person filming is mistaken. 5.12v*1.73A is about 8 watts. Accounting for losses in the system, you'd get around 6 watts out. At 12v, that's 0.5A.

Yeah, I think you are correct about that. It sounded like he was doing the math in his head on the fly.

thanks Charlie 73 dit dit

Thank you Brian!

I would like to suggest to "Red" that he understand and have proper knowledge of what he is suggesting people do. The device can overcharge a radios battery or battery pack and cause heating, catching fire, or even cause the battery to explode or burst into flames causing a serious fire!

[@RedSummitRF]

Hi Coy -Thanks for your comment, although you might consider re-watching the video. I don't think caught everything.

[@the1spyderryder]

Be careful using these, the battery in a Boufeng is a 7.2volt lion battery and should not be charged with a voltage more than about 8.2 volts. And the battery packs that have the coaxial female on the top of the battery pack, has no protection for the battery as far as over charge or anything else. I suggest using a USB DEVICE MADE FOR THE JOB like the baofeng USB CHARGER THAT IS MENT FOR THE JOB AND IS INEXPENSIVE!

[@RedSummitRF]

Coy - Generally I would say this is an accurate statement, but within the context of this video it's just not true.
