These are solid little power supplies. I have a nearly identical unit from R&L that has served me well. One thing to note is you will see these units with either a 12V cigarette lighter socket or 2 sets of power poles on the front panel. My R&L unit has the power poles which come in very handy in the shack.
One thing to keep of note is that the front ports (be it powerpoles or a "cigarette lighter" jack) are typically lower amperage, so you wouldn't want to power a base station rig, or cigarette lighter for that matter, via the front. I was looking into voltage adjustable desktop power supplies for electronics projects that also put out 30+amps to use with a radio(s) for eliminating clutter in my shack/electronics bench setup. Many of the more affordable ones don't have the offset function, and are not designed for rag chewing. It would be cool to run one power supply though... If anybody is running a setup such as I described, I'd be interested to know what supply you went with, and if you have noticed any noise issues, both RFI and fan noise. It's probably best just to use two anyway, just incase I had the voltage set higher than 13.8, and powered on my rig, then again, circuit protection devices should prevent any damage. idk. was just a thought.
@@jampskan5690 I have an Alinco with cigarette lighter socket option. Never used it. Curious as to know how are they to be used or how have you used it ?
~$25 eBay ex-server e.g. HP HSTNS-PD18 750 watt (12V/62A!!!) power supply can be modified with one resistor to tweak output to 13.5V. RF quiet, being HP ex-server = super high quality. Far more amps capability than dollars cost. An option for those able.
I've heard of people using these. We built some at the ham radio clubhouse one day. I had too many power supplies (and still do) to put the server PS into service. Glad it is working well for you!
When i got my first hf radio in 2015 as a high schooler, that was the exact power supply i bought. Its still my only power supply i use for my QRO radios.
I got one of these based on your review (thank you). I've had it for a week now, and it's been great so far! It's a nice addition for me because I needed the "lighter" socket so I can power a battery eliminator for handhelds while they're in the "shack". Also, I'm setting up a new ID-5100A and it's doing the job very nicely.
My Icom power supplies were to heavy to take to Sth Korea, so I'm using the same one as your showing and it's been working a treat with a FT-891 doing continuous FT8 @ 30 watts for hours and hours and hours., and the lighter socket with fast USB charging for power to tablet and phone.

I've always had the astron rs-35a and it is always a challenge finding a good spot for it. I don't think I'll be replacing it anytime soon, but it's good to know what else is out there. I also did not realize that some switching power supplies give you the option of moving the noise offset, that's awesome!
@@temporarilyoffline Right, exactly. Knowing that it exists gives me that knowledge in case someone throws out something about switching PSU's being too noisy, etc 👍 "The more you know" 🤣
I have one that looks identical, has the same model number but sold under brand name Norjin. It does have noise. The worst of it is on 20m. The noise knob does move it out of the way. The only annoyance is that these bands of noise drift until the power supply warms up fully. Once it warms up the noise bands stop moving. I'm just powering a Hermes Lite 2 so more than adequate. I've never once heard the fan kick in.
@@temporarilyoffline Not until now. I have continuity from 13.8V ground connector to long pin on AC connector which I assumed is what you were testing on. I also have continuity from that pin to 13.8V positive connector, so I don't know what that means. I noticed the PS does actually have QJE stenciled on the front so it is identical to yours. The measured voltage on mine is 13.68V. The noise is manageable with the knob so for the price not complaining. I got it off Amazon scratch and dent section for the equivalent of about $60 USD.
I have the same power supply but with an lcd meter. Got it for 10 bucks at a swap meet. I took a chance as the guy had no idea if it worked. It's been powering my ic7300 for the last 9 months without a problem!
Excellent current draw at idle on the 705. Impressive! My old IC-706 rests at 1.5A in RX mode! NG. It also gets very warm from the voltage regulators inside. The 705 and the additional external amplifer makes a GREAT combo. Power when you need it, and effeciency at the same time. 👍
Picked this up on your recommendation and have never been happier with a power supply. Mine too has zero noise, so I haven't been able to use the noise offset, but that's a good thing, right!?! Price was perfect and this has such a small footprint that I can put it anywhere on my desk. Very nice, thank you for the tip.
Mine went bang recently, a very loud bang, whilst I was semi-snoozing half listening to a dx station, made me jump. Don't know what component has blown yet, but thankfully no radio equipment damaged, so must just cut straight off and not output any over voltage.. that's a plus. Using a Nevada PS-30M linear PSU now, which is actually a similar price to that little QJE.. has a stupid loud fan on it though which is going to have to have to be modded soon.
Really glad to have found this video. It speaks to tightwads like myself who struggle to move forward when presented with the immense cost of HAM gear that people most often display in their shacks, especially on YT. This little QJE is now on my amazon list, thanks!
I'm pretty cheap too! After a while you just start to accumulate and trade stuff around and somehow it all multiples. Just wait, before long you'll be scratching your head not having any room!
Love the switching power supplys. I have 2 Samluex, a 35 amp and a 23 amp. Both have lasted more than 5 years. Nothing wrong with Ashtrons, you just need 2 men and a small boy to move them. 73
I have the "TEKPOWER TP30SWI", a cousin to yours. I think the common ancestor is the Alinco switching PS. If you look at your waterfall and twist the noise offset, you should be able to find the "noise".
Excellent Matt! In my case the noise wasn't on any band that I looked at, so must have been out of range of my antenna or otherwise irrelevant. It's a great little workhorse.
Great video! I have a QJE PS30SWIII (it's older, even though it has more "i"s in the model) Rated to 20A continuous. My only gripe (if you can call it one) is that I would prefer that it had Powerpole connectors. And, since It's on my bench, I would prefer that it had front connectors. But I digress. Anyhow, I was wondering, does the fan stay on, or is it triggered by a thermal switch? 73
I have two very similar TP30SWI 30Amp / 13.8V power supplies sold under the Tek-Power brand and like em both a lot. Here's a nice 50 Amp variable power supply I purchased on Amazon. (9-15 volts adjustable). Very quiet. It's called the Jesverty SPS-50II
I have exactly this one in my shack and it is a really compact, lightweight and reliable power supply. Also the noise offset button comes pretty handy. But it will not provide enough power for two 100 Watt transceivers in parallel. Even with my IC-7300 alone there is a significant voltage drop to 12.2 Volts when transmitting at full power.
I have two of those Power supplies. Very quiet and work great. Mine tests at 13.9v with a voltmeter. I have never heard noise from either of my power supplies. My fan has never came on.
@@temporarilyoffline LOL. I am 100% happy with mine. I have a 50 amp Pyramid power supply. It is terrible so much noise I cant use it with my radios. These 30 amp ones zero noise.
@@temporarilyoffline I’m new to HF, and I’m getting a mint 991a from my nephew. Per the specs it looks like it can draw 23A. Just curious if anyone has anyone has used this setup. Thx for the reply!
I just got one of these today for my tyt 9800. Thanks for the video! What size O-lugs would you recommend for standard fused red/black car stereo power cables?
I'm going to take a guess that they are 12ga wire and I'd say to use the yellow ones. Usually you can get a cheap crimper and it comes with reds, blues, yellows.
I have a huge Astron, and it turned out not to put out enough power for 100W radios, it runs mobile units just fine. So - The country we don't mention came to the rescue.
One of the problems I have with that power supply is that it is fixed at 13.8V. Years ago, when I got my Jetstream JTPS31MB 30 amp switching power supply, which was being discontinued when I got it, it had an adjustable output. It had a detent at 13.8V, but could be turned up a little higher. When it was new, it actually put out 13.8V when it was set on 13.8V. But over time the output slowly dropped. Now, to get 13.8V out of it, I have to turn it up a bit beyond that. I also now wish I had gotten a 50 amp power supply, and will be getting one in the near future.
Good video. I got a Alinco MV-330 35A max 30A continuous for my PSU in the shack when I got my first G90 last May. $189 I think, from HRO with free shipping.
Great vid. The psu is the same as my Maas sps-250 ii I just Changed the fan out With a noctua NF-A6x25 The fan is totally silent with the low noise adapter, and it fits strait in, you just need to Change the plug. Same as the ic 7300 fan mod/upgrade. Works fantastic 73 OZ7KP
This thing powered my first non handheld radio a bit ago. I was immediately happy and realized this DEFINITELY isn’t my last radio nor power supply 😅 my eyes are already set on one of those pricey yaesu radios… definitely gonna save and think it over for a good while. I’ve got too much antenna projects on the board.
@@temporarilyoffline I was a little turned off at first not gonna lie, it seemed so complex yet boring. Finally got out of the headspace where I “have to catch on immediately” im already thinking of putting a radio “permanently” on my car haha
wait im confused. you can use the xpa125b with this? The XPA125b outputs max is 30 amps so with an added transceiver wouldn't this power supply be pushing it or not have enough?
The manual specs "30A @ MAX", as you saw in the video, I wasn't "@ MAX" and everything was happy. This will vary from band to band, and I don't know which band would put it "> MAX", but it will just shut down as it runs out of juice - like I mentioned in the end of the video. Thanks for watching!
@@1234abcfgsbsb Take a look in the beginning of the video where I show "key-down CW" into the amp and it handles it just fine. THis is on 20m, but it (might not work) on say 80m. Its a good starter power supply, you'll know when you need to get a bigger power supply.
You didn’t mention that when most switching supplies fail they will send 120 volts AC into whatever they are plugged into.Also most need a couple of Snap On Ferrites on the power cord or they send a constant birdie on different frequencies across the Amateur Bands.I have the same power supply with a different name and it’s the TEKPOWER TPSW30SW1.Lots of other companies have their names on them including R&L Electronics.They don’t have the noisy fans like the MFJ switching supplies that the fan runs all of the time & that’s a Plus.They work great as long as there is no failure and if so your gear will be Forever Toasted.Also the noise mine puts out is not affected by the knob at all.👍🎙
Hasn't happened to me, but it's a risk with all power supplies. My Kenwood brand power supply blew a regulator and sent >20v downstream. Luckily I was testing it before connecting any gear to it and a simple part replacement got her back in shape. Fuses and crowbar circuits! Even then you're still just crossing fingers
I'm looking to grab a Retrevis RT95 / Anytone AT-778UV, it looks like it has a T connector, say I bought this power supply, are there cables out there that I can buy with a t connector on one and, and the ring loops to attach to the power supply? I'm a complete newb here and am out of my depth. With the ring attachments, does the back covers on those terminals screw off then you install them and tighten them?
Usually the posts on the power supply will screw off and you can put these on. You have a 99% chance of making it work out of the box. If they don't fit, you have 2 options: 1. Cut them off and strip back the wire and wrap it around the posts or 2. Crimp on your choice of a better end. Welcome to the hobby!
Nice review mate. I'm using the same power supply whilst travelling around Asia for the past 5 months hooked up to a FT-891 @ 20 watts, all good and fine until 3 weeks ago. Switching it on, it turned off and won't start. Checked fuse, used a different socket and cable and looked for anything obvious to the eye under the bonnett. The FT-891 works fine on battery and has been doing a great job at 20 watts from the apartments and rooftops in Thailand, Vietnam and Sth Korea :) You mention protection curcuitry, is that resetable ? The FT-891 at 20 watts is the only device that has been attacked. Any suggestions? VK4 FOO is here in Daejeon ROK - Stephen
Would anyone know about over voltage protection on these QJE power supplies? I got the QJE PS30SW IV (the digital display one). It works great, but I am always worried that if anything goes wrong inside the power supply, it could exceed the max voltage output and burn my radios. I am even considering putting together a crowbar circuit, but I would prefer to avoid the additional clutter in case the PSU has it onboard.
I don't know if the PSU has protection from itself, but I do know that it will shutdown if there is an over-voltage on its power ports - I had an amp fail and dead short. PS saved the day!
I have a 6W Yaesu FT-818ND and a complete newbie so I don’t have a dedicated external power supply for it yet… is this power supply going to be ok if the 818 is the only load or will it be too hot for it..?
@@temporarilyoffline Excellent, yes I've ordered one. I was shopping around awhile and whilst a couple available locally are a bit cheaper they don't have some of the protection features.
BUT....how long will the switching supply last? if switching supplies were quieter and lasted as long as a good linear, i would buy one in a heartbeat. the astron 35a linear supplies will last 20+ years with nearly continuous use. i don't think there is a switching supply out there that will last more than a couple years of continuous use, if that. so, in the long run, linear is $100 to $150 more expensive, but will last maybe 5x's or more than a switching supply. so, it is a no-brainer to go linear. portability would be the only reason i would use a switching supply. i'd get a good one like the one you have here, but it would not be a continuous use supply. field work, POTA, SOTA...stuff like that only. the total cost of ownership of a good linear unit is actually cheaper than a $97 switching supply. just my two cents. 73.
Cause doesn't make noise it doesn't mean radio is happy, put an occiloscope and you will see all the a/c ripple that will scare you. Up to 1 a/c volt peak to peak on 40m, yes the frequency changes the ripple.
I will stick with astron . More exoensive but so far never had an issue. , or yaesu fp-1030. Astron makes small switching ps's. But fir rf work i prefer linear over switching but thats purely a preference. If that ps works for you , stick with it. WA4UJY
There's nothing like good linear power supply. I know they are heavy, girls. You're just going to have to man up if you want quality, clean ( I'll say cleaner ) power. All power supplies are going to have some ripple. It's the nature of the beast. Also stop buying that Chinese junk that's poorly designed and made from low quality parts. Build a power supply yourself.

The manual specs "30A @ MAX", as you saw in the video, I wasn't "@ MAX" and everything was happy. This will vary from band to band, and I don't know which band would put it "> MAX", but it will just shut down as it runs out of juice - like I mentioned in the end of the video. Thanks for watching!
@temporarilyoffline so if you were to use the amp at its max then that power supply would not be sufficient?
@@1234abcfgsbsb Take a look in the beginning of the video where I show "key-down CW" into the amp and it handles it just fine. THis is on 20m, but it (might not work) on say 80m. Its a good starter power supply, you'll know when you need to get a bigger power supply.
It looks great for your RV, not too big and heavy. The only issue is you keep buying more equipment.😂
This one is already sold! I'm going to run on battery/12v RV system going forward
*30 Amp - bubba, 30 watts ain't gonna do the job. By the power of GraySkull!
another one of those...
Solid review, and appreciated.
Glad you enjoyed it!
You didn’t mention that when most switching supplies fail they will send 120 volts AC into whatever they are plugged into.Also most need a couple of Snap On Ferrites on the power cord or they send a constant birdie on different frequencies across the Amateur Bands.I have the same power supply with a different name and it’s the TEKPOWER TPSW30SW1.Lots of other companies have their names on them including R&L Electronics.They don’t have the noisy fans like the MFJ switching supplies that the fan runs all of the time & that’s a Plus.They work great as long as there is no failure and if so your gear will be Forever Toasted.Also the noise mine puts out is not affected by the knob at all.👍🎙
Hasn't happened to me, but it's a risk with all power supplies. My Kenwood brand power supply blew a regulator and sent >20v downstream. Luckily I was testing it before connecting any gear to it and a simple part replacement got her back in shape. Fuses and crowbar circuits! Even then you're still just crossing fingers
I'm looking to grab a Retrevis RT95 / Anytone AT-778UV, it looks like it has a T connector, say I bought this power supply, are there cables out there that I can buy with a t connector on one and, and the ring loops to attach to the power supply? I'm a complete newb here and am out of my depth. With the ring attachments, does the back covers on those terminals screw off then you install them and tighten them?
Usually the posts on the power supply will screw off and you can put these on. You have a 99% chance of making it work out of the box. If they don't fit, you have 2 options: 1. Cut them off and strip back the wire and wrap it around the posts or 2. Crimp on your choice of a better end. Welcome to the hobby!
@@temporarilyoffline Thank you for the reply, good to know!
@@MrBikboi ubet
What type of noise? Is it detectable in recieve/transmit? Or is it just audible to your ears?
For those that get it, it is RFI that shows up in the waterfall. I haven't personally seen it.
Does your fan run continuously when you turn the power on? My fan has never turned on even under a 10 Amp load.
I sold this power supply a few years ago, so I don't remember. How hot does your PS get on 10a load? Maybe not hot enough to key the fan?
Nice review mate. I'm using the same power supply whilst travelling around Asia for the past 5 months hooked up to a FT-891 @ 20 watts, all good and fine until 3 weeks ago. Switching it on, it turned off and won't start. Checked fuse, used a different socket and cable and looked for anything obvious to the eye under the bonnett. The FT-891 works fine on battery and has been doing a great job at 20 watts from the apartments and rooftops in Thailand, Vietnam and Sth Korea :) You mention protection curcuitry, is that resetable ? The FT-891 at 20 watts is the only device that has been attacked. Any suggestions? VK4 FOO is here in Daejeon ROK - Stephen
Mine auto-reset after I removed the problem and cycled power. No power out at all? Might be time for repairs.
New person question. Can you use 1 power supply to power more than one radio at a time? Or is it safe to do that? Or is it one power supply per radio?
You can power two radios from the same supply, but you can TX on both at the same time. Not enough amps for both
Would anyone know about over voltage protection on these QJE power supplies? I got the QJE PS30SW IV (the digital display one). It works great, but I am always worried that if anything goes wrong inside the power supply, it could exceed the max voltage output and burn my radios. I am even considering putting together a crowbar circuit, but I would prefer to avoid the additional clutter in case the PSU has it onboard.
I don't know if the PSU has protection from itself, but I do know that it will shutdown if there is an over-voltage on its power ports - I had an amp fail and dead short. PS saved the day!
See comment from Neal below about his going Bang!
I have two of the exact same PS - But branded as R&L Electronics. Came in a package deal with TYT radios. Buy the radio, get the PS for $20 -
That's a nice deal!
I bought one and it works fine here in Aus - but the Ammeter reads way higher than the actual current. It crept up over a couple of weeks.
Warranty?
Once again, you won the Internet this month with the He-Man reference! How old do we have to be to get that reference?
I'd assume 40s? Although I'm seeing a lot of Skeletor memes, so it might be coming back?
Will power supply be okay with a Stryker SR-955HPC? Is an amplifier required to use this power supply?
Yeah, definitely. The Stryker needs 12a. Make sure your power supply puts out more 12 and you're golden.
Thank you, my friend...@@temporarilyoffline
THANKS!@@temporarilyoffline
I have a 6W Yaesu FT-818ND and a complete newbie so I don’t have a dedicated external power supply for it yet… is this power supply going to be ok if the 818 is the only load or will it be too hot for it..?
Just fine
@@vk4foo Than you sir. SOLD. 👍
Yes, this will be a great power supply for the FT-818 - you can even add a tuner and an amplifier for 100w
@@temporarilyoffline Excellent, yes I've ordered one. I was shopping around awhile and whilst a couple available locally are a bit cheaper they don't have some of the protection features.
there is nothing like "too hot" power supply - for home QTH, at least 30 A capable power source is a must
That is a good option at a real good price.
I'm a fan!
Great vid
Thanks!
HI Steve Silly question, Does the meter have a light on it?
sure does
@@vk4foo Thanks, KO4HPC 73
Yessir!
Great video suggestion UA-cam. I am looking for one. I want to build a home vhf/uhf station.
This is a great place to start!
its under $80 right now, great deal!
Yeah, its a great bargain!
By the power of grayscull he-man has the power right not try again.
Right!
One thing to note, Astron are made in USA, the other in China. IMO that makes a BIG difference. Twice the price difference? For me in many cases yes.
Good point, thanks!
Put a scope on it and show us how clean it really is.
That would be great.
BUT....how long will the switching supply last? if switching supplies were quieter and lasted as long as a good linear, i would buy one in a heartbeat. the astron 35a linear supplies will last 20+ years with nearly continuous use. i don't think there is a switching supply out there that will last more than a couple years of continuous use, if that. so, in the long run, linear is $100 to $150 more expensive, but will last maybe 5x's or more than a switching supply. so, it is a no-brainer to go linear. portability would be the only reason i would use a switching supply. i'd get a good one like the one you have here, but it would not be a continuous use supply. field work, POTA, SOTA...stuff like that only. the total cost of ownership of a good linear unit is actually cheaper than a $97 switching supply. just my two cents. 73.
Thanks for sharing
Cause doesn't make noise it doesn't mean radio is happy, put an occiloscope and you will see all the a/c ripple that will scare you. Up to 1 a/c volt peak to peak on 40m, yes the frequency changes the ripple.
I'll have to get a scope to check that out! Thanks for the tip!
Wonder what amp that was? Hmmmm 😬
Its fixed now... I have to finish up that video and get it back in the mail to you ASAHFP - before it breaks again...
Actually I believe this is a knock off of the MFJ similar model. I have one and they work very well. MFJ contracts it out to Taiwan. Thanks...
Interesting!
I will stick with astron . More exoensive but so far never had an issue. , or yaesu fp-1030. Astron makes small switching ps's. But fir rf work i prefer linear over switching but thats purely a preference. If that ps works for you , stick with it. WA4UJY
Thanks for stopping by Joseph. I like my astrons too.
You're still a kid, sonny.
Old enough to know bertter, young enough to not care...
@Northern bloke. Yeah. It gets expensive at the "best regards" age.
There's nothing like good linear power supply. I know they are heavy, girls. You're just going to have to man up if you want quality, clean ( I'll say cleaner ) power. All power supplies are going to have some ripple. It's the nature of the beast. Also stop buying that Chinese junk that's poorly designed and made from low quality parts. Build a power supply yourself.
I can get behind building a power supply.
so its a rip off of the jetstream
Or Norjin, or Sky Top Power, or TekPower - they are probably all made in the same factory.
