Almost every truck in the world today already has a 13.8 volt DC system. I don't think this is what you are looking for. **Q: Thank you for a fast and rapid answer, do you also have these units in 40 or 50 amp? if yes, please advise where to purchase?** A: At this time we only carry 30A units **Q: Is the dc "negative" electrically connected to ac neutral? is there a jumper to remove?** A: you can but for safety reason you should not. Most of the electronic gadgets have isolation transformer. If you do this then you are defeating purpose of the isolation transformer. **Q: Where can I find the different cables that would work with this?** A: They do not make cable for this. I made my own being a Amateur Radio Operator and my experience installing old style phones in cars and Two way Radios was helpful. ## Customer Reviews ### ⭐⭐⭐⭐⭐ "No Issues" Power Supply. *by on Reviewed in the United States 10 June 2026* Solid power supply so far! More than enough power to drive my btech 50 W gmrs base station. No noticeable noise output in received or transmitted signals. Voltage regulation is dead on. There are cheaper supplies available, but I like the build quality and performance on this one. No regrets at this point. ### ⭐⭐⭐⭐⭐ Works great with my FT-710 *by on Reviewed in the United States 22 December 2025* I purchased this Btech powersupply because it was very reasonable/low cost as compared to other manufacturers. Prices on powersupplies have gone up a lot, but Btech has the cost within the range I needed. In addition, Btech has a good reputation on radio and power supplies.I use this on my FT-710 and an external tuner.Have not had any issues at all. Delivers a solid 13.8 volts. Voltage can be adjustable, of preset to 13.8 volts (via a switch in the rear). Power to my FT-710 is clean and no noise or buzzing. I usually drive about 6 amps from this powersupply.Happy with this product. Does what it needs to do for a reasonable cost.Update: 1/17/26: Been doing a lot of FT8 work several hours each day. Pulling about 13 amps on each transmission. No issues at all. The top of the power supply (heat sink) does not even get warm. Really like this power supply. ### ⭐⭐⭐⭐⭐ Great Power Supply for HAM Radios *by on Reviewed in the United States 25 November 2025* I bought this power supply for powering HAM radios which is its intended use.It has three options for connecting loads:* Banana plug/wire terminals on the back (30A)* Car cigarette lighter style socket on the front (10A)* Cable clamps on the front (3A)It has the option to switch the output voltage between a fixed 13.8V (which is 1.2V higher as the nominal output voltage of a 12V vehicle battery or similar) and a variable output voltage between roughly 8V and 15V (the switch for toggling between the fixed and variable voltage output is on the back panel, which is not a bad thing as it should prevent accidental change). The supply has a display showing the output voltage and the current. I have measured the variable output voltage with a 6 1/2 digit multimeter and the readings are within less than 100mV.Given t's 30A maximum output current it should theoretically be able to supply up to 450W, albeit I have not tested that. However, that should be sufficient to easily provide power for multiple radios in standby receiving mode. Even when transmitting at 100W on one radio it still has sufficient headroom for the other radios. The maximum current of 30A is only available through the clamps on the rear of the unit.It is a switching power supply which keeps the form factor small considering the power output. I have not measured the switching ripple/noise. If that causes problems on the receiving frequency through audible sounds, there is a knob called "Noise Offset" which allows to shift the switching frequency. I have not had any problems with noise though. ## Frequently Bought Together - BTECH RPS-30PRO 30 Amp Regulated Universal Compact Bench Power Supply, AC-to-DC Power Convertor, 13.8V (9~15VDC Adjustable) with Noise Offset Adjustment, includes multiple power connections - BTECH GMRS-50V2 50W 256 Fully Customizable Channels Mobile GMRS Two-Way Radio.
