You're surely not going to be connecting any wire bigher than 12 awg. On the back of the power supply is two binding post. Use solder to make your lugs up on the wire. You'll have to remove the plastic sleeve, about two or three twist with pliers and that sleve will come off. Strip and dress up the ends of the wire. Solder the lugs to the red and black wires. Let cool and the you can hook up your device. I hope this helps, at any hardware store you can get the terminals you need. **Q: If I use this to power a car amp can I hook up a capacitor also like a car setup?** A: Cody, yes theoretically you could since the purpose of a capacitor in a car audio system is designed to prevent large spikes on your battery/charging system by your amp... It would do basically the same thing, I would recommend watching the display for how many amps you are drawing as you slowly turn up volume to make sure you don't draw too much and damage anything. **Q: what is the difference between the tekpower tp30swv and the tekpower tp30swii?** A: Digital readout on the SWV vs analog dials on the SWII. **Q: Is this Power supply too noisy for ham radio?** A: I don't know.... my SMPS failed after two days running a load of less than 4 amps. I don't recommend this unit under any circumstances, especially powering a ham radio. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works Great! *by C***T on February 6, 2020* I've been using this 24/7 for several months to power my HAM and CB radios. It has never faltered or lost it's set voltage of 13.8 even when drawing 10+ amps. Feels solid, looks good, heavy. I have this setting next to my radios and it has never induced noise that I can detect or a listener can detect. Great power supply. I will probably buy another one when I expand. I like that the voltage is adjustable or your can use the default set adjustment of 13.8. The digital display is easy to read and displays amps as well as voltage. Love this thing. ### ⭐⭐⭐⭐⭐ Great Power Supply for your Money *by R***H on June 5, 2024* I was searching for a first power supply for my UHF/VHF mobile, this has the cigarette lighter port that allowed me to get the radio powered and on the air. The panel displaying the voltage (I used the selector for 13.8V fixed) and the amps simultaneously lets me see what my radio is drawing on each band and power setting. The binding posts on the back will be utilized with a ring to powerpole cable and dc distribution panel and new cable to radio setup. This will allow the power supply to supply all my device connections for current and future use. The cigarette lighter port will get a USB charger adapter to connect my 12dc laptop and charge my HT radios.Overall a great first power supply to get you going. ### ⭐⭐⭐⭐⭐ Highly Recommended *by E***S on December 15, 2015* I bought this to power a sub/amp setup that I had taken out of my old car when I got rid of it. I was unsure if it would have enough juice. Two 300 watt rms alpine R-12s paired to a 600 watt rms alpine amp. Everywhere you read, people will tell you that the math does not work since this thing is only rated at 30 amps but I'm happy to say that it works like a charm. The subs slam hard enough to vibrate all of my doors in the basement and pictures on the wall in the rest of the house. And going by the digital readout on the front, the power normally stays in the 5-10 amp output range during bass heavy movie scenes and lower when listening to music at normal levels. So it clearly has the headroom to power an even more powerful setup if that's what you have. I highly recommend this to anyone looking to do a reliable, clean and SAFE conversion. ## Frequently Bought Together - TekPower TP30SWV 30 Amp DC 13.8V Digital Switching Power Supply with Noise Offset - RFAdapter RG8x Coaxial Cable, CB Coax Cable, 50ft UHF PL259 Male to Male Low Loss CB Antenna Cables, 50 Ohm for HAM Radio, Antenna Analyzer - Lightning ARRESTOR for CB or Ham Base Antennas - Workman A28 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/11334252-tekpower-tp30swv-30-amp-dc-13-8v-digital-switching-power](https://www.desertcart.tn/products/11334252-tekpower-tp30swv-30-amp-dc-13-8v-digital-switching-power) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-03*
