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. ## 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.fr/products/11334252-tekpower-tp30swv-30-amp-dc-13-8v-digital-switching-power](https://www.desertcart.fr/products/11334252-tekpower-tp30swv-30-amp-dc-13-8v-digital-switching-power) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-08-26*
