    Good Power Supply for 100 Watt Radio

    Nice power supply. Runs my 100 watt HF Radio very well. Regulation is good. Fan can be noisey when running.

    Great steady low-noise power supply.

    I'm using this to power an Anytone AT-5888UVIII Tri-Band radio, Xiegu G90 radio, 4-port USB-A charger block, and 12v desk lamp. I had to put two diodes in series to drop the voltage for the desk lamp a little...it got too hot at 13.8. The power supply is steady and works well. I'm also using a 1-in and 8-out fused Anderson Power Pole distribution block. The unit has very little noise.

    Good for HF radio.

    I've been using this for over a month on a daily basis to power different HF radios at around 50-60 watts and doesn't even get warm, power is right at 13.8 volts. Tested at 100 watts for a few minutes held up just fine but I never push my rigs over 60 watts in actual use, so I don't know how it would run consistently on 100 watts of transmit power. Also, very important to me (and I am very picky) no RFI to the radio detected. With cheaper power supplies, I was able to detect some noise on different parts of the bands. Using the radio's screen, no RFI detected with this unit. Very happy with my

    Sky Toppower PS1330A power supply

    Works well for my Yaesu FT-3165. I would like the USB outlet to be 5 amp. It works very well otherwise, no issues.
