  1. Excellent workmanship and quality 5 Star Review

    Posted by on 7th Apr 2017

    I opened mine up to see the low voltage adjustment jumper I was happy to see the excellent build quality of this unit. Looks bullet-proof and should last forever.
    The unit works very well and my rig is so glad I bought it. I have it mounted in my portable radio station which takes some jarring from time to time but I'm not worried a bit as the box the Booster is built in is a very strong metal one. I'm very happy with this Booster.

  2. Second one just as good as the first 5 Star Review

    Posted by on 5th Jun 2015

    This is the second one I've bought and it's just as good as the first. I use them for my ham radios when I'm running on batteries and I never have a noise problem. One is mounted on a portable cart with a solar controller, batteries and an inverter and the second one is permanently installed in my travel trailer.

  3. Wouldn't operate in the Field without it... 5 Star Review

    Posted by on 18th May 2015

    I have recently purchased my fourth, or is it fifth, Booster from TGE.
    Whilst it hasn't arrived yet I feel compelled to put some words together about these units.
    As per the title, this is an essential part of my field kit. Right now I am building a Marine Booster into a field UPS system that will take Ext DC in (Pwr Supp, Vehicle, Solar, etc.), charge & maintain by Field Bty, and through the magic of the Booster give me a steady and reliable DC source for my equipment.
    Why haven't I said anything about the TGE units? Because they are so good and reliable, they just sit there and go, there is nothing to say.


    I should also mention. Over the years, the support from Tim has been excellent. Always ready to assist and advise.


  4. Excellent product 5 Star Review

    Posted by on 10th Feb 2015

    I've only had mine for about a week, but it is performing exactly as advertized. I'm using it to maintain 13.8 volts to my radios while connected to my solar-charged battery bank. While charging, the battery voltage can be as high as 14.5 volts and after a couple of cloudy days they may drop to 11.9 volts. The output from the boost converter has been constant across the range.
