Product Description

Introducing - The N8XJK SUPER BOOSTER!! Now with up to 40 Amps Output Power and a Thermally Controlled Fan for cooling!!

This unit has the same basic functions as the original unit, but with following added features:

1. A Thermally Controlled Cooling Fan for maximum continuous use. Now up to 40Amps of power can be achieved, without the worries of overheating. The Fan only runs when the unit heats up.

2. External adjustments. You can adjust the voltage output and the RF delay from the front panel.

3. The new RF Delay circuit. The delay circuit allows for a delay to be added in between RF enabling for smooth transmissions.

4. The New Remote Terminal Strip. This allows for remote control and monitoring with a pin type termal strip. You can externally Enable, Monitor Input voltage, Monitor Output voltage, add extra low battery and enable LED's, plus has a 12volt source voltage for powering an external circuit. Check out our Remote/ Meter Panel, which connects to the terminal strip

5.  The Low Voltage Piezo Alarm is available for this unit.  Just click the Alarm option when placing in shopping cart.

Thanx for the reply. I may move the low voltage cutoff up to 10 volts. Got the unit hooked up this afternoon. My minimum load voltage is 14.48, and full key down at 100 watts output is 13.5. I use a Kenwood TS140 off my deep cycle battery on the trailer for field day. Never got more than 80 watts out. Now I get the full 100 watts out. THERE IS NO DETECTABLE RFI!!! I'm kind'a sensitive to that, because I'm a retired EMC engineer. I wish some of the boxes we put on the Mars Reconisance Orbiter were that quiet. Congratulations on one of the best new products to hit the Ham Radio market in a long time. All the Best, Clyde

  1. Solved the problem 5 Star Review

    Posted by on 13th Sep 2015

    Sept 12th I took my size 24 deep cycle battery, tranceiver, and my recently purchased N8XJK super booster to the field in the Ohio State Parks On The Air contest. It rained all day but the super booster functioned as advertised. With the output set to 13.8 vdc unloaded, I was able to maintain 13.6 vdc to, and 100 watts from the tranceiver even as the battery was depleted to 11.8 vdc. If your radio suffers from reduced power at reduced voltage, this is the device for you.

  2. Amazing Piece of electronics. 5 Star Review

    I have been looking at purchasing one of these for about 2 years as i use my radio (ic706 mk2) in a portable locations on a regular basis,it has lived up to all my expectations and delivers everything that the product description states, i am about to go on a 6000 klm out back adventure wher i will test the product to the full.

  3. Built like a tank. 5 Star Review

    Posted by on 25th Feb 2015

    I have recently received and installed this power booster regulator and am extremely pleased with it. My radios run on power from three solar cells, so there is no downside to this unit at all. It works as advertized and every signal report I have received has been excellent.
    Thank you for building such a great product right here in the State of Michigan and bucking the trend to outsource overseas.

  4. This "Magic Box" WORKS! 5 Star Review

    Posted by on 22nd Jul 2014

    I knew what I needed but wasn't sure if this was it. I wanted to operate rover and with engine off because we all know what happens to a IC706-G when the voltage drops... In the last CQ contest and from one spot, I operated for 2 hrs without ever starting the engine.
    I didn't adjust a thing, ran it just as received.
    The only option added was the 40amp circuit breaker. Directions state "keep input/output power cables as short as possible. I ordered the longest cables as I wasn't exactly sure where to mount the unit. I mounted it behind my center console and didn't cut the cables short.
    This didn't seem to affect operation in any way I could tell. This is the best option you can add to your mobile station.
    Why didn't I buy this magic box years ago??

  5. Exactly what I needed and works just as advertised! 5 Star Review

    Posted by on 20th Jun 2014

    I have used Icom 760mk2g, 7000, and 7100's in my vehicles for portable operations and they are all "sensitive" to low voltage dropouts. Car running, all is fine, however, try to transmit > 50 watts and the units would reboot. Kinda discouraging.

    Eventually, I decided that since I like to operate /P - the gear is in my car, but like to go out a lunch and have a QSO or two - I'd purchase the booster and give it a try. Not a single regret - not one... The booster is set for 14v and the 7100 could not be happier!

    Quality of the product is fantastic; for some reason, I thought the case was plastic - NOPE, rock solid and durable.

    If you're on the fence, jump off and place the order - you won't regret it!

  6. Great product that really deliveries 5 Star Review

    Posted by on 13th Apr 2014

    I use battery power for ARESĀ®/RACES events. This battery boost stands up to heavy and constant use. I would recommend this unit over all other manufactures.

  7. TG Booster delivers the voltage. 5 Star Review

    Posted by on 3rd Apr 2014

    Fifteen minutes after receiving the Super Booster it was hooked up to the Deep Cycle Marine Battery and to the IC-880. My digital volt meter showed 14.1 vdc. After one hour of operation at all three power levels the voltage was still 14.1 vdc. When the Super Booster was turned off the volt meter showed 11.4 vdc. Great job!

  8. A great product 5 Star Review

    Posted by on 14th Jan 2014

    Installed in the mobile a few days now with icom ic7000"which took,a,dive in output power at 12 volts. With the booster set at 14 volts radio runs at full 100watts .excellent build quality .
