G'day Cobber, Thanks for the link to my video :) I think I started this whole step up 12v oven thing! Don't forget while the current draw is more, you're running the oven for a shorter period of time, and it actually saves on total battery usage, even with the efficiency losses in the step up. I have no idea why YT took so long to recommend this video and your channel to me. Great videos, I've subscribed and look forward to the next one.
Thanks mate, really appreciate the comment and feedback! Your video was what got me to grab one to start with and start testing it out, you did an awesome analysis of how the different setups worked. Hope to catch you out there one day.
Hey mate, as you are aware of the video i did on a stepup conveter, i used a 13.8 volt one which is (8v to 40v in and 13.8v out) as a 15 volt seems to much i reckon. I have spoken to Darren the owner of the travel buddy company and he said he has seen the timers burnout with 15 + volt converters so be careful. Cars dont usually give that much voltage out so a 13.8 volt one does work well and is safe. Cheers.
IMHO, it is safer to focus on improving efficiency given the general application of such units. This can be improved by making sure to use a high quality fuse or breaker with no voltage losses. (if the fuse or breaker gets rather warm, it is wasting energy as heat) Further efficiency gains can be had with external fibreglass insulation on the cabinet with secondary external metal housing but I would not insulate or block any door components and or ventilation holes. This is just the opinion of someone who has tested on a particular brand of oven as there are variations in quality and components throughout the range. Voltage converters of any kind reduce efficiency and safety. components eg timer/thermostat can burn out as this style of oven are generally designed for no more than 12-14v nominal. I would not use a 15v boost regulator under any circumstances. I would always monitor an oven in use, particularly if any modifications have been done.
Great video, thanks. One thing I’m not quite sure about is whether you use this while driving or not. I understand it suits use for when not driving, but can you use it while driving? Also, what size battery would you recommend to be able to use while not driving? Thanks.
Hi Rox, Yep you can still leave this all hooked up while driving. Up to the step up converter input, your 12v system will still operate and charge at 12v as normal. It’s only after the step up converter that the voltage raises to 15V
@@Roxlivinlife ive done a video on the 13.8v one, mine is 8v-40v input to 13.8v output, i went this one because i could use in my car on 12v or boat which is 24v.
Yeah good vid mate, I like the idea of this mod, I have a Kings Oven, only used it once so far, 2 pies unfrozen took 50 minutes & were perfect, I would like to do this mod tho & speed it up a bit. Have you checked what temps ur TB cycles at on max setting, or does it not cycle on the thermostat when set on max and just runs flat out at 14A-15A continuously until u turn it down or off? TF. Cheers
Sounds good mate, the TB does cycle at max temp but so far I haven't put the thermometer in to check the actual temperature. I will be doing this test though so I'll be sure to post the result.
Be careful. I bricked my Travel Buddy using a 15V Step Up Converter!! 15V was too much for it internally. I ended up rewiring the TB and went to a 13.8V converter and it's perfect.
So, was it just the wiring u had to replace, or were there other components like the thermostat, timer or element damaged in any way? i would expect if the thermostat could handle the extra wattage, it should keep it within certain heating parameters, but I dont know how hi they let the temp go before clicking off & cycling at around that predefined temp. Do you know what temps it could/would reach & cycle at?
I ran the 15v step up and found my oven turned off, died , unpacked it and the main wire going into the timer had burnt off 😳, also noticed the cable going to the heat element had turned from red to a brown so I think that has coped a bit of abuse from the extra amps heat applied so managed to rewire what was damaged and oven has come back to life but think I would leave it stock or 13.8 step up , otherwise I think 24 v model oven heats up even quicker than 15v step up on a 12v , but all I can say is be cautious
Nice work, now do it with mini pizzas and with pies. ( real world stuff). Keep the vids comin, just subbed to you. Any chance of a big bertha work over ? Cheers, Simon ( Sundancer)
Sounds good to me Simon, any excuse to cook up a pie or pizza 😂 I’d love to do a big Bertha comparison. I’ll have to find someone with one to a video with!

I reckon I’ll have to look into dropping back to the 13.8V 👍🏽

Hi mate does the step up converted need to to be disconnected while driving? Or can I just leave it plugged in the whole time?
When driving would you disconnect the step up converter or does it not matter ?
Mate does it matter if ya getting solar or alternator charge in with the converter connected?
I have a 24v one, and runs nicely when the sun is up and the batteries are at 27v.
or when I'm driving and they are at 28.5v
I’ve heard a lot of good things about the 24V units. Got a few truckie mates that rate em really highly 👍🏽
@@OutNAboutAustralia I have a video about it going public next week.

First in, first pie is mine.
You still using the 15v step up or you dropped back to 13.8
I’ve dropped back to the 13.8V mate.
I wasn’t having any dramas with the 15V but I kept hearing the horror stories.
awesome eh.
Love it!
