Thanks Lock - being a retired Avionics technician I will er on the side of caution and potentially ☺️(no pun intended) try the 13.8V regulator only to protect the oven over long term use because I don’t want a raging fire while driving down the highway - I’m at my third stage and three years in to the Hilux/Aluminium canopy/RFT project build with many prototype setups discovering what works and what doesn’t - I’ve gone with a simple 100ah Amptron Lithum battery system incorporating Redarc, Renogy, Engel mane even Kings products because I only run lights, 27 litre fridge and Sureflo water system - my Travel Buddy is on its way so I’ll start with a simple high capacity/fused/relay configuration first an monitor current draw and heat which are the two important elements that can destroy a system and your vehicle.
There's nothing wrong with a conservative system, while I like fiddling with all the latest tech like induction cooking and air fryers etc, most of the time camping, I run a fridge, lights and usually cook on a fire.
While I'm not sponsored (I wish!) I've become a bit of a fan of Victron's gear. The customisation and versatility is unmatched. I'm running a Cerbo GX (their comms hub) on a Raspberry Pi (Venus OS) so can monitor any of the systems parameters anywhere I've got internet.
Though, back to the TB, I've been running the 15V stepup for a few years now without issue. Seems to work ok.
Well done mate. Great reviews
Thanks mate!
Thanks mate. Very helpful.
Glad you liked it!
excellent stuff mate - thanks
You're welcome!
Nice! Good info and great explanation/demonstration and results. Thanks again.
Cheers mate, glad you enjoyed it!
Brilliant video, great info,cheers
Glad you enjoyed it
Thanks mate, brilliant stuff.
Glad you enjoyed it!
Bloody awesome video guys! Gotta love your tips, especially when the proof is provided, not just opinions like many other channels.
Thanks mate, yep opinions are like belly buttons, everyone's got one! The truth is in the testing data.
Nice video, very informative.
Glad you liked it!
I really like your videos on the DC systems.
Good, comparable, repeatable results.
Great stuff!
Thanks!
awesome job mate, made it so easy to understand where you were going with it but i was so interested in the info. keep them coming.
Thanks mate, appreciate the feedback!
Love it. Great stuff. Off to ebay now!
Thanks!
Another top bloody notch video guys 👍 Well done!
Rito, enough of pumping up your tyres..... I've got to get on Ebay 😂
Thanks mate, you had better "tread" carefully with comments like that, my ego might get "over-inflated"! Ok I'll stop there.....
Great video. Was keen to find a solution using the Buddy when not driving and when sun wasn’t optimal for solar... now I’ve got one thanks to you... Cheers 🍻
Glad you enjoyed it!
which one did you get?
Superb video.. solid technical presentation from someone who clearly has a very firm grasp of the subject matter! I run a cheap Jaycar 12V warmer, only room for a couple of pies and you have to leave it open for the last 20mins of cooking to dry it out a bit.. but does a great job and doesnt take up much room. Those stepup converters are an interesting bit of kit at what looks like a pretty fair price.. thanks for the information and ideas.
I've tested those as well, for only a couple of pies, they hold up well in comparison!
Well presented
Thanks!
Well done on this video top demo 8)
Cheers!
Another great video, well researched and tested - thank you. Hey you could have your questions regarding longevity answered by asking Aussie Dave Jones from EEV Blog - he'd love to sort you out I reckon. Shoot him a mail or send him the link to one or more of your clips as his motto is "don't turn it on - take it apart" and he's a Guru & Aussie. Cheers mate.
Haha, I like he's motto!
Love the idea, will probably do this even though I Run a lithium atm.. Just want to make a note, that the factory wiring that come with it most likely could do with an upgrade.. Especially as it has a 1tamp blade fuse and most likely 15amp rated wire... I'd definitely be putting 12g (25amp) cable on and a 20 amp fuse
That's a great suggestion.
I added a 15v converter to mine today. Oven now too hot to touch after 45 mins. Such an improvement. I found the stock blade fuse on mine was adding too much resistance so changed that out to something better and increased voltage to converter by 0.3v. All adds up
It sure does! It's a shame Midi type fuses don't come in lower amperages suitable for the TB.
You'll love the 15v conversion, it really does transform the TB for the better.
@LockyourHubs4WDing thanks for the great video even though a few years ago. I'm getting near 180w into mine now. Shame it's over 35 every day so yet to test it properly. I went with a circuit breaker in the end so I could easily disable the converter as required. The blade fuse was clearly a massive resistance point.
I did some testing today on my new Rough Country travel oven. I found the element was about 1.6ohms using a four-wire resistance test (no wire leads or fuse included), and using the figures from the 60V/100A power meter is was about 1.7ohms (including wiring, fuse and the power meter itself). I ran with a 135Ah battery only, which dropped to around 12.05V with a current of 7.2A and power of 86W. I then added a 4A battery charger where the battery settled under load to 13.98V with a current of 8.1A and power of 113W. Lastly, I put two small motorcycle AGMs in series and it was running about 22.3V under load with a current of 12.8A and power of 285W(!). I cooked a couple of pies that way. I thought it might go "pop" and let the smoke out, but it went fine...for now. Cabling was a little warm ;-) This was done on a concrete floor, not in-vehicle. I'm not staying with such a high voltage. It was just for fun.
Generally, anyone wanting to work out the current draw in this type of oven can use 1.7ohms as a starting point. Divide your chosen voltage by 1.7 and you have your current in amps, which is the output side of the step-up converter. The current going into it will be higher, though these boost converters usually have a larger wire size on the input side to allow for this. The limiting factor, apart from the element, will be the 15A fuse and the wiring, which I'm leaving alone. My stove is rated 100W, while I see Kick-Ass specs say 130W max. I'm guessing there's not much variation between all these brands, but you never know.
I'll be getting one of these step-up converters, that's for sure. Thanks for the great video. Well presented data and charts. It's good to see. New subscriber.
Some great info, and 22.3V! Wow, I thought I was keen with 15v!
Really great video, but yes it was drawing more amps from the battery at 15v but it was actually pulling more watts through the oven. So the first test doesn't really show the efficency all that well. What you needed to do was test the current on the other side to view in and out. But final test showed the end result anyways.
I don't think the efficiency of the step up itself is all that important other than academic intrigue, what is important is how much battery capacity you use in comparison with the other options.
As a straight resistive element in the travel buddy you will find that raising the voltage raises the current draw anyway due to ohms law. So the losses through the converters probably aren’t as bad as indicated here anyway. You could measure the current with a clamp or inline power meter to compare the oven current vs the battery current.
It's definitely Mr Georg Simon Ohm responsible here!
I have a kings travel oven and i put 2x frozen saussage rolls in and from cold start it was done in 50 min no pre heat .
That's impressive!
FYI,
170W @36minutes is 102.6Wh
145W @48minutes is 116Wh
120W @80minutes is 160 Wh.
Even though the step up converters are not 100% efficient and do loose power to heat, the oven is also not 100% efficient and also looses heat over time.
Thanks for the clarification.
This was a sensational video mate, well done to you. I was screaming at the screen “what amount amp/hrs” when you were showing the heat up times, but true to form you covered that off in the end. I’m sold, just bought one! Again, thanks from Jafffa Adventures for educating me.👍
I thought there might have been a penalty to pay, but for pre-heat, it doesn't look like there is.
Though for actually cooking... How long is a peice of string? Thanks for the kind words mate!
Lock your Hubs 4WDing I run a 120 a/hr lithium battery and as you noted it holds 13.8 volts right down to its 20 percent cutout limit. I would love to see you repeat these tests in this video on a lithium battery. Your results might show me I just wasted 20 bucks 😂😂. Thanks again.
@ Jafffa Adventures did you charge your power tool battery in the car ? What you use for it the get the 18v battery charged
Great videos you do. Very informative and helpful. If these step up/down convertors are 12v input, 13.8v(or 15v) output, how do they handle it when the car is running and the input voltage could jump up to 14.5v? Can they handle that?
I've seen a different model 13.8V model that handles a much wider input voltage range, like the one that Somerville Metal Works sells. Though not for the 15V version. Though with a little extra wiring you can automate it switching in and out ua-cam.com/video/CT6WJNPNRsc/v-deo.html
I got the 13.8 since it's the same as my alternator but I wish I got the 15v now!
It certainty adds performance!
Thanks for the video. Very informative. One question though…what step up converters are you using?
15v!
Great video and loads of good tech data! My alternator runs at 14.4v so 15v should be fine, but curious if the ovens have a voltage limit before things break? What stopping you using a 24v step up?!
You'll eventually find the limit of a component or two, or maybe the wiring.
I prefer mrs macs

WOW! Bloody great video, thanks so much, so in theory this data would replicate for a 12v Fridge running from a similar set up???
I tried it with an Engel 75 Combi, we got better performance, but used more battery capacity.
Thanks for the reply 👍🏼👍🏼
1x 13.8 left in stock as of 4th January 2024
The 13.8 makes sense, as said being a charge voltage which is way you use them when driving or hooked up to a battery taking a solar charge. They can be used off stand alone battery but it's not an ideal situation. On a sla performance is only going to get worse as the voltage drops. Interesting to see results long term. I can imagine it impacting on the oven much at all. If any wiring couldn't handle that small increases, I'd be a bit disappointed. If be interested in that Guage of the nichrome heating element and if you could wind another to improve performance. Likely not worth the effort though.
I don't think a modified element would be worth the effort, a second element though.... Just need to convince TB to sell me one! (They wouldn't sell me one....)
@@LockyourHubs4WDing you can buy nichrome heating wire for vaping . it comes in different gauges and there for different resistance/foot or length. i reckon with a bit of fiddling and measuring, you could set up a parallel heating element to run with the original. one on top would be nice..ooooh and a fan. anyway, my roadchef is on it's way thanks to your vids. I like aussie built and try and promote aussie stuff on my channel but there was too much going for the road chef to make me buy the buddy. i would have happily paid the premium to buy aussie if it was an equal or better product. oh well. cheers for the vids. I like your more technical approach to the items. nothing shits me more than an unboxing video with info I could have read on a website. PS I'll give you a shout on my channel when I get around to doing my review on it.
@@DENMONKEY My ideal TB would have a digital thermostat/timer, insulated door with overcentre latch, 13.8v step up that cuts in and out with the charging voltage, and your idea of a fan is great, there is a large temp differential when running both stainless steel trays in the oven. And don't forget the second element! I've just seen your channel and subbed, thanks in advance for the shoutout!
@@LockyourHubs4WDing cheers. I also checked out your winch ring vid. that was interesting to say the least. I hadn't checked them out first hand but I thought they had a bearing inside them. I imagine the pressure on them would make that not possible. Im wondering if the heat generated from that additional friction has any long term impacts on the rope.
@@LockyourHubs4WDing yeah that’s the new KickAss glass door oven you want. Has a digital temperature gauge and an oven light.
They are purely a resistive load - A length of nichrome resistance wire, more or less.
Not a lot to go wrong, and makes them fairly tolerant to different voltages, but I wouldn't push them much further than 15v
I use a 24v version, and it's a bit slow dead on 24v, but nice when the sun is out and I'm at 27v, 28.5 on the road and it's beautiful.
Yep the 24v unit runs great! There's an episode on the channel comparing the two.
@@LockyourHubs4WDing I'll look that up, I'll have a couple of videos of my own coming out soon. I have a 6x6 ex military land rover.
@@TheAussieRepairGuy Nice, the 6x6 Perentie with its turbo Isuzu engine is a great thing!
I look forward to checking out the videos.
@@LockyourHubs4WDing I have a 4x4 gs as well. I'll let you know when they go public
Brilliant video as always! Have you tried leaving this plugged in while driving? I wonder what happens when the input voltage is say 13.6.
I haven't, at the moment, I just swap around the plugs, though will automate it soon.
Have you tested this out yet ?
@@kontiii I did one better, I did a video on how to wire up step-up convertors with a switch, relay or a fully automated solution depending on your needs and still staying in the specified voltage range. ua-cam.com/video/CT6WJNPNRsc/v-deo.html
@@LockyourHubs4WDing legend
Hi mate, great video I got a step-up converter and works great on my AGM battery, but I have just upgraded to lithium 150ah would there be any benefits using it on a lithium ?. Would it work the same ? Cheers
Still works just as well.
Interested to see the results with 12v fridges as well my trailblazer fridge is 12v to 24v
Here you go! ua-cam.com/video/m9xjYKs1Kx4/v-deo.html
Just the information I was looking for, thank you, can you let me know where you got the 15 volt step up converter from? I've had a look around and, and can find 12v to 15v, with a max output of 15 amps, do you think that should be fine considering you hit around 13.6 amps draw, or should I look for 20 amps max?
The part number I used is in the description.
Hi mate great video ! Could you tell me what size wire is used on the step up converters you are using ? I brought one off eBay for my travel buddy last week witch looks identical to the Amazon ones you are using but the cable is only 1.5mm 10 amp witch I’m not real keen on trying but seems a lot of people use these same ones so just wanted your feedback!
Thanks Chris
I was just using Anderson plugs for the testing, though for the actual installation, it's going to depend on the length of the run of wire.
Let me know how long your wire run is back to the battery or distribution point and I'll tell you the right sized wire.
@@LockyourHubs4WDing thanks for the reply mate ! What size cable is coming out of your step up converter is what I was after ? Cheers Chris
@@chrisharding795 Oh ok, sorry I misunderstood.
With the 15v Step up, taking into consideration the power usage (13.6A@12.6V) and the length of the run (0.3m) that works out to be 18awg or 0.823mm^2 wire minimum to not loose more than 3% in voltage drop.
Though there are connection resistance losses as well. Best thing to do is run it for a while. If it's getting hot from the electrical energy passing though it, time to upgrade! Though I say it should be fine.
Has anyone checked the output of these when the alternator is pumping in the juice? Would be very interested to know what they do when the system is running at full charge of around 14.5v. Thanks for the great content and thanks for any further info.
If you check out the travel buddy FB group, I've uploaded a wiring diagram that uses a switch to bypass the step up when the car is running, you could easily enough automate it with a relay and a trigger from the "on " position on the ignition.
Do you think these step up converters are sealed good enough to be mounted on the back of a tool box in the weather? I have wanted one and this great review has sold me on one. I have always held off due to mounting positions.
They're advertised as waterproof, so as long as the connectors are weather sealed, I think you should be fine.
@@LockyourHubs4WDing yeah nice. Cheers. Best be hitting ebay! Will be between toolbox and ute cab. So not in straight view of weather.
My Chevy Silverado is fitted with three Fyrlyt Nemesis (250 watts each) driving lights. Fyrlyts are made in South Australia and the nemesis model is a 24volt halogen globe and is supplied with a 12v > 24v step-up converter...look the same as the ones in this video, but with higher output. They are designed for all weather use; mine are mounted on/under the bullbar. No worries...
@@billroach2393 Great thanks, good to know that not only are they advertised as weather proof, they actually are!

If the voltage input range is wide enough, no problems. Though keep in mind, these step ups have a little current draw even when not actively powering the oven.
@@LockyourHubs4WDing thanks heaps for the prompt reply. Love your videos
Hi can you please do a temp comparison between the 12v and 24v Travel Buddy? I would also be keen to see the Amp draw between each and how much Amp Hours over time for the same cook and how long each took. I'm looking to use a 12v to 24v converter for this and would be interested to also know how much extra Ah that adds to the battery consumption instead of a direct 24v source.
I was just chatting about that last night, I think I might in the near future.
@@LockyourHubs4WDing I am concerned also about the under side of the oven getting hotter and so I thought another way of increasing internal oven temperature and lowering external temperature would be to use a heat shield. I found this one that seems perfect for the job reducing heat by up to 90% making a 50C external temp just 5C. If I pull the trigger for the 24v oven, I'll try this as I have a fridge that will be just 2.5cm below the oven.

I meant to say thanks for the idea, it turns out they do, for my Engel anyway. ua-cam.com/video/m9xjYKs1Kx4/v-deo.html
Got myself a SMW set-up converter... my question is fuses...
One before that 15amp?
Any after the set-up for safety of over?
I would place a fuse close to the power source (battery I assume) and another after the output of the stepup.
I’ve just purchased the 15v converter, what’s the go with fuses, do you install 1 on the input and out put sides? I already have 1 on the travel buddy wiring so was thinking on the out put side would be over kill?
I would place a fuse on the input and output as close to the supply of power as possible.
G'day, I know this is an old vid but hoping you maybe able to still answer a question.
Is there any recomendations on where the Stepup converter (15V) should be in relation to the travel buddy "Distance from travel buddy to Step Up Converter)? or doesnt it matter?
Ill be putting in a switch at the dash area but travel buddy is in the back of the wagon. I was thinking of hiding the converter for clean wiring.
Enjoy ya vids. Thanks.
G'day Phil, just like a DCDC battery charger, you're off placing the DCDC step up as close to the Travel Buddy as possible.
@@LockyourHubs4WDing Thanks mate really do appreciate you getting back to me on this even though its an older vid.

Basically, I have now a 100ah Lithium in the back just over the top of the travel buddy just so you know. I purchased the 15v Step up, but as you said in your vid, "you cannot speak to the long term durability on the 15v " but hoping by now maybe you have better insight?

Where did you buy the step up converters? Was it just eBay?
Yep, eBay special!
I have a question...what would be the results if you used a 12v dc dc charger and attached Anderson connectors to the input and output sides of the charger..then put it between the battery and the travel buddy..the reason I say this..is that I have swapped out a 12v dcdc charger..so I have one lying around gathering dust.
Depended on the output voltage of the dcdc I suppose.
Nice video, thank you
Just to be pedantic, the saying is not. “The proof is in the pudding.” It is “the proof of the pudding is in the eating”
Haha!
Actually it's either. In the USA it's "the proof is in the pudding ". In UK it's the latter. In Aus, it's either.
Could a similar test be done for operating off 240v to 12volt convertors? Difference between a 13amp compared to a 15amp unit. I noticed a lot people are using different amp converters.
If the 240v converter can supply enough amperage to the oven, it doesn't really matter if it's 13amp, 15amp or 25amp. There should be no difference in performance. The oven will only draw as much amperage as it needs.
@@LockyourHubs4WDing Thanks for the quick response! Love your video's.
is the correct model for the 13.8 unit XW-12-13.8-248W (12v-13.8v18A) ? I am not super with my 12 V just want to make sure i get the correct one?
Thanks
It's the XW-12-13.8-248W That looks like the right one.
So what happens when you set it up and car is still running? Does it max out at the 15v or boost past that?
Various step ups have different voltage limitation. I know there is a 13.8V step up avaliable through Somerville Metal Works that has a wide enough input voltage range to just connect it up and not really worry about it.
Though for the 15V, I've only seen them with a 11-13V input. You can either manually switch it in and out, or automate the process with relays. I did a video with a few wiring diagrams you can download and print out if you're interested.
G'day,
Can I leave a 13.8v regulator in when alternator charging or with solar input? Run an old school isolator and a separate renogy rover mppt for solar.
Check the input voltage range, but most you can.
@@LockyourHubs4WDing I have run it hooked in with solar going for a few hours twice. Never saw a problem, thought I'd ask for some expert advice to be safe.
Thanks for ya reply.
All the best,
Luke.
Hi. Just a thought. Is there any reason why you cannot run these units direct from the alternator?
Via the battery? The limit in the specs is 13v input, and many cars charge at a higher voltage than that. There are some step ups avaliable with a much wider input voltage range, though they're 3 times the price. Keep an eye out though, as the next video is all about fixing the input voltage limitations.
Gaday mate,
I have a late model Patrol with a so called smart alternator. I’m assuming that using the step up converter whilst driving, will still be beneficial even though the alternator kicks back to 12.?V about 2 minutes after you start the car?
Sure will!
@@LockyourHubs4WDing thank you. Can you tell me, for a quick safe initial setup, could I fix the step up converter in line to the back of the oven with Ceramic 10mm screw spacers for ventilation, 15amp in line fuse then battery supply?
@@GPatrolUte Solid state electronics don't enjoy heat, while the ceramic insulators will help, a sheet metal spacer with an air gap each side will be much better.
@@LockyourHubs4WDing Cheers and many thanks👊
Great video... do you have a link to the actual unit (15v please) that you used in this test...
I want to get one.

Lock your Hubs 4WDing wow, so the 13.8 one actually uses a fair bit more power. That’s a surprise....last question, did you personally experience any issues when testing either of them?
None, I did mount them remotely to keep the heat away, both both are still running strong!
Lock your Hubs 4WDing BEAUTIFUL! I’ve just ordered a 15v one... if you want to possibly fan force one with no extra power...look at a 55w peltier module thermopasted to the front door & wired directly to a 5v electric motor on front door also, with shaft through the door & a metal RV boat prop on the inside.👌🏻 will work as long as the door has heat, closed circuit.
@@pauladams1156 I would like to add a second element firstly, though fan forced would definetly help, especially with stainless trays.
So can you run the oven for 2 hours without damaging the battery with engine off ? 105 amp battery. Is it bad for the battery to drop to 10.5 v ?
Depends on the battery chemistry. Lithium no worries, AGM should be fine if you start with a fully charged battery.
Is there anything different been 12v and 24v travel buddy other then volts
As far as I know it's just the operating voltage.
12v devices have good voltage tolerance. I can't imagine the oven will be damaged.
Mine's still happily running on 15v happily so far.
@@LockyourHubs4WDing i thought so. There arent any electronics inside.
@@cameranmanner4701 nope, just a timer, thermostat and an element basically.
What does the performance look like with a 24V step up?
Smoken! :)
Is the most basic way to use the step up converter , plug it in with Anderson when you need it and then unplug it when you are driving ? I’m not an auto electrician so don’t want to do anything to difficult in terms of wiring..
The units I tested aren't suitable because of their limited input range for driving. Though I notice Sommervile Metal Works sell on that you wouldn't need to disconnect.
can confirm, the 15v reg (even though it says max input 13 volts or whatever it is) still works and is without damage running while a dc to dc charger is charging as well (at 14.6 volts)
@@LockyourHubs4WDing but if I disconnect when I drive and then connect when I pull up to camp or whatever, that is fine ?
@@jackdunn1687 yep, that'll work fine.
Will a step up converter void the oven warranty?
You would have to refer to the individual manufacturers. I know for instance the Big Bertha specifically prohibits the use of step ups. Then in the next breathe specifies a maximum input voltage of 15v......
LOL any excuse to break out the Four & Twenties :)
Absolutely any!
Does the stepups work with the opposite? Which is a fridge
That's a great question, I'm not sure, but I'll look into it.
@@LockyourHubs4WDing thanks
I only cook when driving. So are these useful when driving?
Yes, absolutely especially the 15V version.
@@LockyourHubs4WDing thanks mate. I thought maybe it was only useful when stationary to get up to driving amps .
Just hooked my 80w solar panel it was running at 6a and 83w in the sun. By rights would that be enough to not 100% offset the power draw but sort of help keep some juice in the battery so I am able to run my oven with the vehicle off? I wanna cook dinner without pissin me mates off by runnin a 3 inch straight pipe diesel for 2 hours
That would partially replace the juice the TB was drawing from the battery. If you leave the solar out for longer than you're cooking, you could fully recharge the battery.
@@LockyourHubs4WDing bloody legend mate. I'm buying the step up converter aswell. Gettin the road chef for me 30th in a week. Parmas are my first cook!
@@trentwilliams1176 nice, a parma is my favorite pub grub!
So are the 13.8 v at 10amp is it
The step up specs?
The 13.8 V reg, will be the same as driving, as the car system is a nominal 13.8 to 14.2 volts while driving..
Yes, you might only get a marginal improvement if your charging system is closer to 14.2V.
Where can i get the 13.8v one please
he said "eBay" in the first part of the video.
Yep flea-bay is the answer!
@@LockyourHubs4WDing the 13.8 have different amp ratings does it matter which one i go for
The 13.8V unit I used was an 18A unit, that seemed to work fine.
The oven resistance is fixed.
Power P is Voltage V squared over Resistance R
So increasing V increases P.
Current is V/R.
So increasing V increases current.
Good video.
