Your videos on electrics are just so damn easily explained to understand. You explain everything in a way how to safely achieve something without feeling like you need a 10 year course in electronics to get something simple up and running.
Thankkk you soo much, me and my girlfriend are deciding to join the van life. We are buying and starting it next month! She was scared because she wasn’t sure how to set up the battery, she didn’t even want to do it until I could explain what I learned to her. So thanks for this detailed instructions and for posting it on your blog!
***PLEASE READ*** Due to some comments on this video I wanted to point out this isn't a product review, so I can't say do this or that as it might be different for other products. I have to be very cautious about what I put in my videos to ensure people don't just do as I do and then not understand what it is they are doing. This is also why I removed links to the products featured as I don't want everyone to just buy this inverter thinking it would be perfect for them, it was bought to power a coffee maker and won't be used for anything else. I also want to point out that using an inverter constantly will drain your batteries and, depending on what you are powering, you might need a solar array to balance your daily inverter demands, and if you have lead based batteries this could mean you significantly reduce their lifetime. This video was 12 days in the making, every detail checked and double checked, however, if you want advice or to ask questions about your own system then please ask me and I'll do my best to answer you.
Hi Gadget John on tour, many thanks for your reply its very kind and I understand regarding recommendations, I only ask as I have just bought a 3KW inverter and seen that people earth them to the chassis, just doesn't sound safe as its metal and conductive and in easy contact
THANK YOU John. I was no good at maths at school. I'm listening to you and I KNOW that you are explaining well but my brain refuses to STILL understand. I'm sorry! I need a coffee and another rest before listening to your next video! ☺
Brilliant. I'm a mechanical engineer but never really understand the sparky hurty stuff, Very well explained thank you. I am trying to set up a split charge relay and have a small inverter I probably wont need now.
Great explanation now all I need is to learn about watts, amps and voltage. Thank goodness we are retiring soon. Should have enough time to absorb all of this.
Hi John, Mandy, Coop. Super video and very instructional. You realise when Mandy finds out you're throwing coffee away that you'll be in the dog house...or is that the Coop house? Stay safe guys and keep up the good work.
I'm looking at the same inverter (except for the 110v version) My suggestion would be to take the fuse out and replace it with an in-line Circuit breaker. It's easier to reset a breaker than trying to find a new fuse in case something happens. Cheers from the USA. Awesome Video!
Hi John, love your posts. New to motor homing and am looking into inverters. This has great reviews but as someone else has asked can you confirm that the Krieger models 1100,1500 & 2000W are actually pure sine wave because all the spec sheets etc for these models say they are modified sine wave. There are however excellent reviews out there. Would be great if you could clarify.
Thank you so much for this video I was going to buy an inverter I don't need an inverter now because I am only going to use 12 volts thank you very much for this video
I am so grateful to have found your channel. This explanation was so easy to understand. Very informative and has helped me a lot in making choices for my power needs.
Great explaination, cant say enough on joining batteries as you explained, I made schoolboy error and my batteries were pants till I spotted mistake. I use 4 x6v and make 2 x12v... nice inverter. Cheers
that is absolute genius about the voltage conversion conflict. superb. never thought of it that way. thanks. am doing a van conversion and beyond gas for cooking was gonna look into getting a leisure battery / inverter set up but i may dodge the invert since all the equipment i use will really be low voltage I.T. or SELV. cheers john!
Hi there very well explained and helpful video. I have the same brand inverter but its 1500w. I have a question does the inverter get damaged if stays under no load? Or is there a minimum load that it needs to be on the inverter. My electrician installed the inverter and said do not switch it on if is under no load. Is it a problem if its switched on and there is a small load lets say around 150w. Thanks for the video looking forward for your answer :)
Excellent vid. Very useful for knowing whats required and how. We've just had a 300W one fitted for camera battery charging and chromebook , but will check out the 12v laptop chargers and more importantly I will check out how its all wired to make sure its the correct way round not just the usual way round. Thanks for posting
Oh Ed, I hope you didn’t pay too much. I used usb chargers for all my cameras, including my drone, and my laptop charges off my power bank. If it wasn’t for Mandy’s love of coffee I’d still have the little inverter that never got used.
@@johnmandy No not too much LOL but i've just ordered an official Acer 12v to 19v supply from Power4laptops at Burnley of all places lol. because of your video so many thanks, will be nicely set up for our month long trip to Austria/Germany in May
Nice bit of kit that inverter bud 👌👍, the cheap inverters seem to kill batteries too! Nor do they last ! ( I wouldn't class myself as a heavy user of power ). 3 inverters in 5 years in my old "works van" ( one nearly caught on fire ! ), and 3 batteries later ! X that by 200 engineers if they too had the same problem as me 🤔, Now in my "new works van" and inverter No 4 🙄! Well I haven't bothered using it, I just rely on USB ports now mate. And kept the expensive ( ironically 👋🤪👋) german built split charger ( from the old works van ) for the "Gentlemans lounge bus" 🤫😁👌👍👍👍
So good! Although, I can’t trust anyone who throws coffee away 🤣🤣🤣 I’m glad you explained the battery flow, I’m amazed how many people don’t get that. If you got with three of 4 batteries even that method would still strain the outer batteries slightly more than the inner two. The best solution would be to go back to a positive and negative terminal with same length leads... Great work..
Great and informative video. I am a newbie and have a (perhaps silly) question, if I use a 2000 W converter in my Peugeot Traveller and have the engine running while I brew a coffee or use the Microwave, do I damage the battery or can it cope with the loads for a short periode of time? thank you very much :)
Question, if I wanted to connect a solar cell charger to a double battery setup. Where would I contact the solar charger to on the batteries? (Using your double battery setup)
Is there a reason that you decided on a straight inverter rather than an inverter/charger? Do you already have a standalone charger for your house batteries?
Just getting my head round camper electrics. Can I run a full 12v set up (tv fridge, lighting, Chinese heater) and then just use a separate 240v set up for when on site hook up?
Hi, I,ve been looking at converting my caravan to be electrically self sufficient and I wanted to say that I found your video "Detailed 12v inverter & battery wiring guide" the most informative. I understood everything you said about a dirty sine wave and why it needs to be pure: with a dirty wave you're basically converting a DC signal into a sine wave with out a smoothing circuit. I still have lots of questions like the size of solar panel (s) required to recharge the batteies and how best to fit these to the roof of my van, not to mention working out how much power I would actually use in a typical day. Kind regards Steve
Hi John Am onsite in German ski place and have access to 10amp EHU. System in 2 x 110amp AGM batteries with usable 110 ah. Also connected in 2000w pure sine wave inverter. We are spending the week using 12v except to Nespresso Coffee machine when we turn on inverter remotely the off again after use. The coffee machine ranges between 500 - 1000w when boiler is active for some reason it will start coffee machine but then it turns itself off. We also have aircon on board which I've tested on heat mode and this runs fine, on inverter as a test, for a short while. Can you think of anything I should check that is amiss. Also On our way here it worked fine when we switched it (inverter) on and brewed a coffee? It's got me thinking? Cheers Chris
I’d use the ehu and not your inverter if you’re on site, your batteries might be low or battery charger not up to the job to supply high amps so the inverter is shutting off due to low power. 👍🏼
Hi John Thank you ever do much for your reply. We have Victron Blue Smart IP22 Acculader 12/30 (1)charger and BM712 FYI - I think what you are saying is that if our batteries are not near full charge they won't support my 2000w inverter. JANETTE who like your better half loves her coffee as do I and we are running tests for our off grid adventures. I really like the way you and Greg have teamed to give an all round package of assistance to us novices. So coffee availability in the future with our off grid is very important. Our next step is installing B to B and then Solar to complete our package. So thanks once again for your input. Cheers Chris & Family
Link all negs and pos terminals. Then put all pos loads at one end of the battery and all negs on the opposite end of all linked batteries, so the flow of power has to go through all batteries. 👍🏼
Don't have much knowledge on this topic so a question for anyone that knows more than me...I've only had space for a 90ah auxiliary battery on my small camper. What size inverter do you recommend and what size appliances I could connect to that battery/inverter combo?
Hi John, another good video thank you. At 03:43 you should a 12v adapter that has variable power outputs....what is it called please? All of my searches so far give me similar things with a mains plug but I need the type you show with a 12v plug! Many thanks
Hi John, just found this video and found it very helpful, my question is I’m wanting a inverter in my work van to run a small kettle, toasty maker and maybe a travel microwave, also makita batteries to charge, am I ok to connect inverter to my battery as this will only be used on jobs with no electricity, thanks.
Hi John, Thanks for the film, it was great by the way. I'm a little confused as I think you mention that pure sine wave is the better way to go & that's the way you went. Looking at the product it seems to suggest that it isn't a pure sine wave inverter?
Hi John. A big thanks for being available for us. You have a genuine way with you when presenting your material. I have a question I’m hoping you can help me with. The big thing for us, in the motorhome is not a coffee machine lol, but being able to have constant use of two laptops for creative and business purposes. I’m having difficulty in finding a suitable 12v adapter that can fully charge laptops while using. As a result I thought the only way forward is an inverter. However I thought you might help. The laptops are Dell XPS 15 7590 and seem to have a special way of charging. Any suggestions please?
Nice explanation. I have a van use it for work. I need 1 small fridge 700 w microwave I need 2000w inverter and 1X12v around 100 amp Question Can I charge it thro my vans alternator? And it’s not bad for my alternator and so on? Q2, if I leave the fridge on all night while I’m home and not using the car dose it not drain my car battery? I mean if my external battery drain dose my car’s one drain to? Thanks
If you follow this guide you will be able to work out how many AH your battery will need to be etc. Remember 12v amps are much higher than mains power amps. So a 100AH battery alone is not going to power a 2KW inverter if you use the full 2KW power. You should get a DC to DC charger so your van will charge your house battery when the van engine runs. A small 12v compressor fridge will be ok to be left switched on all the time, as long as you are charging your battery often through driving or solar.
Hi John, could you tell me what size fuse I should install between my batteries and my 2000watt inverter. I keep getting different answers. Thank you in advance.
Using the ohms law calculation of volts, watts and amps from this video you can work out what fuse to use. 12v and 2000watts means ??? Amps 👍🏼 In the video I show you how to work this out
Can you advise on a good quality inverter 500w is ok I think? I just need to be able to charge up my bluetti the small one I think it's around 250watt hour capacity. Cheers David
Hi, John just watch this blog I have the exact setup as you ie batt,solar panel, victron controller. On your recommendations. I’m interested in this inverter But the blurb on amazon says its a Modified sine wave ?
Great video but i have questions still. Im fitting out my mates race van and we trying to decide when to use a inverter and when to use 12v to power up his stuff ie microwave kettle toaster phone laptop etc. I've tryied to work out what drains a battery quicker 12v or 240v via a inverter but finding mixed info on the web.
12v is more efficient to power devices. You’ll need an inverter for kettle, toaster & microwave but that’s taken from your 12v batteries. You’re far better off using gas to boil a kettle and toast things 👍🏼
Hi John, we have a 1200 watt inverter, can we simply swap it out for a larger one ??? We have 2 lithium batteries and lots of solar so I guess it’s ok, but not 100% sure. Many thanks
hi great video , ive purchased a 2000w peark power inverter but what size fuse do i need for the connection to the 12v battery and how to work it out ?
hi john the Sterling Power BB1230 12v 30amp DC DC charger what settings do you have it on I'm looking for a set up same as yours I'm not very good on this stuf i have the same camper as you I've looked on you tube and they say they is 3 difrent settings any help would be great john cheers keep up the good work
Great video and very informative!! Id appreciate your opinion & advice please on a Emergency power supply direction im thing of going!! So recently storm Eowyn left left us with out power for a number of days!! I am lucky enough to have a large stove to heat our sitting room with back boiler and produce hot water we do have a dubble camping gas stove and bottled gas for cooking but what i would like to do is produce power and charge items like phones , kids tablets , camping lightes etc! Maybe even just to power the freezer for an hour or so each day to keep it cold! Im very much considering the inverter for my citroen berlingo over a generator. Nothing agenst gennys but we both drive diesels and the local forecourts closed with out power so no petrol and i cant keep a drum on hand just in case! With leads me to thinking a 2000w inverter may be the way to go! There a lot cheaper to buy and dont need maintenance when left up! Im sure the van is capable of providing enough charge to the battery to keep the inverter and the few electrical items going on idling? Sorry for long message but is there any consideration i should take in to accout before splashing out on decent inverter model! Thanks agen for video and opinion on my taught much appreciated 👏
Hi John and mandy I know this is a old video. I used the link to below and ordered the invertor from amazon. It arrived today but they have sent an amercan version . I . Contacted amazon who says they will only be able give me my money back if i return. It to them. . Do you have any ideas where I can purchase a UK version to run my ps4 in my van . Cheers
Does it state UK 3 pin on your order? If so then under UK law you can get it replaced for free, if you made a mistake & ordered the wrong version then are you sure you bought the USA version? They sell a euro version but amazon UK doesn’t sell the USA version. So if you have the euro version then just buy euro to 3 adaptors.
@@johnmandy I went to the link then I went to make and uk version . However they sent the euro version . I did ask for uk version . They lady said they will refund it but now I don't know how to go about getting a uk version . I understand about the plugs but concerned about the voltage as I want to use my ps4 and dont want to damage it . Thank you for your advice . I will just return for a refund for now.
Thank you!!! for this. I’m new to van life and it drives me crazy watching everyone go crazy over inverters and AC outlets. EVERYTHING (almost) in your van life is 12V: your camera batteries, cellphones, laptops, drones, refrigerator, heating system, cooling system, TV, DVD. EVERYTHING. Probably the only exception is toaster or coffee maker. That’s it. Also, the max AC power appliance you can buy is about 1500 watts. 2000 watt inverter is more than enough for your one (maybe two) occasion use AC appliances.
Hmmm my Li-ion battery charger for my Milwaukee power tools needs a 110v outlet so I can make repairs on the road. Hard to repair using a slice of toast while drinking coffee!!
Hi John, a great video. I'm looking at installing an inverter in my motorhome. If you install it near the battery (and out of the way) what's the best way to plug the device into the inverter? Ie Can you use extension lead to get to other side of the motorhome? Cheers
Your videos on electrics are just so damn easily explained to understand. You explain everything in a way how to safely achieve something without feeling like you need a 10 year course in electronics to get something simple up and running.
came for the accent, stayed for the very useful info. thank you for the help & for the great organization w/the timecodes!
That was a GREAT analogy about the inverter re: getting the milk. Great video too.
Thankkk you soo much, me and my girlfriend are deciding to join the van life. We are buying and starting it next month! She was scared because she wasn’t sure how to set up the battery, she didn’t even want to do it until I could explain what I learned to her. So thanks for this detailed instructions and for posting it on your blog!
That’s it, it’s official... you and Mandy are my van gurus. 😍 😄 You explain things so clearly - wonderful, thank you!

Hi Gadget John on tour, many thanks for your reply its very kind and I understand regarding recommendations, I only ask as I have just bought a 3KW inverter and seen that people earth them to the chassis, just doesn't sound safe as its metal and conductive and in easy contact
I agree, but in truth the earth would be via the negative of your battery bank which in turn should be connected to your vehicle chassis.
Just used this guide for reference & successfully fitted my inverter. Microwave working & able to charge laptop too. Thanks John.
THANK YOU John. I was no good at maths at school. I'm listening to you and I KNOW that you are explaining well but my brain refuses to STILL understand. I'm sorry! I need a coffee and another rest before listening to your next video! ☺
John this video is spot on. Thanks. So glad I watched it, I was about to push my car up the shops to get some milk. Life saver 👍👍👍
Brilliant. I'm a mechanical engineer but never really understand the sparky hurty stuff, Very well explained thank you. I am trying to set up a split charge relay and have a small inverter I probably wont need now.
I am such a noob when it comes to electrics but your video was great! Very informative and well explained! Thanks, hope your wife enjoys the coffee!
I had so many questions and you answered many of them, one after another, in this video. Thank you.
Absolutely brilliant explanation! Thank you.... now, do you fancy fitting one for me please?? Lol!
Great explanation now all I need is to learn about watts, amps and voltage. Thank goodness we are retiring soon. Should have enough time to absorb all of this.

As electricity flows it means all batteries share the same load when wire this way. 2 batteries or 200 batteries, the principle is identical.
wow! first time watching this dude. his video is so simple and clear. a really good one!
Great and informative video. I am a newbie and have a (perhaps silly) question, if I use a 2000 W converter in my Peugeot Traveller and have the engine running while I brew a coffee or use the Microwave, do I damage the battery or can it cope with the loads for a short periode of time?

Clear and concise, great video fella.
Question, if I wanted to connect a solar cell charger to a double battery setup. Where would I contact the solar charger to on the batteries? (Using your double battery setup)
Feel free to watch my recent advanced 12v wiring setup video which covers this and more
Is there a reason that you decided on a straight inverter rather than an inverter/charger? Do you already have a standalone charger for your house batteries?
Yes, cost was a factor and separate devices provides greater resilience
Just getting my head round camper electrics. Can I run a full 12v set up (tv fridge, lighting, Chinese heater) and then just use a separate 240v set up for when on site hook up?
Check out my videos, I’ve got a fully wiring guide video.
Kevin James yes you can
Super helpful, thank you!

Hi John / Mandy.....Can you tell me who was your supplier in the UK for this Inverter.....All I can find is modified units. James
Please check my recent tech Tuesday power video.
Great video. One reason why I invert 12v to 230v to charge my Samsung phone is because it charges a lot faster then just off the dc.
Hi, does this use power even with the power off button is activated
Yes, any inverter will consume a small amount of power as it’s on standby.
@@johnmandy thankyou for your quick response, looks like I'll buy an additional isolation switch to prevent this :)
I’ve watch it again and again and now realise you are right sorry massive brain fart 💨 great vid thanks for the help 👍🏼🏴
How would you rate those batteries, have they got a long life span, how many cycles have they. Thanks.
I replaced them for lithium, and then replaced those with agm. Find a battery that suits your needs is my advice.
We are looking forward to our proper coffee from Mandy's Mobile Coffee House at Camp Gadget.
Great info as per, thanks John
I'll need to rethink my solar setup if she starts making 20 coffees a day 😆

Hi John. A big thanks for being available for us. You have a genuine way with you when presenting your material.
I have a question I’m hoping you can help me with.
The big thing for us, in the motorhome is not a coffee machine lol, but being able to have constant use of two laptops for creative and business purposes. I’m having difficulty in finding a suitable 12v adapter that can fully charge laptops while using. As a result I thought the only way forward is an inverter. However I thought you might help. The laptops are Dell XPS 15 7590 and seem to have a special way of charging. Any suggestions please?
Every laptop can be charged from 12v, just type in “dell xps 15 7590 12v charger” into google & you’ll see a few.
Great video, new to this.going to the blog next.
Nice explanation.
I have a van use it for work.
I need 1 small fridge
700 w microwave
I need 2000w inverter and
1X12v around 100 amp
Question
Can I charge it thro my vans alternator? And it’s not bad for my alternator and so on?
Q2, if I leave the fridge on all night while I’m home and not using the car dose it not drain my car battery? I mean if my external battery drain dose my car’s one drain to?
Thanks
If you follow this guide you will be able to work out how many AH your battery will need to be etc. Remember 12v amps are much higher than mains power amps. So a 100AH battery alone is not going to power a 2KW inverter if you use the full 2KW power.
You should get a DC to DC charger so your van will charge your house battery when the van engine runs.
A small 12v compressor fridge will be ok to be left switched on all the time, as long as you are charging your battery often through driving or solar.
Hi John, could you tell me what size fuse I should install between my batteries and my 2000watt inverter. I keep getting different answers. Thank you in advance.
Using the ohms law calculation of volts, watts and amps from this video you can work out what fuse to use. 12v and 2000watts means ??? Amps 👍🏼 In the video I show you how to work this out
Can you advise on a good quality inverter 500w is ok I think? I just need to be able to charge up my bluetti the small one I think it's around 250watt hour capacity.
Cheers
David
Hi, John just watch this blog I have the exact setup as you ie batt,solar panel, victron controller. On your recommendations.
I’m interested in this inverter But the blurb on amazon says its a Modified sine wave ?
I think it links to all their inverters and you choose the model you want, the pure sine wave model seems to be out of stock so doesn’t show up.
I'm very grateful to you for putting this together. Well explained!
Great video but i have questions still. Im fitting out my mates race van and we trying to decide when to use a inverter and when to use 12v to power up his stuff ie microwave kettle toaster phone laptop etc. I've tryied to work out what drains a battery quicker 12v or 240v via a inverter but finding mixed info on the web.
12v is more efficient to power devices. You’ll need an inverter for kettle, toaster & microwave but that’s taken from your 12v batteries. You’re far better off using gas to boil a kettle and toast things 👍🏼
Great explanations. I'll reading your blog.
Hi John, we have a 1200 watt inverter, can we simply swap it out for a larger one ??? We have 2 lithium batteries and lots of solar so I guess it’s ok, but not 100% sure. Many thanks
hi great video , ive purchased a 2000w peark power inverter but what size fuse do i need for the connection to the 12v battery and how to work it out ?
Watch the video as I go through this exact question 👍🏼
@@johnmandy all depends on what i will be using then i think , ?
Great vid!, you’ve just saved me a bomb!…. 12v here we go!!
Very informative - great video!
Thank you very much.
hi john the Sterling Power BB1230 12v 30amp DC DC charger what settings do you have it on I'm looking for a set up same as yours I'm not very good on this stuf i have the same camper as you I've looked on you tube and they say they is 3 difrent settings any help would be great john cheers keep up the good work
Great video and very informative!!
Id appreciate your opinion & advice please on a Emergency power supply direction im thing of going!!
So recently storm Eowyn left left us with out power for a number of days!! I am lucky enough to have a large stove to heat our sitting room with back boiler and produce hot water we do have a dubble camping gas stove and bottled gas for cooking but what i would like to do is produce power and charge items like phones , kids tablets , camping lightes etc!
Maybe even just to power the freezer for an hour or so each day to keep it cold!
Im very much considering the inverter for my citroen berlingo over a generator.
Nothing agenst gennys but we both drive diesels and the local forecourts closed with out power so no petrol and i cant keep a drum on hand just in case!
With leads me to thinking a 2000w inverter may be the way to go! There a lot cheaper to buy and dont need maintenance when left up!
Im sure the van is capable of providing enough charge to the battery to keep the inverter and the few electrical items going on idling?
Sorry for long message but is there any consideration i should take in to accout before splashing out on decent inverter model!
Thanks agen for video and opinion on my taught much appreciated 👏
Hi John and mandy I know this is a old video. I used the link to below and ordered the invertor from amazon. It arrived today but they have sent an amercan version . I . Contacted amazon who says they will only be able give me my money back if i return. It to them. . Do you have any ideas where I can purchase a UK version to run my ps4 in my van . Cheers
Does it state UK 3 pin on your order? If so then under UK law you can get it replaced for free, if you made a mistake & ordered the wrong version then are you sure you bought the USA version? They sell a euro version but amazon UK doesn’t sell the USA version.
So if you have the euro version then just buy euro to 3 adaptors.
@@johnmandy I went to the link then I went to make and uk version . However they sent the euro version . I did ask for uk version . They lady said they will refund it but now I don't know how to go about getting a uk version . I understand about the plugs but concerned about the voltage as I want to use my ps4 and dont want to damage it . Thank you for your advice . I will just return for a refund for now.
UK & Europe use 220v to 230v so it's going to work perfectly fine.
Really useful and clear explanation, thanks!
Thank you!!! for this. I’m new to van life and it drives me crazy watching everyone go crazy over inverters and AC outlets. EVERYTHING (almost) in your van life is 12V: your camera batteries, cellphones, laptops, drones, refrigerator, heating system, cooling system, TV, DVD. EVERYTHING. Probably the only exception is toaster or coffee maker. That’s it. Also, the max AC power appliance you can buy is about 1500 watts. 2000 watt inverter is more than enough for your one (maybe two) occasion use AC appliances.
Hmmm my Li-ion battery charger for my Milwaukee power tools needs a 110v outlet so I can make repairs on the road. Hard to repair using a slice of toast while drinking coffee!!
Cracking video, just about to get one and this answers all my questions , funny seeing past John hairless lol 😂
Great video. Could you tell me what inverter you used please?
As with every video I make there are links in the video description to products featured in my videos.
Informative video John - many thanks 😊
Well done John, great video! Very meticulous! Thanks a lot for all this!
Great video so many useful little tips thanks
Hi John, a great video. I'm looking at installing an inverter in my motorhome. If you install it near the battery (and out of the way) what's the best way to plug the device into the inverter? Ie Can you use extension lead to get to other side of the motorhome? Cheers
Yes, that’s fine 👍🏼
