Power your dashcam from a USB powerbank when parked.
This device fits in line with the 5v power supply to your dashcam, the dashcam will power on and off using the car power as normal (power bank does not need to be fitted).
When car power is removed, the relay will automatically switch over to power the dashcam from the power bank if fitted.
This will allow you to easily film when the car is parked without draining your main car battery.
If used in conjunction with a hardwire system (connection to car battery) this can be used as a backup battery. When the hardwire voltage cut off occurs and recording would normally stop, the relay will switch over to the power bank allowing for continuous recording.
Easy connection using USB type A connectors.

Your a problem solver man!!!! A million thanks to you... Now nothing to worry when we have power interruption in our place!!!!
Thanks again for this adapter I will bought via ebay!
Great!
Really good idea, I already have a inverter in my car that is plugged into the lighter socket, so that only kicks in when engine is on I can then from there run a usb cable to a powerbank that i have for my laptop and hardly ever use so would be interesting to see if the powerbank can last a whole weekend because basicly my dash cam won't go into park mode and will stay on. but i can turn the screen off so that should help.
This is perfect for what I have in mind.
Cool idea , I was thinking of using a 5 pin 12v relay. Ignition on to pin 87 then ignition off via + feed to pin 87a then should work in parking mode (with a voltage adjustable switch to protect car battery)
Hi, your comments sounds very interesting. Have you implemented such a thing by any chance?
If I buy this relay, which power bank would you suggest me to buy? I have cold winters and hot summers where I live in the US and I'm afraid of leaving a lithium battery pack in the car. However, I know there are specific power banks that can withstand extreme weather. Should I get one of those camping power banks that have the 12v usb outlets as well as the 5v?
@lowfinger If the dashcam is hardwired, does your solution include the ACC signal to tell the dashcam to enter into parking mode?
Hello and thanks for the video. I seem to understand that with this model, isn't possible to charge the powerbank with car engine on. Is there a solution, or the only way is to charge the powerbank manually? Thanks.
Can this works with a USB switch? You just have manually switch when you need power from the power bank
Hi I would like to purchase the one where it can charge the power bank when 12V car battery is supplying the dash cam please
Do you have it with type C connectors? if so, I will purchase it
From where you get two to one USB adaptor
Does the connected power bank charge whilst driving or do you need to manually charge it when empty ?
If wired as in the video it is not connected to charge.
As the relay isolates the power bank output it is possible to charge it while the dash cam is on car power with an additional 5v connection to the power bank charge port.
However...
Depending on the model of power bank you use, when the car turns off, the power bank stops charging and the relay switches to power the dash cam from the power bank, some power banks will not detect the load of the camera until a fixed time from the charge stopping so it may not power the camera, if you were to unplug the camera and plug it back in again it would then power from the power bank, on some power banks you can just press the charge indicator button and it will start to output in this condition.
Also if the 5v power supply that is charging the power bank is a different 5v power supply to the one powering the camera this will increase the chance of the switch over working as desired (this is advisable also due to the load the power bank charge and camera would put on a single 5v supply.
Do you recommend a solar power bank using your product? So that way I don't have to worry about charging it often...
Let me know so I'll jump to the link an buy your relay, thanks.
Hi Rafael, a solar charger can only help but will not add very much charge and the power bank would need regular external charging.
Just a Short question - will your Solution work like the Hardware Kit ?
Will the Cam automaticlly Switch to parking Mode when Running via powerbank is it just a Solution for Letting the Cam Running the hole time without killing the battery of the car ?
It can vary by dash cam, it will work like a hardware to keep running the whole time but some camera's can go to parking mode based on other factors such as monitoring location.
@@lowfinger alright thanks for your very fast answer. Ive Order the Viofo a129 Duo so I guess I have to test this. I Hope this will work and the Camera will Switch to parking Mode, I Not I think I Need to Buy the hardware kit but im Not the biggest Fan of using my car battery
@@friedl19981 Hi. Did you ever figure out if this relay works to put the A129 into parking mode?
@@eamonneamonn482 hey, i bought the Adapter but never tested it. I bought the normal hardwirekit because of the low lifetime of a powerbank in a car and the weather we have here in germany. Cold Winter and hot Summer would be the death for every powerbank After a year
will this power a 3 channel dashcam viofo t130 or viofo a139?
The models A139 and T310 both quote 5v 2A so can be used with this relay.
Cool. How did you do this? 🤔 Can it be done with a bigger backup battery...preferably one that is a solar charging backup battery?🤔🙂
The slow charging rate of LiIon means that even with long drives it is hard to keep the battery with enough charge so rotating two high capacity power banks is the best option. This is not as convenient as the dedicated products using fast charging LiFePo4 batteries but this is still much cheaper than those units.
@@lowfinger okay. Thank you. 😊
Do all of these accessories heat resistant. Like over 120 Fahrenheit?
Always follow the instructions for the power bank, for example, Anker quote 'The surrounding temperature when using the battery is recommended at 32°F to 113°F. The battery should not exceed 129°F'
Will this charge power bank if powered from the car?
If wired as in the video it is not connected to charge.
As the relay isolates the power bank output it is possible to charge it while the dash cam is on car power with an additional 5v connection to the power bank charge port.

Does it charge the power bank when the car power is on?
As the relay isolates the powerbank output it is possible to charge the powerbank when the relay has car power. However when the car powers off, the powerbank stops charging and the dashcam is connected to the powerbank output, the powerbank may not enable its output in this circumstance.
Can you mod that to charge the battery while the car is running?
It would require additional circuitry. I did consider this option. It would suit some long driving situations such as delivery or taxi driver. If there is enough interest in this option I may do another version. Cheers.
@@lowfinger just plug it in and it should charge the power bank when the car is on since its not in use?
@@MadSilence the power bank will charge just as you describe, however when the car power is turned off and it stops charging, the power bank will not give power out to the dashcam as it will not detect the load. I have built a version that solves this problem. There are a few downsides, there is a 5 second break in recording, the charging rate of LiIon power banks is quite slow, you have to have a good quality high current 5v supply that is capable of powering the dashcam and charge the powerbank simultaneously. On balance I think it is best to run two power banks in rotation and charge externally. This is still cost effective and flexible against the capable but expensive all in one solutions.
Where did you get that relay, 8 need one
Hi, you can buy it here, www.ebay.co.uk/itm/284182870896
@@lowfinger thx, I actually have c type with car charger cable, relay is both regular usb
@@lowfinger i neeed to find a solution with car charger cable usb C type
Where can I buy this model?

Technically it’s working fine but it’s not fully automatic power bank should also get charged while Dashcam is getting power through car.
it's easy to do by putting a relay together with 5volts for your battery bank to charge your battery bank when the car is on
How does the dash cam go to the parking mode automatically with this method?
I suppose it just can't. Because there needs to be a certain interval after cutting off the engine. I guess dash cam perceives power bank as ignition. Isn't that the case?
Is that relay custom built cause ive never seen anything that small being a relay?
Is somebody able to make this relay with 3 ways, but with the following logic.
1. Car engine on
2. Car battery (when car is of)
3. If car battery is too low, switching to power bank.
Thank you very much
If you use this relay and a hard wire power supply with low voltage cut off it will do exactly what you describe. Cheers.
Thanks!
This is almost what I'm looking for.
I wanted to go a step further !
I need a relay / switch to connect to car power and if off to switch to car battery and if car battery is below X voltage the power bank should be activated.
Any way to get this setup working?
If you use this relay and a hard wire power supply with low voltage cut off it will do exactly what you describe. Cheers.
Thanks for the reply. We already talked via ebay! Have a nice day
