Hi Guys,
Thanks a lot for your help and suggestions, you are helping a lot! I am still thinking about it and the motorcycle battery is tempting me, apparently I could even go for a gel battery and put it under a seat. Such as something like this:
https://www.amazon.co.uk/gp/B00LFMP89K
How about a set up like this:
1. Plug a Y splitter on the cigarette lighter
2. On one of the 2 plugs, link to the battery to charge it. On the other plug, link to a the cameras directly
3. Add cables between the battery and the cameras, with a switch and a 12v to 5v converter in the middle.
As a result:
When the car drives (ignition on), the battery charges and the cameras are operating (I could even remove the batteries in the mobius)
When the car is parked the ignition is off so no current going out of the cigarette lighter, hower I can activate the switch and the gel battery would power the cameras.
What do you think? Any risk doing so?
Long term I can weld the cables directly on the 12v somewhere in the car to make it clean and stealth.
Thanks for your feedback!
Despite the claims from certain producers of power banks that their products can handle it (pass-through charging), they should not be charged while they are under a load.
In addition, leaving a power bank in your vehicle at all times is a bad idea because lithium-ions batteries should NOT be charged or left for too long in a hot vehicle during the summer and they should NOT be charged when they are stored in sub-freezing temperatures.
Cards on the table, I know next to nothing about battery technology. However, I would note that the Cellink B is advertised as only re-charging once the battery has been discharged (unlike the T-Power). Also, lithium-phosphate batteries are said to be stable at very high temperatures?

Why quote me saying that, "leaving a power bank in your vehicle at all times is a bad idea because lithium-ion batteries should NOT be charged or left for too long in a hot vehicle" and then go into a spiel about alternative chemistry LiFePO4 batteries being stable at very high temperatures? I even went on to mention in my post that there are indeed some "expensive solutions on the market" (like the Cellink) , pass through charging should be avoided with most power banks on the market.
My entire post was in reference to the standard lithium-ion battery banks such as the OP appeared to be initially considering when he said, "Any comment or advise on this?"
So, now that you've got your "Cards on the table", what point are you attempting to make here?
Bejesus, where did all that come from fella? I was simply noting a couple of things should others not be aware or hadn't fully digested your very knowledgeable post.
Hi All;
I currently have 2 dash cams in my car, one at the front (transcend drive pro 220) and one at the rear (transcend drive pro 100). I am about to add 2 mobius on the sides and a power bank to keep the 4 cameras for a few hours (with a switch).
The power bank will have a "pass-through" feature, so that it can charge and still give energy to the 4 cameras at the same time. Once the ignition is off, the power bank will still be able to keep the 4 cameras running (I will have a switch to keep it on only when I want, on a car park for example).
Here is what I was thinking of doing:
My concern is that the usb hub will not relay enough power via each port to keep each camera running. I noticed that usb hubs can be powered with a plug into the wall to make sure it has enough but I won't be able to do this here.
Any comment or advise on this? I would like to avoid silly mistake so I am seeking for your expertise.
Many Thanks!
