Power bank with 12v output

[xstian]

I’m looking for a power bank that has a 12v output, which is rather limiting. It also needs 3x USB outputs with one being a fast charger and one being an input charger. It seems plenty with 2 but not 3 USB. Has anyone seen one?

Not limiting, find a power bank with jump starter. Loads about.

I did look at the jump starters but they don’t have the 3 USB outputs

What about a USB hub aswell?

This does it through usb c, there are probably others on the market too

If your 12v device isn't usb c you may also need something like this:

Sorry didn't read the op properly - only 2 usb ports here too

Thanks, that might just be the job.

Look for power banks with >= 22.5W outputs to get 12v as part of the USB spec. E.g. a 65w powerbank will have 12v. (It will also have 19v which powers most laptops). These will often be 20,000mAh devices, it's less common in 10,000mAh devices.

3 ports isn't hard e.g. my Anker 65w power-bank has 3 including the usb-c cable attached. Look for power banks with usb-c cables attached, to get a "free" port.

If you're trying to run e.g. a router from this, you'll need the USB-C to 12v adapter(s). There are other (better) solutions if this is for 24/7 battery backup of a router.

Probably not quite what you are after but it is a power bank with 3x USB & a 12v output:

My Belkin 20k mah power brick has three USB sockets, Two A and one C.

Don't think it has 12v capability though.

What about a power tool battery inverter thing, they make this for many power tool battery options, also with the option to feed it with more batteries, although this doesn’t do the return feed you wanted.

If you needed to charge a battery by usb feed only then Milwaukee have usb powered chargers for the batteties

Thanks for all the replies.

I need it for a motorcycle which doesn't have a battery. The power bank needs to run a tablet which is on all day so needs to have a fast charger and another usb to run a bluetooth controller. The 12v is for a GPS tracker that needs to have a permanent supply. I have fitted the bike with a 3A usb port which is live only when the bike is running, so I was hoping to charge the power bank when running, which in turn will run everthing else.

I think I should be able to do all this with a USB hub as suggested by Jo-say8k.
