This is for a push-to scope, to power:

 

Two dew heaters,

one phone for Starhopper software

one Svbony SC311 wifi camera

one tablet to connect to the camera,

one utility light.

 

I don't want to rely on internal batteries. The Svbony camera is good for only a few hours. The phone is old.

 

Because it's push-to, the amperage requirements are minimal. Small power packs typically have two, or at most three, Type A usb ports. This setup needs six.

 

Soliciting suggestions that weigh less than the typical camping supply.

Assuming you want a battery, the small USB power banks I've seen generally have 2-4 outputs.  The small stuff I've seen with that many outputs is normally an adapter running off AC.  You can see all these on Amazon as  "USB power bank n ports".

Maybe someone else has seen a small battery with at least 6 ports.

 

Good luck!

My suggestion is to obtain a 12v DC powered industrial USB hub, something like one of these others have suggested.

 

Pick a hub that has port count you need making sure each port can output enough power.

 

Buy a 12v battery possibly a LiFePO4 like one of these and with a 12v connector cable to the hub plug in your USB tech.

 

No need to run a USB 'out' cable unless connecting your tech to a computer.

 

Reasoning is that my old iSound 5-port USB power supply battery never did supply 2.1 amps to all ports at same time and is now bricked waiting for recycle.  It was convenient and I used it a lot yet 6 port units seem tough to find.

All the things powered by USB, but not communicating via USB, won't need to be on a USB hub.

 

There are tons of cigarette lighter multi-output "USB chargers" out there. I would just get one (or two ...) of these. Can easily be replaced or upgraded when needs change. If you run dew heaters and other high drain devices, you'll need something a bit higher capacity than an USB power bank, anyways.
