500 mA per USB portyup thats just a standard DC jack, it wont up your voltage without a mega loss in amps
if USB outputs for example 5 volts at 2.1amps to 12volts your amps will be around 1 amp
On a computer maybe, my USB ports inside my caravan deliver 2.1 amps500 mA per USB port
these work pretty well, its what i buy

i need 6 volts to run a DMX Wireless receiver on my lights at work that already have a USB port, so this little step up is tuned for 5v --> 6vBut 12v psu's are so cheap. Why would you need to step up usb? I just keep all my old psu's and I have quite a few.
Here is a 1A 12v PSU for R95. https://www.communica.co.za/products/psu-swm-12v-1a
I really just want the cable, the electronics lessons at a later stageOk so how do you expect to get 12v out the other end? You would need a step up transformer at least.
Even if you where to step it up, your 900mA is going to drop.
Good luck:I really just want the cable, the electronics lessons at a later stage![]()

ok I just bought off amazon, I will get it Friday
This is probably your answer. Get a 12v7a (an alarm or gate motor battery) , go to any electronics or security store and get a 12v pigtail. Connect the red wire to the + and the black wire to the - and voila you have a 12v backup. Add a 12v charger and you can connect it inline and forget about it.Connect it directly to a car battery.
