Looking for a small cylinder / tube-like pouch bag that opens at the end to hold a USB-Werk charger and wires on/under the bars. Not finding much so maybe some better ideas to be had on here.
Would need to be about 14x 6cm min. It's a compact dynamo to USB device but I'm not convinced the wires leading to the connections are the most durable so putting it on the bars so there's no movement between charged item and the USB-Werk makes sense.
Here's one under the top tube of someone's bike -

Had it hanging from the stem in front of the HT in a small tool pouch with a velcro one-strip, would be neater to have a mini cylinder bag of some sort attaching to the bar either side of the stem.
So far I've looked at too many 'molle' items on ebay, got a bit EDC/SWAT'ed out. Tactical man-bags galore and even a 'tactical headphone pouch'?

"Go Mikes"

Anyway... any ideas for what to get/modify?
(quite like the Restrap tech bag, but it's bigger than I need and I tend to find bags in that stem cell position a bit annoying)
