Using Phone power bank with 9v adapter

[standavismaine]

Hello all,
I use a phone power bank with a USB-to-9v adapter "USB DC 5V to DC 9 Volt USB Power Supply Cable, Max Current 800mAh, Tip Negative Connector, Compatible for Guitar Effects Pedals"" for all my pedals. It works with the Voiceprint just fine. Any problems anyone can see long term in using it? This setup allows me to use pedals with my battery operated PA when I am not near AC power and minimizes set up time at open mics and the like. Does anyone see a problem with this?

If you aren't getting any noise and the output from the pedal to the PA gives you a good path to ground, I don't see why that wouldn't work just fine.
