Run out of fuel

Power supply to me is becoming a challenging choice to make. In the meanwhile i bought this Fuel Tank Classic. Ten outputs..that's a lot you can power up a lot of pedals but at a certain point you will run out of mA. Why? because the outputs are not isolated and they share the mA on the first eight and then on the last two (12v) . After half hour it will start to make noise . But the price..is great for what you get,the sizes are pedalboard friendly and the construction material are good.

too little amount of power for the amount of sockets it sports.

only 500 mah for the 9 volt pedals combined.... that's ridiculous. that's basically one fuzz, one reverb and one digital delay lol... The build quality is very sturdy, that's about the only positive thing I have to say about this power supply.
