Not really a lot to say about this device as it is a power supply unit. Basically, it can handle virtually any 9-Volt effects pedal, or connect two outputs together to supply 18 volts (for something like the Fulltone OCD or Plimsoul pedal, where 18 volts can raise the power rails of the op-amps to give more headroom). The Fuel Tank has 5 isolated outputs, these seem to deliver a clean output independent of each other output. I can certainly vouch for the fact that the power is isolated from each output and is consistent. I have only had problems with one pedal so far and that was the Mooer AutoWah and this was down to a problem with that pedal seeming to require a strange voltage and making a hell of a lot of noise. I put that down to a faulty Mooer unit and nothing what so ever to do with the Fuel Tank!To sum up, this is a technically not the most exciting guitar product to buy, but I have been using this now for every gig for the last two years (and rehearsal etc) and it has been totally solid. If you need to power your pedals, I would certainly consider the Fuel Tank!The Fuel Tank Jr is switchable between 115 and 230V, so you can use it worldwide should you need to.Pros

• Compact size
• Bright red LED looks cool!
• Solidly built and very robust

 Cons

• If I had to have one, I wish it has an IEC connection rather than figure of 8, just makes life easier (and don't need to carry extra cables along side the IEC that we have in abundance.
