Q: The spec says a Max Current of 300mA. I want to use it for BOSS MT-2 pedal which requires 200mA@9V DC. Can this be used?

They've updated the product at least once now, it seems. I have three I've bought from Amazon with 2013 copyright logos on the bottom, that have "Regulated" printed above the large "ADAPTOR" verbiage, have a 300mA rating, and are a larger cube shape and are much heavier. The revised version drops the 'regulated' verbiage on the box front, has a 2018 copyright, has a 500mA rating, is a rectangular shape like in the current Amazon photo as of 2020, and is MUCH lighter in weight. Both have the exact same model number PW-CT-9V, and UPC code 0 19954 95097 2.

Q: I've purchased 3 of the 9volt Planet Wave Adapters for my Fender Mini Twin Reverb Amps. When I plug them in, I only get a humming noise. Troy,txs

That not a question, but I'll turn it into one and try and answer that question that I just wrote. "Why do I get a humming noise when I plug my planet waves adaptor into a mini twin fender amp?"First off, does your mini twin work with a nine volt battery? Check that. If not, then the amp's broken. If yes, continue. I just checked, and the mini twin seems to be center negative, like the adaptor. Still, check to see if your mini-twin power in is expecting a center negative power supply.Perhaps the power supply input jack on the mini twin is broken?Perhaps you've gotten three bad power supplies. Have you checked them with a multimeter?Good Luck.

Q: If I have a splitter, how many pedals max should be plugged into one power supply?

Hey got to your question late, but I agree with AJ Rugged's answer. The Planet waves 9V power adapter is designed for use with one device with a power draw of no more than 300mA. I do not recommend using a splitter for this power adapter, or any single adapter for that matter. Shop around for a power supply that will power the number of devices you will be using safely. Perhaps here on Amazon? Be safe and good luck.

Q: Does this power supply work for my dymo label manager 160? it calls for 9v 2a.

Absolutely not. 2 Amps is 2000 mA, this supply is rated for 500 mA so it can only supply 25% of the current your device needs.
