Energizer Ultimate 9 Volt Batteries, Lithium 9v Battery.
This is the best out there, but at $6-7 a pop, very expensive.
Rechargable 9V here.
This is your best bet for a cheap product that will work, but may not fit your use case. The major gripes, and why I would avoid this product, are that it will take a very long time to charge and will likely not be able to be in use at the same time it is charging (depending on how many pedals you have plugged into it and the draw of each pedal). One thing to consider is the batteries that are in this product. There is no way the battery capacity is actually as high as advertised at this price point. It will probably only offer about 60%-70% of the capacity as advertised. I can guarantee they're using questionable Chinese batteries, which are always estimated to have a much larger capacity than what they actually can deliver. Chinese batteries are also known for drastically losing capacity after a short time in use and can be quite dangerous. You will not be able to power digital effect units alongside standard analog pedals with this device. All of the pedals powered with this supply will be daisy chained, and therefor not isolated, unless you're only using the two outputs offered to power two pedals (but what's the point in that?).
Ultimately, I would advise anyone interested in rechargeable battery power supplies for guitar pedals to just buy some rechargeable 9v batteries, such as the Energizer Ultimate Lithium, and use those for each pedal until a better solution makes it to market. It would be a pain to change all of the 9v batteries in the pedals on your board so frequently, but there really just isn't a good solution offered for this... yet.
