Sanyo Eneloop Pedal Juice

This is a very cool power supply, I use one along with 2 daisy chains on my pedalboard (see pics) to power 10 pedals!
First off it's rechargeable! So, you just plug into you pedalboard, turn it on & it's powered ready to go, completely ellimulating the possibility of AC ground loop noise simply because it's not plugged into the wall while in use! It can handle 2,000ma, that's a lot of pedals!

Product Description
The SANYO KBC-9V3U Pedal Juice™ is equipped with high-capacity SANYO eneloop rechargeable lithium-ion battery technology which provides stable, long-lasting 9V power for music effects devices. Power to the Pedal! For more than 35 years, SANYO has pushed the envelope in the development of rechargeable battery technology. Today, SANYO is recognized as the leading manufacturer of Li-Ion batteries in the world. SANYO battery products are used for many commercial/industrial applications ranging from automotive, power tools, portable computers and telecommunications. Pedal Juice is built upon this legacy of industry leadership. 

Up to 50 Hours of Continuous, Quiet, Clean, Stable Power – from the First Note to the Last
Stage and studio recording musicians often need to replace the 9V batteries well before they have been exhausted, in order to prevent any disruption during a musical performance. This only results in users having to purchase, and then discard costly, single-use, alkaline batteries. Pedal Juice eliminates those pesky 9V battery replacements. The sound quality also deteriorates when the 9V battery voltage falls below the proper operating range of an effects box. Now, the SANYO Pedal Juice™, KBC-9V3U provides users with up to 50 hours of continuous, quiet, clean, stable power, even as the battery drains. It can be fully recharged in only 3.5 hours using the included AC adaptor. Getting power to effects pedals has never been easier. Power to the Pedal! 

Eliminates AC Ground Loops - So Your Tone Comes Through Loud and Clear
Many effects boxes, graphic equalizers, portable amps, and recorder products operate using a 9-volt DC power source. AC adapters and 9V dry-cell batteries are the typical sources used to power these types of devices. AC power can present problems when used to operate musical electronic products. Musicians must set up their gear near to AC electrical outlets. AC power may inadvertently add electrical noise interference (i.e., AC ground loops, spurious noise, hum, etc.) into be desired signal path. With a 500mA load, a typical AC adapter introduces much more ripple noise into the signal path as compared to the clean power produced by Pedal Juice.
