If there's even a faint need for a recharging solution, there's a decent shot that Sanyo will have an Eneloop device to fit the situation. Take the newly announced music booster, for instance, which is designed to sit alongside your Tube Screamer, TU-2 Chromatic Tuner and RV600 Reverb Machine in order to keep the juice flowin' even if a breaker trips mid-solo. Truthfully, the device could be used to energize pretty much anything that taps into a 9V power source, and if you're concerned over noise interference, Sanyo assures us that you shouldn't be. The unit -- which goes on sale in March 2010 -- can be fully regenerated in around 3.5 hours, and depending on the drain of the device(s) it's powering, can keep things going for anywhere between 2 and 50 hours. Rock on, as they say.
