Sanyo Pedal Juice

This is the Sanyo Pedal Juice, which is a rechargeable battery pack intended for guitar effects and music related hardware. The basic idea is to provide a clean stable power source for your pedalboard without having to worry about dead batteries or cumbersome power supplies.

Pedal Juice adapterThe complete system includes a battery pack and a wall adapter (shown here) that is used for recharging. It takes about 3.5 hours to get a full charge on the battery.

The plug on the adapter is a smaller size than the power outputs, which will prevent accidentally connecting it to the wrong jack.

Pedal Juice batteryThe battery pack is almost exactly the same size as a 125B aluminum box used for many booster pedals (4.7" x 2.56" x 1.65").

There are two standard 2.1mm power jacks that provide the 9v pedal power. One good feature is that the battery pack has a button that allows you to power down all of the pedals connected to it without having to unplug them.

The multi-color LED indicator on the battery pack glows green, orange or red, depending on how much life is left in the battery. The capacity of the power pack is specified as 50 hours at 10 ma., or 17 hours at 100 ma. Each power output can provide 2000 ma, which is more than enough for even the most power hungry pedal. It also has a current limit on the outputs which will break the connection if current in excess of the 2A rating is drawn from the power ports.

Another nice feature is that the power pack will automatically shut down after 10 hours, which prevents totally draining the battery should it be left on after use.

The battery is a 3.7v lithium-ion device, which means there must be a step-up regulator inside to get the 9v for the outputs. The voltage output is filtered so that it is clean and free of noise.

The only negatives that I see for this unit are that there are only 2 power outputs, though you could use a daisy-chain cable to provide more connectors, and you cannot use the unit to power pedals while it is charging.

The unit is solid and well made, and though it only has a 1 year warranty, it should last well beyond that time.

I had a couple of problems while using the power supply tonight.

The first problem was with the power switch when I tried to turn it off. It was difficult to actuate and took 6 or 7 presses to finally get the unit to power down.

The other problem was that there was noise when I was using it to power a Line6 Tonecore Space Chorus. It had a definite power related hum going on, but the Tonecore pedals are known to be tough to power. I switched it over to my AMZ Power Supply and the hum went away. I was also running a Tonecore Tremolo on the Sanyo battery and it did not have a noise problem.

Edit: When using the unit again today, and while having the switch problems, it occurred to me that I had read in the manual that you had to hold the switch down to get it to actuate – holding down on the switch for about a second to get it to turn on or off worked properly. RTM. 🙂

Well thought out review. It answered more questions than the manufacturers web site.

Worth it.
I power upwards of ten stompboxes without problems. Sound is new 9volt great. I rarely recharge, and it really does get full up on power in 3.5 hours.

Oh, and by the way…
Pedal Juice is now widely available in BLACK.

I think it’s pretty gorgeous in the new color – but don’t take my word for it; take a look for yourself:

Bought the Sanyo battery pack last spring, have been using it since then with flawless results. Only potential issue is that it has an internal temp cutoff of 104F (presumably to avoid having the LiPo batteries self-destruct under high loads or high temps), I live in and perform in Kalifornia, and sometimes play outdoor festivals where it is 100F (or worse!), I try to keep the pedalboard in the shade but in case it turns off I have a Voodoo Labs Pedal Power 2 power supply as a backup, easy to switch the two main supply busses to the Voodoo supply. But haven;t had to do it so far, thank goodness. I really like the Sanyo battery pack, lasts a long time between charges (I use at least 10 pedals) and have had no issues with the power switch – just have to hold it in to turn on and off is all.

[2907] Dont get it Says: 12:19 am, June 20th, 2012

I don’t see the point of this product. I don’t need my power supply to be wireless when i still have to plug my amp in. It cant be charged while your using it so a button to shut power off doesn’t help as i still have to plug in a charger. Wheres that saving me time? One more thing it still has a switcher so being a battery isn’t providing any cleaner power.

I realize this is an older blog post, but do you think i could power up a 300mA 18vdc vibe pedal by using a y cable?

Thanks. Your work has helped me numerous times in the past.

You cannot combine the outputs to get 18v.
