New "take" on power supplies, Sanyo Pedal Juice Rechargeable:

[scotch]

Can't say that I'm really impressed, but someone may find utility in the Sanyo eneloop.

Ha let me explain why this is awesome.

I use an X2 wireless soon I will have 3 of these, 2 for switching basses and 1 as a backup (someone gave it me in place of money they owed)

If I use this and 2 X2 wireless's I could have a totally clean wireless board, X2 Receiver (ch1) to turbo tuner, to super nova drive to sft to X2 transmitter (ch3)

I know silly right, still gonna do it.

Now to find the price

*Found Price* May hold off on the 200usd price tag for a bit

But either way my theory is sound and completely useful

[Mark Latimour]

Not a bad idea. It has a lot of current which is good and it would make sense on small stages where extra cabling can be a risk.

[TheWoodShed]

Two outputs at 2000 mA each...I bet you can run an 18v pedal using the right cable.

No 2 outputs 1000ma each

Would make setting up so much quicker

[Bryan R. Tyler]

This in combination with a wireless MIDI system could mean having a completely remote MIDI controller board. Very cool other than the price.

At some venues getting a power supply for your pedals can be a pain in the ass. For instance, I'm still trying to work out with the venue how many power plugs I'll get for a performance this weekend. Some stage managers can be quite problematic. This would solve a lot of problems! Now, if only they had one for PA and amps that was smaller than a full blown generator......

i saw these sometime back.

it cannot be used (give out power) while it's charging, written in the manual, so just make sure there's enough juice in there before using. - charge it up the night before you use it, or buy many and have one fully charged at all times if you're a heavy user.

also the high price is a bit of a letdown, because i would imagine if you open it up, you'll just see groups of AA rechargeable eneloop batteries in there put in a configuration to give out the right voltage and the right mAH. - which together does not make up that price they are charging for it. (but of course, this is my own speculation without having the experience of taking this apart)

[Darkglass]

if it actually gives up to 2A of current, you would need hundreads, of batteries.
If it´s a lithium battery, is probably quite similar to the ones used in most laptops.
I didn't if it lasts over 50 hours with a 2A consumption (100AH), that, would be very impressive.

[Marill]

this is the approx usage from the website:

Analog effects unit (Distortion, Overdrive, etc.) - Current used about 10 mA: Approx. 50 hrs.

Digital effects unit (Digital Delay, Digital Reverb, etc.) - Current used about 50 mA: Approx. 27 hrs.

Multitrack recorder or synthesizer - Current used about 300 mA: Approx. 7 hours

Electronic drums or percussion - Current used about 1,000 mA: Approx. 2 hours

Three effects units (Overdrive, Chorus, Digital Delay) - Current used about 80 mA: Approx. 20 hours

take for example, the current draw for electronic drum - 1000mA, they give lifetime of 2 hours.

so from that, total current draw over the 2 hours before it runs out of juice is 2000mA.

or the first entry, where an analog effect drawing 10mA can be powered for 50 hours, so the total current draw before it runs out of juice is 500mA for this case

a single rechargeable AA battery capacity is usually rated about 1800 to 2500 mAh, (and i think sanyo eneloop AA rechargeable is rated at 2000mAh)

so you don't really need hundreds of batteries to provide that current, you just need enough AA batteries to make up the voltage.

[TaySte_2000]

Starting to wonder if I could make one, I wonder what a single rechargable pp3 is capable of

[Darkglass]

Ok, didn't read the current charts... I stand corrected .

[Marill]

darkglass, i read the website a little bit more too, and you're right about them using lithium-ion batteries, it's stated in the overview, so that's probably why they are charging higher price for it, because lithium ion batteries are generally more expensive.

initially i was assuming they used regular sanyo eneloop AA NiMH rechargeables, and if they were using that, it totally does not justify the price.

a single rechargeable pp3 will not have much capacity, probably around 280 mAh (i remember this is the energizer rechargeable pp3 capacity), while a non-rechargeable one is about 600mAh.

that's one reason why you don't see many rechargeable pp3 around - they are just not worth the price and trouble for the low capacity, as compared to a non-rechargeable. i say trouble because for a rechargeable, even if you don't use it, it will lose its charge at quite a quick rate, as compared to a non-rechargeable, so if you leave one in your pedal (or just on the shelf, not in any pedal) for some weeks without using, when you next use the pedal, it may already have low charge left in there.

"eneloop" technology is supposed to address this issue of quick discharge even when not in use. so they claim for a fully charged eneloop battery, even after 6 months of not using, instead of finding your battery dead, it would still have about 80% of the charge left.

[TaySte_2000]

I suppose another arguement is that is list price, if they get them into musicians friend discounted to $100-$150 then would be easier to give it ago.

[KarateKid25]

You could make one, but by the time you get a decent battery to match the eneloop's one, a case, cables and a proper balance charger (because it's a lithium based cell), you'll not be very far in front. I can't find the page now, but I saw them announced somewhere a while ago stating that the street price would be about $110, from memory.

Don't quote me on that though!

Street price of $110 and I'll have one of them for sure.

Wireless pedalboard here I come

[KarateKid25]

Also, I just had another look at the specs page and noticed it says:

Two DC 9V ports (max. output 2,000 mA *2)

I read that as 2000mA times two, not divided by two. I would take that as being 2000mA per port. It's not very clear though...

[KarateKid25]

Oops.. Brain fart.

That means 'read note 2' not times two

1000mA it is
