Battery powering a Phil Jones Double Four
- Thread starter CauliColin
- Start date
My old Lenmar works at 19v, which was the Phil Jones recommended battery when they were still available. The Krisdonia would work.
It's the same as the lithium power tools batteries, listed as 20v, but are really 18v. As well as power amps, some listing with their peak power, when continuous is the real number. I would have no issues at all buying the Krisdonia.

OK, finally drug out the Double Four and battery pack and played with it some yesterday.
All that is on the battery is the markings that it is a G3 K2. I also powered a pre with the 12V output.
A useful note with the Double Four: Add a pre-amp pedal to the input and one can get increased usable (within reason) SPL.

Actually, you need to be careful with this when using a battery, because this is exactly how I get the Double Four to overdraw current from the (PowerAdd) battery and cause everything to shut down. Putting a pedal or preamp in front of the amp and boosting the signal is ultimately going to demand more current from the battery and that is an easy way for me to get my PowerAdd to shut off. I am able to push the Krisdonia harder, but I haven't pushed it to the limit (yet). But plugged into the wall, it can be ok. But this isn't the kind of amp that you want to overdrive too hard.

This looks like a really good option if it supplies the current as advertised. If I had known about it earlier, I might have bought this initially.

Have any of you Poweradd2 people been able to power a 9v pedal (center negative Boss type)? I can't for the life of me figure out if any of those tips work - the cable itself that you use with the PJ is center positive, and the other ones that fit don't seem to do anything. I can't even find an adapter that I could use with this thing.
I tried.. tips didn't work for me...try this, I ordered one but haven't gotten it yet

Please let me know how that works.

I didn't have that problem with the 55,000 mAh pack I used. With the Poweradd, the D4 would shut down with no added pre by trying to turn up the volume just a small amount. I also have the option of using the poweradd to power the distortion pedal, although I have been thinking of making my own 18v power supply for just the pedal, since it is now part of my always-on sound used with all of my amps. The pedal operates from 9v to 18v and has better sound with the higher voltage, although it did fine with the 12v output from the battery pack.

I will say it is almost drastic differential perceived SPL with the D4 by adding a pre.
Actually, they won't work, either. Someone in the questions asked about polarity. These are center positive, so the only option is to cut the wire and rewire the opposite.

Ah, time to cancel my order and get these, thanks!

If anyone got a spare battery and they don't want it/aren't using it...I'd love to snag it from you. I'd like to get a 2nd double 4 for a stereo battery setup to use with my Beebo
I don't know if this is cheaper than usual, but I noticed it's an Amazon Lightning deal for about 4 more hours:

$110.49

I think that's about $10 cheaper than it was a week ago.

Hi all, I've perused this thread attentively as I am using a Poweradd Pilot Pro 2 and also have the problem of it shutting off at full power (which happens when playing outdoors or with a loud band).
I'm considering replacing it with a more suitable model. I've made note of PJB support's recommendation of having 20V at 5A.
I've seen the recommendation for the Krisdonia powerbank (25000 mAh), although it is listed as topping out at 4.7A for 20V. Can anybody confirm it is indeed sufficient for the amp and doesn't black out at full volume?
Also, I read that it didn't fit into the handle, although it seems a bit thicker and narrower than the Poweradd, which makes me think it should fit? Not even with some encouragement?
I also appreciated the power drill solutions, that would be my backup plan but I would prefer something as compact as possible since this is a portable setup and space in the bag is scarce...
Additionally regarding the Krisdonia, would it also power the Zoom B3 over USB at the same time?
Thanks for the feedback!
Cheers

I've been thinking about what I would do if I had to buy the thicker Krisdonia and decided to simply use longer screws and spacers for the handle to fit the battery.
