DanelectroBillionaire BAT-1 Battery Billionaire Pedal Power Supply,Black/White

I LOVE this. I don’t like using wall warts, and the best feature allows you to turn on and off the batterybank to keep your pedals attached without draining your 9 volts. I mounted mine to the bottom of a homemade board, and I couldn’t be happier.

This is basically a 9V battery box that holds four 9V batteries with 4 outputs for pedals. Comes with 4 batteries and 4 cables. My only complaint, hence the 4 stars, is that the Danelectro batteries kind of stink. They did not last very long at all. Like I barely got any use out of them. I use this for bench testing and personally would not use it on a pedalboard, but you could. Very solid, full metal design. Just get better batteries.

It quited down all of pedals. The danelectro battery made my overdrive squeal. Switching it to a different type of battery fixed it.

Not isolated. If you test a single pedal with a single battery, you'll have power only from the adjacent jack, as you expect. But once you connect your pedals power and audio cables (just 2 at least) a single battery installed will power all of them. That happens because once you have a battery installed, all outlets receive +9 but no ground. When you interconnect your pedals, each pedal will receive +9 from the power jack (again, even with no battery in adjacent slot) and ground from the audio cable. So, you are isolated from the AC power but not isolated between pedals. Also, all pedals wil share all 4 batteries, so you can't mix batteries types. It's not connecting 4 independent batteries to 4 pedals, it's more like connecting 4 pedals daisy chained to a larger capacity 9v battery.PS: At first I thought it was a defective unit, so I bought a second one from a different batch. It was the same!

At first I was amazed at the vintage feel of this battery bank power supply with a enamal coating on steel. However, this heft just means more weight to lug around with your equipment especially if you use it on a pedal board or in my case I was building a Ghost Portal box with a couple of mini pedals. There really aren't too many options for a portable pedal power supply and this was the least inexpensive. Unfortunately, it doesn't meet the needs of modern demands. It does come with four cheap looking 9V batteries that remind me of old carbon batteries. Those I tossed aside and instead opted to install some rechargeable AmazonBasics to try to save the environment and be more economical. Installing batteries shouldn't take an hour of trying to properly put the batteries into those narrow slots. I'm not sure if it's the fault AmazonBasics batteries or they engineered the battery slots too narrow too accommodate modern style batteries, but I ended up bending up some of the terminals on both batteries and the Danelectro Pedal Power Supply to insert those batteries without any wiggle room to line up the poles. It even scraped off some of the labeling on the AmazonBasics batteries. I would have been better off just purchasing a Joyo rechargable Pedal Power Supply or a TalentCell.

Nice solution for decluttering my pedal board and not relying on a long extension chord.

So far I love it !

At one point I thought this power supply was awesome. Cordless, isolated power to at least 4 pedals for under $40. If you only used a few pedals, you were set, and if you needed more you could buy a second for still less than a T-Rex Fuel-Tank Jr. One downfall I didn't know about was how the power degrades over such a short period of time. Since it's powered on 4 batteries, they must all be outputting at least 9v's. Once they beginning outputting less though, they don't just turn off the pedal. Therefor, their lack of power begins to slowly degrade your tone and you may not realize it's time to change them before it becomes blatantly obvious.I wrote several poor reviews of pedals thinking they sounded weird, or bad, or broken when all along it was this Danelectro Battery Billionaire. I had to backtrack on them all because I didn't realize the batteries had degraded to outputting below 9v's. Final Conclusion: It's a headache to try and keep it stocked with fresh batteries and it isn't obvious when they need replacing making me paranoid of the tone. I legitimately prefer my Donner DP-1 power brick.

Expédition rapide! Colis impeccable

Handy option for powering those effects pedals that don't operate with a 9V battery. Nice to be able to eliminate the nuisance of a power cord. It's sturdy and well designed so you only need to use as many dedicated batteries as effects being used. It's also helpful to have a power switch that prevents power drainage when not being used. Can't vouch for extra quality of the included Danelectro vintage batteries. I intend to use mostly rechargeable batteries.
