Effects pedal board power... IF you can solder!

Effects pedal board power... IF you can solder!
These can make a decent, compact and inexpensive substitute for those $100 rechargeable pedal board power supplies that won't fit under your board anyway!I don't know what most folks would use these for, but I wanted a couple to test for powering (bass) guitar effects pedals so I wouldn't have to haul cords around and try to find extra AC outlets.The voltage is accurate on these but they are the wrong polarity for effects pedals. It's simple enough to cut the cord reverse the wires, and solder back up with shrink tube insulation. You can't even tell. Plus I removed most of the length of cable at the same time, as the most I would need would be 6-8". I also soldered 2 additional plugs on in a "Y" configuration so I power 3 pedals from each one of these. Could have powered 4 or 5 or more (depends on power draw of the particular effect) but I wanted to draw no more than 50% of rated current. 2 of these cables, modified like this and plugged in to an Anker battery pack USB phone charger, which is zip tied under my pedal board, easily powers my entire effects board (of small 9v TIP NEG) pedals and still leave an unused USB port on the power bank for my phone or tablet, or gooseneck usb console light. I can go 2 solid 4 hour performances and still not kill the Anker battery pack. It DOES however take at least a day and a half to recharge the battery bank.*In conclusion, I think they would have a good thing going for the price, by simply 1) reversing the polarity and 2) package with a 3 way splitter or daisy chain with 5.5mm plugs in a tip negative polarity. Oh, and 3 rubber caps to insulate any unused plugs!Edit: since I wrote this, I added another, and powered a newly acquired SpectraDrive and my old Line 6 wireless. Seems solid, but I'd feel better with 4 instead of 3.

So happy and impressed. I bought a new LED Projector from Amazon https://www.amazon.com/gp/product/B07JH74N32/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

This is a 12v projector with an internal battery, but the battery only lasts a little more than an hour, not long enough for a full movie.

I bought this USB to 12v dc adapter to power the projector rather than using the wall plug.

My expectation was that either it would not provide enough amps, or just enough to more slowly drain the projector battery so maybe I could get 90 or 120 minutes out of the projector battery.

To my surprise, this usb adapter not only provided enough energy to power the projector, it also topped off the internal battery charge! Far exceeds my expectations!

I put a USB voltage checker on the input, it was taking between 1.75-1.95A of 5.06V from my usb external battery (the kind you use to charge a phone)

This will make my projector so much more used, as I use it outside on camping and boating trips.

We bought 3 of these. The 1st time we used the 1st one the usb part pushed into the case 5 minutes into a 4 hour road trip. Our 2nd one the case opened after the first use we got it to close but now the usb has completely fallen out(see pic). Our 3rd one the case is starting to open. We have had these is use for 4 days and have used them 2 times. Obviously I'll be returning them and would not recommend these at all.

I have a small Eyoyo 8" monitor that comes with a DC 12V 2.0A wall brick. I had hoped that this cable, when paired with a Konfulon lithium ion power battery of 20,000mAh would power the display, allowing me to go mobile with it.

However I just get flashing monitor boot screen.

Without this step up cable, the lithium ion battery can output 5V/3A, 9V/2A and 12V 1.5A. So I'm disappointed here. At 20,000mAh this is the beefiest pocket battery I've seen.

I tried plugging into my desktop computer's USB 3 port and still got flashing. If this is user error, please advise. Otherwise I'll assume its the cable not being able to provide advertised power.
