lotmusic Portable Guitar Pedal Power Supply 7 Isolated DC Output, Built-in 3.7V/10000mAh Rechargeable Battery for 9V Guitar Bass Effect Pedals with Short Circuit/overcurrent Protection

I love this item. It's compact and easy to use. It's compatible with all of my guitar pedals. The battery lasts for several hours with 2 pedals in use. The only time I had an issue was when I left it in a cold car for a few hours. Even after fully charged, the cold temperature affects it to reduce the battery life significantly. So, don't leave it in a cold place.

I play ukulele and have a local busking license. I purchased this Lotmusic SPB-02 power supply to use with various pedals and a portable battery powered amp set up. This is a rechargeable power supply and will power the 2 or 3 pedals I use for a couple of hours performance with no problem. I am not sure of how long it will continue to power the pedals but it hasn't fully discharged after 2 hours.The light weight, small size, and quality construction of this little power supply make it ideal for my use. It will even keep my Android tablet charged as I use that to display sheet music PDFs. If someone asks for a specific song I have a library of about 4000 PDFs and using pedals I can match the style of the piece with my ukulele. I use a Roland KC-110 amp, a compression pedal, a looper, and a combi pedal.This power supply is set to 100ma +9v output. That covers the majority of pedals out there. Note that it may not work for boutique pedals that require a different voltage or pedals requiring higher amperage, such as a couple of the Electro Harmonics pedals that require 200ma.I am very pleased with my purchase and how versatile it makes my system. I can now play many genres of music with my ukulele alone!

man, did 't know what to expect w/this but loving it! coming from a pretty wired up/analog background, but the switch to not having to plug in and portability has been amazing. price was incredible, so far noise level is great, and works as promised.

I like the product but the stopped working just before a gig. It was just past warranty so I can't return it. The product worked well when it worked. It was not defective when I got it but stopped working in the middle of practice.

So much to like about it. Met every expectation and more. I liked it so much I bought a 2nd one so that I could split the load.1. Lasts a long time. I left it powering 7 pedals and it lasted around 9 hours. 6 regular pedals and a GT1000Core which uses a lot more power than a regular pedal.2. It powers my GT1000Core just fine even though it says it needs 670 mA.3. Thin. So it fits nicely under my pedalboard. Another battery I got was too thick.4. Charges with a regular USB. Doesn't need a special power supply to lose.

This battery power supply solves the problem of wonky and noisy AC adapters and eliminates the big power cord. It may not power some of the bigger pedals, but all of mine work good.It charges in about an hour for 8-10 hours use, I've never run out.

Only 5 of the 7 power cables workedEvery port works fine. Just vane with 2 dead cables. Would rate 5 star otherwise

Still works fine, powers 3 pedals for 2.5 hours and still has more storage.
