How to use any USB power bank on Roland Micro and Mobile Cube Guitar Amplifiers - 5v to 9v adapter

Make sure to use battery packs with at least three 18650 batteries or it won't provide enough current to power these amps.

Very clever way of powering it, well done mate.

Very clever way of connecting the guitar, sure

[@villytheplaguedoc1846]

Huh...neat! I just bought a Roland Micro Cube not too long ago and something like this would save me so much money. I wish I had the knowledge to do that sort of thing.

[@crabbypaddy5549]

I bought iGreely USB to DC Cable, DC 5V to DC 9V USB Voltage Step Up Converter Cable, and it came with inside negative so saved me the work of reversing the polarity.

[@crabbypaddy5549]

and paired it with a 40.000 mAh powerbank. 148Wh. That should do the trick never have to worry about enough battery.

You saved me a lot of time and money. Thank you, mister!

Very useful and enlightening information. Thank you.

Will the boss cube street 2 work with this connection system?

[@sebastianmoyano389]

Done! It worked :D Thank you!

[@vestro59]

With the same apply on the fender passport mini guitar amp that’s normally battery powered? Thanks, great video.

[@vestro59]

Thanks for the informative video. Could this also apply on offender passport amplifier that’s battery operated? If so, are their current connections that don’t require switching as per your video? Thanks.

[@sheriffantstrepreneur3865]

Can you make a video to show us how you change the wiring around? Thanks so much

[@sourdee4272]

Do they make a 5v to 9v adapter with the positive and negative already correct for the amp?

[@georgesbahia]

Super bravo. Merci

[@hemantakakati1103]

Are you still playing like this ? Im planning to buy blackstar fly 3 and run it with power bank. But problem is blackstar power adapter is 6.5v. So now i changed my mind i will buy micro cube. But have a feeling this may damage micro cube in the long run. So do you still play like this with powerbank and did it damage any of ur amps ??

[@sunnysgadgetreviews5886]

@Hemanta kakati, Yes. I also use it with my computer's USB port to power when I'm home. At home, we don't need too loud so shouldn't affect much. These are less than a hundred dollars in eBay so even if they die in few years, savings in battery price is more.

@@sunnysgadgetreviews5886 Hi there, thanks for the video. I was about to order the adapter to try this but then saw this message first. Is it possible that this set up would actually hurt the amp's life?

[@sunnysgadgetreviews5886]

@@butchnap Anything is possible. The amp can go bad even with supplied power supply. However, it's almost a year and both my amps are still working good with usb supply. It's an amp, not a person that knows whether it's connected to the wall or a battery. As long as it gets correct voltage and amps, it'll work fine. One thing to mention is, it only works with higher power battery packs like 8400 mah or more with at least three 18650 batteries. I tried using it with a 5600 mah battery pack and it didn't work as it only has two 18650 batteries that don't provide enough current.

[@butchnap]

@@sunnysgadgetreviews5886 Thanks, I ordered a 2-pack of those adapters. I'm going to give it a shot. I appreciate your insight.

[@christiana.solfire]

To anyone who has tried this: how is your amp holding up? Is it still functioning properly?

[@abcalypso1]

I converted to a ''Powerpack -to- Roland Mobile Cube'' using Thomann **Harley Benton Powerpack 24 months ago...works great on any gig or rehearsal...**powerpack still good (39 euros). The **Harley Benton Pack has X2 9v outlets. (1 powers the amp and 1 powers a MOOER mini DI box for bigger gigs or for front of house PA.) If you make a holder for batt. pack and use existing screw holes you can carefully attach and re-charge your powerpack any time. On my 2nd Roland Mobile Cube, I used a generic ''phone'' powerpack + Joyo ''ZGPW" 5v-9v converter (lipstick-size 10 euros) ...this works fine on Roland battery amps. -- IMPORTANT NOTICE -- Not all ''battery-powered'' amplifiers are outer + (plus) inner - (neg). Check symbols before attempting any of the above or ask an electrician to make the cable and check voltage/current-draw etc.

[@dmitrygit3420]

​​@@abcalypso1Hi. Great invention!have you tried turning something like Roland GR or VG with it on ??

[@eduardoparreira182]

Great idea! How long does it last with this 10.000 mah powerbank?

[@sunnysgadgetreviews5886]

Not sure. I don't use it that long to check but should easily last a day.

[@saurock6447]

Do you think it can work with a regular usb to dc cable powered by a 9v powerbank

[@sunnysgadgetreviews5886]

Should work as long as the polarity is correct.

[@sebastianmoyano389]

Hello! This is very usefull, thank you for the explanaition. If I have a positive outside and negative inside cable, like this + ________( . ________- I don't need to do nothing else, right? Just connect it? Thanks again.

[@sunnysgadgetreviews5886]

Yes, if you already have negative inside, it's good to go. Just check and confirm with a multimeter.

[@emon112007]

thanks for the video.. but when i but the roland mobile v up its cut off and turned off

[@kyriakosxanthopoulos3468]

maybe it is because you run with o powerbank that gives low amperage. Try with a "heavy duty" powerbank, I mean with a powerbank designed t, even, quick chaerge a phone.

[@joserp888]

@emon112007 did you solve it? I'm also interested in buying the correct one

[@geroncra]

I checked the Roland Micro Cube GX and it has a DC input from the wall wart of 5.7 vdc and 2 amp. Don't think this will work with the GX.

[@sunnysgadgetreviews5886]

That doesn't make sense. If it uses 6 1.5v batteries, it's total 9v not 5.7v.

[@geroncra]

@@sunnysgadgetreviews5886 Agreed! I figured the label on the transformer was a misprint but I plugged it in and checked. It measured 5.8 vdc. Perhaps it's possible that the GX has a step up inside so that a standard 5.5 USB can be plugged in the DC jack??? Think I'll check with Roland for clarification. Right . . . It just doesn't make sense. I checked the specs in the owners manual and there was no information. I just sent this to Roland/Boss: The PSD 120 power adaptor has an output of 5.7 volts dc 2 amps (I checked it at 5.8 volts). However, 6 batteries at 1.5 vdc equals 9 volts dc. Is there a voltage step up internally on the DC input jack to step the voltage up to 9 volts dc? If I wanted to run the Micro Cube GX on a USB Power pack instead of batteries what voltage do I need to input on the DC input (5.5 or 9 volts) jack???? Slightly confused

[@geroncra]

Roland confirms for the GX the DC input from the transformer (wall wart) is 5.7 vdc. Probably the safest approach would but to run the 9 vdc into the battery terminals from a separate port mounted on the chassis. I'm gonna break mine down and see what's what on the inside. (update after break down) I bought the USB to 9vdc step up so I'll mount 5.5/2.5 port on the chassis and solder it directly to the battery + and - (noting polarity) on the GX. I don't see why you could not plug a standard 5.5 vdc USB into the existing dc port. Caveat: the Cube may have a different voltage input than the Cube GX. Be sure to check.

[@sunnysgadgetreviews5886]

@@geroncra I see. It's hard to get step up for 5.7 v. You can try regular 5v but it may cut off when amp pulls in more amp playing high volume. My mobile cube pulls over 8 amp with microphone. GX doesn't have mic so probably it'll be okay.
