Detail 01
2.5W + 2.5W into two 4-inch speakers
Real stereo, so chorus and delay spread across the pair. Volume suits a room, not a stage.

RolandMobile Cube Battery-Powered Stereo Guitar Combo Amp Black
1/3
Independent shopping perspective
The Korena take
Battery-powered 5W stereo combo with a mic channel and amp models. For busking, practice away from power, and small acoustic or keyboard gigs.
Strong match
Who this is for
- Street playing or park sessions with no outlet nearby
- Singer-guitarist who needs one input for mic, one for guitar
- Practicing quietly in a dorm, hotel, or shared apartment
Consider the trade-offs
When to look elsewhere
- Band rehearsal — 2.5W per side loses to a drummer
- Players wanting deep amp voicing control beyond a single tone knob
- Anyone needing a footswitchable or effects-loop rig
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Runs on six AA batteries or an AC adaptor
Works with no wall power at all. Batteries are the default supply here; the adaptor is a separate purchase.
Detail 03
Separate mic channel with its own volume
Vocals and guitar stay independently balanced instead of fighting over one level knob.
Detail 04
Channel TYPE switch plus chorus
Switches voicing between guitar, keyboard, and instrument sources rather than tweaking EQ to fake it.
Detail 05
AUX in with center cancel
Pulls centered vocals out of a backing track, so you can play or sing along to songs from a phone.
Detail 06
2.5 kg, 11 inches wide
Carry it one-handed with the included strap. Fits in a backpack or bike basket.
Final check
Know before you order
- 01AC adaptor is not included — budget for a PSB-120 or regional equivalent
- 02Six AA batteries ship with it; plan on rechargeables for regular busking
- 03No dedicated speaker out or line out for recording or PA feed
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01How long does it run on batteries?
It draws 175 mA at 9V from six AAs. Runtime depends on cell capacity and how loud you play — alkalines get through a typical busking set, rechargeables make it repeatable.
02Can I plug a microphone in?
Yes. There's a dedicated mic channel with a 1/4-inch input and its own volume knob, so you can sing and play at once.
03Is it loud enough to play outside?
For solo acoustic or vocal work on a quiet street, yes. It won't cut through traffic noise or compete with an amplified band.
04Does it work with keyboards?
Yes. The second channel has stereo L/MONO and R inputs and a TYPE switch that voices it for keyboard as well as guitar.
