The cable is very short, is placed when not in use once a depression around the speakers around the outside, then the connector is in a recess behind the unit. For storage there is still a small little bag, handy thing.
An LED behind the speaker grill will glow blue or red depending on battery condition.
The battery is, unfortunately, permanently installed, at least I have not found a way opening.
After loading has operating current for 5 hours, the loading takes place by means of a USB cable, which is enclosed.
The speaker has a mini jack and is suitable / intended for operation with MP3 players, laptops, tablets or smartphones.
You can also buy several of these speakers connected in series, stereo is then certainly not be from ;-)
For the holidays etc. the thing is prima suitable because it is nice and small, sound miracles can not be expected here.
Besides a volume control there is no regulation possibilities.
At a high volume, it buzzes slightly, otherwise the sound is ok, but not outstanding.
