JBL Go 2 Portable Bluetooth Speaker

Linkable you mean via bluetooth or audio jack?
You can use both. You can play music via bluetooth or using an audio jack cable. The speaker only comes with charging cable but not the charging box.

Our JBL Go 2 has a power saving mode which powers off the device when it is not in use for more than 10 minutes. It does have a beeping sound when powering on and off and also when it successfully pairs to a device via Bluetooth.

JBL Go 2 uses technology on its Lithium-Ion batteries that automatically stops charging once they're fully charged. The batteries should not be damaged no matter how long your speaker is plugged in.

Make sure that before use, customers are fully charging the battery (2.5 hours) using the included cable.

- Please make sure customers have the latest software and version of Bluetooth downloaded to their device.

- Bluetooth performance and connectivity can vary based on the environment in which it is being used. For best performance make sure that there is minimal interference (doors, walls, etc) between this speaker and the device transmitting Bluetooth.

- This is designed as an “ultra-portable” speaker which does limit its volume output as compared to other “larger” BT speakers. We make sure that this is called out on the detail page in order to set expectations.
