How to use
Charge the speaker using a standard USB cable connected to a USB charger or power bank until the battery is full. For wireless playback, enable Bluetooth on your source device, find and pair with the ESPERANZA EP145K, then start audio playback. To play files directly, insert a MicroSD card containing compatible audio files into the card slot and select the card source following the device controls. The suction cup can be pressed onto a clean, smooth surface such as glass or ceramic tile to mount the speaker temporarily. Use the built-in microphone to accept or make calls when the speaker is connected to a phone.
Usage recommendations
Keep the suction cup and target surface clean and dry before mounting to ensure a secure hold. Although the speaker has waterproof protection, avoid prolonged submersion and follow common-sense care for charging ports and connectors. Use at modest volume levels for clearer sound and longer battery life; the unit is intended for small spaces and portable use rather than high-volume party coverage.
