This AC adapter is built as a direct replacement for the Harman Kardon Astra HKASTRABLKBSAM wireless speaker. It supplies the correct voltage and connector so the speaker operates exactly as it did with the original charger. The unit is new and fully compatible with the listed device model.

A 10 foot total cord length gives flexibility to place the speaker away from the wall outlet. No internal battery is present; the speaker must remain plugged in for power.
