Can the wireless speaker be charged using the USB AC adaptor for an iPhone/iPad?

This unit can be charged using the USB AC adaptor supplied with your iPhone/iPad. Depending on the AC adaptor's specifications (a commercial USB AC adaptor with a potential output of 500 mA), the time required for charging may be extended (10 or more hours*).

*The time it takes for the battery to fully charge while the unit is turned off, and when the battery is completely depleted.

NOTES:

• If you use the unit while it is being charged, the time for charging to complete may be extended. We recommend turning off the unit before charging.
• We recommend charging the unit using a USB AC adaptor with a potential current output of 1.5 A and the USB cable supplied with the unit, or one conforming to USB standards.
• Do not use a "charge-only" USB cable with no data transmission functionality.
