Charging the battery

Find out how to charge the battery in your product so you can use it on the go.

To charge the battery:

Connect the power supply from the POWER jack on your product to an AC (mains) outlet. The battery light flashes yellow while charging and glows solid green when charged. Typically, the battery will fully charge in about 3 hours; this varies depending on the charge level and if the product is in use while charging. In some cases, it can take up to 10 hours to fully charge.

Plugging in overnight will not overcharge the battery

Lithium batteries have a built-in auto-off feature when a full charge is reached to prevent the battery from being overcharged. Even while still plugged in, the battery level will have to drop below a certain point to trigger the charging again.
