The rapid charging system in Apex requires 500 ma. (1/2 ampere) to achieve the fastest charge. Most wall chargers can supply this amount of current. Older USB chargers may only be able to charge 100 ma. If you find the charging slower than expected, try another voltage converter. It is also best to avoid devices such as a computer terminal or hub that allow more than one USB cord to be connected. These devices often limit the amount of power available. Your Apex should be switched o during charging to speed the charging process.
