If the amp rating of the charger is too low, the product may recharge slowly or not at all. Refer to the specifications indicated on the product or within it's owner's guide on for details.

Some products require minimum of 1 amp of current in order to recharge. Many USB ports on a computers can only provide a maximum of 0.5 amps of current. Be sure to use a safety-agency-approved power supply that meets local regulatory requirements (e.g. UL, CSA, VDE, CCC).

Try a different charger.

Charge times can vary based on the charger. Chargers with a higher current rating generally charge products faster than those with a lower rating. Chargers typically list a current rating on the label in Amps (A) or milliamps (mA). A current rating of 1 A / 1000 mA or higher is recommended.
