The Enouvation charger provided with your Power Pack is specifically designed to recharge Enouvation Power Packs. Use of a generic charger can be unsafe and cause damage to the Enouvation Power Pack rendering it useless.
If you are using the provided Enouvation charger, you will want to try other outlets in your home. Some outlets can stop working over the years and need to be replaced. We suggest using a GFI outlet or a surge strip with a power indication light to confirm there is power coming from the outlet.
