The AP Adapter is a necessary component designed for charging AR backpack batteries and comes as standard equipment with the AR 1000, AR 2000 and AR 3000. In addition to its charging capabilities, the AP Adapter may be used to power AP Series products with an onboard battery slot when paired with the AP Battery Bag with Connecting Cord and necessary AP battery. This allows users to shift the weight of the battery to their hip or back, depending on whether they are using a battery belt or an AP Battery Backpack.
