Halo chargers may just as good as a manufacturer specific charger depending on the device's specifications, the manufacturer charger's charging capabilities, and the specific Halo charger model in question. Different device use varying amounts of power and may require more than a specific Halo charger offers.
Most Halo charger models come with 2,200 mAh of battery power, which is typically enough for most devices. However, if a device uses battery-consuming applications like video streaming or playing music often, 2,200 mAh Halo chargers might not have enough power to support it. Some Halo chargers offer 2,800 mAh for devices that require extra power.
