Choose an option from the pull down menu above the "Add to Cart" button. This is a Dual "Power Delivery" or PD and QC3.0 charger for devices that use USB type C cables. Devices with a charge port other than USB-C will see no appreciable decrease in charging time. The "Power Delivery" port is USB-C. If using both the USB-C and USB-A ports at the same time both will work but not at as high of a rate as when only one port is being used. This will not prevent your wheelchair from driving like battery chargers do.
