Fast Charging :Boost17 Dual USB travel charger adapter with USB Type C cable has been made to supply a maximum of shared 3.4A current to your devices. That way, you are guaranteed a fast charge, no matter which port you use. Boost17 travel charger allows you to charge your devices while keeping a maximum power output of 17W. That allows for the optimum charging of any and all devices you connect to the charger while also giving you less risk of electrical damage to connected devices. Smart IC + Auto ID : Different devices have different power requirements. To ensure your phone or other connected units don’t burn out, we have integrated the smart IC with an Auto ID chipset into the charger PCB. This chipset will accurately estimate the power needed by each plugged unit and only supply that amount. The Auto ID is also important for boosting the charging speed of units attached to the body of the charger simultaneously.
