USB PD 2.0 supports fixed voltage at 5V, 9V, 15V and 20V with varying amps. If a charger supports USB PD 2.0 (or 3.0), it can “tell” the device its supported voltages and currents. Although the USB PD standard does not specify the USB connector type, most hardware vendors choose the USB-C connector to make the implementation easier. USB PD 2.0 (up to 100W) is a successor of USB BC 1.2. Some of them are marketed as fast chargers. The open standard is for USB battery charging, and most USB charger manufacturers follow it. 9W charger in the recent Fire HD 10 box offers up to USB BC 1.2 port offers 1.5A (7.5W) charging power.5W USB charger in the box of Fire 7 and Fire HD 8 offers up to 1A5V (5W) charging power.Most USB ports, especially those on laptops, actually supply far lower power. It only offers up to 500mA So it is less than 2.5W.

Latest Fire HD 8 (10th Gen), Fire HD 8 Plus, and Fire HD 2019 (9th Gen) support 15W charging. The maximum output power of the charger.įor the 8″ and 10″ Fire HD tablets with an old micro USB port, the maximum charging power is 5W or 7.5W.The maximum supported charging power of the Fire tablet.So, the maximum charging power is limited by (whichever is lower): Normally, when you connect the Fire tablet to a USB device or charger, the tablet the charger will “negotiate” how much power the tablet can take and how much the charger can offer. The technology, or the standard, behind it is USB Power Delivery (PD) 2.0. So, what is the USB-C fast charging on Fire HD 8 2020 and Fire HD10 2019? Actually, it is not “fast” charging.
