The new Fire 7 and Fire 7 Kids are updated tablets from Amazon that sport a slew of upgrades, but most importantly, these now get the USB-C treatment, so you do not have to purchase separate charging accessories.

Though the Fire 7 and Fire 7 Kids retain the same design as the previous-generation models, the majority of the changes are on the inside. For instance, Amazon states that these versions now feature a quad-core CPU that is 30 percent faster and feature twice the RAM. With these upgrades, the Fire 7 tablet range will run smoother, open multiple apps in quick succession, and allow users to switch between those apps faster.
